This makes it easier to verify correct dpll setup with only a single crtc. It is also useful to detect double dpll enable/disable. Changes since v1: - Rebase on top of Ander's dpll rework. - Change debugfs active to a mask. - Change enabled_crtcs and active_crtcs to unsigned. Signed-off-by:

After unplugging a DP MST display from the system, we have to go through and destroy all of the DRM connectors associated with it since none of them are valid anymore. Unfortunately, intel_dp_destroy_mst_connector() doesn't do a good enough job of ensuring that throughout the destruction process that no modesettings can be done with the connectors. As it is right now, intel_dp_destroy_mst_connector() works like this: * Take all modeset locks * Clear the configuration of the crtc on the connector, if there is one * Drop all modeset locks, this is required because of circular dependency issues that arise with trying to remove the connector from sysfs with modeset locks held * Unregister the connector * Take all modeset locks, again * Do the rest of the required cleaning for destroying the connector * Finally drop all modeset locks for good This only works sometimes. During the destruction process, it's very possible that a userspace application will attempt to do a modesetting using the connector. When we drop the modeset locks, an ioctl handler such as drm_mode_setcrtc has the oppurtunity to take all of the modeset locks from us. When this happens, one thing leads to another and eventually we end up committing a mode with the non-existent connector: [drm:intel_dp_link_training_clock_recovery [i915]] *ERROR* failed to enable link training [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_dp_start_link_train [i915]] *ERROR* failed to start channel equalization [drm:intel_dp_aux_ch] dp_aux_ch timeout status 0x7cf0001f [drm:intel_mst_pre_enable_dp [i915]] *ERROR* failed to allocate vcpi And in some cases, such as with the T460s using an MST dock, this results in breaking modesetting and/or panicking the system. To work around this, we now unregister the connector at the very beginning of intel_dp_destroy_mst_connector(), grab all the modesetting locks, and then hold them until we finish the rest of the function.

This version of GuC firmware fixes the engine reset issue where golden context LRC address is treated as page index by mistake. It also fixes the problem that scheduler stops submiting to one engine when the other engine work queue is full. Signed-off-by:

Favor a single point of truth instead of duplicating the information. The change also filters out unsupported DSI ports at this stage, accepting only ports A and C, instead of waiting until the port checks. Reviewed-by:

A small step moving us closer to DRM MIPI DSI code. Use enum mipi_dsi_pixel_format instead of our own. The first benefit is being able to use common mipi_dsi_pixel_format_to_bpp(). There's a little back and forth conversion with the VBT -> enum -> register, since we have just shoved the VBT value into the register directly. Longer term, all the VBT parsing and deciphering should be done in intel_bios.c, and abstracted there. Reviewed-by:

The enum mipi_dsi_pixel_format defines MIPI_DSI_FMT_RGB666 for the "loose" 24 bpp format and MIPI_DSI_FMT_RGB666_PACKED for the 18 bpp format. We have this the other way round, defining a loose version for 24 bpp. Follow suit with what's in enum mipi_dsi_pixel_format to avoid future confusion. Rename VID_MODE_FORMAT_RGB666 -> VID_MODE_FORMAT_RGB666_PACKED VID_MODE_FORMAT_RGB666_LOOSE -> VID_MODE_FORMAT_RGB666 Reviewed-by:

The Raspberry Pi Foundation's firmware updates are shipping device trees using the old string, so we'll keep recognizing that as this rev of V3D. Still, we should use a more specific name in the upstream DT to clarify which board is being supported, in case we do other revs of V3D in the future. Signed-off-by:
