There's no reason to track the atomic state three times. Unfortunately, this is currently what we're doing, and even worse is that there is only one actually correct state pointer: the one in mst_state->base.state. mgr->state never seems to be used, along with the one in mst_state->state. This confused me for over 4 hours until I realized there was no magic behind these pointers. So, let's save everyone else from the trouble. Signed-off-by: Lyude Paul <lyude@redhat.com>.

Because we have drm_dp_atomic_find_vcpi_slots(), which actually takes care to update the atomic state of the MST topology, prints valuable debugging output, and actually takes references to the ports it's checking! This explains some incorrect usage I've been seeing across the tree... Signed-off-by:

When vc4_plane_state is duplicated ->is_yuv is left assigned to its previous value, and we never set it back to false when switching to a non-YUV format. Fix that by setting ->is_yuv to false in the 'num_planes == 1' branch of the vc4_plane_setup_clipping_and_scaling() function. Fixes: fc04023f ("drm/vc4: Add support for YUV planes.")

X/Y positioning of T-format buffers is quite tricky and the current implementation was failing to position a plane using this format correctly when the CRTC X, Y or both X and Y offsets were negative. It was also failing when the SRC X/Y offsets were != 0. Signed-off-by:

The offset adjustment depends on the framebuffer modified, so let's just move this operation in the DRM_FORMAT_MOD_LINEAR case inside vc4_plane_mode_set(). This we'll be able to fix offset calculation for DRM_FORMAT_MOD_BROADCOM_VC4_T_TILED and DRM_FORMAT_MOD_BROADCOM_SANDXXX. Signed-off-by:

drm_atomic_helper_check_plane_state() takes care of checking the scaling capabilities and calculating the clipped X/Y offsets for us. Rely on this function instead of open-coding the logic. Incidentally, it seems to fix a problem we had with negative X/Y positioning of YUV planes. Signed-off-by:

The DSI devices have a maximum operating frequency specified in their data sheet per the MIPI specification, and DSI hosts that can scale their frequency need this information to set their clock dividers right. As current panel drivers often lack this information, specify that setting it to zero will make the DSI host use some reasonable default. Reviewed-by:

This patch is for VK_KHR_timeline_semaphore extension, semaphore is called syncobj in kernel side: This extension introduces a new type of syncobj that has an integer payload identifying a point in a timeline. Such timeline syncobjs support the following operations: * CPU query - A host operation that allows querying the payload of the timeline syncobj. * CPU wait - A host operation that allows a blocking wait for a timeline syncobj to reach a specified value. * Device wait - A device operation that allows waiting for a timeline syncobj to reach a specified value. * Device signal - A device operation that allows advancing the timeline syncobj to a specified value. v1: Since it's a timeline, that means the front time point(PT) always is signaled before the late PT. a. signal PT design: Signal PT fence N depends on PT[N-1] fence and signal opertion fence, when PT[N] fence is signaled, the timeline will increase to value of PT[N]. b. wait PT design: Wait PT fence is signaled by reaching timeline point value, when timeline is increasing, will compare wait PTs value with new timeline value, if PT value is lower than timeline value, then wait PT will be signaled, otherwise keep in list. syncobj wait operation can wait on any point of timeline, so need a RB tree to order them. And wait PT could ahead of signal PT, we need a sumission fence to perform that. v2: 1. remove unused DRM_SYNCOBJ_CREATE_TYPE_NORMAL. (Christian) 2. move unexposed denitions to .c file. (Daniel Vetter) 3. split up the change to drm_syncobj_find_fence() in a separate patch. (Christian) 4. split up the change to drm_syncobj_replace_fence() in a separate patch. 5. drop the submission_fence implementation and instead use wait_event() for that. (Christian) 6. WARN_ON(point != 0) for NORMAL type syncobj case. (Daniel Vetter) v3: 1. replace normal syncobj with timeline implemenation. (Vetter and Christian) a. normal syncobj signal op will create a signal PT to tail of signal pt list. b. normal syncobj wait op will create a wait pt with last signal point, and this wait PT is only signaled by related signal point PT. 2. many bug fix and clean up 3. stub fence moving is moved to other patch. v4： 1. fix RB tree loop with while(node=rb_first(...)). (Christian) 2. fix syncobj lifecycle. (Christian) 3. only enable_signaling when there is wait_pt. (Christian) 4. fix timeline path issues. 5. write a timeline test in libdrm v5: (Christian) 1. semaphore is called syncobj in kernel side. 2. don't need 'timeline' characters in some function name. 3. keep syncobj cb. v6: (Christian) 1. merge syncobj_timeline to syncobj structure. 2. simplify some check sentences. 3. some misc change. 4. fix CTS failed issue. v7: (Christian) 1. error handling when creating signal pt. 2. remove timeline naming in func. 3. export flags in find_fence. 4. allow reset timeline. v8: 1. use wait_event_interruptible without timeout 2. rename _TYPE_INDIVIDUAL to _TYPE_BINARY v9: 1. rename signal_pt->base to signal_pt->fence_array to avoid misleading 2. improve kerneldoc individual syncobj is tested by ./deqp-vk -n dEQP-VK*semaphore* timeline syncobj is tested by ./amdgpu_test -s 9 Signed-off-by: -

