From: Rob Clark <robdclark@chromium.org> Conversion to DRM GPU VA Manager[1], and adding support for Vulkan Sparse Memory[2] in the form of: 1. A new VM_BIND submitqueue type for executing VM MSM_SUBMIT_BO_OP_MAP/ MAP_NULL/UNMAP commands 2. Extending the SUBMIT ioctl to allow submitting batches of one or more MAP/MAP_NULL/UNMAP commands to a VM_BIND submitqueue The UABI takes a slightly different approach from what other drivers have done, and what would make sense if starting from a clean sheet, ie separate VM_BIND and EXEC ioctls. But since we have to maintain support for the existing SUBMIT ioctl, and because the fence, syncobj, and BO pinning is largely the same between legacy "BO-table" style SUBMIT ioctls, and new- style VM updates submitted to a VM_BIND submitqueue, I chose to go the route of extending the existing `SUBMIT` ioctl rather than adding a new ioctl. I also did not implement support for synchronous VM_BIND commands. Since userspace could just immediately wait for the `SUBMIT` to complete, I don't think we need this extra complexity in the kernel. Synchronous/immediate VM_BIND operations could be implemented with a 2nd VM_BIND submitqueue. The corresponding mesa MR: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/32533 This series can be found in MR form, if you prefer: https://gitlab.freedesktop.org/drm/msm/-/merge_requests/144 Changes in v2: - Dropped Bibek Kumar Patro's arm-smmu patches[3], which have since been merged. - Pre-allocate all the things, and drop HACK patch which disabled shrinker. This includes ensuring that vm_bo objects are allocated up front, pre- allocating VMA objects, and pre-allocating pages used for pgtable updates. The latter utilizes io_pgtable_cfg callbacks for pgtable alloc/free, that were initially added for panthor. - Add back support for BO dumping for devcoredump. - Link to v1 (RFC): https://lore.kernel.org/dri-devel/20241207161651.410556-1-robdclark@gmail.com/T/#t [1] https://www.kernel.org/doc/html/next/gpu/drm-mm.html#drm-gpuvm [2] https://docs.vulkan.org/spec/latest/chapters/sparsemem.html [3] https://patchwork.kernel.org/project/linux-arm-kernel/list/?series=909700 Rob Clark (34): drm/gpuvm: Don't require obj lock in destructor path drm/gpuvm: Remove bogus lock assert drm/gpuvm: Allow VAs to hold soft reference to BOs drm/gpuvm: Add drm_gpuvm_sm_unmap_va() drm/msm: Rename msm_file_private -> msm_context drm/msm: Improve msm_context comments drm/msm: Rename msm_gem_address_space -> msm_gem_vm drm/msm: Remove vram carveout support drm/msm: Collapse vma allocation and initialization drm/msm: Collapse vma close and delete drm/msm: drm_gpuvm conversion drm/msm: Use drm_gpuvm types more drm/msm: Split submit_pin_objects() drm/msm: Lazily create context VM drm/msm: Add opt-in for VM_BIND drm/msm: Mark VM as unusable on faults drm/msm: Extend SUBMIT ioctl for VM_BIND drm/msm: Add VM_BIND submitqueue drm/msm: Add _NO_SHARE flag drm/msm: Split out helper to get iommu prot flags drm/msm: