[Intel-gfx] [PATCH 3/3] i965: check scratch page in a locked fashion on each ioctl

[Rogovin, Kevin]

Hi,

> Per context, then you can remove the locking. It's fitting since the scratch page is per-context anyway.

 The scratch page is per context? This I did not know, I thought it was per PPGTT. If that is the case, then my proposed interface to get/set the scratch page contents is wrong because it does not pass the HW context id.
