- Would we need a different firmware version with a different "hdr"
for the amdgpu driver?
Yes, we should probably release the latest one instead of reusing the
one used with radeon.
BTW: Does VCE work on CIK? Alex, don't we run into the same issue there
as well?
- Wouldn't it be better to continue loading the driver while having
VCE disabled IF we fail when loading or validating the FW? Completely
failing to load the driver for this reason seems overkill IMO, since
nothing has been loaded in memory and no registry have been modified
up to that point.
UVD and VCE are actually needed for correct power management. When the
blocks fail to initialize you usually sooner or later run into problems
with power management (e.g. stuck inside a certain power level).
- Would it be a good idea to send a patch as a RFC so some of you
could help me finish the job and maybe pinpoint where the last
modifications need to be done?
Well you could, but to be honest without AMD releasing new firmware that
is most likely a futile effort.

Christian.

Hi,
I've been working on porting VCE1 from radeon to amdgpu in the last
few weeks. I'm pretty much done and I've enabled the functionality to
see how it goes. However, I ended up with an error on the firmware
validation (size doesn't seem to fit), thus failing completely in
loading the driver. I'm testing on a R9 280X (Tahiti).
Three questions then:
- Would we need a different firmware version with a different "hdr"
for the amdgpu driver?
- Wouldn't it be better to continue loading the driver while having
VCE disabled IF we fail when loading or validating the FW? Completely