Add mmu support for non-zero offset drm/msm: Add PRR support drm/msm: Rename msm_gem_vma_purge() -> _unmap() drm/msm: Split msm_gem_vma_new() drm/msm: Pre-allocate VMAs drm/msm: Pre-allocate vm_bo objects drm/msm: Pre-allocate pages for pgtable entries drm/msm: Wire up gpuvm ops drm/msm: Wire up drm_gpuvm debugfs drm/msm: Crashdump prep for sparse mappings drm/msm: rd dumping prep for sparse mappings drm/msm: Crashdec support for sparse drm/msm: rd dumping support for sparse drm/msm: Bump UAPI version drivers/gpu/drm/drm_gpuvm.c | 141 ++-- drivers/gpu/drm/msm/Kconfig | 1 + drivers/gpu/drm/msm/adreno/a2xx_gpu.c | 25 +- drivers/gpu/drm/msm/adreno/a2xx_gpummu.c | 5 +- drivers/gpu/drm/msm/adreno/a3xx_gpu.c | 17 +- drivers/gpu/drm/msm/adreno/a4xx_gpu.c | 17 +- drivers/gpu/drm/msm/adreno/a5xx_debugfs.c | 4 +- drivers/gpu/drm/msm/adreno/a5xx_gpu.c | 24 +- drivers/gpu/drm/msm/adreno/a5xx_power.c | 2 +- drivers/gpu/drm/msm/adreno/a5xx_preempt.c | 10 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.c | 32 +- drivers/gpu/drm/msm/adreno/a6xx_gmu.h | 2 +- drivers/gpu/drm/msm/adreno/a6xx_gpu.c | 51 +- drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c | 6 +- drivers/gpu/drm/msm/adreno/a6xx_preempt.c | 10 +- drivers/gpu/drm/msm/adreno/adreno_device.c | 4 - drivers/gpu/drm/msm/adreno/adreno_gpu.c | 84 +- drivers/gpu/drm/msm/adreno/adreno_gpu.h | 23 +- .../drm/msm/disp/dpu1/dpu_encoder_phys_wb.c | 14 +- drivers/gpu/drm/msm/disp/dpu1/dpu_formats.c | 18 +- drivers/gpu/drm/msm/disp/dpu1/dpu_formats.h | 2 +- drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c | 18 +- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.c | 14 +- drivers/gpu/drm/msm/disp/dpu1/dpu_plane.h | 4 +- drivers/gpu/drm/msm/disp/mdp4/mdp4_crtc.c | 6 +- drivers/gpu/drm/msm/disp/mdp4/mdp4_kms.c | 28 +- drivers/gpu/drm/msm/disp/mdp4/mdp4_plane.c | 12 +- drivers/gpu/drm/msm/disp/mdp5/mdp5_crtc.c | 4 +- drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 19 +- drivers/gpu/drm/msm/disp/mdp5/mdp5_plane.c | 12 +- drivers/gpu/drm/msm/dsi/dsi_host.c | 14 +- drivers/gpu/drm/msm/msm_debugfs.c | 20 + drivers/gpu/drm/msm/msm_drv.c | 176 ++--- drivers/gpu/drm/msm/msm_drv.h | 35 +- drivers/gpu/drm/msm/msm_fb.c | 18 +- drivers/gpu/drm/msm/msm_fbdev.c | 2 +- drivers/gpu/drm/msm/msm_gem.c | 437 +++++----- drivers/gpu/drm/msm/msm_gem.h | 226 ++++-- drivers/gpu/drm/msm/msm_gem_prime.c | 15 + drivers/gpu/drm/msm/msm_gem_submit.c | 234 +++++- drivers/gpu/drm/msm/msm_gem_vma.c | 748 ++++++++++++++++-- drivers/gpu/drm/msm/msm_gpu.c | 146 ++-- drivers/gpu/drm/msm/msm_gpu.h | 132 +++- drivers/gpu/drm/msm/msm_iommu.c | 285 ++++++- drivers/gpu/drm/msm/msm_kms.c | 18 +- drivers/gpu/drm/msm/msm_kms.h | 2 +- drivers/gpu/drm/msm/msm_mmu.h | 38 +- drivers/gpu/drm/msm/msm_rd.c | 62 +- drivers/gpu/drm/msm/msm_ringbuffer.c | 4 +- drivers/gpu/drm/msm/msm_submitqueue.c | 86 +- include/drm/drm_gpuvm.h | 14 +- include/uapi/drm/msm_drm.h | 98 ++- 52 files changed, 2359 insertions(+), 1060 deletions(-)
