Almost all TTM-based drivers use the same values for the mmap-able range of BO addresses. Each driver therefore duplicates the DRM_FILE_PAGE_OFFSET constant. OTOH, the mmap range's size is not configurable by drivers. This patch set replaces driver-specific configuration with a single setup. All code is located within TTM. TTM and GEM share the same range for mmap-able BOs. Thomas Zimmermann (5): staging/vboxvideo: Use same BO mmap offset as other drivers drm/ttm: Define a single DRM_FILE_PAGE_OFFSET constant drm/ttm: Remove file_page_offset parameter from ttm_bo_device_init() drm/ttm: Quick-test mmap offset in ttm_bo_mmap() drm: Use the same mmap-range offset and size for GEM and TTM drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 12 ++---------- drivers/gpu/drm/ast/ast_drv.h | 2 -- drivers/gpu/drm/ast/ast_ttm.c | 10 ++-------- drivers/gpu/drm/bochs/bochs.h | 2 -- drivers/gpu/drm/bochs/bochs_mm.c | 10 ++-------- drivers/gpu/drm/cirrus/cirrus_drv.h | 1 - drivers/gpu/drm/cirrus/cirrus_ttm.c | 10 ++-------- drivers/gpu/drm/drm_gem.c | 17 ----------------- drivers/gpu/drm/hisilicon/hibmc/hibmc_ttm.c | 12 ++---------- drivers/gpu/drm/mgag200/mgag200_drv.h | 1 - drivers/gpu/drm/mgag200/mgag200_ttm.c | 10 ++-------- drivers/gpu/drm/nouveau/nouveau_drv.h | 2 -- drivers/gpu/drm/nouveau/nouveau_ttm.c | 4 ---- drivers/gpu/drm/qxl/qxl_drv.h | 3 --- drivers/gpu/drm/qxl/qxl_ttm.c | 11 +++-------- drivers/gpu/drm/radeon/radeon_ttm.c | 13 ++----------- drivers/gpu/drm/ttm/ttm_bo.c | 6 +++--- drivers/gpu/drm/ttm/ttm_bo_vm.c | 3 +++ drivers/gpu/drm/virtio/virtgpu_ttm.c | 4 +--- drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 1 - drivers/gpu/drm/vmwgfx/vmwgfx_drv.h | 1 - drivers/gpu/drm/vmwgfx/vmwgfx_ttm_glue.c | 11 ++--------- drivers/staging/vboxvideo/vbox_drv.h | 2 -- drivers/staging/vboxvideo/vbox_ttm.c | 12 +++--------- include/drm/drm_vma_manager.h | 12 ++++++++++++ include/drm/ttm/ttm_bo_driver.h | 2 +- 26 files changed, 42 insertions(+), 132 deletions(-) -- 2.20.1 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
