We were writing to PLANE_BUF_CFG(pipe, plane_id) twice for every platform, and we were even using different values on the gen10- planar case. The first write is useless since it just gets replaced with the next one, so kill it. There's a lot to improve in the DDB code, but let's start by avoiding the double write. Reviewed-by:

The transition watermarks ask for Selected Result Blocks (the real value), not Result Blocks (the integer value). Given how ceilings are applied in both the non-transition and the transition watermarks calculations, we can get away with assuming that Selected Result Blocks is actually Result Blocks minus 1 without any rounding errors.

Function intel_framebuffer_init() checks for the possibilities during framebuffer creation (addfb ioctl time). It is missing the fact that the indexed format is not supported with Yf tiling. It is worth noticing that skl_plane_format_mod_supported() correctly handles for the C8/Yf combination, but this function runs during modeset time, so we only reject the combination later. Ville recently proposed a new IGT test that only uses addfb to assert supported formats, so that IGT was failing. Add the check so we get green squares right from the start after Ville merges his test. Also drive-by fix the missing /* fall through */ in the chunk we modified by just turning it into a "break;" since IMHO breaks are easier to read than fall-throughs.

As mentioned in the previous commit, we currently prevent new modesets on recently-removed MST connectors by returning no encoder from our ->best_encoder() callback once the MST port has disappeared. This is wrong however, because it prevents legacy modesetting users from being able to disable CRTCs on MST connectors after the connector's respective topology has disappeared. So, fix this by instead by just always returning a valid encoder. Changes since v2: - Remove usage of atomic MST helper for now, since that got replaced with a much simpler solution Signed-off-by:

Since this happens before the driver's registered with userspace, it's connectors are also unregistered and thus-states which would turn on DPMS on a connector end up getting rejected since the connector isn't registered. These bugs managed to get past Intel's CI partially due to the fact it never ran a full test on my patches for some reason, but also because all of the tests unload the GPU once before running. Since this bug is only really triggered when the drivers tries to perform a modeset before it's been fully registered with userspace when coming from whatever display configuration the firmware left us with, it likely would never have been picked up by CI in the first place. After some discussion with vsyrjala, we decided the best course of action would be to just move the unregistered connector checks out of update_connector_routing() and into drm_atomic_set_crtc_for_connector(). The reason for this being that legacy modesetting isn't going to be expecting failures anywhere (at least this is the case with X), so ideally we want to ensure that any DPMS changes will still work even on unregistered connectors. Instead, we now only reject new modesets which would change the current CRTC assigned to an unregistered connector unless no new CRTC is being assigned to replace the connector's previous one.

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.

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.

All CNL universal planes support horizontal mirroring. Currently we expose the capability only for the primary plane. Expose it for the overlay planes as well. Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Signed-off-by:

enum i9xx_plane_id namespace is not valid for any sprite plane, so let's not even populate plane->i9xx_plane. 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:
