[Mesa-dev] [Mesa-stable] [PATCH 2/2] auxiliary: use vl_drm_screen_create method for surfaceless

[Guttula, Suresh]

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.
