2021-10-25dma-buf: move dma-buf symbols into the DMA_BUF module namespaceGreg Kroah-Hartman
In order to better track where in the kernel the dma-buf code is used, put the symbols in the namespace DMA_BUF and modify all users of the symbols to properly import the namespace to not break the build at the same time. Now the output of modinfo shows the use of these symbols, making it easier to watch for users over time: $ modinfo drivers/misc/fastrpc.ko | grep import import_ns: DMA_BUF Cc: "Pan, Xinhui" <Xinhui.Pan@amd.com> Cc: David Airlie <airlied@linux.ie> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Maxime Ripard <mripard@kernel.org> Cc: Thomas Zimmermann <tzimmermann@suse.de> Cc: Mauro Carvalho Chehab <mchehab@kernel.org> Cc: dri-devel@lists.freedesktop.org Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Christian König <christian.koenig@amd.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Sumit Semwal <sumit.semwal@linaro.org> Acked-by: Alex Deucher <alexander.deucher@amd.com> Link: https://lore.kernel.org/r/20211010124628.17691-1-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-10-13drm/amdkfd: unregistered svm range not overlap with TTM rangePhilip Yang
When creating unregistered new svm range to recover retry fault, avoid new svm range to overlap with ranges or userptr ranges managed by TTM, otherwise svm migration will trigger TTM or userptr eviction, to evict user queues unexpectedly. Change helper amdgpu_ttm_tt_affect_userptr to return userptr which is inside the range. Add helper svm_range_check_vm_userptr to scan all userptr of the vm, and return overlap userptr bo start, last.

2021-07-01drm/amdgpu: Set ttm caching flags during bo allocationOak Zeng
The ttm caching flags (ttm_cached, ttm_write_combined etc) are used to determine a buffer object's mapping attributes in both CPU page table and GPU page table (when that buffer is also accessed by GPU). Currently the ttm caching flags are set in function amdgpu_ttm_io_mem_reserve which is called during DRM_AMDGPU_GEM_MMAP ioctl. This has a problem since the GPU mapping of the buffer object (ioctl DRM_AMDGPU_GEM_VA) can happen earlier than the mmap time, thus the GPU page table update code can't pick up the right ttm caching flags to decide the right GPU page table attributes. This patch moves the ttm caching flags setting to function amdgpu_vram_mgr_new - this function is called during the first step of a buffer object create (eg, DRM_AMDGPU_GEM_CREATE) so the later both CPU and GPU mapping function calls will pick up this flag for CPU/GPU page table set up. v2: rebase (Alex) Signed-off-by: Oak Zeng <Oak.Zeng@amd.com> Suggested-by: Christian Koenig <Christian.Koenig@amd.com> Reviewed-by: Christian Koenig <Christian.Koenig@amd.com> Reviewed-by: Feifei Xu <Feifei.Xu@amd.com> Tested-by: Po Huang <Po.Huang@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

2021-06-07drm/ttm, drm/amdgpu: Allow the driver some control over swappingThomas Hellström
We are calling the eviction_valuable driver callback at eviction time to determine whether we actually can evict a buffer object. The upcoming i915 TTM backend needs the same functionality for swapout, and that might actually be beneficial to other drivers as well. Add an eviction_valuable call also in the swapout path. Try to keep the current behaviour for all drivers by returning true if the buffer object is already in the TTM_PL_SYSTEM placement. We change behaviour for the case where a buffer object is in a TT backed placement when swapped out, in which case the drivers normal eviction_valuable path is run.

2021-05-26drm/amdgpu: Implement mmap as GEM object functionThomas Zimmermann
Moving the driver-specific mmap code into a GEM object function allows for using DRM helpers for various mmap callbacks. This change resolves several inconsistencies between regular mmap and prime-based mmap. The vm_ops field in vma is now set for all mmap'ed areas. Previously it way only set for regular mmap calls, prime-based mmap used TTM's default vm_ops. The function amdgpu_verify_access() is no longer being called and therefore removed by this patch. As a side effect, amdgpu_ttm_vm_ops and amdgpu_ttm_fault() are now implemented in amdgpu's GEM code. v4: * rebased v3: * rename mmap function to amdgpu_gem_object_mmap() (Christian) * remove unnecessary checks from mmap (Christian) v2: * rename amdgpu_ttm_vm_ops and amdgpu_ttm_fault() to amdgpu_gem_vm_ops and amdgpu_gem_fault() (Christian) * the check for kfd_bo has meanwhile been removed Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Christian König <christian.koenig@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210525151055.8174-3-tzimmermann@suse.de

2021-05-21drm/amdgpu: Add new placement for preemptible SG BOsFelix Kuehling
SG BOs such as dmabuf imports and userptr BOs do not consume system resources directly. Instead they point to resources owned elsewhere. They typically get evicted by DMABuf move notifiers of MMU notifiers. If those notifiers don't need to wait for hardware fences (i.e. the SG BOs are used in a preemptible context), then we don't need to limit them to the GTT size and we don't need TTM to evict them. Create a new placement for such preemptible SG BOs that does not impose artificial size limits and TTM evictions.

2021-05-19drm/amdgpu: Move dmabuf attach/detach to backend_(un)bindFelix Kuehling
The dmabuf attachment should be updated by moving the SG BO to DOMAIN_CPU and back to DOMAIN_GTT. This does not necessarily invoke the populate/unpopulate callbacks. Do this in backend_bind/unbind instead.

2021-05-19drm/amdgpu: Fix GPU TLB update error when PAGE_SIZE > AMDGPU_PAGE_SIZEYi Li
When PAGE_SIZE is larger than AMDGPU_PAGE_SIZE, the number of GPU TLB entries which need to update in amdgpu_map_buffer() should be multiplied by AMDGPU_GPU_PAGES_IN_CPU_PAGE (PAGE_SIZE / AMDGPU_PAGE_SIZE).
