From dd17c8f72993f9461e9c19250e3f155d6d99df22 Mon Sep 17 00:00:00 2001 From: Rusty Russell Date: Thu, 29 Oct 2009 22:34:15 +0900 Subject: percpu: remove per_cpu__ prefix. Now that the return from alloc_percpu is compatible with the address of per-cpu vars, it makes sense to hand around the address of per-cpu variables. To make this sane, we remove the per_cpu__ prefix we used created to stop people accidentally using these vars directly. Now we have sparse, we can use that (next patch). tj: * Updated to convert stuff which were missed by or added after the original patch. * Kill per_cpu_var() macro.

Peter Anvin" Date: Mon, 4 Jan 2010 16:16:06 -0800 Subject: x86, apic: Reclaim IDT vectors 0x20-0x2f Reclaim 16 IDT vectors and make them available for general allocation. Reclaim vectors 0x20-0x2f by reallocating the IRQ_MOVE_CLEANUP_VECTOR to vector 0x1f. This is in the range of vector numbers that is officially reserved for the CPU (for exceptions), however, the use of the APIC to generate any vector 0x10 or above is documented, and the CPU internally can receive any vector number (the legacy BIOS uses INT 0x08-0x0f for interrupts, as messed up as that is.) Since IRQ_MOVE_CLEANUP_VECTOR has to be alone in the lowest-numbered priority level (block of 16), this effectively enables us to reclaim an otherwise-unusable APIC priority level and put it to use. Since this is a transient kernel-only allocation we can change it at any time, and if/when there is an exception at vector 0x1f this assignment needs to be changed as part of OS enabling that new feature.

Peter Anvin" Date: Mon, 4 Jan 2010 21:14:41 -0800 Subject: x86, apic: Don't waste a vector to improve vector spread We want to use a vector-assignment sequence that avoids stumbling onto 0x80 earlier in the sequence, in order to improve the spread of vectors across priority levels on machines with a small number of interrupt sources. Right now, this is done by simply making the first vector (0x31 or 0x41) completely unusable. This is unnecessary; all we need is to start assignment at a +1 offset, we don't actually need to prohibit the usage of this vector once we have wrapped around. Signed-off-by: H.

Based on the server workload, OSPM can request what frequency it expects from a logical CPU, and the BIOS will achieve that frequency transparently. This patch introduces driver support for PCC. OSPM uses the PCC driver to communicate with the BIOS via the PCC interface. There is a Documentation file that provides a link to the PCC Specification, and also provides a summary of the PCC interface. Currently, certain HP ProLiant platforms implement the PCC interface. However, any platform whose BIOS implements the PCC Specification, can utilize this driver. V2 --> V1 changes (based on Dominik's suggestions): - Removed the dependency on CPU_FREQ_TABLE - "cpufreq_stats" will no longer PANIC. Actually, it will not load anymore because it is not applicable. - Removed the sanity check for target frequency in the ->target routine. NOTE: A patch to sanitize the target frequency requested by "ondemand" is needed to ensure that the target freq < policy->min. Can this driver be queued up for the 2.6.33 tree?

