We want to be able to explicitly migrate objects between gem memory
regions, initially for display and dma-buf, but there might be more
use-cases coming up.
Introduce a gem migrate interface, add a selftest and use it for
display fb pinning and dma-buf mapping.
This series should make accelerated desktop work on DG1 with DG1-enabled
OpenGL.
v2:
- Address review comments by Matthew Auld on patch 1/5. More details on
the patch commit message.
- Address a dma-buf locking issue pointed out by Michael Ruhl, and
add a selftest to catch that issue moving forward.
- Rebase the dma-buf migration patch on the above-mentioned fix.
v3:
- Fix i915_gem_object_can_migrate() to return true if object is already in
the correct region, even if the object ops doesn't have a migrate()
callback.
- Update typo in commit message.
