drm/gem-vram: Un-export pin helpers

2025-05-30T07:47:28Z

There are no external callers of the gem-vram pin helpers. Hence unexport them. Signed-off-by: Thomas Zimmermann Reviewed-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20250526132634.531789-4-tzimmermann@suse.de

drm/vram-helper: Fix 'multi-line' kernel-doc comments

2024-01-30T20:03:01Z

Reformat lines in kernel-doc comments, which make use of the backslash at the end to suggest it is a multi-line comment. kernel-doc is able to process e.g. the short description of a function properly, even if it is across two lines. No functional change.

drm: Clear fd/handle callbacks in struct drm_driver

Clear all assignments of struct drm_driver's fd/handle callbacks to drm_gem_prime_fd_to_handle() and drm_gem_prime_handle_to_fd(). These functions are called by default.

drm/vram-helper: turn on PRIME import/export

2023-04-03T12:31:24Z

We don't populate drm_driver.gem_prime_import_sg_table so only DMA-BUFs exported from our own device can be imported. We don't populate drm_gem_object_funcs.get_sg_table so DMA-BUFs cannot be imported into another device.

dma-buf-map: Rename to iosys-map

2022-02-08T00:35:35Z

Rename struct dma_buf_map to struct iosys_map and corresponding APIs. Over time dma-buf-map grew up to more functionality than the one used by dma-buf: in fact it's just a shim layer to abstract system memory, that can be accessed via regular load and store, from IO memory that needs to be acessed via arch helpers. The idea is to extend this API so it can fulfill other needs, internal to a single driver. Example: in the i915 driver it's desired to share the implementation for integrated graphics, which uses mostly system memory, with discrete graphics, which may need to access IO memory. The conversion was mostly done with the following semantic patch: @r1@ @@ - struct dma_buf_map + struct iosys_map @r2@ @@ ( - DMA_BUF_MAP_INIT_VADDR + IOSYS_MAP_INIT_VADDR | - dma_buf_map_set_vaddr + iosys_map_set_vaddr | - dma_buf_map_set_vaddr_iomem + iosys_map_set_vaddr_iomem | - dma_buf_map_is_equal + iosys_map_is_equal | - dma_buf_map_is_null + iosys_map_is_null | - dma_buf_map_is_set + iosys_map_is_set | - dma_buf_map_clear + iosys_map_clear | - dma_buf_map_memcpy_to + iosys_map_memcpy_to | - dma_buf_map_incr + iosys_map_incr ) @@ @@ - #include + #include Then some files had their includes adjusted and some comments were update to remove mentions to dma-buf-map. Since this is not specific to dma-buf anymore, move the documentation to the "Bus-Independent Device Accesses" section. v2: - Squash patches v3: - Fix wrong removal of dma-buf.h from MAINTAINERS - Move documentation from dma-buf.rst to device-io.rst v4: - Change documentation title and level Signed-off-by: Lucas De Marchi Acked-by: Christian König Acked-by: Sumit Semwal Acked-by: Thomas Zimmermann Link: https://patchwork.freedesktop.org/patch/msgid/20220204170541.829227-1-lucas.demarchi@intel.com
