[PATCH 2/2] drm/amdgpu/soc15: always load the psp IP module

we can move function amdgpu_ucode_get_load_type to amdgpu_check_arguments(adev);
adev->firmware.load_type will be set.

if user set the load type through module parameters, it is valid for all gpu.

Hi Rex,

I think still initializing the PSP even when you don't need it for firmware upload sounds like a good idea to me.

But take that with a grain of salt since I really on don't know that part of the hardware so well.

Right.  We need PSP for GPU resets among other things.  I also don't really like the fact that we use the module parameter directly to determine whether to load the PSP module or not, we should be using adev->firmware.load_type, but that doesn't get set until later.  We should probably just move that earlier in the common code rather than having it in the soc files.  The problem with checking the module parameter is that that param is gobal so if you you have multiple GPUs, you may get messed up.

Hi Alex,


How about keep the firmware type checking in set_ip_blocks.

and remove the same check code in psp module.

also no need to change load type if psp load firmware failed in psp module.


Please review the attached patch.


Best Regards

Rex

We already handle the firmware loading type checks in the
psp module directly, no need for an additional check.
