[igt-dev] [PATCH i-g-t 0/2] Introduce new apis for coherent mmap

[Sreedhar Telukuntla]

This patch introduces two new coherent mmap functions for tests.

gem_mmap__device_coherent_domain api maps buffer object and returns
the memory domain to be used by the caller for subsequent set_domain
call for cpu access.

gem_mmap__device_coherent_sync api maps buffer object and also does
set_domain to make the memory ready for cpu access.

gem_ctx_shared tests were modified to use the new functions 

Sreedhar Telukuntla (2):
  lib/i915/gem_mman: Add coherent mmap api support with set domain
  tests/i915/gem_ctx_shared: Use gem_mmap__device_coherent_sync api
