| * | | | drm/i915: fix the transition minimums for gen9+ watermarksPaulo Zanoni2018-10-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The transition minimum is 14 blocks for gens 9 and 10, and 4 blocks for gen 11. This minimum value is supposed to be added to the configurable trans_amount. This matches both BSpec and additional information provided by our HW engineers.

| * | | | drm/i915: DRM_FORMAT_C8 is not possible with Yf tilingPaulo Zanoni2018-10-111-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

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.

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: c0cfb10d9e1d ("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=105338 Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Tested-by: Alexander Wilson <alexander.wilson@ncf.edu> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20181009212804.702-1-manasi.d.navare@intel.com

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.

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.

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.

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.

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=107749 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com> #v1 Link: https://patchwork.freedesktop.org/patch/msgid/20181004121527.30249-1-ville.syrjala@linux.intel.com