If BIOS configured a Y tiled FB we failed to set up the backing object tiling accordingly, leading to a lack of GT fence installed and a garbled console. The problem was bisected to commit 011f22eb ("drm/i915: Do NOT skip the first 4k of stolen memory for pre-allocated buffers v2") but it just revealed a pre-existing issue.

This patch fixes the original commit c0cfb10d ("drm/i915/edp: Do not do link training fallback or prune modes on EDP") that causes a blank screen in case of certain eDP panels (Eg: seen on Dell XPS13 9350) where first link training fails and a retraining is required by falling back to lower link rate/lane count. In case of some panels they advertise higher link rate/lane count than whats required for supporting the panel's native mode. But we always link train at highest link rate/lane count for eDP and if that fails we can still fallback to lower link rate/lane count as long as the fallback link BW still fits the native mode to avoid pruning the panel's native mode yet retraining at fallback values to recover from a blank screen. v3: * Add const for fixed_mode (Ville) v2: * Send uevent if link failure on eDP unconditionally Fixes: c0cfb10d ("drm/i915/edp: Do not do link training fallback or prune modes on EDP") Cc: Clinton Taylor <clinton.a.taylor@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjala <ville.syrjala@linux.intel.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Lucas De Marchi <lucas.demarchi@intel.com> Cc: <stable@vger.kernel.org> # v4.17+ Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107489 Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105338Signed-off-by:

Currently, i915 appears to rely on blocking modesets on no-longer-present MSTB ports by simply returning NULL for ->best_encoder(), which in turn causes any new atomic commits that don't disable the CRTC to fail. This is wrong however, since we still want to allow userspace to disable CRTCs on no-longer-present MSTB ports by changing the DPMS state to off and this still requires that we retrieve an encoder. So, fix this by always returning a valid encoder regardless of the state of the MST port. Changes since v1: - Remove mst atomic helper, since this got replaced with a much simpler solution Signed-off-by:

Since we need to be able to allow DPMS on->off prop changes after an MST port has disappeared from the system, we need to be able to make sure we can compute a config for the resulting atomic commit. Currently this is impossible when the port has disappeared, since the VCPI slot searching we try to do in intel_dp_mst_compute_config() will fail with -EINVAL. Since the only commits we want to allow on no-longer-present MST ports are ones that shut off display hardware, we already know that no VCPI allocations are needed. So, hardcode the VCPI slot count to 0 when intel_dp_mst_compute_config() is called on an MST port that's gone. Changes since V4: - Don't use mst_port_gone at all, just check whether or not the drm connector is registered - Daniel Vetter Signed-off-by:
