[Nouveau] [PATCH v3 00/22] Convert all remaining drivers to GEM object functions
The GEM and PRIME related callbacks in struct drm_driver are deprecated in favor of GEM object functions in struct drm_gem_object_funcs. This patchset converts the remaining drivers to object functions and removes most of the obsolete interfaces. Version 3 of this patchset mostly fixes drm_gem_prime_handle_to_fd and updates i.MX's dcss driver. The driver was missing from earlier versions and still needs review. Patches #1 to #6, #8 to #17 and #19 to #20 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 #18 fixes virtgpu to use GEM object functions where possible. The driver recently introduced a function for one of the deprecated callbacks. Patches #7 and #20 convert i.MX's dcss and xlnx to CMA helper macros. There's no apparent reason why the drivers do the GEM setup on their'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 #22. 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. v3: * restore default call to drm_gem_prime_export() in drm_gem_prime_handle_to_fd() * return -ENOSYS if get_sg_table is not set * drop all checks for obj->funcs * clean up TODO list and documentation v2: * moved code in amdgpu and radeon * made several functions static in various drivers * updated TODO-list item * fix virtgpu Thomas Zimmermann (22): 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/imx/dcss: Initialize DRM driver instance with CMA helper macro 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/drm-mm.rst | 4 +- Documentation/gpu/todo.rst | 9 +- 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/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 | 53 ++++-------- drivers/gpu/drm/drm_gem_cma_helper.c | 8 +- drivers/gpu/drm/drm_prime.c | 14 +-- 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/imx/dcss/dcss-kms.c | 14 +-- 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 | 12 ++- 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 +------------------ include/drm/drm_gem.h | 2 +- 59 files changed, 333 insertions(+), 375 deletions(-) -- 2.28.0

[Nouveau] [PATCH v3 01/22] drm/amdgpu: Introduce GEM object functions
GEM object functions deprecate several similar callback interfaces in
struct drm_driver. This patch replaces the per-driver callbacks with
per-instance callbacks in amdgpu. The only exception is gem_prime_mmap,
which is non-trivial to convert.
v3:
* remove amdgpu_object.c from patch (Christian)
v2:
* move object-function instance to amdgpu_gem.c (Christian)
* set callbacks in amdgpu_gem_object_create() (Christian)

[Nouveau] [PATCH v3 07/22] drm/imx/dcss: Initialize DRM driver instance with CMA helper macro
The i.MX DCSS driver uses CMA helpers with default callback functions.
Initialize the driver structure with the rsp CMA helper macro. The
driver is being converted to use GEM object functions as part of
this change.
Two callbacks, .gem_prime_export and .gem_prime_import, were initialized
to their default implementations, so they are just kept empty now.

[Nouveau] [PATCH v3 21/22] drm/xlnx: Initialize DRM driver instance with CMA helper macro
The xlnx driver uses CMA helpers with default callback functions.
Initialize the driver structure with the rsp CMA helper macro. The
driver is being converted to use GEM object functions as part of
this change.
Two callbacks, .dumb_destroy and .gem_prime_import, were initialized
to their default implementations, so they are just kept empty now.
v2:
* initialize with DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE (Laurent)

[Nouveau] [PATCH v3 22/22] drm: Remove obsolete GEM and PRIME callbacks from struct drm_driver
Several GEM and PRIME callbacks have been deprecated in favor of
per-instance GEM object functions. Remove the callbacks as they are
now unused. The only exception is .gem_prime_mmap, which is still
in use by several drivers.
What is also gone is gem_vm_ops in struct drm_driver. All drivers now
use struct drm_gem_object_funcs.vm_ops instead.
While at it, the patch also improves error handling around calls
to .free and .get_sg_table callbacks.
v3:
* restore default call to drm_gem_prime_export() in
drm_gem_prime_handle_to_fd()
* return -ENOSYS if get_sg_table is not set
* drop all checks for obj->funcs
* clean up TODO list and documentation
v2:
* update related TODO item (Sam)
