Only remaining use was in amdgpu, and trivial to convert over to drm_crtc_vblank_* variants. Cc: Alex Deucher <alexander.deucher@amd.com> Cc: Christian König <christian.koenig@amd.com> Reviewed-by:

No one outside of drm_irq.c should ever need this. The correct way to implement get_vblank_count for hw lacking a vblank counter is drm_vblank_no_hw_counter. Fix this up in mtk, which is the only offender left over. Cc: CK Hu <ck.hu@mediatek.com> Cc: Philipp Zabel <p.zabel@pengutronix.de> Acked-by:

Now that all drivers are switched over to drm_crtc_vblank_on/off we can relegate pre/post_modeset to the purely drm_irq.c internal role of supporting old ums userspace. As usual switch to the drm_legacy_ prefix to make it clear this is for old drivers only. v2: Rebase on top of Thierry's s/int crtc/unsigned int pipe/ changes.

With atomic nv50+ is already converted over to them, but the old display code is still using it. Found in a 2 year old patch I have lying around to un-export these old helpers! v2: Drop the hand-rolled versions from resume/suspend code. Now that crtc callbacks do this, we don't need a special case for s/r anymore. v3: Remove unused variables. v4: Don't remove drm_crtc_vblank_off from suspend paths, non-atomic nouveau still needs that. But still switch to drm_crtc_vblank_off since drm_vblank_off will disappear. Cc: Mario Kleiner <mario.kleiner.de@gmail.com> Cc: Ben Skeggs <bskeggs@redhat.com> Reviewed-by:

And also put the overview section into the KMS Properties part of the docs, instead of randomly-placed within the helpers - this is part of the uabi. With this patch I think drm_crtc.[hc] is cleaned up and entirely documented. Reviewed-by:

And shuffle the kernel-doc structure a bit since drm_crtc.[hc] now only contains CRTC-related functions and structures. v2: - rebase onto drm-misc - don't forget to move drm_mode_config_cleanup. - move 2 internal decls under the right heading (Chris) Reviewed-by:

This reverts commit 6dffd431. Adding new mode flags willy nilly breaks existing userspace. We need to coordinate this better, potentially with a new client cap that only exposes the aspect ratio flags when userspace is prepared for them (similar to what we do with stereo 3D modes). This also broke things so that we would always send out VIC==0 in the AVI infoframe unless the user specified an aspect ratio via the mode flags. And the automagic RGB full vs. limited range handling was similartly broken as the user mode would never match any CEA mode.

Daniel Vetter authored
I want to move dumb buffer documentation into the right vfuncs, and for that I first need to be able to pull that into kerneldoc without having to clean up all of drmP.h. Also, header-splitting is nice. While at it shuffle all the function declarations for drm_drv.c into the right spots, and drop the kerneldoc for drm_minor_acquire/release since it's only used internally. v2: Keep all existing copyright notices (Chris).

kbuild spotted this error, with drm/msm patches that add a new modeset-lock in the driver and driver built as a module: ERROR: "crtc_ww_class" [drivers/gpu/drm/msm/msm.ko] undefined! Really the only reason for crtc_ww_class not being internal to drm_modeset_lock.c is that drm_modeset_lock_init() was static-inline (for no particularly good reason). Fix that, and move crtc_ww_class into drm_modeset_lock.c. Signed-off-by:

Add new drm_fb_cma_prepare_fb() helper function extracted from the imx-drm driver. This function checks if the plane has DMABUF attached to it, extracts the exclusive fence from it and attaches it to the plane state for the atomic helper to wait on it. Signed-off-by:

This refactoring leads to real functional changes in the driver. Now the struct psbfb_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, and the struct psbfb_roll_ops implements one additional member: .fb_setcmap = drm_fb_helper_setcmap, and the struct psbfb_unaccel_ops implements two additional members: .fb_setcmap = drm_fb_helper_setcmap, .fb_pan_display = drm_fb_helper_pan_display, These changes are not tested.
