 Owing to the simplicity and near universality of the parallel port interface

 and, if some of the algorithms were built as modules, it's impossible
 to list all of them using, for instance, /proc/crypto or any other
 method. This, however, has an advantage of permitting the usage of
 custom crypto compression modules (implementing S/W or H/W compression).

 Set disk size by writing the value to sysfs node 'disksize'.
 The value can be either in bytes or you can use mem suffixes.

-    * This line of SoCs originates from the XScale family developed by
-      Intel and acquired by Marvell in ~2006. The PXA21x, PXA25x,
-      PXA26x, PXA27x, PXA3xx and PXA93x were developed by Intel, while
-      the later PXA95x were developed by Marvell.
-
-    * Due to their XScale origin, these SoCs have virtually nothing in

-      SoCs, except with the MMP/MMP2 family of SoCs.

-CPU Cores
----------
-
-The XScale cores were designed by Intel, and shipped by Marvell in the older
-PXA processors. Feroceon is a Marvell designed core that developed in-house,
-and that evolved into Sheeva. The XScale and Feroceon cores were phased out
-over time and replaced with Sheeva cores in later products, which subsequently
-got replaced with licensed ARM Cortex-A cores.

-Long-term plans
----------------
-
- * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ into the
-   mach-mvebu/ to support all SoCs from the Marvell EBU (Engineering
-   Business Unit) in a single mach-<foo> directory. The plat-orion/
-   would therefore disappear.
-
- * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
-   directory. The plat-pxa/ would therefore disappear.

+================
+ARM Marvell SoCs
+================
+
+This document lists all the ARM Marvell SoCs that are currently
+supported in mainline by the Linux kernel. As the Marvell families of
+SoCs are large and complex, it is hard to understand where the support
+for a particular SoC is available in the Linux kernel. This document
+tries to help in understanding where those SoCs are supported, and to
+match them with their corresponding public datasheet, when available.

+CPU Cores
+---------
+
+The XScale cores were designed by Intel, and shipped by Marvell in the older
+PXA processors. Feroceon is a Marvell designed core that developed in-house,
+and that evolved into Sheeva. The XScale and Feroceon cores were phased out
+over time and replaced with Sheeva cores in later products, which subsequently
+got replaced with licensed ARM Cortex-A cores.

+Long-term plans
+---------------
+
+ * Unify the mach-dove/, mach-mv78xx0/, mach-orion5x/ into the
+   mach-mvebu/ to support all SoCs from the Marvell EBU (Engineering
+   Business Unit) in a single mach-<foo> directory. The plat-orion/
+   would therefore disappear.
+
+ * Unify the mach-mmp/ and mach-pxa/ into the same mach-pxa
+   directory. The plat-pxa/ would therefore disappear.

 tunables control how the io scheduler works. You can find these entries

 It is possible to change the IO scheduler for a given block device on
 the fly to select one of mq-deadline, none, bfq, or kyber schedulers -
 which can improve that device's throughput.

+ML-AHB interconnect bindings
+
+These bindings describe the STM32 SoCs ML-AHB interconnect bus which connects
+a Cortex-M subsystem with dedicated memories.
+The MCU SRAM and RETRAM memory parts can be accessed through different addresses
+(see "RAM aliases" in [1]) using different buses (see [2]) : balancing the
+Cortex-M firmware accesses among those ports allows to tune the system
+performance.
+
+[1]: https://www.st.com/resource/en/reference_manual/dm00327659.pdf
+[2]: https://wiki.st.com/stm32mpu/wiki/STM32MP15_RAM_mapping
+
+Required properties:
+- compatible: should be "simple-bus"
+- dma-ranges: describes memory addresses translation between the local CPU and
+	   the remote Cortex-M processor. Each memory region, is declared with
+	   3 parameters:
+		 - param 1: device base address (Cortex-M processor address)
+		 - param 2: physical base address (local CPU address)
+		 - param 3: size of the memory region.
+
+The Cortex-M remote processor accessed via the mlahb interconnect is described
+by a child node.
+
+Example:
+mlahb {
+	compatible = "simple-bus";
+	#address-cells = <1>;
+	#size-cells = <1>;
+	dma-ranges = <0x00000000 0x38000000 0x10000>,
+		     <0x10000000 0x10000000 0x60000>,

-Allwinner Reduced Serial Bus (RSB) controller
-
-The RSB controller found on later Allwinner SoCs is an SMBus like 2 wire
-serial bus with 1 master and up to 15 slaves. It is represented by a node
-for the controller itself, and child nodes representing the slave devices.
-
-Required properties :
-
- - reg             : Offset and length of the register set for the controller.
- - compatible      : Shall be "allwinner,sun8i-a23-rsb".
- - interrupts      : The interrupt line associated to the RSB controller.
- - clocks          : The gate clk associated to the RSB controller.
- - resets          : The reset line associated to the RSB controller.
- - #address-cells  : shall be 1
- - #size-cells     : shall be 0
-
-Optional properties :
-
- - clock-frequency : Desired RSB bus clock frequency in Hz. Maximum is 20MHz.
-		     If not set this defaults to 3MHz.
-
-Child nodes:
-
-An RSB controller node can contain zero or more child nodes representing
-slave devices on the bus.  Child 'reg' properties should contain the slave
-device's hardware address. The hardware address is hardwired in the device,
-which can normally be found in the datasheet.
-
-Example:
-
-	rsb@1f03400 {
-		compatible = "allwinner,sun8i-a23-rsb";
-		reg = <0x01f03400 0x400>;
-		interrupts = <0 39 4>;
-		clocks = <&apb0_gates 3>;
-		clock-frequency = <3000000>;
-		resets = <&apb0_rst 3>;
-		#address-cells = <1>;
-		#size-cells = <0>;
-
-		pmic@3e3 {
-			compatible = "...";
-			reg = <0x3e3>;

