2024-03-01drm/sun4i: hdmi: Add missing drm_atomic headerMaxime Ripard1-0/+1
Commit 358e76fd613a ("drm/sun4i: hdmi: Consolidate atomic_check and mode_valid") added a call to drm_atomic_get_new_connector_state() but didn't include drm_atomic.h which defines it. On some configuration, this leads to a build failure, presumably because in the common case the header gets included by an intermediate header but it isn't always the case. Let's add a proper include.

2024-02-29drm/mediatek: Fix a null pointer crash in mtk_drm_crtc_finish_page_flipHsin-Yi Wang1-5/+7
It's possible that mtk_crtc->event is NULL in mtk_drm_crtc_finish_page_flip(). pending_needs_vblank value is set by mtk_crtc->event, but in mtk_drm_crtc_atomic_flush(), it's is not guarded by the same lock in mtk_drm_finish_page_flip(), thus a race condition happens. Consider the following case: CPU1 CPU2 step 1: mtk_drm_crtc_atomic_begin() mtk_crtc->event is not null, step 1: mtk_drm_crtc_atomic_flush: mtk_drm_crtc_update_config( !!mtk_crtc->event) step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip: lock mtk_crtc->event set to null, pending_needs_vblank set to false unlock pending_needs_vblank set to true, step 2: mtk_crtc_ddp_irq -> mtk_drm_finish_page_flip called again, pending_needs_vblank is still true //null pointer Instead of guarding the entire mtk_drm_crtc_atomic_flush(), it's more efficient to just check if mtk_crtc->event is null before use.

2024-02-28drm/dp: Don't attempt AUX transfers when eDP panels are not poweredDouglas Anderson4-0/+46
If an eDP panel is not powered on then any attempts to talk to it over the DP AUX channel will timeout. Unfortunately these attempts may be quite slow. Userspace can initiate these attempts either via a /dev/drm_dp_auxN device or via the created i2c device. Making the DP AUX drivers timeout faster is a difficult proposition. In theory we could just poll the panel's HPD line in the AUX transfer function and immediately return an error there. However, this is easier said than done. For one thing, there's no hard requirement to hook the HPD line up for eDP panels and it's OK to just delay a fixed amount. For another thing, the HPD line may not be fast to probe. On parade-ps8640 we need to wait for the bridge chip's firmware to boot before we can get the HPD line and this is a slow process. The fact that the transfers are taking so long to timeout is causing real problems. The open source fwupd daemon sometimes scans DP busses looking for devices whose firmware need updating. If it happens to scan while a panel is turned off this scan can take a long time. The fwupd daemon could try to be smarter and only scan when eDP panels are turned on, but we can also improve the behavior in the kernel. Let's let eDP panels drivers specify that a panel is turned off and then modify the common AUX transfer code not to attempt a transfer in this case.

In drm_kms_helper_poll_disable() check if output polling support is initialized before disabling polling. If not flag this as a warning. Additionally in drm_mode_config_helper_suspend() and drm_mode_config_helper_resume() calls, that re the callers of these functions, avoid invoking them if polling is not initialized. For drivers like hyperv-drm, that do not initialize connector polling, if suspend is called without this check, it leads to suspend failure with following stack [ 770.719392] Freezing remaining freezable tasks ...

2024-02-27drm/i915/dp: Read DPRX for all long HPD pulsesImre Deak1-0/+12
The TBT DP tunnel BW request logic in the Thunderbolt Connection Manager depends on the GFX driver reading out the sink's DPRX capabilities in response to a long HPD pulse. Since in i915 this read-out can be blocked by another connector's/encoder's hotplug event handling (which is serialized by drm_mode_config::connection_mutex), do a dummy DPRX read-out in the encoder's HPD pulse handler (which is not blocked by other encoders).

Suspend and resume DP tunnels during system suspend/resume, disabling the BW allocation mode during suspend, re-enabling it after resume. This reflects the link's BW management component (Thunderbolt CM) disabling BWA during suspend. Before any BW requests the driver must read the sink's DPRX capabilities (since the BW manager requires this information, so snoops for it on AUX), so ensure this read takes place.
