Even drivers that do not support PRIME import or export of dma-bufs can now import their own buffer objects. This is required by some userspace, such as wlroots-based compositors, to share buffers among processes. The only driver that does not use the drm_gem_prime_*() helpers is vmwgfx. Leave a comment on the callbacks in struct drm_driver, so that no other driver uses them. Simon Ser implemented the feature for drivers based on GEM VRAM helpers in [1]. This patchset generalizes the code for all drivers that do not otherwise support PRIME. Tested by running sway with gma500 hardware. v2: * documentation and TODO cleanups (Simon, Zack) * small style cleanups [1] https://lore.kernel.org/dri-devel/20230302143502.500661-1-contact@emersion.fr/ Thomas Zimmermann (3): drm: Enable PRIME import/export for all drivers drm: Clear fd/handle callbacks in struct drm_driver drm/prime: Unexport helpers for fd/handle conversion drivers/accel/ivpu/ivpu_drv.c | 2 - drivers/accel/qaic/qaic_drv.c | 1 - drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 4 -- drivers/gpu/drm/armada/armada_drv.c | 2 - drivers/gpu/drm/drm_ioctl.c | 3 +- drivers/gpu/drm/drm_prime.c | 67 +++++++++---------- drivers/gpu/drm/etnaviv/etnaviv_drv.c | 2 - drivers/gpu/drm/exynos/exynos_drm_drv.c | 2 - drivers/gpu/drm/i915/i915_driver.c | 2 - drivers/gpu/drm/lima/lima_drv.c | 2 - drivers/gpu/drm/mediatek/mtk_drm_drv.c | 2 - drivers/gpu/drm/msm/msm_drv.c | 2 - drivers/gpu/drm/nouveau/nouveau_drm.c | 2 - drivers/gpu/drm/omapdrm/omap_drv.c | 2 - drivers/gpu/drm/panfrost/panfrost_drv.c | 2 - drivers/gpu/drm/pl111/pl111_drv.c | 2 - drivers/gpu/drm/qxl/qxl_drv.c | 2 - drivers/gpu/drm/radeon/radeon_drv.c | 2 - drivers/gpu/drm/renesas/rcar-du/rcar_du_drv.c | 2 - drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 2 - drivers/gpu/drm/tegra/drm.c | 2 - drivers/gpu/drm/v3d/v3d_drv.c | 2 - drivers/gpu/drm/virtio/virtgpu_drv.c | 2 - drivers/gpu/drm/xen/xen_drm_front.c | 2 - include/drm/drm_drv.h | 12 +--- include/drm/drm_gem_dma_helper.h | 8 +-- include/drm/drm_gem_shmem_helper.h | 4 +- include/drm/drm_gem_vram_helper.h | 8 +-- include/drm/drm_prime.h | 7 -- 29 files changed, 40 insertions(+), 114 deletions(-) base-commit: 32e260cd0d16cee6f33e747679f168d63ea54bf6 -- 2.41.0