-			/* ... */

+Binding for Silicon Labs Si5341 and Si5340 programmable i2c clock generator.
+
+Reference
+[1] Si5341 Data Sheet
+    https://www.silabs.com/documents/public/data-sheets/Si5341-40-D-DataSheet.pdf
+[2] Si5341 Reference Manual
+    https://www.silabs.com/documents/public/reference-manuals/Si5341-40-D-RM.pdf
+
+The Si5341 and Si5340 are programmable i2c clock generators with up to 10 output
+clocks. The chip contains a PLL that sources 5 (or 4) multisynth clocks, which
+in turn can be directed to any of the 10 (or 4) outputs through a divider.
+The internal structure of the clock generators can be found in [2].
+
+The driver can be used in "as is" mode, reading the current settings from the
+chip at boot, in case you have a (pre-)programmed device. If the PLL is not
+configured when the driver probes, it assumes the driver must fully initialize
+it.
+
+The device type, speed grade and revision are determined runtime by probing.
+
+The driver currently only supports XTAL input mode, and does not support any
+fancy input configurations. They can still be programmed into the chip and
+the driver will leave them "as is".
+
+==I2C device node==
+
+Required properties:
+- compatible: shall be one of the following:
+	"silabs,si5340" - Si5340 A/B/C/D
+	"silabs,si5341" - Si5341 A/B/C/D
+- reg: i2c device address, usually 0x74
+- #clock-cells: from common clock binding; shall be set to 2.
+	The first value is "0" for outputs, "1" for synthesizers.
+	The second value is the output or synthesizer index.
+- clocks: from common clock binding; list of parent clock  handles,
+	corresponding to inputs. Use a fixed clock for the "xtal" input.
+	At least one must be present.
+- clock-names: One of: "xtal", "in0", "in1", "in2"
+- vdd-supply: Regulator node for VDD
+
+Optional properties:
+- vdda-supply: Regulator node for VDDA
+- vdds-supply: Regulator node for VDDS
+- silabs,pll-m-num, silabs,pll-m-den: Numerator and denominator for PLL
+  feedback divider. Must be such that the PLL output is in the valid range. For
+  example, to create 14GHz from a 48MHz xtal, use m-num=14000 and m-den=48. Only
+  the fraction matters, using 3500 and 12 will deliver the exact same result.
+  If these are not specified, and the PLL is not yet programmed when the driver
+  probes, the PLL will be set to 14GHz.
+- silabs,reprogram: When present, the driver will always assume the device must
+  be initialized, and always performs the soft-reset routine. Since this will
+  temporarily stop all output clocks, don't do this if the chip is generating
+  the CPU clock for example.
+- interrupts: Interrupt for INTRb pin.
+- #address-cells: shall be set to 1.
+- #size-cells: shall be set to 0.
+
+
+== Child nodes: Outputs ==
+
+The child nodes list the output clocks.
+
+Each of the clock outputs can be overwritten individually by using a child node.
+If a child node for a clock output is not set, the configuration remains
+unchanged.
+
+Required child node properties:
+- reg: number of clock output.
+
+Optional child node properties:
+- vdd-supply: Regulator node for VDD for this output. The driver selects default
+	values for common-mode and amplitude based on the voltage.
+- silabs,format: Output format, one of:
+	1 = differential (defaults to LVDS levels)
+	2 = low-power (defaults to HCSL levels)
+	4 = LVCMOS
+- silabs,common-mode: Manually override output common mode, see [2] for values
+- silabs,amplitude: Manually override output amplitude, see [2] for values
+- silabs,synth-master: boolean. If present, this output is allowed to change the
+	multisynth frequency dynamically.
+- silabs,silabs,disable-high: boolean. If set, the clock output is driven HIGH
+	when disabled, otherwise it's driven LOW.
+

+Qualcomm Always-On Subsystem side channel binding
+
+This binding describes the hardware component responsible for side channel
+requests to the always-on subsystem (AOSS), used for certain power management
+requests that is not handled by the standard RPMh interface. Each client in the
+SoC has it's own block of message RAM and IRQ for communication with the AOSS.
+The protocol used to communicate in the message RAM is known as Qualcomm
+Messaging Protocol (QMP)
+
+The AOSS side channel exposes control over a set of resources, used to control
+a set of debug related clocks and to affect the low power state of resources
+related to the secondary subsystems. These resources are exposed as a set of
+power-domains.

+* virtio IOMMU PCI device
+
+When virtio-iommu uses the PCI transport, its programming interface is
+discovered dynamically by the PCI probing infrastructure. However the
+device tree statically describes the relation between IOMMU and DMA
+masters. Therefore, the PCI root complex that hosts the virtio-iommu
+contains a child node representing the IOMMU device explicitly.
+
+Required properties:
+
+- compatible:	Should be "virtio,pci-iommu"
+- reg:		PCI address of the IOMMU. As defined in the PCI Bus
+		Binding reference [1], the reg property is a five-cell
+		address encoded as (phys.hi phys.mid phys.lo size.hi
+		size.lo). phys.hi should contain the device's BDF as
+		0b00000000 bbbbbbbb dddddfff 00000000. The other cells
+		should be zero.
+- #iommu-cells:	Each platform DMA master managed by the IOMMU is assigned
+		an endpoint ID, described by the "iommus" property [2].
+		For virtio-iommu, #iommu-cells must be 1.
+
+Notes:
+
+- DMA from the IOMMU device isn't managed by another IOMMU. Therefore the
+  virtio-iommu node doesn't have an "iommus" property, and is omitted from
+  the iommu-map property of the root complex.
+
+Example:
+

+	compatible = "pci-host-ecam-generic";
+	...
+
+	/* The IOMMU programming interface uses slot 00:01.0 */

-for watchdog operations, ARM-Trusted-Firmware is running at secure EL3 mode and
-it will request system controller to execute the watchdog operation passed from
-Linux kernel.

 2.3 new-device management
+-------------------------
 
  A single lock: "no-new-dev" is used to co-ordinate the addition of
  new devices - this must be synchronized across the array.
  Normally all nodes hold a concurrent-read lock on this device.
 
 3. Communication
+================
 
  Messages can be broadcast to all nodes, and the sender waits for all
  other nodes to acknowledge the message before proceeding.  Only one
  message can be processed at a time.
 
 3.1 Message Types
+-----------------
 
  There are six types of messages which are passed:
 
- 3.1.1 METADATA_UPDATED: informs other nodes that the metadata has
+3.1.1 METADATA_UPDATED
+^^^^^^^^^^^^^^^^^^^^^^
+
+   informs other nodes that the metadata has
    been updated, and the node must re-read the md superblock. This is
    performed synchronously. It is primarily used to signal device
    failure.

    ended so that each node may suspend or resume the region.  Each
    RESYNCING message identifies a range of the devices that the
    sending node is about to resync. This overrides any previous
    notification from that node: only one ranged can be resynced at a
    time per-node.

    isn't clean, then another node is informed to take the ownership of

 3.2 Communication mechanism
+---------------------------
 
  The DLM LVB is used to communicate within nodes of the cluster. There
  are three resources used for the purpose:
 
-  3.2.1 token: The resource which protects the entire communication
+3.2.1 token
+^^^^^^^^^^^

+3.2.3 ack
+^^^^^^^^^
+
+   The resource, acquiring which means the message has been
    acknowledged by all nodes in the cluster. The BAST of the resource
    is used to inform the receiving node that a node wants to
    communicate.
 
 The algorithm is:
 
- 1. receive status - all nodes have concurrent-reader lock on "ack".
+ 1. receive status - all nodes have concurrent-reader lock on "ack"::
+
+	sender                         receiver                 receiver

 How significant is the cache maintenance overhead?

 It depends. Fast eMMC and multiple cache levels with speculative cache
 pre-fetch makes the cache overhead relatively significant. If the DMA
 preparations for the next request are done in parallel with the current
 transfer, the DMA preparation overhead would not affect the MMC performance.

 The intention of non-blocking (asynchronous) MMC requests is to minimize the
 time between when an MMC request ends and another MMC request begins.

 The argument is_first_req in pre_req() indicates that there is no previous

 the performance loss. A way to optimize for this is to split the current

 This figure represents a sector of 256 bytes.
 cp is my abbreviation for column parity, rp for row parity.
 
