For mediatek mt8173, the GPU driver is powervr and for mediatek
mt8183, the GPU driver is panfrost. So add support in drm-ci to
test panfrost and powervr GPU driver for mediatek SOCs and update
xfails. Powervr driver was merged in linux kernel, but there's no
mediatek support yet. So disable the mt8173-gpu job which uses
powervr driver.

Add panfrost specific tests to testlist and skip KMS tests for
panfrost driver since it is not a not a KMS driver. Also update
the MAINTAINERS file to include xfails for panfrost driver.

Hi Vignesh, thanks for your work.

I'm still wondering about a few things, please check below.

---

v2:
   - Add panfrost and PVR GPU jobs for mediatek SOC with new xfails, add xfail
     entry to MAINTAINERS.

Maybe we should review how the xfails failes are named. I think they should start with the DRIVER_NAME instead of GPU_VERSION.

For instance, consider the following job:

mediatek:mt8183-gpu:
  extends:
    - .mt8183
  variables:
    GPU_VERSION: mediatek-mt8183-gpu
    DRIVER_NAME: panfrost

And we have mediatek-mt8183-gpu-skips.txt

If there is an error, we want to notify the panfrost driver maintainers (and maybe not the mediatek driver maintainers), so MAINTAINERS file doesn't correspond to this.

How about a naming <driver name>_<hardware/gpu>_<type: gpu/display> ?

powervr_mediatek-mt8173_gpu-skipts.txt
mediatek_mediatek-mt8173_display-skipts.txt
panfrost_mediatek-mt8183_gpu-skips.txt
mediatek_mediatek-mt8183_display-skips.txt
...

What do you think?

Thanks
Helen




v3:
   - Add panfrost specific tests to testlist and skip KMS tests for
     panfrost driver since it is not a not a KMS driver and update xfails.
     Update the MAINTAINERS file to include xfails for panfrost driver.
     Add the job name in GPU_VERSION and use it for xfail file names instead
     of using DRIVER_NAME.
