VBLANK handlers in struct drm_driver are deprecated. Only legacy, non-KMS drivers are supposed to used them. DRM drivers with kernel modesetting are supposed to use VBLANK callbacks of the CRTC infrastructure. This patchset converts all DRM drivers to CRTC VBLANK callbacks and cleans up struct drm_driver. The remaining VBLANK callbacks in struct drm_driver are only used by legacy drivers. Patch 1 removes an additional setup step of vblank_disable_immediate in struct drm_device. This simplifies the integration of CRTC VBLANK callbacks in patch 3. If necessary, a future patch could move vblank_disable_immedate to struct drm_crtc, so that high-precision VBLANKs could be enabled on a per-CRTC basis. Patches 2 and 3 prepare the DRM infrastructure. These patches add get_scanout_position() to struct drm_crtc_helper_funcs, get_vblank_timestamp() to struct drm_crtc_funcs, and add helpers for the new interfaces. Patches 4 to 20 convert drivers over. In patch 21, all VBLANK callbacks are removed from struct drm_driver, except for get_vblank_counter(), enable_vblank(), and disable_vblank(). These interfaces are moved to the legacy section at the end of the structure. Old helper code is now unused and being removed as well. Finally, patch 22 removes an older version of get_scanout_position() from the VBLANK interface. To cover all affected drivers, I build the patchset in x86, x86-64, arm and aarch64. I smoke-tested amdgpu, gma500, i915, radeon and vc4 on respective hardware. v4: * fixed warnings and improved code readability (Ville, Jani) v3: * refactor drm_calc_vbltimestamp_from_scanout_pos to share code with new helper (Villa, Jani) * do more checks for crtc != NULL to cover non-KMS drivers (Ville) * add function typedefs for readability (Ville) v2: * reorder patches so the i915 can be converted without duplicating helper code. * merged cleanup patches * changed VBLANK function signatures in amdgpu (Alex) Thomas Zimmermann (22): drm: Remove internal setup of struct drm_device.vblank_disable_immediate drm: Add get_scanout_position() to struct drm_crtc_helper_funcs drm: Add get_vblank_timestamp() to struct drm_crtc_funcs drm/amdgpu: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/amdgpu: Convert to CRTC VBLANK callbacks drm/gma500: Convert to CRTC VBLANK callbacks drm/i915: Convert to CRTC VBLANK callbacks drm/nouveau: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/nouveau: Convert to CRTC VBLANK callbacks drm/radeon: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/radeon: Convert to CRTC VBLANK callbacks drm/msm: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/msm: Convert to CRTC VBLANK callbacks drm/stm: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/stm: Convert to CRTC VBLANK callbacks drm/sti: Convert to CRTC VBLANK callbacks drm/vc4: Convert to struct drm_crtc_helper_funcs.get_scanout_position() drm/vc4: Convert to CRTC VBLANK callbacks drm/vkms: Convert to CRTC VBLANK callbacks drm/vmwgfx: Convert to CRTC VBLANK callbacks drm: Clean-up