 Let's start to explain column parity.
-cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.
-so the sum of all bit0, bit2, bit4 and bit6 values + cp0 itself is even.
+
+- cp0 is the parity that belongs to all bit0, bit2, bit4, bit6.
+
+  so the sum of all bit0, bit2, bit4 and bit6 values + cp0 itself is even.
+
 Similarly cp1 is the sum of all bit1, bit3, bit5 and bit7.
-cp2 is the parity over bit0, bit1, bit4 and bit5
-cp3 is the parity over bit2, bit3, bit6 and bit7.
-cp4 is the parity over bit0, bit1, bit2 and bit3.
-cp5 is the parity over bit4, bit5, bit6 and bit7.
+
+- cp2 is the parity over bit0, bit1, bit4 and bit5
+- cp3 is the parity over bit2, bit3, bit6 and bit7.
+- cp4 is the parity over bit0, bit1, bit2 and bit3.
+- cp5 is the parity over bit4, bit5, bit6 and bit7.
+
 Note that each of cp0 .. cp5 is exactly one bit.
 
 Row parity actually works almost the same.
-rp0 is the parity of all even bytes (0, 2, 4, 6, ... 252, 254)
-rp1 is the parity of all odd bytes (1, 3, 5, 7, ..., 253, 255)
-rp2 is the parity of all bytes 0, 1, 4, 5, 8, 9, ...
-(so handle two bytes, then skip 2 bytes).
-rp3 is covers the half rp2 does not cover (bytes 2, 3, 6, 7, 10, 11, ...)
-for rp4 the rule is cover 4 bytes, skip 4 bytes, cover 4 bytes, skip 4 etc.
-so rp4 calculates parity over bytes 0, 1, 2, 3, 8, 9, 10, 11, 16, ...)
-and rp5 covers the other half, so bytes 4, 5, 6, 7, 12, 13, 14, 15, 20, ..
+

-rp8 covers 16 bytes then skips 16 etc
-rp9 skips 16 bytes then covers 16 etc

-rp11 skips 32 bytes then covers 32 etc
-rp12 covers 64 bytes then skips 64 etc
-rp13 skips 64 bytes then covers 64 etc
-rp14 covers 128 bytes then skips 128
-rp15 skips 128 bytes then covers 128

+- rp6 covers 8 bytes then skips 8 etc

+- rp9 skips 16 bytes then covers 16 etc
+- rp10 covers 32 bytes then skips 32 etc

+- rp13 skips 64 bytes then covers 64 etc
+- rp14 covers 128 bytes then skips 128
+- rp15 skips 128 bytes then covers 128
 
 In the end the parity bits are grouped together in three bytes as
 follows:

 ECC    Bit 7 Bit 6 Bit 5 Bit 4 Bit 3 Bit 2 Bit 1 Bit 0
+=====  ===== ===== ===== ===== ===== ===== ===== =====

 I detected after writing this that ST application note AN1823
 (http://www.st.com/stonline/) gives a much
 nicer picture.(but they use line parity as term where I use row parity)
 Oh well, I'm graphically challenged, so suffer with me for a moment :-)

 In this platform we have four DIMMs and two memory controllers in one
 socket.  Each unique interface (BLK or PMEM) to DPA space is identified
 by a region device with a dynamically assigned id (REGION0 - REGION5).
 
     1. The first portion of DIMM0 and DIMM1 are interleaved as REGION0. A
-    single PMEM namespace is created in the REGION0-SPA-range that spans most
-    of DIMM0 and DIMM1 with a user-specified name of "pm0.0". Some of that
-    interleaved system-physical-address range is reclaimed as BLK-aperture
-    accessed space starting at DPA-offset (a) into each DIMM.  In that
-    reclaimed space we create two BLK-aperture "namespaces" from REGION2 and
-    REGION3 where "blk2.0" and "blk3.0" are just human readable names that
-    could be set to any user-desired name in the LABEL.

+Intel MID PTI
+=============
+
+The Intel MID PTI project is HW implemented in Intel Atom
+system-on-a-chip designs based on the Parallel Trace
+Interface for MIPI P1149.7 cJTAG standard.  The kernel solution
+for this platform involves the following files::
+
+	./include/linux/pti.h
+	./drivers/.../n_tracesink.h
+	./drivers/.../n_tracerouter.c
+	./drivers/.../n_tracesink.c
+	./drivers/.../pti.c
+
+pti.c is the driver that enables various debugging features
+popular on platforms from certain mobile manufacturers.
+n_tracerouter.c and n_tracesink.c allow extra system information to
+be collected and routed to the pti driver, such as trace
+debugging data from a modem.  Although n_tracerouter
+and n_tracesink are a part of the complete PTI solution,
+these two line disciplines can work separately from
+pti.c and route any data stream from one /dev/tty node
+to another /dev/tty node via kernel-space.  This provides
+a stable, reliable connection that will not break unless
+the user-space application shuts down (plus avoids
+kernel->user->kernel context switch overheads of routing
+data).
+
+An example debugging usage for this driver system:
+
+  * Hook /dev/ttyPTI0 to syslogd.  Opening this port will also start
+    a console device to further capture debugging messages to PTI.
+  * Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.
+    This is where n_tracerouter and n_tracesink are used.
+  * Hook /dev/pti to a user-level debugging application for writing
+    to PTI HW.
+  * `Use mipi_` Kernel Driver API in other device drivers for
+    debugging to PTI by first requesting a PTI write address via
+    mipi_request_masterchannel(1).
+
+Below is example pseudo-code on how a 'privileged' application
+can hook up n_tracerouter and n_tracesink to any tty on
+a system.  'Privileged' means the application has enough
+privileges to successfully manipulate the ldisc drivers
+but is not just blindly executing as 'root'. Keep in mind
+the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter
+and n_tracesink line discpline drivers but is a generic
+operation for a program to use a line discpline driver
+on a tty port other than the default n_tty::

 Because we wanted to minimize the impact on existing user-level apps using

 EFI uses a slightly different way of representing the time, noticeably

 similar to the struct tm, i.e. struct rtc_time, as used by hwclock.
 One of the reasons for doing it this way is to allow for EFI to still evolve
 without necessarily impacting any of the user applications. The decoupling
 enables flexibility and permits writing wrapper code is ncase things change.
 
 The driver exposes two interfaces, one via the device file and a set of
-ioctl()s. The other is read-only via the /proc filesystem.

+we have created the include/linux/rtc.h header file to contain only the

 in include/linux/mc146818rtc.h.
 
- 
-III/ Time of day service
+
+3. Time of day service
+======================
 
 The part of the driver gives access to the time of day service of EFI.
 Two ioctl()s, compatible with the legacy RTC calls:
 
-	Read the CMOS clock: ioctl(d, RTC_RD_TIME, &rtc);
+	Read the CMOS clock::
+
+		ioctl(d, RTC_RD_TIME, &rtc);
+
+	Write the CMOS clock::
 
-	Write the CMOS clock: ioctl(d, RTC_SET_TIME, &rtc);
+		ioctl(d, RTC_SET_TIME, &rtc);
 
 The rtc is a pointer to a data structure defined in rtc.h which is close
-to a struct tm:
-
-struct rtc_time {
-        int tm_sec;
-        int tm_min;
-        int tm_hour;
-        int tm_mday;
-        int tm_mon;
-        int tm_year;
-        int tm_wday;
-        int tm_yday;
-        int tm_isdst;
-};
+to a struct tm::
+
+  struct rtc_time {
+          int tm_sec;
+          int tm_min;
+          int tm_hour;
+          int tm_mday;
+          int tm_mon;
+          int tm_year;
+          int tm_wday;
+          int tm_yday;
+          int tm_isdst;
+  };
 
 The driver takes care of converting back an forth between the EFI time and
 this format.
 
