Subject: [PATCH 00/22] LMEM basics
Date: Fri, 27 Sep 2019 18:33:47 +0100	[thread overview]
Message-ID: <20190927173409.31175-1-matthew.auld@intel.com> (raw)

The basic LMEM bits, minus the uAPI, pruning, etc. The goal is to support
basic LMEM object creation within the kernel. From there we can start with the
dumb buffer support, and then the other display related bits.

We still have a few patches that deal with lack of MAPPABLE_APERTURE support,
though we can probably split that into its own series.

Patches 1-2 are just noise.
Patches 3-6 are the basic intel_memory_region bits + basic mock_selftests.
Patches 7-11 are the basic LMEM region bits + basic live_selftests.
Patches 12-14 try to turn stolen + shmem into intel_region_regions.
Patches 15-21 implement the !MAPPABLE_APERTURE bits.

The fake LMEM patch allows us to run the live_selftests with LMEM enabled and
!HAS_MAPPABLE_APERTURE in CI.

Abdiel Janulgue (4):
  drm/i915: Add memory region information to device_info
  drm/i915: setup io-mapping for LMEM
  drm/i915/lmem: support kernel mapping
  drm/i915: enumerate and init each supported region

CQ Tang (1):
  drm/i915: check for missing aperture in GTT pread/pwrite paths

Daniele Ceraolo Spurio (4):
  drm/i915: define HAS_MAPPABLE_APERTURE
  drm/i915: do not map aperture if it is not available.
  drm/i915: set num_fence_regs to 0 if there is no aperture
  drm/i915: error capture with no ggtt slot

Matthew Auld (12):
  drm/i915: check for kernel_context
  drm/i915: simplify i915_gem_init_early
  drm/i915: introduce intel_memory_region
  drm/i915/region: support continuous allocations
  drm/i915/region: support volatile objects
  drm/i915: support creating LMEM objects
  drm/i915/selftests: add write-dword test for LMEM
  drm/i915/selftest: extend coverage to include LMEM huge-pages
  drm/i915: treat shmem as a region
  drm/i915: treat stolen as a region
  drm/i915/selftests: check for missing aperture
  HAX drm/i915: add the fake lmem region

Michal Wajdeczko (1):
  drm/i915: Don't try to place HWS in non-existing mappable region