VBLANK-related callbacks in struct drm_driver drm: Remove legacy version of get_scanout_position() drivers/gpu/drm/amd/amdgpu/amdgpu.h | 6 +- drivers/gpu/drm/amd/amdgpu/amdgpu_display.c | 16 +- drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c | 15 -- drivers/gpu/drm/amd/amdgpu/amdgpu_kms.c | 21 ++- drivers/gpu/drm/amd/amdgpu/amdgpu_mode.h | 5 + drivers/gpu/drm/amd/amdgpu/dce_v10_0.c | 5 + drivers/gpu/drm/amd/amdgpu/dce_v11_0.c | 5 + drivers/gpu/drm/amd/amdgpu/dce_v6_0.c | 5 + drivers/gpu/drm/amd/amdgpu/dce_v8_0.c | 5 + drivers/gpu/drm/amd/amdgpu/dce_virtual.c | 5 + .../gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.c | 13 +- drivers/gpu/drm/drm_vblank.c | 146 +++++++++------- drivers/gpu/drm/gma500/cdv_intel_display.c | 3 + drivers/gpu/drm/gma500/psb_drv.c | 4 - drivers/gpu/drm/gma500/psb_drv.h | 6 +- drivers/gpu/drm/gma500/psb_intel_display.c | 3 + drivers/gpu/drm/gma500/psb_irq.c | 12 +- drivers/gpu/drm/gma500/psb_irq.h | 7 +- drivers/gpu/drm/i915/display/intel_display.c | 7 + drivers/gpu/drm/i915/i915_drv.c | 3 - drivers/gpu/drm/i915/i915_irq.c | 20 ++- drivers/gpu/drm/i915/i915_irq.h | 6 +- drivers/gpu/drm/msm/disp/dpu1/dpu_crtc.c | 2 + drivers/gpu/drm/msm/disp/mdp4/mdp4_crtc.c | 2 + drivers/gpu/drm/msm/disp/mdp5/mdp5_crtc.c | 82 +++++++++ drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c | 95 ----------- drivers/gpu/drm/msm/msm_drv.c | 10 +- drivers/gpu/drm/msm/msm_drv.h | 3 + drivers/gpu/drm/nouveau/dispnv04/crtc.c | 4 + drivers/gpu/drm/nouveau/dispnv50/head.c | 5 + drivers/gpu/drm/nouveau/nouveau_display.c | 28 +--- drivers/gpu/drm/nouveau/nouveau_display.h | 11 +- drivers/gpu/drm/nouveau/nouveau_drm.c | 5 - drivers/gpu/drm/radeon/atombios_crtc.c | 1 + drivers/gpu/drm/radeon/radeon_display.c | 25 ++- drivers/gpu/drm/radeon/radeon_drv.c | 18 -- drivers/gpu/drm/radeon/radeon_kms.c | 29 ++-- drivers/gpu/drm/radeon/radeon_legacy_crtc.c | 3 +- drivers/gpu/drm/radeon/radeon_mode.h | 6 + drivers/gpu/drm/sti/sti_crtc.c | 11 +- drivers/gpu/drm/sti/sti_crtc.h | 2 - drivers/gpu/drm/sti/sti_drv.c | 4 - drivers/gpu/drm/stm/drv.c | 2 - drivers/gpu/drm/stm/ltdc.c | 66 ++++---- drivers/gpu/drm/stm/ltdc.h | 5 - drivers/gpu/drm/vc4/vc4_crtc.c | 13 +- drivers/gpu/drm/vc4/vc4_drv.c | 3 - drivers/gpu/drm/vc4/vc4_drv.h | 4 - drivers/gpu/drm/vkms/vkms_crtc.c | 9 +- drivers/gpu/drm/vkms/vkms_drv.c | 1 - drivers/gpu/drm/vkms/vkms_drv.h | 4 - drivers/gpu/drm/vmwgfx/vmwgfx_drv.c | 3 - drivers/gpu/drm/vmwgfx/vmwgfx_drv.h | 6 +- drivers/gpu/drm/vmwgfx/vmwgfx_kms.c | 6 +- drivers/gpu/drm/vmwgfx/vmwgfx_ldu.c | 3 + drivers/gpu/drm/vmwgfx/vmwgfx_scrn.c | 3 + drivers/gpu/drm/vmwgfx/vmwgfx_stdu.c | 3 + include/drm/drm_crtc.h | 46 +++++- include/drm/drm_drv.h | 156 +----------------- include/drm/drm_modeset_helper_vtables.h | 47 ++++++ include/drm/drm_vblank.h | 35 +++- 61 files changed, 559 insertions(+), 520 deletions(-) -- 2.24.1 _______________________________________________ amd-gfx mailing list amd-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/amd-gfx