Introduction: +---------------- +Processor Clocking Control (PCC) is an interface between the platform +firmware and OSPM. It is a mechanism for coordinating processor +performance (ie: frequency) between the platform firmware and the OS. + +The PCC driver (pcc-cpufreq) allows OSPM to take advantage of the PCC +interface. + +OS utilizes the PCC interface to inform platform firmware what frequency the +OS wants for a logical processor. The platform firmware attempts to achieve +the requested frequency. If the request for the target frequency could not be +satisfied by platform firmware, then it usually means that power budget +conditions are in place, and "power capping" is taking place. + +1.1 PCC interface: +------------------ +The complete PCC specification is available here: +http://www.acpica.org/download/Processor-Clocking-Control-v1p0.pdf + +PCC relies on a shared memory region that provides a channel for communication +between the OS and platform firmware. PCC also implements a "doorbell" that +is used by the OS to inform the platform firmware that a command has been +sent. + +The ACPI PCCH() method is used to discover the location of the PCC shared +memory region. The shared memory region header contains the "command" and +"status" interface. PCCH() also contains details on how to access the platform +doorbell. + +The following commands are supported by the PCC interface: +* Get Average Frequency +* Set Desired Frequency + +The ACPI PCCP() method is implemented for each logical processor and is +used to discover the offsets for the input and output buffers in the shared +memory region. + +When PCC mode is enabled, the platform will not expose processor performance +or throttle states (_PSS, _TSS and related ACPI objects) to OSPM. Therefore, +the native P-state driver (such as acpi-cpufreq for Intel, powernow-k8 for +AMD) will not load. + +However, OSPM remains in control of policy. The governor (eg: "ondemand") +computes the required performance for each processor based on server workload. +The PCC driver fills in the command interface, and the input buffer and +communicates the request to the platform firmware. The platform firmware is +responsible for delivering the requested performance. + +Each PCC command is "global" in scope and can affect all the logical CPUs in +the system. Therefore, PCC is capable of performing "group" updates. With PCC +the OS is capable of getting/setting the frequency of all the logical CPUs in +the system with a single call to the BIOS. + +1.1.1 Get Average Frequency: +---------------------------- +This command is used by the OSPM to query the running frequency of the +processor since the last time this command was completed. The output buffer +indicates the average unhalted frequency of the logical processor expressed as +a percentage of the nominal (ie: maximum) CPU frequency. The output buffer +also signifies if the CPU frequency is limited by a power budget condition. + +1.1.2 Set Desired Frequency: +---------------------------- +This command is used by the OSPM to communicate to the platform firmware the +desired frequency for a logical processor. The output buffer is currently +ignored by OSPM. The next invocation of "Get Average Frequency" will inform +OSPM if the desired frequency was achieved or not. + +1.2 Platforms affected: +----------------------- +The PCC driver will load on any system where the platform firmware: +* supports the PCC interface, and the associated PCCH() and PCCP() methods +* assumes responsibility for managing the hardware clocking controls in order +to deliver the requested processor performance + +Currently, certain HP ProLiant platforms implement the PCC interface. On those +platforms PCC is the "default" choice. + +However, it is possible to disable this interface via a BIOS setting. In +such an instance, as is also the case on platforms where the PCC interface +is not implemented, the PCC driver will fail to load silently. + +2. Driver and /sys details: +--------------------------- +When the driver loads, it merely prints the lowest and the highest CPU +frequencies supported by the platform firmware. + +The PCC driver loads with a message such as: +pcc-cpufreq: (v1.00.00) driver loaded with frequency limits: 1600 MHz, 2933 +MHz + +This means that the OPSM can request the CPU to run at any frequency in +between the limits (1600 MHz, and 2933 MHz) specified in the message. + +Internally, there is no need for the driver to convert the "target" frequency +to a corresponding P-state. + +The VERSION number for the driver will be of the format v.xy.ab. +eg: 1.00.02 + ----- -- + | | + | -- this will increase with bug fixes/enhancements to the driver + |-- this is the version of the PCC specification the driver adheres to + + +The following is a brief discussion on some of the fields exported via the +/sys filesystem and how their values are affected by the PCC driver: + +2.1 scaling_available_frequencies: +---------------------------------- +scaling_available_frequencies is not created in /sys. No intermediate +frequencies need to be listed because the BIOS will try to achieve any +frequency, within limits, requested by the governor. A frequency does not have +to be strictly associated with a P-state. + +2.2 cpuinfo_transition_latency: +------------------------------- +The cpuinfo_transition_latency field is 0. The PCC specification does +not include a field to expose this value currently. + +2.3 cpuinfo_cur_freq: +--------------------- +A) Often cpuinfo_cur_freq will show a value different than what is declared +in the scaling_available_frequencies or scaling_cur_freq, or scaling_max_freq. +This is due to "turbo boost" available on recent Intel processors. If certain +conditions are met the BIOS can achieve a slightly higher speed than requested +by OSPM. An example: + +scaling_cur_freq : 2933000 +cpuinfo_cur_freq : 3196000 + +B) There is a round-off error associated with the cpuinfo_cur_freq value. +Since the driver obtains the current frequency as a "percentage" (%) of the +nominal frequency from the BIOS, sometimes, the values displayed by +scaling_cur_freq and cpuinfo_cur_freq may not match. An example: + +scaling_cur_freq : 1600000 +cpuinfo_cur_freq : 1583000 + +In this example, the nominal frequency is 2933 MHz. The driver obtains the +current frequency, cpuinfo_cur_freq, as 54% of the nominal frequency: + + 54% of 2933 MHz = 1583 MHz + +Nominal frequency is the maximum frequency of the processor, and it usually +corresponds to the frequency of the P0 P-state. + +2.4 related_cpus: +----------------- +The related_cpus field is identical to affected_cpus. + +affected_cpus : 4 +related_cpus : 4 + +Currently, the PCC driver does not evaluate _PSD. The platforms that support +PCC do not implement SW_ALL. So OSPM doesn't need to perform any coordination +to ensure that the same frequency is requested of all dependent CPUs. + +3. Caveats: +----------- +The "cpufreq_stats" module in its present form cannot be loaded and +expected to work with the PCC driver. Since the "cpufreq_stats" module +provides information wrt each P-state, it is not applicable to the PCC driver. diff --git a/arch/x86/kernel/cpu/cpufreq/Kconfig b/arch/x86/kernel/cpu/cpufreq/Kconfig index f138c6c389b9..870e6cc6ad28 100644 --- a/arch/x86/kernel/cpu/cpufreq/Kconfig +++ b/arch/x86/kernel/cpu/cpufreq/Kconfig @@ -10,6 +10,20 @@ if CPU_FREQ comment "CPUFreq processor drivers" +config X86_PCC_CPUFREQ + tristate "Processor Clocking Control interface driver" + depends on ACPI && ACPI_PROCESSOR + help + This driver adds support for the PCC interface. + + For details, take a look at: + . + + To compile this driver as a module, choose M here: the + module will be called pcc-cpufreq. + + If in doubt, say N. + config X86_ACPI_CPUFREQ tristate "ACPI Processor P-States driver" select CPU_FREQ_TABLE diff --git a/arch/x86/kernel/cpu/cpufreq/Makefile b/arch/x86/kernel/cpu/cpufreq/Makefile index 509296df294d..1840c0a5170b 100644 --- a/arch/x86/kernel/cpu/cpufreq/Makefile +++ b/arch/x86/kernel/cpu/cpufreq/Makefile @@ -4,6 +4,7 @@ obj-$(CONFIG_X86_POWERNOW_K8) += powernow-k8.o obj-$(CONFIG_X86_ACPI_CPUFREQ) += acpi-cpufreq.o +obj-$(CONFIG_X86_PCC_CPUFREQ) += pcc-cpufreq.o obj-$(CONFIG_X86_POWERNOW_K6) += powernow-k6.o obj-$(CONFIG_X86_POWERNOW_K7) += powernow-k7.o obj-$(CONFIG_X86_LONGHAUL) += longhaul.o diff --git a/arch/x86/kernel/cpu/cpufreq/pcc-cpufreq.c b/arch/x86/kernel/cpu/cpufreq/pcc-cpufreq.c new file mode 100644 index 000000000000..29368854533c --- /dev/null +++ b/arch/x86/kernel/cpu/cpufreq/pcc-cpufreq.c @@ -0,0 +1,621 @@ +/* + * pcc-cpufreq.c - Processor Clocking Control firmware cpufreq interface + * + * Copyright (C) 2009 Red Hat, Matthew Garrett + * Copyright (C) 2009 Hewlett-Packard Development Company, L.P. + * Nagananda Chumbalkar + * + * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; version 2 of the License. + * + * This program is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE, GOOD TITLE or NON + * INFRINGEMENT.

