This patchset converts the remaining drivers to object functions and removes most of the obsolete interfaces. Patches #1 to #16 and #18 to #19 convert DRM drivers to GEM object functions, one by one. Each patch moves existing callbacks from struct drm_driver to an instance of struct drm_gem_object_funcs, and sets these funcs when the GEM object is initialized. The expection is .gem_prime_mmap. There are different ways of how drivers implement the callback, and moving it to GEM object functions requires a closer review for each. Patch #17 fixes virtgpu to use GEM object functions where possible. The driver recently introduced a function for one of the deprecated callbacks. Patch #20 converts xlnx to CMA helper macros. There's no apparent reason why the driver does the GEM setup on it's own. Using CMA helper macros adds GEM object functions implicitly. With most of the GEM and PRIME moved to GEM object functions, related code in struct drm_driver and in the DRM core/helpers is being removed by patch #21. Further testing is welcome. I tested the drivers for which I have HW available. These are gma500, i915, nouveau, radeon and vc4. The console, Weston and Xorg apparently work with the patches applied. v2: * moved code in amdgpu and radeon * made several functions static in various drivers * updated TODO-list item * fix virtgpu Thomas Zimmermann (21): drm/amdgpu: Introduce GEM object functions drm/armada: Introduce GEM object functions drm/etnaviv: Introduce GEM object functions drm/exynos: Introduce GEM object functions drm/gma500: Introduce GEM object functions drm/i915: Introduce GEM object functions drm/mediatek: Introduce GEM object functions drm/msm: Introduce GEM object funcs drm/nouveau: Introduce GEM object functions drm/omapdrm: Introduce GEM object functions drm/pl111: Introduce GEM object functions drm/radeon: Introduce GEM object functions drm/rockchip: Convert to drm_gem_object_funcs drm/tegra: Introduce GEM object functions drm/vc4: Introduce GEM object functions drm/vgem: Introduce GEM object functions drm/virtgpu: Set PRIME export function in struct drm_gem_object_funcs drm/vkms: Introduce GEM object functions drm/xen: Introduce GEM object functions drm/xlnx: Initialize DRM driver instance with CMA helper macro drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver Documentation/gpu/todo.rst | 7 +- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 6 -- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.c | 23 +++-- drivers/gpu/drm/amd/amdgpu/amdgpu_gem.h | 5 -- drivers/gpu/drm/amd/amdgpu/amdgpu_object.c | 1 + drivers/gpu/drm/armada/armada_drv.c | 3 - drivers/gpu/drm/armada/armada_gem.c | 12 ++- drivers/gpu/drm/armada/armada_gem.h | 2 - drivers/gpu/drm/drm_gem.c | 35 ++------ drivers/gpu/drm/drm_gem_cma_helper.c | 6 +- drivers/gpu/drm/drm_prime.c | 17 ++-- drivers/gpu/drm/etnaviv/etnaviv_drv.c | 13 --- drivers/gpu/drm/etnaviv/etnaviv_drv.h | 1 - drivers/gpu/drm/etnaviv/etnaviv_gem.c | 19 ++++- drivers/gpu/drm/exynos/exynos_drm_drv.c | 10 --- drivers/gpu/drm/exynos/exynos_drm_gem.c | 15 ++++ drivers/gpu/drm/gma500/framebuffer.c | 2 + drivers/gpu/drm/gma500/gem.c | 18 +++- drivers/gpu/drm/gma500/gem.h | 3 + drivers/gpu/drm/gma500/psb_drv.c | 9 -- drivers/gpu/drm/gma500/psb_drv.h | 2 - drivers/gpu/drm/i915/gem/i915_gem_object.c | 21 ++++- drivers/gpu/drm/i915/gem/i915_gem_object.h | 3 - drivers/gpu/drm/i915/i915_drv.c | 4 - .../gpu/drm/i915/selftests/mock_gem_device.c | 3 - drivers/gpu/drm/mediatek/mtk_drm_drv.c | 5 -- drivers/gpu/drm/mediatek/mtk_drm_gem.c | 11 +++ drivers/gpu/drm/msm/msm_drv.c | 13 --- drivers/gpu/drm/msm/msm_drv.h | 1 - drivers/gpu/drm/msm/msm_gem.c | 19 ++++- drivers/gpu/drm/nouveau/nouveau_drm.c | 9 -- drivers/gpu/drm/nouveau/nouveau_gem.c | 13 +++ drivers/gpu/drm/nouveau/nouveau_gem.h | 2 + drivers/gpu/drm/nouveau/nouveau_prime.c | 2 + drivers/gpu/drm/omapdrm/omap_drv.c | 9 -- drivers/gpu/drm/omapdrm/omap_gem.c | 18 +++- drivers/gpu/drm/omapdrm/omap_gem.h | 2 - drivers/gpu/drm/pl111/pl111_drv.c | 5 +- drivers/gpu/drm/radeon/radeon_drv.c | 23 +---- drivers/gpu/drm/radeon/radeon_gem.c | 31 ++++++- drivers/gpu/drm/rockchip/rockchip_drm_drv.c | 5 -- drivers/gpu/drm/rockchip/rockchip_drm_gem.c | 10 +++ drivers/gpu/drm/tegra/drm.c | 4 - drivers/gpu/drm/tegra/gem.c | 8 ++ drivers/gpu/drm/vc4/vc4_bo.c | 21 ++++- drivers/gpu/drm/vc4/vc4_drv.c | 12 --- drivers/gpu/drm/vc4/vc4_drv.h | 1 - drivers/gpu/drm/vgem/vgem_drv.c | 21 +++-- drivers/gpu/drm/virtio/virtgpu_drv.c | 1 - drivers/gpu/drm/virtio/virtgpu_object.c | 1 + drivers/gpu/drm/vkms/vkms_drv.c | 8 -- drivers/gpu/drm/vkms/vkms_gem.c | 13 +++ drivers/gpu/drm/xen/xen_drm_front.c | 44 ++++------ drivers/gpu/drm/xen/xen_drm_front.h | 2 + drivers/gpu/drm/xen/xen_drm_front_gem.c | 15 ++++ drivers/gpu/drm/xlnx/zynqmp_dpsub.c | 14 +-- include/drm/drm_drv.h | 85 +------------------ 57 files changed, 319 insertions(+), 349 deletions(-) --- 2.28.0