 Those two ioctl()s can be exercised with the hwclock command:
 
-For reading:
-# /sbin/hwclock --show
-Mon Mar  6 15:32:32 2000  -0.910248 seconds
+For reading::
 
-For setting:
-# /sbin/hwclock --systohc

+	Mon Mar  6 15:32:32 2000  -0.910248 seconds
+
+For setting::
+
+	# /sbin/hwclock --systohc
 
 Root privileges are required to be able to set the time of day.
 
-IV/ Wakeup Alarm service
+4. Wakeup Alarm service
+=======================
 
 EFI provides an API by which one can program when a machine should wakeup,
 i.e. reboot. This is very different from the alarm provided by the legacy
 RTC which is some kind of interval timer alarm. For this reason we don't use
 the same ioctl()s to get access to the service. Instead we have
-introduced 2 news ioctl()s to the interface of an RTC.

+	Read the current state of the alarm::
+

+	Set the alarm or change its status::

-	Set the alarm or change its status
-	ioctl(d, RTC_WKALM_SET, &wkt)
+The wkt structure encapsulates a struct rtc_time + 2 extra fields to get
+status information::

-        struct rtc_time time;

+********************************************************
+Recipe for getting/building/running Xen/ia64 with pv_ops
+********************************************************
+This recipe describes how to get xen-ia64 source and build it,
+and run domU with pv_ops.
+
+Requirements
+============
+
+  - python
+  - mercurial
+    it (aka "hg") is an open-source source code
+    management software. See the below.
+    http://www.selenic.com/mercurial/wiki/
+  - git
+  - bridge-utils
+
+Getting and Building Xen and Dom0
+=================================
+
+  My environment is:
+
+    - Machine  : Tiger4
+    - Domain0 OS  : RHEL5
+    - DomainU OS  : RHEL5
+
+ 1. Download source::
+
+	# hg clone http://xenbits.xensource.com/ext/ia64/xen-unstable.hg
+	# cd xen-unstable.hg
+	# hg clone http://xenbits.xensource.com/ext/ia64/linux-2.6.18-xen.hg
+
+ 2. # make world
+
+ 3. # make install-tools
+
+ 4. copy kernels and xen::
+
+	# cp xen/xen.gz /boot/efi/efi/redhat/
+	# cp build-linux-2.6.18-xen_ia64/vmlinux.gz \
+	/boot/efi/efi/redhat/vmlinuz-2.6.18.8-xen
+
+ 5. make initrd for Dom0/DomU::
+
+	# make -C linux-2.6.18-xen.hg ARCH=ia64 modules_install \
+          O=$(pwd)/build-linux-2.6.18-xen_ia64
+	# mkinitrd -f /boot/efi/efi/redhat/initrd-2.6.18.8-xen.img \
+	  2.6.18.8-xen --builtin mptspi --builtin mptbase \
+	  --builtin mptscsih --builtin uhci-hcd --builtin ohci-hcd \
+	  --builtin ehci-hcd
+
+Making a disk image for guest OS
+================================
+
+ 1. make file::
+
+      # dd if=/dev/zero of=/root/rhel5.img bs=1M seek=4096 count=0
+      # mke2fs -F -j /root/rhel5.img
+      # mount -o loop /root/rhel5.img /mnt
+      # cp -ax /{dev,var,etc,usr,bin,sbin,lib} /mnt
+      # mkdir /mnt/{root,proc,sys,home,tmp}
+
+      Note: You may miss some device files. If so, please create them
+      with mknod. Or you can use tar instead of cp.
+
+ 2. modify DomU's fstab::
+
+      # vi /mnt/etc/fstab
+         /dev/xvda1  /            ext3    defaults        1 1
+         none        /dev/pts     devpts  gid=5,mode=620  0 0

+         none        /sys         sysfs   defaults        0 0
+
+ 3. modify inittab
+
+    set runlevel to 3 to avoid X trying to start::
+
+      # vi /mnt/etc/inittab
+         id:3:initdefault:
+
+    Start a getty on the hvc0 console::
+
+       X0:2345:respawn:/sbin/mingetty hvc0
+
+    tty1-6 mingetty can be commented out
+
+ 4. add hvc0 into /etc/securetty::
+
+      # vi /mnt/etc/securetty (add hvc0)
+
+ 5. umount::
+
+      # umount /mnt
+
+FYI, virt-manager can also make a disk image for guest OS.
+It's GUI tools and easy to make it.
+
+Boot Xen & Domain0
+==================
+
+ 1. replace elilo
+    elilo of RHEL5 can boot Xen and Dom0.
+    If you use old elilo (e.g RHEL4), please download from the below
+    http://elilo.sourceforge.net/cgi-bin/blosxom
+    and copy into /boot/efi/efi/redhat/::
+
+      # cp elilo-3.6-ia64.efi /boot/efi/efi/redhat/elilo.efi
+
+ 2. modify elilo.conf (like the below)::
+
+      # vi /boot/efi/efi/redhat/elilo.conf
+      prompt
+      timeout=20
+      default=xen
+      relocatable
+
+      image=vmlinuz-2.6.18.8-xen
+             label=xen
+             vmm=xen.gz
+             initrd=initrd-2.6.18.8-xen.img
+             read-only
+             append=" -- rhgb root=/dev/sda2"
+
+The append options before "--" are for xen hypervisor,
+the options after "--" are for dom0.
+
+FYI, your machine may need console options like
+"com1=19200,8n1 console=vga,com1". For example,
+append="com1=19200,8n1 console=vga,com1 -- rhgb console=tty0 \
+console=ttyS0 root=/dev/sda2"
+
+Getting and Building domU with pv_ops
+=====================================
+
+ 1. get pv_ops tree::
+
+      # git clone http://people.valinux.co.jp/~yamahata/xen-ia64/linux-2.6-xen-ia64.git/
+
+ 2. git branch (if necessary)::
+
+      # cd linux-2.6-xen-ia64/
+      # git checkout -b your_branch origin/xen-ia64-domu-minimal-2008may19
+
+   Note:
+     The current branch is xen-ia64-domu-minimal-2008may19.
+     But you would find the new branch. You can see with
+     "git branch -r" to get the branch lists.
+
+       http://people.valinux.co.jp/~yamahata/xen-ia64/for_eagl/linux-2.6-ia64-pv-ops.git/
+
+     is also available.
+
+     The tree is based on
+
+      git://git.kernel.org/pub/scm/linux/kernel/git/aegl/linux-2.6 test)
+
+ 3. copy .config for pv_ops of domU::
+
+      # cp arch/ia64/configs/xen_domu_wip_defconfig .config
+
+ 4. make kernel with pv_ops::
+
+      # make oldconfig
+      # make
+
+ 5. install the kernel and initrd::
+
+      # cp vmlinux.gz /boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU
+      # make modules_install
+      # mkinitrd -f /boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img \
+        2.6.26-rc3xen-ia64-08941-g1b12161 --builtin mptspi \
+        --builtin mptbase --builtin mptscsih --builtin uhci-hcd \
+        --builtin ohci-hcd --builtin ehci-hcd
+
+Boot DomainU with pv_ops
+========================
+
+ 1. make config of DomU::
+
+     # vi /etc/xen/rhel5
+       kernel = "/boot/efi/efi/redhat/vmlinuz-2.6-pv_ops-xenU"
+       ramdisk = "/boot/efi/efi/redhat/initrd-2.6-pv_ops-xenU.img"
+       vcpus = 1
+       memory = 512
+       name = "rhel5"
+       disk = [ 'file:/root/rhel5.img,xvda1,w' ]
+       root = "/dev/xvda1 ro"
+       extra= "rhgb console=hvc0"
+
+ 2. After boot xen and dom0, start xend::
+
+	# /etc/init.d/xend start
+
+   ( In the debugging case, `# XEND_DEBUG=1 xend trace_start` )
+
+ 3. start domU::
+
+	# xm create -c rhel5

