[v2,0/7] drm/panfrost: Add heap and no execute buffer allocation

Message

Rob Herring (Arm) July 25, 2019, 1:09 a.m. UTC

This series adds new BO allocation flags PANFROST_BO_HEAP and
PANFROST_BO_NOEXEC. The heap allocations are paged in on GPU page faults.

This is based on drm-misc-next. A branch is here[1].

  drm/panfrost: Split panfrost_mmu_map SG list mapping to its own
    function
  drm/panfrost: Add a no execute flag for BO allocations
  drm/panfrost: Add support for GPU heap allocations
  drm/panfrost: Bump driver version to 1.1
