[Linux-graphics-maintainer] [PATCH 2/3] drm/ttm: move memory accounting into vmwgfx v3

Mon Feb 8 13:35:16 UTC 2021


Hi Zack,

ok we figured out how to do this correctly.

Basically using the pdev->kobj instead of the drm->primary->kdev->kobj 
pointer worked quite well.

I've just send the latest patches to the mailing list. If you don't have 
any objections I will commit that tomorrow with your and Daniels rb.

Thanks,
Christian.
