Good point, Le, will switch to the existing helper for the cross die access in
v2.

I was hoping the macro could be used for 64bit registers as well. i.e., the aca
regs.

The ret gives us a chance to fallback to legacy query approach (from vbios).
You might want to see patch #3 of the series for more details, go to the
following lines in patch #3
+ /* query ras capability from psp */
+ if (amdgpu_psp_get_ras_capabil

So kernel message has the device pcie bdf information,
which helps issue debugging especially in multiple GPU
system.

Instead of traditional atomfirmware interfaces for RAS
capability, host driver can query ras capability from
psp starting from psp v13_0_6.

Thank you for for fixing this!
I built a custom kernel with this patch on the fedora rawhide kernel
(6.7.0-0.rc8.61.fc40.x86_64) and now the colors look correct. SDR

The check for sending the vsc infopacket to the display was gated behind
PSR (Panel Self Refresh) being enabled.
The vsc infopacket also contains the colorimetry (specifically the
container color gamut) information for the stream on modern DP.
PSR is typically only supported on mobile phone eDP d
