Public bug reported:
[ Impact ]
Currently, when the amdgpu driver tries to load firmware that is
optional and fails, it emits error:
Direct firmware load for amdgpu/%s.bin failed with error -2
In the situations where the firmware is optional, this should be treated
as false alarm. The driver should emit this message only when missing
necessary firmware.
[ Fix ]
Backport the following patch and its dependent patches:
ea5d49349894 drm/amd: Add the capability to mark certain firmware as
"required"
This patch makes it possible to specify if a firmware is necessary for
amdgpu, and use the *_nowarn variant of firmware loading functions for
optional firmware, so that the kernel doesn't emit error if the firmware
is not found.
[ Test ]
0. Find a machine where the ISP firmware is optional
1. Install and boot the kernel
2. The graphic should work as expected
3. The dmesg shouldn't show the "Direct firmware load for amdgpu/%s.bin failed
with error -2" message
[ Where the problem could occur]
If some necessary firmware is marked as optional, and the firmware fails
to load, it will fail silently.