+
+
+	usage::

+
+
+		Ok, this is where problems start.  The current interface for
+		the CDROM_DISC_STATUS ioctl is flawed.  It makes the false
+		assumption that CDs are all CDS_DATA_1 or all CDS_AUDIO, etc.
+		Unfortunately, while this is often the case, it is also
+		very common for CDs to have some tracks with data, and some
+		tracks with audio.	Just because I feel like it, I declare
+		the following to be the best way to cope.  If the CD has
+		ANY data tracks on it, it will be returned as a data CD.
+		If it has any XA tracks, I will return it as that.	Now I
+		could simplify this interface by combining these returns with
+		the above, but this more clearly demonstrates the problem
+		with the current interface.  Too bad this wasn't designed
+		to use bitmasks...	       -Erik
+
+		Well, now we have the option CDS_MIXED: a mixed-type CD.
+		User level programmers might feel the ioctl is not very
+		useful.

-	  the same address.
-
-	  MSF values are converted to LBA values via this formula:

-
-	error return:
-	  ENOSYS	Drive is not capable of reading MCN data.
-
-	notes:
-	  Source code comments state:
-
-	    The following function is implemented, although very few
-	    audio discs give Universal Product Code information, which
-	    should just be the Medium Catalog Number on the box.  Note,
-	    that the way the code is written on the CD is /not/ uniform

-
-	error returns:	none at present
-
-	notes:
-	  Source code comments state:
-
-	    Ok, this is where problems start.  The current interface for
-	    the CDROM_DISC_STATUS ioctl is flawed.  It makes the false
-	    assumption that CDs are all CDS_DATA_1 or all CDS_AUDIO, etc.
-	    Unfortunately, while this is often the case, it is also
-	    very common for CDs to have some tracks with data, and some
-	    tracks with audio.	Just because I feel like it, I declare
-	    the following to be the best way to cope.  If the CD has
-	    ANY data tracks on it, it will be returned as a data CD.
-	    If it has any XA tracks, I will return it as that.	Now I
-	    could simplify this interface by combining these returns with
-	    the above, but this more clearly demonstrates the problem
-	    with the current interface.  Too bad this wasn't designed
-	    to use bitmasks...	       -Erik
-
-	    Well, now we have the option CDS_MIXED: a mixed-type CD.
-	    User level programmers might feel the ioctl is not very
-	    useful.

+Ioctl Numbers
+=============
+
+19 October 1999
+
+Michael Elizabeth Chastain
+<mec@shout.net>
+
+If you are adding new ioctl's to the kernel, you should use the _IO
+macros defined in <linux/ioctl.h>:
+
+    ====== == ============================================
+    _IO    an ioctl with no parameters
+    _IOW   an ioctl with write parameters (copy_from_user)
+    _IOR   an ioctl with read parameters  (copy_to_user)
+    _IOWR  an ioctl with both write and read parameters.
+    ====== == ============================================
+
+'Write' and 'read' are from the user's point of view, just like the
+system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
+be _IOW, although the kernel would actually read data from user space;
+a GET_FOO ioctl would be _IOR, although the kernel would actually write
+data to user space.
+
+The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
+or number from the table below.  Because of the large number of drivers,
+many drivers share a partial letter with other drivers.
+
+If you are writing a driver for a new device and need a letter, pick an
+unused block with enough room for expansion: 32 to 256 ioctl commands.
+You can register the block by patching this file and submitting the
+patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
+I'll register one for you.
+
+The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
+to distinguish ioctls from each other.  The third argument to _IOW,
+_IOR, or _IOWR is the type of the data going into the kernel or coming
+out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
+sizeof(arg) as the third argument as this results in your ioctl thinking
+it passes an argument of type size_t.
+
+Some devices use their major number as the identifier; this is OK, as
+long as it is unique.  Some devices are irregular and don't follow any
+convention at all.
+
+Following this convention is good because:
+
+(1) Keeping the ioctl's globally unique helps error checking:
+    if a program calls an ioctl on the wrong device, it will get an
+    error rather than some unexpected behaviour.
+
+(2) The 'strace' build procedure automatically finds ioctl numbers
+    defined with _IO, _IOW, _IOR, or _IOWR.
+
+(3) 'strace' can decode numbers back into useful names when the
+    numbers are unique.
+
+(4) People looking for ioctls can grep for them more easily when
+    this convention is used to define the ioctl numbers.
+
+(5) When following the convention, the driver code can use generic
+    code to copy the parameters between user and kernel space.
+
+This table lists ioctls visible from user land for Linux/x86.  It contains
+most drivers up to 2.6.31, but I know I am missing some.  There has been
+no attempt to list non-X86 architectures or ioctls from drivers/staging/.

-Ioctl Numbers
-19 October 1999
-Michael Elizabeth Chastain
-<mec@shout.net>
-
-If you are adding new ioctl's to the kernel, you should use the _IO
-macros defined in <linux/ioctl.h>:
-
-    _IO    an ioctl with no parameters
-    _IOW   an ioctl with write parameters (copy_from_user)
-    _IOR   an ioctl with read parameters  (copy_to_user)
-    _IOWR  an ioctl with both write and read parameters.
-
-'Write' and 'read' are from the user's point of view, just like the
-system calls 'write' and 'read'.  For example, a SET_FOO ioctl would
-be _IOW, although the kernel would actually read data from user space;
-a GET_FOO ioctl would be _IOR, although the kernel would actually write
-data to user space.
-
-The first argument to _IO, _IOW, _IOR, or _IOWR is an identifying letter
-or number from the table below.  Because of the large number of drivers,
-many drivers share a partial letter with other drivers.
-
-If you are writing a driver for a new device and need a letter, pick an
-unused block with enough room for expansion: 32 to 256 ioctl commands.
-You can register the block by patching this file and submitting the
-patch to Linus Torvalds.  Or you can e-mail me at <mec@shout.net> and
-I'll register one for you.
-
-The second argument to _IO, _IOW, _IOR, or _IOWR is a sequence number
-to distinguish ioctls from each other.  The third argument to _IOW,
-_IOR, or _IOWR is the type of the data going into the kernel or coming
-out of the kernel (e.g.  'int' or 'struct foo').  NOTE!  Do NOT use
-sizeof(arg) as the third argument as this results in your ioctl thinking
-it passes an argument of type size_t.
-
-Some devices use their major number as the identifier; this is OK, as
-long as it is unique.  Some devices are irregular and don't follow any
-convention at all.
-
-Following this convention is good because:
-
-(1) Keeping the ioctl's globally unique helps error checking:
-    if a program calls an ioctl on the wrong device, it will get an
-    error rather than some unexpected behaviour.
-
-(2) The 'strace' build procedure automatically finds ioctl numbers
-    defined with _IO, _IOW, _IOR, or _IOWR.
-
-(3) 'strace' can decode numbers back into useful names when the
-    numbers are unique.
-
-(4) People looking for ioctls can grep for them more easily when
-    this convention is used to define the ioctl numbers.
-
-(5) When following the convention, the driver code can use generic
-    code to copy the parameters between user and kernel space.
-
-This table lists ioctls visible from user land for Linux/x86.  It contains
-most drivers up to 2.6.31, but I know I am missing some.  There has been
-no attempt to list non-X86 architectures or ioctls from drivers/staging/.

