In preparation for upcoming devices with device local memory, introduce the
concept of different memory regions, and a simple buddy allocator to manage
them.

At the end of the series are a couple of HAX patches which introduce a fake
local memory region for testing purposes. Currently smoke tested on a Skull
Canyon device.

Abdiel Janulgue (13):
drm/i915: Add memory region information to device_info
drm/i915/lmem: add helper to get CPU visible pfn
drm/i915/lmem: support kernel mapping
drm/i915: Split out GTT fault handler to make it generic
drm/i915: Set correct vmf source pages for gem objects
drm/i915: Introduce DRM_I915_GEM_MMAP_OFFSET
drm/i915: cpu-map based dumb buffers
drm/i915: Add fill_pages handler for dma_buf imported objects
UPSTREAM: drm/i915/query: Split out query item checks
drm/i915/query: Expose memory regions through the query uAPI
drm/i915: Introduce GEM_OBJECT_SETPARAM with I915_PARAM_MEMORY_REGION
drm/i915: enumerate and init each supported region
drm/i915: setup io-mapping for LMEM

Daniele Ceraolo Spurio (5):
drm/i915: define HAS_MAPPABLE_APERTURE
drm/i915: do not map aperture if it is not available.
drm/i915: expose missing map_gtt support to users
drm/i915: set num_fence_regs to 0 if there is no aperture
drm/i915: error capture with no ggtt slot

Matthew Auld (23):
drm/i915: support 1G pages for the 48b PPGTT
drm/i915: enable platform support for 1G pages
drm/i915: buddy allocator
drm/i915: introduce intel_memory_region
drm/i915/region: support basic eviction
drm/i915/region: support continuous allocations
drm/i915/region: support volatile objects
drm/i915: support creating LMEM objects
drm/i915/selftests: exercise writes to LMEM
drm/i915/selftests: exercise huge-pages for LMEM
drm/i915: support object clearing via blitter engine
drm/i915: introduce kernel blitter_context
drm/i915: support copying objects via blitter engine
drm/i915: support basic object migration
drm/i915/lmem: support CPU relocations
drm/i915: add vfunc for pread
drm/i915/lmem: support pread
drm/i915/lmem: support pwrite
drm/i915/lmem: include debugfs metrics
drm/i915: treat shmem as a region
drm/i915: treat stolen as a region
HAX drm/i915: add the fake lmem region
HAX drm/i915/lmem: default userspace allocations to LMEM

drm/i915: Don't try to place HWS in non-existing mappable region