This removes the need for a seperate array of pointers to clocks. Fix a minor problem of re-initialising the pointers in s3c6400_set_clksrc() as this is also called by the cpufreq code. Move these initialisations to the code that does the registration. Based on Harald Welte's original clock changes patch.

Reduce the size of struct clk by 12 bytes and make defining clocks with common implementation functions easier by moving the set_rate, get_rate, round_rate and set_parent calls into a new structure called 'struct clk_ops' and using that instead. This change does make a few clocks larger as they need their own clk_ops, but this is outweighed by the number of clocks with either no ops or having a common set of ops. Update all the users of this.

Since the spdif clock relies on the audio clock, move the audio clocks into their own arrary. Thanks to Marek Szyprowski for testing and pointing out the four clocks what where missed from the clock list.

The select defaults to 8-bit mode so without config the Ethernet doesn't work. This patch uses the new SROM definitions to set nCS1 to the state found in the Samsung U-Boot port for 6410. It may be more conservative that it needs to be since those settings were marked as for CS8900A also using this chip select. But this change is enough to get the ethernet working when booted with Qi.

Also we don't need to reserve the entire privilege level (all 16 vectors in the priority bucket that IRQ_MOVE_CLEANUP_VECTOR falls into), as the x86 architecture (section 10.9.3 in SDM Vol3a) specifies that with in the priority level, the higher the vector number the higher the priority. And hence we don't need to reserve the complete priority level 0x20-0x2f for the IRQ migration cleanup logic. So change the IRQ_MOVE_CLEANUP_VECTOR to 0x20 and allow 0x21-0x2f to be used for device interrupts. 0x30-0x3f will be used for ISA interrupts (these also can be migrated in the context of IOAPIC and hence need to be at a higher priority level than IRQ_MOVE_CLEANUP_VECTOR).

Note, we didn't move this to gpiolib.c as it contains code that is not strictly for gpiolib support and the 4bit code is already called gpiolib.c so make the change easier by not renaming both files in one go.

If these IRQ's are handled by legacy pic controller, then the kernel handles them only on cpu 0. So there is no need to block this vector space on all cpu's. Similarly if these IRQ's are handled by IO-APIC, then the IRQ affinity will determine on which cpu's we need allocate the vector resource for that particular IRQ. This can be done dynamically and here also there is no need to block 16 vectors for IRQ0..IRQ15 on all cpu's. Fix this by initially assigning IRQ0..IRQ15 to IRQ0_VECTOR..IRQ15_VECTOR's only on cpu 0. If the legacy controllers like pic handles these irq's, then this configuration will be fixed. If more modern controllers like IO-APIC handle these IRQ's, then we start with this configuration and as IRQ's migrate, vectors (/and cpu's) associated with these IRQ's change dynamically. This will freeup the block of 16 vectors on other cpu's which don't handle IRQ0..IRQ15, which can now be used for other IRQ's that the particular cpu handle.