+
+With these hooks we provide the following statistics:
+
+ con-bounces
+	- number of lock contention that involved x-cpu data
+ contentions
+	- number of lock acquisitions that had to wait
+ wait time
+     min
+	- shortest (non-0) time we ever had to wait for a lock

+     max
+	- longest time we ever held the lock
+     total
+	- total time this lock was held
+     avg
+	- average time this lock was held
+
+These numbers are gathered per lock class, per read/write state (when
+applicable).
+
+It also tracks 4 contention points per class. A contention point is a call site
+that had to wait on lock acquisition.
+
+Configuration
+-------------
+
+Lock statistics are enabled via CONFIG_LOCK_STAT.
+
+Usage
+-----
+
+Enable collection of statistics::
+
+	# echo 1 >/proc/sys/kernel/lock_stat
+
+Disable collection of statistics::
+
+	# echo 0 >/proc/sys/kernel/lock_stat
+
+Look at the current lock statistics::

+This excerpt shows the first two lock class statistics. Line 01 shows the
+output version - each time the format changes this will be updated. Line 02-04
+show the header with column descriptions. Lines 05-18 and 20-31 show the actual
+statistics. These statistics come in two parts; the actual stats separated by a
+short separator (line 08, 13) from the contention points.
+
+Lines 09-12 show the first 4 recorded contention points (the code
+which tries to get the lock) and lines 14-17 show the first 4 recorded
+contended points (the lock holder). It is possible that the max
+con-bounces point is missing in the statistics.
+
+The first lock (05-18) is a read/write lock, and shows two lines above the
+short separator. The contention points don't match the column descriptors,
+they have two: contentions and [<IP>] symbol. The second set of contention
+points are the points we're contending with.
+
+The integer part of the time values is in us.

+Dealing with nested locks, subclasses may appear::

-LOCK STATISTICS
-
-- WHAT
-
-As the name suggests, it provides statistics on locks.
-
-- WHY
-
-Because things like lock contention can severely impact performance.
-
-- HOW
-
-Lockdep already has hooks in the lock functions and maps lock instances to
-lock classes. We build on that (see Documentation/locking/lockdep-design.txt).
-The graph below shows the relation between the lock functions and the various
-hooks therein.
-
-        __acquire
-            |
-           lock _____
-            |        \
-            |    __contended
-            |         |
-            |       <wait>
-            | _______/
-            |/
-            |
-       __acquired
-            |
-            .

-         unlock
-
-lock, unlock	- the regular lock functions
-__*		- the hooks
-<> 		- states
-
-With these hooks we provide the following statistics:
-
- con-bounces       - number of lock contention that involved x-cpu data
- contentions       - number of lock acquisitions that had to wait
- wait time min     - shortest (non-0) time we ever had to wait for a lock
-           max     - longest time we ever had to wait for a lock
-	   total   - total time we spend waiting on this lock
-	   avg     - average time spent waiting on this lock
- acq-bounces       - number of lock acquisitions that involved x-cpu data
- acquisitions      - number of times we took the lock
- hold time min     - shortest (non-0) time we ever held the lock
-	   max     - longest time we ever held the lock
-	   total   - total time this lock was held
-	   avg     - average time this lock was held
-
-These numbers are gathered per lock class, per read/write state (when
-applicable).
-
-It also tracks 4 contention points per class. A contention point is a call site
-that had to wait on lock acquisition.
-
- - CONFIGURATION
-
-Lock statistics are enabled via CONFIG_LOCK_STAT.
-
- - USAGE
-
-Enable collection of statistics:
-
-# echo 1 >/proc/sys/kernel/lock_stat
-
-Disable collection of statistics:
-

-Lines 09-12 show the first 4 recorded contention points (the code
-which tries to get the lock) and lines 14-17 show the first 4 recorded
-contended points (the lock holder). It is possible that the max
-con-bounces point is missing in the statistics.

-The first lock (05-18) is a read/write lock, and shows two lines above the
-short separator. The contention points don't match the column descriptors,
-they have two: contentions and [<IP>] symbol. The second set of contention
-points are the points we're contending with.

-The Intel MID PTI project is HW implemented in Intel Atom
-system-on-a-chip designs based on the Parallel Trace
-Interface for MIPI P1149.7 cJTAG standard.  The kernel solution
-for this platform involves the following files:
-
-./include/linux/pti.h
-./drivers/.../n_tracesink.h
-./drivers/.../n_tracerouter.c
-./drivers/.../n_tracesink.c
-./drivers/.../pti.c
-
-pti.c is the driver that enables various debugging features
-popular on platforms from certain mobile manufacturers.
-n_tracerouter.c and n_tracesink.c allow extra system information to
-be collected and routed to the pti driver, such as trace
-debugging data from a modem.  Although n_tracerouter
-and n_tracesink are a part of the complete PTI solution,
-these two line disciplines can work separately from
-pti.c and route any data stream from one /dev/tty node
-to another /dev/tty node via kernel-space.  This provides
-a stable, reliable connection that will not break unless
-the user-space application shuts down (plus avoids
-kernel->user->kernel context switch overheads of routing
-data).
-
-An example debugging usage for this driver system:
-   *Hook /dev/ttyPTI0 to syslogd.  Opening this port will also start
-    a console device to further capture debugging messages to PTI.
-   *Hook /dev/ttyPTI1 to modem debugging data to write to PTI HW.
-    This is where n_tracerouter and n_tracesink are used.
-   *Hook /dev/pti to a user-level debugging application for writing
-    to PTI HW.
-   *Use mipi_* Kernel Driver API in other device drivers for
-    debugging to PTI by first requesting a PTI write address via
-    mipi_request_masterchannel(1).
-
-Below is example pseudo-code on how a 'privileged' application
-can hook up n_tracerouter and n_tracesink to any tty on
-a system.  'Privileged' means the application has enough
-privileges to successfully manipulate the ldisc drivers
-but is not just blindly executing as 'root'. Keep in mind
-the use of ioctl(,TIOCSETD,) is not specific to the n_tracerouter
-and n_tracesink line discpline drivers but is a generic
-operation for a program to use a line discpline driver
-on a tty port other than the default n_tty.

+				Boot image header in RISC-V Linux
+			=============================================
+
+Author: Atish Patra <atish.patra@wdc.com>
+Date  : 20 May 2019
+
+This document only describes the boot image header details for RISC-V Linux.
+The complete booting guide will be available at Documentation/riscv/booting.txt.
+
+The following 64-byte header is present in decompressed Linux kernel image.
+
+	u32 code0;		  /* Executable code */
+	u32 code1; 		  /* Executable code */
+	u64 text_offset;	  /* Image load offset, little endian */
+	u64 image_size;		  /* Effective Image size, little endian */
+	u64 flags;		  /* kernel flags, little endian */
+	u32 version;		  /* Version of this header */
+	u32 res1  = 0;		  /* Reserved */
+	u64 res2  = 0;    	  /* Reserved */
+	u64 magic = 0x5643534952; /* Magic number, little endian, "RISCV" */
+	u32 res3;		  /* Reserved for additional RISC-V specific header */
+	u32 res4;		  /* Reserved for PE COFF offset */
+
+This header format is compliant with PE/COFF header and largely inspired from
+ARM64 header. Thus, both ARM64 & RISC-V header can be combined into one common
+header in future.
+
+Notes:
+- This header can also be reused to support EFI stub for RISC-V in future. EFI
+  specification needs PE/COFF image header in the beginning of the kernel image
+  in order to load it as an EFI application. In order to support EFI stub,
+  code0 should be replaced with "MZ" magic string and res5(at offset 0x3c) should
+  point to the rest of the PE/COFF header.
+
+- version field indicate header version number.
+	Bits 0:15  - Minor version
+	Bits 16:31 - Major version
+
+  This preserves compatibility across newer and older version of the header.
+  The current version is defined as 0.1.
+
+- res3 is reserved for offset to any other additional fields. This makes the
+  header extendible in future. One example would be to accommodate ISA
+  extension for RISC-V in future. For current version, it is set to be zero.
+
+- In current header, the flag field has only one field.
+	Bit 0: Kernel endianness. 1 if BE, 0 if LE.
+
+- Image size is mandatory for boot loader to load kernel image. Booting will
+  fail otherwise.

-    .weight: The 'influence' of a particular cooling device on this

-             devices. For example, if all cooling devices have a
-             weight of 1, then they all contribute the same. You can
-             use percentages if you want, but it's not mandatory. A
-             weight of 0 means that this cooling device doesn't
-             contribute to the cooling of this zone unless all cooling
-             devices have a weight of 0. If all weights are 0, then
-             they all contribute the same.
-    .trip_mask:This is a bit mask that gives the binding relation between
-               this thermal zone and cdev, for a particular trip point.
-               If nth bit is set, then the cdev and thermal zone are bound

-    .binding_limits: This is an array of cooling state limits. Must have

+		     exactly 2 * thermal_zone.number_of_trip_points. It is an
+		     array consisting of tuples <lower-state upper-state> of

+User Memory Access
+------------------
+Kprobe events supports user-space memory access. For that purpose, you can use
+either user-space dereference syntax or 'ustring' type.
+
+The user-space dereference syntax allows you to access a field of a data
+structure in user-space. This is done by adding the "u" prefix to the
+dereference syntax. For example, +u4(%si) means it will read memory from the
+address in the register %si offset by 4, and the memory is expected to be in
+user-space. You can use this for strings too, e.g. +u0(%si):string will read
+a string from the address in the register %si that is expected to be in user-
+space. 'ustring' is a shortcut way of performing the same task. That is,
++0(%si):ustring is equivalent to +u0(%si):string.
+
+Note that kprobe-event provides the user-memory access syntax but it doesn't
+use it transparently. This means if you use normal dereference or string type
+for user memory, it might fail, and may always fail on some archs. The user
+has to carefully check if the target data is in kernel or user space.

+ZONE_DEVICE
+===========
+The `ZONE_DEVICE` facility builds upon `SPARSEMEM_VMEMMAP` to offer
+`struct page` `mem_map` services for device driver identified physical
+address ranges. The "device" aspect of `ZONE_DEVICE` relates to the fact
+that the page objects for these address ranges are never marked online,
+and that a reference must be taken against the device, not just the page
+to keep the memory pinned for active use. `ZONE_DEVICE`, via
+:c:func:`devm_memremap_pages`, performs just enough memory hotplug to
+turn on :c:func:`pfn_to_page`, :c:func:`page_to_pfn`, and
+:c:func:`get_user_pages` service for the given range of pfns. Since the
+page reference count never drops below 1 the page is never tracked as
+free memory and the page's `struct list_head lru` space is repurposed
+for back referencing to the host device / driver that mapped the memory.
+
+While `SPARSEMEM` presents memory as a collection of sections,
+optionally collected into memory blocks, `ZONE_DEVICE` users have a need
+for smaller granularity of populating the `mem_map`. Given that
+`ZONE_DEVICE` memory is never marked online it is subsequently never
+subject to its memory ranges being exposed through the sysfs memory
+hotplug api on memory block boundaries. The implementation relies on
+this lack of user-api constraint to allow sub-section sized memory
+ranges to be specified to :c:func:`arch_add_memory`, the top-half of
+memory hotplug. Sub-section support allows for 2MB as the cross-arch
+common alignment granularity for :c:func:`devm_memremap_pages`.
+
+The users of `ZONE_DEVICE` are:
+
+* pmem: Map platform persistent memory to be used as a direct-I/O target
+  via DAX mappings.
+
+* hmm: Extend `ZONE_DEVICE` with `->page_fault()` and `->page_free()`
+  event callbacks to allow a device-driver to coordinate memory management
+  events related to device-memory, typically GPU memory. See
+  Documentation/vm/hmm.rst.
+
+* p2pdma: Create `struct page` objects to allow peer devices in a
+  PCI/-E topology to coordinate direct-DMA operations between themselves,
+  i.e. bypass host memory.

-MMUv3 initialization sequence.
-
-The code in the initialize_mmu macro sets up MMUv3 memory mapping
-identically to MMUv2 fixed memory mapping. Depending on
-CONFIG_INITIALIZE_XTENSA_MMU_INSIDE_VMLINUX symbol this code is
-located in addresses it was linked for (symbol undefined), or not
-(symbol defined), so it needs to be position-independent.
-
-The code has the following assumptions:
-  This code fragment is run only on an MMU v3.
-  TLBs are in their reset state.
-  ITLBCFG and DTLBCFG are zero (reset state).
-  RASID is 0x04030201 (reset state).
-  PS.RING is zero (reset state).
-  LITBASE is zero (reset state, PC-relative literals); required to be PIC.
-
-TLB setup proceeds along the following steps.
-
-  Legend:
-    VA = virtual address (two upper nibbles of it);
-    PA = physical address (two upper nibbles of it);
-    pc = physical range that contains this code;
-
-After step 2, we jump to virtual address in the range 0x40000000..0x5fffffff
-or 0x00000000..0x1fffffff, depending on whether the kernel was loaded below
-0x40000000 or above. That address corresponds to next instruction to execute
-in this code. After step 4, we jump to intended (linked) address of this code.
-The scheme below assumes that the kernel is loaded below 0x40000000.

