| * drm/i915: Reject the colorkey ioctls for primary and cursor planesVille Syrjälä2015-04-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The legcy colorkey ioctls are only implemented for sprite planes, so reject the ioctl for primary/cursor planes. If we want to support colorkeying with these planes (assuming we have hw support of course) we should just move ahead with the colorkey property conversion.

|/ | | | | | | | | | | | | | | | | | Since the mapping from CRTCs to planes is fixed, looking at the CRTC is essentially the same as looking at the plane. Also, the next patches wil start using the frontbuffer_bits macros, and they take the pipe as the parameter instead of the plane, and this could differ on gens 2 and 3.

This means that rather than provide our own implementations of .update_plane() and .disable_plane(), we expose the lower-level check/prepare/commit/cleanup entrypoints and let the DRM core implement update/disable for us using those entrypoints. The other main change that falls out of this patch is that our drm_plane's will now always have a valid plane->state that contains the relevant plane state (initial state is allocated at plane creation). The base drm_plane_state pointed to holds the requested source/dest coordinates, and the subclassed intel_plane_state holds the adjusted values that our driver actually uses. v2: - Renamed file from intel_atomic.c to intel_atomic_plane.c (Daniel) - Fix a copy/paste comment mistake (Bob) v3: - Use prepare/cleanup functions that we've already factored out - Use newly refactored pre_commit/commit/post_commit to avoid sleeping during vblank evasion v4: - Rebase to latest di-nightly requires adding an 'old_state' parameter to atomic_update; v5: - Must have botched a rebase somewhere and lost some work. Restore state 'dirty' flag to let begin/end code know which planes to run the pre_commit/post_commit hooks for. This would have actually shown up as broken in the next commit rather than this one. v6: - Squash kerneldoc patch into this one. - Previous patches have now already taken care of most of the infrastructure that used to be in this patch. All we're adding here now is some thin wrappers. v7: - Check return of intel_plane_duplicate_state() for allocation failures. v8: - Drop unused drm_plane_state -> intel_plane_state cast.

The only fb's we need to update frontbuffer tracking for are those on a plane about to be disabled (since the atomic helpers never call prepare_fb() when disabling a plane), so the new name more accurately describes what we're actually tracking.

Rename a few functions to be more consistent with our function naming for primary/cursor planes or to clarify that they apply specifically to sprite planes: - s/intel_disable_planes/intel_disable_sprite_planes/ - s/intel_enable_planes/intel_enable_sprite_planes/ Also, drop the sprite-specific intel_destroy_plane() and just use the type-agnostic intel_plane_destroy() function.

* drm/i915: Refactor work that can sleep out of commit (v7)Matt Roper2015-01-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Once we integrate our work into the atomic pipeline, plane commit operations will need to happen with interrupts disabled, due to vblank evasion. Our commit functions today include sleepable work, so those operations need to be split out and run either before or after the atomic register programming. The solution here calculates which of those operations will need to be performed during the 'check' phase and sets flags in an intel_crtc sub-struct. New intel_begin_crtc_commit() and intel_finish_crtc_commit() functions are added before and after the actual register programming; these will eventually be called from the atomic plane helper's .atomic_begin() and .atomic_end() entrypoints. v2: Fix broken sprite code split v3: Make the pre/post commit work crtc-based to match how we eventually want this to be called from the atomic plane helpers. v4: Some platforms that haven't had their watermark code reworked were waiting for vblank, then calling update_sprite_watermarks in their platform-specific disable code. These also need to be flagged out of the critical section. v5: Sprite plane test for primary show/hide should just set the flag to wait for pending flips, not actually perform the wait.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we extend the commit_plane handlers for each plane type to be able to handle fb=0, then we can easily implement plane disable via the update_plane handler.

