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:

Almost all of the connector destroy functions do the same thing. The differences are in the edid, detect_edid and panel cleanups, but those are safely NULL when not initialized. Roll out a common connector destroy hook. Inspired by commit bc3213c4 ("drm/i915: Drop the eDP check from intel_dp_connector_destroy()").

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.

Currently we set intel_connector->mst_port to NULL to signify that the MST port has been removed from the system so that we can prevent further action on the port such as connector probes, mode probing, etc. However, we're going to need access to intel_connector->mst_port in order to fixup ->best_encoder() so that it can always return the correct encoder for an MST port to prevent legacy DPMS prop changes from failing. This should be safe, so instead keep intel_connector->mst_port always set and instead just check the status of drm_connector->regustered to signify whether or not the connector has disappeared from the system. Changes since v2: - Add a comment to mst_port_gone (Jani Nikula) - Change mst_port_gone to a u8 instead of a bool, per the kernel bot. Apparently bool is discouraged in structs these days Changes since v4: - Don't use mst_port_gone at all! Just check if the connector is registered or not - Daniel Vetter Signed-off-by:

With the exception of modesets which would switch the DPMS state of a connector from on to off, we want to make sure that we disallow all modesets which would result in enabling a new monitor or a new mode configuration on a monitor if the connector for the display in question is no longer registered. This allows us to stop userspace from trying to enable new displays on connectors for an MST topology that were just removed from the system, without preventing userspace from disabling DPMS on those connectors.

Currently we destroy the backlight during connector unregistration. That means the final modeset performed by drm_atomic_helper_shutdown() will leave the backlight on. We don't want that so let's just move intel_panel_destroy_backlight() into intel_panel_fini() which gets called during connector destuction. We still unregister the user visible backlight device during connector unregistration.

There's not much point in following the primary vs. sprite split for the SKL+ universal plane init code. The only difference is of our own doing in the form of the .check_plane(). Let's make a small exception for that little detail and otherwise share the same code to initialize all the universal planes. Eventually we should eliminate the mess around .check_plane() as well, but for now let's be happy with some code reduction. v2: Remember to set up plane->has_fbc Make skl_plane_has_ccs() static v3: Rebase due to NV12, rename some variables v4: Don't leave the color_encoding/range props behind v5: Rebase dur to blend properties, skl_plane_max_stride() and skl_plane_check() v6: Make skl_update_plane() static Signed-off-by: -

No point in having each caller of intel_create_plane_state() initialize the scaler_id to -1. Instead just do it in intel_create_plane_state(). Previously we left scaler_id at 0 for pre-SKL platforms, but I can't see how initializing it to -1 always would cause any harm. Signed-off-by:

We're currently not providing the possible_crtcs mask to drm_universal_plane_init() for primary/cursor planes. While that does work on account of drm_crtc_init_with_planes() filling those up for us, it's inconsisten with what we're doing for sprite planes. Let's just always pass the possible_crtcs bitmask to drm_universal_plane_init(). This does assume that crtc->index == pipe. But we're already making that assumption elsewhere so it doesn't seem like a very big sin here. Signed-off-by:

No functional change. But just a minor change to keep up with Spec, since it has changed since commit c3cc39c5 ("drm/i915/icl: program mbus during pipe enable") The instructions previously said to program pipe's B credit = 24 / number of pipes, which is 8 for ICL. Now the spec gives us direct values independent of number of pipes. Let's keep in sync. Also just a reorder on fields to make easier to compare against spec's sequence: A -> BW -> B.

Amber Lake used the same gen graphics as Kaby Lake. Kernel driver should configure KBL's DDI buffer setting for AML ULX as well. So far, driver would load DDI translation table that used for KBL H/S platform and apply it on AML devices. But AML is belong to ULX series. This change will lead driver to apply KBL-Y's DDI table for AML devices to avoid unexpected eDP/DP signal quality issue.

commit 'b9be7853 ("drm/i915/whl: Introducing Whiskey Lake platform")' introduced WHL by moving some of CFL IDs here and using the Spec information of "U43" for most of IDs what appeared to be GT3. However when propagating the change to Mesa, Lionel noticed that based on number of execution unities the classification here seems at least strange. So, let's move for now with the information we trust more: the number of EUs. So we are able to propagate this change across the stack without getting stuck forever.

Sprite enable on ILK-IVB may take two frames to complete when the hardware is in big FIFO mode (LP1+). That is not entirely great as it means the sprite enable may actually happen one frame after we've already signalled flip completion. At the very least crc checks may fail due to the sprite not yet being visible when we expect it. We already have code to deal with big FIFO mode when it comes to the sprite scaling on IVB (WaCxSRDisabledForSpriteScaling:ivb). Let's extend that workaround to kick in whenever the sprite is in the process of being enabled. Also ILK/SNB bspec has some notes to indicate that we should most likely also do the sprite scaling w/a on all three platforms, so let's do that as well. Pretty easy to reproduce on SNB/IVB. ILK has proved more elusive, but let's trust the spec and include it as well. v2: Make sure the pipe is active before the vblank wait Cc: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> Testcase: igt/kms_plane/pixel-format-pipe-*-planes Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107749Signed-off-by:
