VBLANK callbacks in struct drm_driver are deprecated in favor of their equivalents in struct drm_crtc_funcs. Convert i915 over. The callback struct drm_driver.get_scanout_position() is deprecated in favor of struct drm_crtc_helper_funcs.get_scanout_position(). i915 doesn't use CRTC helpers. Instead pass i915's implementation of get_scanout_position() to DRM core's drm_crtc_vblank_helpe...

...llbacks 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...

...frastructure. 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. Patches 1 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. Patch 2 changes the VBLANK code to evaluate vblank_disable_immediate in struct drm_device. This simplifies the integration of CRTC VBLANK callbacks in patch 3. If necessary, a future patch could m...