Note that prepare_plane_fb() only gets called as part of update_plane when fb!=NULL (by design, to match the semantics of the atomic plane helpers); this means that our commit_plane handlers need to handle the frontbuffer tracking for the disable case, even though they don't handle it for normal updates. v2: - Change BUG_ON to WARN_ON (Ander/Daniel) v3: - Drop unnecessary plane->crtc check since a previous patch to plane update ensures that plane->crtc will always be non-NULL, even for disable calls that might pass NULL from userspace. (Ander) - Drop a s/crtc/plane->crtc/ hunk that was unnecessary. (Ander) v4: - Fix missing whitespace (Ander) v5: - Use state's crtc rather than plane's crtc in intel_check_primary_plane(). plane->crtc could be NULL, but we've already fixed up state->crtc to ensure it's non-NULL (even if userspace passed it as NULL during a disable call).

| | | | | | | | | | | | | | | | | | | | | | | Currently we program just DPSCNTR and DSPSTRIDE directly from the ring interrupt handler, which is fine since the hardware guarantees that those are update atomically. When we have atomic page flips we'll want to be able to update also the offset registers, and then we need to use the vblank evade mechanism to guarantee atomicity. Since that mechanism introduces a wait, we need to do the actual register write from a work when it is triggered by the ring interrupt. v2: Explain the need for mmio_flip.work in the commit message (Paulo) Initialize the mmio_flip work in intel_crtc_init() (Paulo) Prevent new flips the previous flip work finishes (Paulo) Don't acquire modeset locks for mmio flip work Note: Paulo had reservations about the work item leaking over a plane disable.

* drm/i915: Add support for CHV pipe B sprite CSCVille Syrjälä2014-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CHV has a programmable CSC unit on the pipe B sprites. Program the unit appropriately for BT.601 limited range YCbCr to full range RGB color conversion. This matches the programming we currently do for sprites on the other pipes and on other platforms. It seems the CSC only works when the input data is YCbCr. For RGB pixel formats it doesn't matter what we program into the CSC registers. Doesn't make much sense to me especially since the register names give the impression that RGB input data would also work. But that's how it behaves here. In the review discussions there's been some nice math to explain the values obtained here. First about the YCbCr->RGB matrix: "I had the RGB->YCbCr matrix, inverted it and the values came out. But they should match the wikipedia article. Also keep in mind that the coefficients are in .12 in fixed point format, hence we need a 1<<12 factor. So let's try it: Kb=.114 Kr=.299 (1<<12) * 255/219 ~= 4769 -(1<<12) * 255/112*(1-Kb)*Kb/(1-Kb-Kr) ~= -1605 -(1<<12) * 255/112*(1-Kr)*Kr/(1-Kb-Kr) ~= -3330 (1<<12) * 255/112*(1-Kr) ~= 6537 (1<<12) * 255/112*(1-Kb) ~= 8263 "Looks like the same values to me." And then about the limits used for clamping: "> where did you get these min/max? "The hardware apparently deals in 10bit values, so we need to multiply everything by 4 when we start with the 8bit min/max values. Y = [16:235] * 4 = [64:940] CbCr = ([16:240] - 128) * 4 = [-112:112] * 4 = [-448:448] "The -128 being the -0.5 bias that the hardware already applied before the data entered the CSC unit."

* drm/i915: Don't call intel_plane_restore() when the prop value didn't changeVille Syrjälä2014-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | No point in calling intel_plane_restore() in .set_property() if the value didn't change. More importantly this papers over a bug where the current primary plane code forgets to update the user coordinates we store under intel_plane unless the primary plane .update_plane() hook is actually called. This means we have 0 in the coordinates straight after boot and any call to intel_restore_plane() (such as from restore_fbdev_mode()) will actually turn off the primary plane. This mess needs to be fixed properly but that's a bigger task and the first step there is killing off intel_pipe_set_base() and just calling the primary plane .update_plane() hook. For the immediate problem of black screen after boot this small patch is enough to hide it. The problem originates from these two commits: commit 3a5f87c286515c54ff5c52c3e64d0c522b7570c0 Author: Thomas Wood <thomas.wood@intel.com> Date: Wed Aug 20 14:45:00 2014 +0100 drm: fix plane rotation when restoring fbdev configuration commit d91a2cb8e5104233c02bbde539bd4ee455ec12ac Author: Sonika Jindal <sonika.jindal@intel.com> Date: Fri Aug 22 14:06:04 2014 +0530 drm/i915: Add 180 degree primary plane rotation support Cc: Thomas Wood <thomas.wood@intel.com> Cc: Sonika Jindal <sonika.jindal@intel.com> Tested-by: Mika Kuoppala <mika.kuoppala@linux.intel.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Damien Lespiau <damien.lespiau@intel.com> Tested-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
