      drm/amdgpu: remove unsafe optimization to drop preamble ib · 7d9c70d2
      Jiansong Chen authored 
      Take the situation with gfxoff, the optimization may cause
corrupt CE ram contents. In addition emit_cntxcntl callback
has similar optimization which firmware can handle properly
even for power feature.

      drm/amdgpu: Add vbios info ioctl interface · 29b4c589
      Jiawei Gu authored 
      Add AMDGPU_INFO_VBIOS_INFO subquery id for detailed vbios info.

Provides a way for the user application to get the VBIOS
information without having to parse the binary.
It is useful for the user to be able to display in a simple way the VBIOS
version in their system if they happen to encounter an issue.

V2:
Use numeric serial.
Parse and expose vbios version string.

V3:
Remove redundant data in drm_amdgpu_info_vbios struct.

V4:
64 bit alignment in drm_amdgpu_info_vbios.

v5: squash together all the reverts, etc. (Alex)

      drm/amd/display: fix warning: ‘update_dsc_caps’ and ‘apply_dsc_policy_for_stream’ defined but not used

Fixes gcc '-Wunused-function' warning:

‘update_dsc_caps’ and ‘apply_dsc_policy_for_stream’ are only used
if 'CONFIG_DRM_AMD_DC_DCN' is defined,

however, it's defined even if 'CONFIG_DRM_AMD_DC_DCN' is not defined.
Thus gcc will report following warning
if 'CONFIG_DRM_AMD_DC_DCN' is not defined:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5572:13: warning:
‘apply_dsc_policy_for_stream’ defined but not used [-Wunused-function]

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:5556:13: warning:
‘update_dsc_caps’ defined but not used [-Wunused-function]

Thus move the definition of ‘update_dsc_caps’ and
‘apply_dsc_policy_for_stream’ inside define macro to fix it.

      drm/amd/display: Avoid HDCP over-read and corruption · 06888d57
      Kees Cook authored 
      Instead of reading the desired 5 bytes of the actual target field,
the code was reading 8. This could result in a corrupted value if the
trailing 3 bytes were non-zero, so instead use an appropriately sized
and zero-initialized bounce buffer, and read only 5 bytes before casting
to u64.
