It supersedes the 64K patches from https://patchwork.freedesktop.org/series/95686/#rev4 Changes since that series: - set min alignment for DG2 to 2MB in i915_address_space_init - replace coloring with simpler 2MB VA alignment for lmem buffers - enforce alignment to 2MB for lmem objects on DG2 in i915_vma_insert - expand vma reservation to round up to 2MB on DG2 in i915_vma_insert - add alignment test v2: rebase and fix for async vma that landed v3: * fix uapi doc typos * add needs_compact_pt flag patch * cleanup vma expansion to use vm->min_alignment instead of hard coding Matthew Auld (3): drm/i915: enforce min GTT alignment for discrete cards drm/i915: support 64K GTT pages for discrete cards drm/i915/uapi: document behaviour for DG2 64K support Ramalingam C (1): drm/i915: add needs_compact_pt flag Robert Beckett (1): drm/i915: add gtt misalignment test .../gpu/drm/i915/gem/selftests/huge_pages.c | 60 +++++ .../i915/gem/selftests/i915_gem_client_blt.c | 23 +- drivers/gpu/drm/i915/gt/gen8_ppgtt.c | 108 ++++++++- drivers/gpu/drm/i915/gt/intel_gtt.c | 12 + drivers/gpu/drm/i915/gt/intel_gtt.h | 18 ++ drivers/gpu/drm/i915/gt/intel_ppgtt.c | 1 + drivers/gpu/drm/i915/i915_drv.h | 10 +- drivers/gpu/drm/i915/i915_pci.c | 2 + drivers/gpu/drm/i915/i915_vma.c | 9 + drivers/gpu/drm/i915/intel_device_info.h | 1 + drivers/gpu/drm/i915/selftests/i915_gem_gtt.c | 226 +++++++++++++++--- include/uapi/drm/i915_drm.h | 44 +++- 12 files changed, 462 insertions(+), 52 deletions(-)
