That way we can also remove a bunch of checks like intel_crtc_is_bigjoiner_slave. v2: - Moved skl_pfit_enable, intel_dsc_enable, intel_crtc_vblank_on to intel_enable_ddi, so that it is now finally symmetrical with the disable case, because currently for some weird reason we are calling those from skl_commit_modeset_enables, while for the disable case those are called from the ddi disable hooks. v3: - Create intel_ddi_enable_hdmi_or_sst symmetrical to intel_ddi_post_disable_hdmi_or_sst and move it also under non-mst check. v4: - Fix intel_enable_ddi sequence - Call intel_crtc_update_active_timings for slave pipes as well [v5: vsyrjala: Use the name 'pipe_crtc' for the per-pipe crtc pointer Use consistent style and naming Protect macro arguments properly Drop superfluous changes to the modeset sequence, this now follows the old non-joiner sequence 100% apart from just looping in places] Signed-off-by: Stanislav Lisovskiy <stanislav.lisovskiy@intel.com> Tested-by: Vidya Srinivas <vidya.srinivas@intel.com> Reviewed-by: Manasi Navare <navaremanasi@chromium.org> #v4?

2024-04-11drm/i915: Add SIZE_HINTS property for cursorsVille Syrjälä
Advertize more suitable cursor sizes via the new SIZE_HINTS plane property. We can't really enumerate all supported cursor sizes on the platforms where the cursor height can vary freely, so for simplicity we'll just expose all square+POT sizes between each platform's min and max cursor limits. Depending on the platform this will give us one of three results: - 64x64,128x128,256x256,512x512 - 64x64,128x128,256x256 - 64x64 Cc: Simon Ser <contact@emersion.fr> Cc: Jonas Ådahl <jadahl@redhat.com> Cc: Daniel Stone <daniel@fooishbar.org> Cc: Sameer Lattannavar <sameer.lattannavar@intel.com> Cc: Sebastian Wick <sebastian.wick@redhat.com> Cc: Harry Wentland <harry.wentland@amd.com> Cc: Pekka Paalanen <pekka.paalanen@collabora.com> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240318204408.9687-3-ville.syrjala@linux.intel.com Reviewed-by: Juha-Pekka Heikkila <juhapekka.heikkila@gmail.com>
2024-04-11drm: Introduce plane SIZE_HINTS propertyVille Syrjälä
Add a new immutable plane property by which a plane can advertise a handful of recommended plane sizes. This would be mostly exposed by cursor planes as a slightly more capable replacement for the DRM_CAP_CURSOR_WIDTH/HEIGHT caps, which can only declare a one size fits all limit for the whole device. Currently eg. amdgpu/i915/nouveau just advertize the max cursor size via the cursor size caps. But always using the max sized cursor can waste a surprising amount of power, so a better strategy is desirable. Most other drivers don't specify any cursor size at all, in which case the ioctl code just claims that 64x64 is a great choice. Whether that is actually true is debatable. A poll of various compositor developers informs us that blindly probing with setcursor/atomic ioctl to determine suitable cursor sizes is not acceptable, thus the introduction of the new property to supplant the cursor size caps. The compositor will now be free to select a more optimal cursor size from the short list of options. Note that the reported sizes (either via the property or the caps) make no claims about things such as plane scaling. So these things should only really be consulted for simple "cursor like" use cases.

2024-04-10drm/nouveau/dp: Don't probe eDP ports twice harderLyude Paul
I didn't pay close enough attention the last time I tried to fix this problem - while we currently do correctly take care to make sure we don't probe a connected eDP port more then once, we don't do the same thing for eDP ports we found to be disconnected. So, fix this and make sure we only ever probe eDP ports once and then leave them at that connector state forever (since without HPD, it's not going to change on its own anyway). This should get rid of the last few GSP errors getting spit out during runtime suspend and resume on some machines, as we tried to reprobe eDP ports in response to ACPI hotplug probe events.

2024-04-10drm/nouveau/kms/nv50-: Disable AUX bus for disconnected DP portsLyude Paul
GSP has its own state for keeping track of whether or not a given display connector is plugged in or not, and enforces this state on the driver. In particular, AUX transactions on a DisplayPort connector which GSP says is disconnected can never succeed - and can in some cases even cause unexpected timeouts, which can trickle up to cause other problems. A good example of this is runtime power management: where we can actually get stuck trying to resume the GPU if a userspace application like fwupd tries accessing a drm_aux_dev for a disconnected port. This was an issue I hit a few times with my Slimbook Executive 16 - where trying to offload something to the discrete GPU would wake it up, and then potentially cause it to timeout as fwupd tried to immediately access the dp_aux_dev nodes for nouveau. Likewise: we don't really have any cases I know of where we'd want to ignore this state and try an aux transaction anyway - and failing pointless aux transactions immediately can even speed things up. So - let's start enabling/disabling the aux bus in nouveau_dp_detect() to fix this. We enable the aux bus during connector probing, and leave it enabled if we discover something is actually on the connector. Otherwise, we just shut it off. This should fix some people's runtime PM issues (like myself), and also get rid of quite of a lot of GSP error spam in dmesg.

2024-04-10drm/xe: re-order lmem init check and wait for initialization to completeRiana Tauro
Lmem init check should be done only after pcode initialization status is complete. Move lmem init check after pcode status check. Also wait for a short while after pcode status check to allow completion of the task. Failing to do so, can lead to aborting the module load leaving the system unusable.

2024-04-10drm/bridge: imx8mp-hdmi-tx: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