-The default location of IO peripherals is above 0xf0000000. This may be changed
-using a "ranges" property in a device tree simple-bus node. See the Devicetree
-Specification, section 4.5 for details on the syntax and semantics of
-simple-bus nodes. The following limitations apply:
-
-1. Only top level simple-bus nodes are considered
-
-2. Only one (first) simple-bus node is considered
-
-3. Empty "ranges" properties are not supported
-
-4. Only the first triplet in the "ranges" property is considered
-
-5. The parent-bus-address value is rounded down to the nearest 256MB boundary
-
-6. The IO area covers the entire 256MB segment of parent-bus-address; the
-   "ranges" triplet length field is ignored

+	 * - The only source of DP is the single native Type C port.
+	 * - On cheza we want to be able to hook DP up to _either_ of the
+	 *   two Type C connectors and want to be able to achieve 4 lanes of DP.
+	 * - When you configure a Type C port for 4 lanes of DP you lose USB3.
+	 * - In order to make everything work, the native Type C port is always
+	 *   configured as 4-lanes DP so it's always available.
+	 * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
+	 *   sent to the two Type C connectors.
+	 * - The extra USB2 lines from the native Type C port are always
+	 *   setup as "peripheral" so that we can mux them over to one connector
+	 *   or the other if someone needs the connector configured as a gadget
+	 *   (but they only get USB2 speeds).
+	 *
+	 * All the hardware muxes would allow us to hook things up in different
+	 * ways to some potential benefit for static configurations (you could
+	 * achieve extra USB2 bandwidth by using two different ports for the
+	 * two conenctors or possibly even get USB3 peripheral mode), but in

+	 * Errata:
+	 * When CPU raise #NPF on guest data access and vCPU CR4.SMAP=1, it is
+	 * possible that CPU microcode implementing DecodeAssist will fail
+	 * to read bytes of instruction which caused #NPF. In this case,
+	 * GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly
+	 * return 0 instead of the correct guest instruction bytes.
+	 *
+	 * This happens because CPU microcode reading instruction bytes
+	 * uses a special opcode which attempts to read data using CPL=0
+	 * priviledges. The microcode reads CS:RIP and if it hits a SMAP
+	 * fault, it gives up and returns no instruction bytes.
+	 *
+	 * Detection:
+	 * We reach here in case CPU supports DecodeAssist, raised #NPF and
+	 * returned 0 in GuestIntrBytes field of the VMCB.
+	 * First, errata can only be triggered in case vCPU CR4.SMAP=1.
+	 * Second, if vCPU CR4.SMEP=1, errata could only be triggered
+	 * in case vCPU CPL==3 (Because otherwise guest would have triggered
+	 * a SMEP fault instead of #NPF).
+	 * Otherwise, vCPU CR4.SMEP=0, errata could be triggered by any vCPU CPL.
+	 * As most guests enable SMAP if they have also enabled SMEP, use above
+	 * logic in order to attempt minimize false-positive of detecting errata
+	 * while still preserving all cases semantic correctness.
+	 *
+	 * Workaround:
+	 * To determine what instruction the guest was executing, the hypervisor
+	 * will have to decode the instruction at the instruction pointer.

- * Xen selfballoon driver (and optional frontswap self-shrinking driver)
- *
- * Copyright (c) 2009-2011, Dan Magenheimer, Oracle Corp.
- *
- * This code complements the cleancache and frontswap patchsets to optimize
- * support for Xen Transcendent Memory ("tmem").  The policy it implements
- * is rudimentary and will likely improve over time, but it does work well
- * enough today.
- *
- * Two functionalities are implemented here which both use "control theory"
- * (feedback) to optimize memory utilization. In a virtualized environment
- * such as Xen, RAM is often a scarce resource and we would like to ensure
- * that each of a possibly large number of virtual machines is using RAM
- * efficiently, i.e. using as little as possible when under light load
- * and obtaining as much as possible when memory demands are high.
- * Since RAM needs vary highly dynamically and sometimes dramatically,
- * "hysteresis" is used, that is, memory target is determined not just
- * on current data but also on past data stored in the system.
- *
- * "Selfballooning" creates memory pressure by managing the Xen balloon
- * driver to decrease and increase available kernel memory, driven
- * largely by the target value of "Committed_AS" (see /proc/meminfo).
- * Since Committed_AS does not account for clean mapped pages (i.e. pages
- * in RAM that are identical to pages on disk), selfballooning has the
- * affect of pushing less frequently used clean pagecache pages out of
- * kernel RAM and, presumably using cleancache, into Xen tmem where
- * Xen can more efficiently optimize RAM utilization for such pages.
- *
- * When kernel memory demand unexpectedly increases faster than Xen, via
- * the selfballoon driver, is able to (or chooses to) provide usable RAM,
- * the kernel may invoke swapping.  In most cases, frontswap is able
- * to absorb this swapping into Xen tmem.  However, due to the fact
- * that the kernel swap subsystem assumes swapping occurs to a disk,
- * swapped pages may sit on the disk for a very long time; even if
- * the kernel knows the page will never be used again.  This is because
- * the disk space costs very little and can be overwritten when
- * necessary.  When such stale pages are in frontswap, however, they
- * are taking up valuable real estate.  "Frontswap selfshrinking" works
- * to resolve this:  When frontswap activity is otherwise stable
- * and the guest kernel is not under memory pressure, the "frontswap
- * selfshrinking" accounts for this by providing pressure to remove some
- * pages from frontswap and return them to kernel memory.
- *
- * For both "selfballooning" and "frontswap-selfshrinking", a worker
- * thread is used and sysfs tunables are provided to adjust the frequency
- * and rate of adjustments to achieve the goal, as well as to disable one
- * or both functions independently.

- * While some argue that this functionality can and should be implemented
- * in userspace, it has been observed that bad things happen (e.g. OOMs).
- *
- * System configuration note: Selfballooning should not be enabled on
- * systems without a sufficiently large swap device configured; for best
- * results, it is recommended that total swap be increased by the size
- * of the guest memory. Note, that selfballooning should be disabled by default
- * if frontswap is not configured.  Similarly selfballooning should be enabled
- * by default if frontswap is configured and can be disabled with the
- * "tmem.selfballooning=0" kernel boot option.  Finally, when frontswap is
- * configured, frontswap-selfshrinking can be disabled  with the
- * "tmem.selfshrink=0" kernel boot option.
- *
- * Selfballooning is disallowed in domain0 and force-disabled.

 --------------
 Each probe argument follows below syntax.
 
- [NAME=]LOCALVAR|$retval|%REG|@SYMBOL[:TYPE]
+ [NAME=]LOCALVAR|$retval|%REG|@SYMBOL[:TYPE][@user]
 
 'NAME' specifies the name of this argument (optional). You can use the name of local variable, local data structure member (e.g. var->field, var.field2), local array with fixed index (e.g. array[1], var->array[0], var->pointer[2]), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.)
 '$vars' and '$params' special arguments are also available for NAME, '$vars' is expanded to the local variables (including function parameters) which can access at given probe point. '$params' is expanded to only the function parameters.
 'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo (*). Currently, basic types (u8/u16/u32/u64/s8/s16/s32/s64), hexadecimal integers (x/x8/x16/x32/x64), signedness casting (u/s), "string" and bitfield are supported. (see TYPES for detail)
 On x86 systems %REG is always the short form of the register: for example %AX. %RAX or %EAX is not valid.
+"@user" is a special attribute which means the LOCALVAR will be treated as a user-space memory. This is only valid for kprobe event.
