[PATCH] drm/i915/selftests: Increase timeout for live_parallel_switch
by Matthew Auld 22 Jun '22

22 Jun '22

From: Akeem G Abodunrin <akeem.g.abodunrin(a)intel.com> With GuC submission, it takes a little bit longer switching contexts among all available engines simultaneously, when running live_parallel_switch subtest. Increase the timeout.

[PATCH v3 0/3] Improve vfio-pci primary GPU assignment behavior
by Thomas Zimmermann 22 Jun '22

22 Jun '22

(I'm taking over this patchset from Alex, [1] as we agreed that it should go through the drm-misc tree.) When assigning a primary graphics device to VM through vfio-pci device assignment, users often prevent binding of the native PCI graphics driver to avoid device initialization conflicts, however firmware console drivers may still be attached to the device which can often be cumbersome to manually unbind or exclude via cmdline options. This series proposes to move the DRM aperture helpers … [View More]

[PATCH 00/64] drm/vc4: Fix hotplug for vc4
by Maxime Ripard 22 Jun '22

22 Jun '22

Hi, Here is a series that address multiple issues when trying to unbind/rebind vc4-related devices to their drivers. Most of these issues involve either use-after-free, improper resource liberation or similar. It has been tested on the Pi3 and Pi4, with X and glxgears running and KASAN enabled to properly validate our memory accesses. Pi3 isn't functional after a rebind though, with vblank timeouts occuring. I'm not quite sure why at this point, but at least the kernel doesn't completely … [View More]crash now.

[PATCH v8 00/10] drm/i915: ttm for stolen
by Robert Beckett 22 Jun '22

22 Jun '22

This series refactors i915's stolen memory region to use ttm. v2: handle disabled stolen similar to legacy version. relying on ttm to fail allocs works fine, but is dmesg noisy and causes testing dmesg warning regressions. v3: rebase to latest drm-tip. fix v2 code refactor which could leave a buffer pinned. locally passes fftl again now. v4: - Allow memory regions creators to do allocation. Allows stolen region to track it's own reservations. - Pre-reserve first page of stolen mem (… [View More]add back WaSkipStolenMemoryFirstPage:bdw+) - Improve commit descritpion for "drm/i915: sanitize mem_flags for stolen buffers" - replace i915_gem_object_pin_pages_unlocked() call with manual locking and pinning. this avoids ww ctx class reuse during context creation -> ring vma obj alloc. v5: - detect both types of stolen as stolen buffers in "drm/i915: sanitize mem_flags for stolen buffers" - in stolen_object_init limit page size to mem region minimum. The range allocator expects the page_size to define the alignment v6: - Share first 4 patches from ttm for internal series as generic i915 ttm fixes - Drop patch 4 from v5. We don't need separate object ops just to satisfy test interfaces. The tests have now been fixed via checking whether the memory region is private to decide whether to mmap - Add new buffer pin alloc flag to allow creation of buffers in their final ttm placement instead of deferring until get_pages. This fixes legacy fallback paths for buffer allocations during stolen memory pressure. v7: - fix mock_region_get_pages() to correctly handle I915_BO_INVALID_OFFSET v8: - Reserve I915_GEM_STOLEN_BIAS area from stolen Robert Beckett (10): drm/i915/ttm: dont trample cache_level overrides during ttm move drm/i915: limit ttm to dma32 for i965G[M] drm/i915/ttm: only trust snooping for dgfx when deciding default cache_level drm/i915/gem: selftest should not attempt mmap of private regions drm/i915: instantiate ttm ranger manager for stolen memory drm/i915: sanitize mem_flags for stolen buffers drm/i915: ttm move/clear logic fix drm/i915: allow memory region creators to alloc and free the region drm/i915/ttm: add buffer pin on alloc flag drm/i915: stolen memory use ttm backend drivers/gpu/drm/i915/display/intel_fbc.c | 78 ++-- drivers/gpu/drm/i915/gem/i915_gem_object.c | 1 + .../gpu/drm/i915/gem/i915_gem_object_types.h | 16 +- drivers/gpu/drm/i915/gem/i915_gem_stolen.c | 441 +++++++----------- drivers/gpu/drm/i915/gem/i915_gem_stolen.h | 21 +- drivers/gpu/drm/i915/gem/i915_gem_ttm.c | 29 +- drivers/gpu/drm/i915/gem/i915_gem_ttm.h | 7 + drivers/gpu/drm/i915/gem/i915_gem_ttm_move.c | 47 +- .../drm/i915/gem/selftests/i915_gem_mman.c | 3 + drivers/gpu/drm/i915/gt/intel_rc6.c | 4 +- drivers/gpu/drm/i915/gt/selftest_reset.c | 16 +- drivers/gpu/drm/i915/i915_debugfs.c | 7 +- drivers/gpu/drm/i915/i915_drv.h | 5 - drivers/gpu/drm/i915/intel_memory_region.c | 16 +- drivers/gpu/drm/i915/intel_memory_region.h | 2 + drivers/gpu/drm/i915/intel_region_ttm.c | 80 +++- drivers/gpu/drm/i915/intel_region_ttm.h | 8 +- drivers/gpu/drm/i915/selftests/mock_region.c | 12 +- 18 files changed, 424 insertions(+), 369 deletions(-) -- 2.25.1 [View Less]
