HI,
>>- why do we need "surfaceless" support
ChromeOS supports surfacelsess and we need this va enablement for
surfaceless in chromium.
>> - does upstream VAAPI has surfaceless platform
Yes. It uses headless support of VA-API for decoding.
- why is the surfaceless implementation identical to the DRM one
If I understand your question correctly, In case of surfaceless platform
,it uses headless support of VAAPI, which will use drm implementation. If I
miss something here please provide some more details on the question.
Thanks,
Suresh G

Repeating some earlier questions:
- why do we need "surfaceless" support
- does upstream VAAPI has surfaceless platform
- why is the surfaceless implementation identical to the DRM one
Without any additional information, I think you should be using the drm
platform.
Thanks
