disabled in PPTable. Disable hwmon knobs for fan control also as

Memory allocations should be done in sw_init. hw_init should
just be hardware programming needed to initialize the IP block.
This is how most other IP blocks work. Move the GPU memory
allocations from psp hw_init to psp sw_init and move the memory
free to sw_fini. This also fixes a potential GPU memory leak
if psp hw_init fails.

When disabling LPIs, a guest needs to poll GICR_CTLR.RWP in order

Start tracking this state during which LPIs are being disabled,

We also take this opportunity to disallow enabling LPIs and programming

As reported by Alan, the CFI (Call Frame Information) in the VDSO time
routines is incorrect since commit ce7d8056e38b ("powerpc/vdso: Prepare
for switching VDSO to generic C implementation.").
DWARF has a concept called the CFA (Canonical Frame Address), which on
powerpc is calculated as an offset from the stack pointer (r1). That
means when the stack pointer is changed there must be a corresponding
CFI directive to update the calculation of the CFA.
The current code is missing those directives for the changes to r1,
which prevents gdb from being able to generate a backtrace from inside
VDSO functions, eg:
Breakpoint 1, 0x00007ffff7f804dc in __kernel_clock_gettime ()
(gdb) bt
#0 0x00007ffff7f804dc in __kernel_clock_gettime ()
#1 0x00007ffff7d8872c in clock_gettime@@GLIBC_2.17 () from /lib64/libc.so.6
#2 0x00007fffffffd960 in ?? ()
#3 0x00007ffff7d8872c in clock_gettime@@GLIBC_2.17 () from /lib64/libc.so.6
Backtrace stopped: frame did not save the PC
Alan helpfully describes some rules for correctly maintaining the CFI information:
1) Every adjustment to the current frame address reg (ie. r1) must be
described, and exactly at the instruction where r1 changes. Why?
Because stack unwinding might want to access previous frames.
2) If a function changes LR or any non-volatile register, the save
location for those regs must be given. The CFI can be at any
instruction after the saves up to the point that the reg is
changed.
(Exception: LR save should be described before a bl. not after)
3) If asychronous unwind info is needed then restores of LR and
non-volatile regs must also be described. The CFI can be at any
instruction after the reg is restored up to the point where the
save location is (potentially) trashed.
Fix the inability to backtrace by adding CFI directives describing the
changes to r1, ie. satisfying rule 1.
Also change the information for LR to point to the copy saved on the
stack, not the value in r0 that will be overwritten by the function
call.
Finally, add CFI directives describing the save/restore of r2.
With the fix gdb can correctly back trace and navigate up and down the stack:
Breakpoint 1, 0x00007ffff7f804dc in __kernel_clock_gettime ()
(gdb) bt
#0 0x00007ffff7f804dc in __kernel_clock_gettime ()

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
It replaces the VOP unit found in the older Rockchip SoCs.
This driver has been derived from the downstream Rockchip Kernel and
heavily modified:
- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between
functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs
The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
board. Overlay support is tested with the modetest utility. AFBC support
on the cluster windows is tested with weston-simple-dmabuf-egl on
weston using the (yet to be upstreamed) panfrost driver support.

Current port description doesn't cover all possible cases. It currently
expects one single port with two endpoints.
When the HDMI connector is described in the device tree there can be two
ports, first one going to the VOP and the second one going to the connector.
Also on SoCs which only have a single VOP there will be only one
endpoint instead of two.
This patch addresses both issues. With this there can either be a single
port ("port") , or two of them ("port@0", "port@1") when the connector
is also in the device tree. Also the first or only port can either have
one endpoint ("endpoint") for single VOP SoCs or two ("endpoint@0",
"endpoint@1") for dual VOP SoCs.

The user can change the QoS credits dynamically with the
management console interface which notifies OS with sysfs. After
returning from the OS interface successfully, the management
console updates the hypervisor. Since the VAS capabilities in
the hypervisor is not updated when the OS gets the update,
the kernel is using the old total credits value from the
hypervisor. Fix this issue by using the new QoS credits
from the userspace instead of depending on VAS capabilities
from the hypervisor.

Currently, the directory name used to create a nullb device through
sysfs is not used as the device name, potentially causing headaches for
users if devices are already created through the modprobe operation
withe the nr_device module parameter not set to 0. E.g. a user can do
"mkdir /sys/kernel/config/nullb/nullb0" to create a nullb device even
though /dev/nullb0 was already created by modprobe. In this case, the
configfs nullb device will be named nullb1, causing confusion for the
user.
Simplify this by using the configfs directory name as the nullb device
name, always, unless another nullb device is already using the same
name. E.g. if modprobe created nullb0, then:
$ mkdir /sys/kernel/config/nullb/nullb0
mkdir: cannot create directory '/sys/kernel/config/nullb/nullb0': File
exists
will be reported to the user.
To implement this, the function null_find_dev_by_name() is added to
check for the existence of a nullb device with the name used for a new
configfs device directory. nullb_group_make_item() uses this new
function to check if the directory name can be used as the disk name.
Finally, null_add_dev() is modified to use the device config item name
as the disk name for a new nullb device created using configfs.
The naming of devices created though modprobe remains unchanged.
Of note is that it is possible for a user to create through configfs a
nullb device with the same name as an existing device. E.g.
$ mkdir /sys/kernel/config/nullb/null
will successfully create the nullb device named "null" but this block
device will however not appear under /dev/ since /dev/null already
exists.

Use bdev_discard_alignment to calculate the correct discard alignment
offset even for partitions instead of just looking at the queue limit.
Also switch to use bdev_discard_granularity to get rid of the last direct
queue reference in xen_blkbk_discard.

Value of macro MIDR_IMPLEMENTOR_MASK exceeds the range of integer
and can lead to overflow. Currently there is no issue as it is used
in expressions implicitly casting it to u32. To avoid possible
problems, fix the macro.

It is possibe that probe failure issue happens when the device
and its child_device's probe happens at the same time.
In coresight_make_links, has_conns_grp is true for parent, but
has_conns_grp is false for child device as has_conns_grp is set
to true in coresight_create_conns_sysfs_group. The probe of parent
device will fail at this condition. Add has_conns_grp check for
child device before make the links and make the process from
device_register to connection_create be atomic to avoid this
probe failure issue.

Since internal_flags is only 8 bits, we can only have one
more internal flag. However, we can obviously never use all
of possible the combinations, in fact, we only use 14 of
them (including no flags).
Since we want more flags for MLO (multi-link operation) in
the future, refactor the code to use a flags selector, so
wrap all of the .internal_flags assignments in a IFLAGS()
macro which selects the combination according to the pre-
defined list of combinations.
When we need a new combination, we'll have to add it, but
again we will never use all possible combinations.
