[Intel-gfx] [PATCH] drm/i915/display: Read planes watermarks during initial state readout

Without this readout all plane watermarks will be kept at zero in the initial state readount causing two problems. All active planes will always have their watermarks programmed again, even if what firmware programmed matches with the sanitized state during driver takeover. State mismatch errors

[Intel-gfx] [PATCH 00/30] drm: Use new DRM printk funcs (like drm_dbg_*()) in DP helpers

Since it's been asked quite a few times on some of the various DP related patch series I've submitted to use the new DRM printk helpers, and it technically wasn't really trivial to do this before due to the lack of a consistent way to find a drm_device for an AUX channel, this patch series aims to

[Intel-gfx] [PATCH 03/30] drm/tegra: Don't register DP AUX channels before connectors

As pointed out by the documentation for drm_dp_aux_register(), drm_dp_aux_init() should be used in situations where the AUX channel for a display driver can potentially be registered before it's respective DRM driver. This is the case with Tegra, since the DP aux channel exists as a platform device

[Intel-gfx] [PATCH 04/30] drm/bridge/tc358767: Don't register DP AUX channel until bridge is attached

Since this is a bridge, we don't start out with a respective DRM device. Likewise this means we don't have a connector, which also means that we should be following drm_dp_aux_register()'s documentation advice and not call drm_dp_aux_register() until we have a matching connector. Instead, call drm_

[Intel-gfx] [PATCH 07/30] drm/bridge/analogix/anx78xx: Add missing drm_dp_aux_unregister() call

Surprisingly, this bridge actually registers it's AUX adapter at the correct time already. Nice job! However, it does forget to actually unregister the AUX adapter, so let's add a bridge function to handle that. Signed-off-by: Lyude Paul --- drivers/gpu/drm/bridge/analogix/analogix-anx78xx.c | 6

[Intel-gfx] [PATCH 09/30] drm/bridge/analogix/anx78xx: Cleanup on error in anx78xx_bridge_attach()

Just another issue I noticed while correcting usages of drm_dp_aux_init()/drm_dp_aux_register() around the tree. If any of the steps in anx78xx_bridge_attach() fail, we end up leaking resources. So, let's fix that (and fix leaking a DP AUX adapter in the process) by unrolling on errors. Signed-off

[Intel-gfx] [PATCH 06/30] drm/bridge/ti-sn65dsi86: (Un)register aux device on bridge attach/detach

Since we're about to add a back-pointer to drm_dev in drm_dp_aux, let's move the AUX adapter registration to the first point where we know which DRM device we'll be working with - when the drm_bridge is attached. Likewise, we unregister the AUX adapter on bridge detachment by adding a ti_sn_bridge_

[Intel-gfx] [PATCH 17/30] drm/dp: Clarify DP AUX registration time

This is the case for most normal GPUs, but is almost never the case with SoCs and display b

[Intel-gfx] [PATCH 15/30] drm/dp: Add backpointer to drm_device in drm_dp_aux

This is something that we've wanted for a while now: the ability to actually look up the respective drm_device for a given drm_dp_aux struct.
