Merge airlied/drm-next into drm-misc-next

2017-07-26T11:43:33Z

I need this to be able to apply the deferred fbdev setup patches, I need the relevant prep work that landed through the drm-intel tree. Also squash in conflict fixup from Laurent Pinchart. Signed-off-by: Daniel Vetter

drm/atomic: Use the correct iterator macro in atomic_remove_fb

for_each_obj_in_state will be removed, so use the new state here. Signed-off-by: Maarten Lankhorst Cc: Daniel Vetter Cc: Jani Nikula Cc: Sean Paul Cc: David Airlie Link: http://patchwork.freedesktop.org/patch/msgid/20170712081344.25495-3-maarten.lankhorst@linux.intel.com Reviewed-by: Daniel Vetter

drm/atomic: Add missing drm_atomic_state_clear to atomic_remove_fb

2017-07-03T08:31:37Z

All atomic state should be cleared when drm_modeset_backoff() is called, because it drops all locks and the state becomes invalid. The call to drm_atomic_state_clear was missing in atomic_remove_fb, so add the missing call there.

drm: extract legacy framebuffer remove

2017-04-06T08:22:43Z

I got confused every time I audited what that lock_all is doing in there until realizing it's for legacy kms only. Make that a notch more obvious by having 2 entirely different paths. While at it also move the atomic version of this into drm_framebuffer.c, there's no reason it needs to be in drm_atomic.c. That way it becomes a simple static function.

drm: Add mode_config .get_format_info() hook

Allow drivers to return a custom drm_format_info structure for special fb layouts.

drm: Remove fb hsub/vsub alignment requirement

2017-03-22T17:44:15Z

Allow framebuffers dimesions to be misaligned w.r.t. the subsampling factors. No real reason the core should have to enforce this, and it definitely starts to cause us issues with the i915 CCS support. So let's just lift the restriction. Let's start to round up when computing the color plane dimesions so that we'll not end up with too low an estimate for the memory requirements and whatnot.

drm: Share the code to compute color plane dimesions

2017-03-22T17:37:17Z

framebuffer_check() has some hand rolled code to compute the color plane dimensions based on the subsampled information. Let's share the code between framebuffer_check() and drm_framebuffer_plane_{width,height}().

drm: Introduce drm_framebuffer_{get,put}()

2017-02-28T15:15:03Z

For consistency with other reference counting APIs in the kernel, add drm_framebuffer_get() and drm_framebuffer_put() to reference count DRM framebuffers. Compatibility aliases are added to keep existing code working. To help speed up the transition, all the instances of the old functions in the DRM core are already replaced in this commit. The existing semantic patch for the DRM subsystem-wide conversion is extended to account for these new helpers.

drm: Rename drm_mode_object_get()

2017-02-28T15:14:53Z

Subsequent patches will introduce reference counting APIs that are more consistent with similar APIs throughout the Linux kernel. These APIs use the _get() and _put() suffixes and will collide with this existing function. Rename the function to drm_mode_object_add() which is a slightly more accurate description of what it does. Also the kerneldoc for this function gives an indication that it's badly named because it doesn't actually acquire a reference to anything.

drm: Convert drm_framebuffer_remove to atomic, v4.

2017-02-28T12:06:48Z

Instead of trying to do everything in 1 go, just do a basic safe conversion first. We've been bitten by too many regressions in the past. This patch only converts drm_framebuffer_remove to atomic. The regression sensitive part is split out to a separate patch. v2: - Remove plane->fb assignment, done by drm_atomic_clean_old_fb. - Add WARN_ON when atomic_remove_fb fails. - Always call drm_atomic_state_put. v3: - Use drm_drv_uses_atomic_modeset - Handle the case where the first plane-disable-only commit fails with -EINVAL. Some drivers do not support this, fall back to disabling all crtc's in this case. v4: - Solve vmwgfx compatibility issue in their driver, was fixed in this patch by v3. - Move only disabling primary to a separate patch.
