amd/display: downgrade validation failure log level

2021-09-30T08:11:06+00:00

[ Upstream commit 7bbee36d71502ab9a341505da89a017c7ae2e6b2 ]

In amdgpu_dm_atomic_check, dc_validate_global_state is called. On
failure this logs a warning to the kernel journal. However warnings
shouldn't be used for atomic test-only commit failures: user-space
might be perfoming a lot of atomic test-only commits to find the
best hardware configuration.

Downgrade the log to a regular DRM atomic message. While at it, use
the new device-aware logging infrastructure.

This fixes error messages in the kernel when running gamescope [1].

treewide: Change list_sort to use const pointers

2021-09-30T08:11:04+00:00

[ Upstream commit 4f0f586bf0c898233d8f316f471a21db2abd522d ]

list_sort() internally casts the comparison function passed to it
to a different type with constant struct list_head pointers, and
uses this pointer to call the functions, which trips indirect call
Control-Flow Integrity (CFI) checking.

Instead of removing the consts, this change defines the
list_cmp_func_t type and changes the comparison function types of
all list_sort() callers to use const pointers, thus avoiding type
mismatches.

drm/amd/pm: Update intermediate power state for SI

2021-09-30T08:11:01+00:00

commit ab39d3cef526ba09c4c6923b4cd7e6ec1c5d4faa upstream.

Update the current state as boot state during dpm initialization.
During the subsequent initialization, set_power_state gets called to
transition to the final power state. set_power_state refers to values
from the current state and without current state populated, it could
result in NULL pointer dereference.

For ex: on platforms where PCI speed change is supported through ACPI
ATCS method, the link speed of current state needs to be queried before
deciding on changing to final power state's link speed. The logic to query
ATCS-support was broken on certain platforms. The issue became visible
when broken ATCS-support logic got fixed with commit
f9b7f3703ff9 ("drm/amdgpu/acpi: make ATPX/ATCS structures global (v2)").

drm/nouveau/nvkm: Replace -ENOSYS with -ENODEV

2021-09-26T12:09:02+00:00

commit e8f71f89236ef82d449991bfbc237e3cb6ea584f upstream.

nvkm test builds fail with the following error.

  drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c: In function 'nvkm_control_mthd_pstate_info':
  drivers/gpu/drm/nouveau/nvkm/engine/device/ctrl.c:60:35: error: overflow in conversion from 'int' to '__s8' {aka 'signed char'} changes value from '-251' to '5'

The code builds on most architectures, but fails on parisc where ENOSYS
is defined as 251.

Replace the error code with -ENODEV (-19).  The actual error code does
not really matter and is not passed to userspace - it just has to be
negative.

drm/amdgpu: Disable PCIE_DPM on Intel RKL Platform

2021-09-26T12:08:59+00:00

[ Upstream commit b3dc549986eb7b38eba4a144e979dc93f386751f ]

Due to high latency in PCIE clock switching on RKL platforms,
switching the PCIE clock dynamically at runtime can lead to HDMI/DP
audio problems. On newer asics this is handled in the SMU firmware.
For SMU7-based asics, disable PCIE clock switching to avoid the issue.

AMD provide a parameter to disable PICE_DPM.

modprobe amdgpu ppfeaturemask=0xfff7bffb

It's better to contorl PCIE_DPM in amd gpu driver,
switch PCI_DPM by determining intel RKL platform for SMU7-based asics.

drm/rockchip: cdn-dp-core: Make cdn_dp_core_resume __maybe_unused

2021-09-22T10:27:57+00:00

commit 040b8907ccf1c78d020aca29800036565d761d73 upstream.

With the new static annotation, the compiler warns when the functions
are actually unused:

   drivers/gpu/drm/rockchip/cdn-dp-core.c:1123:12: error: 'cdn_dp_resume' defined but not used [-Werror=unused-function]
    1123 | static int cdn_dp_resume(struct device *dev)
         |            ^~~~~~~~~~~~~

Mark them __maybe_unused to suppress that warning as well.

[ Not so 'new' static annotations any more, and I removed the part of
  the patch that added __maybe_unused to cdn_dp_suspend(), because it's
  used by the shutdown/remove code.

  So only the resume function ends up possibly unused if CONFIG_PM isn't
  set     - Linus ]
