Hi all,
Another iteration that takes into account :
- Tvrtko's nits from v7 on patch 8
- Tvrtko's suggestion not to return EPERM when dynamic sseu is
disabled through sysfs. Instead store the requested value and
apply it when/if dynamic sseu becomes enabled.
- A pretty important fix that prevented the MI_SDRI to be applied.
We were writting into a GGTT offset which didn't work (tests have
been updated to catch this). To address this, this iteration adds
patch 6 that creates a view of the context images into the kernel
context's PPGTT so that we can properly modify them from the
kernel context.
Many thanks to Chris & Tvrtko for review & discussions.
Cheers,
