drm/loongson: Create blend mode property for cursor plane

2026-09-17T07:12:26+00:00

After commit 860e748bddcc929 ("drm: ensure blend mode supported if pixel format with alpha exposed") we get warnings at boot: loongson 0000:00:06.1: [drm] [PLANE:41:ls-cursor-plane-0] pixel format with alpha exposed but blend mode not setup. Please fix. loongson 0000:00:06.1: [drm] [PLANE:46:ls-cursor-plane-1] pixel format with alpha exposed but blend mode not setup. Please fix. The reason is the cursor plane supports color formats with alpha but the driver doesn't create blend mode property, which triggers the warning in validate_blend_mode_for_alpha_formats(). The loongson DC HW doesn't support DRM_MODE_BLEND_PREMULTI, so create blend mode property with DRM_MODE_BLEND_COVERAGE for cursor planes since it is the only one implemented in the driver.

Revert "drm/i915/display: Clear SEL_FETCH_PLANE_CTL on plane disable"

2026-09-16T09:55:22+00:00

This reverts commit 7f1172a2ac0d7e50850785e2e65789c8aac8411a. This commit replaced the crtc_state->enable_psr2_sel_fetch guard in icl_plane_disable_sel_fetch_arm() and i9xx_cursor_disable_sel_fetch_arm() with HAS_PSR2_SEL_FETCH(). This is a display version check and says nothing about the pipe, so every plane and cursor disable on a display 12+ platform started writing SEL_FETCH_PLANE_CTL() / SEL_FETCH_CUR_CTL(), including on pipes that do not implement them. It shows up as an unclaimed register access on pipes driving HDMI where selective fetch was never enabled. The stale selective fetch enable bit that commit addressed is handled in the next patch.

drm/verisilicon: remove ARGB formats from primary plane

2026-09-16T09:41:25+00:00

As the blending of the primary plane is currently explicitly disabled (and it's not possible on DC8000), remove the ARGB formats from the primary plane format tables.

drm/verisilicon: set blend mode for the cursor plane

2026-09-16T09:39:55+00:00

Blend mode properties are now required to expose pixel formats w/ alpha. Experiments show that the fixed blending mode for the cursor seems to be COVERAGE: - With a cursor plane filled with R=G=0, B=0xff, A=0x40, the cursor is visible on a pure-white background, which means the background is multiplied. - With a cursor plane filled with R=G=B=0xff, A=0x40, the cursor isn't pure white and non-white patterns can be see through, which means the cursor is multiplied. Add a fixed COVERAGE blend mode property for the cursor plane.

drm/sched: Fix virtual runtime race

2026-09-16T07:17:51+00:00

Prevent pushing a new job to an entity seeing it being the first in the queue, and hence entering the drm_sched_rq_add_entity() path, if the pop side in drm_sched_entity_pop_job() has just de-queued the job but not yet updated the saved virtual time. Restoring the unsaved virtual time, which is at this point not a delta but still an absolute value, pushes the said entity to the rear of the run queue for a potentially very long time. We close this race by pulling the locked sections out to encompass both the queue push/pop and corresponding rbtree management. This is aligned with the future direction to replace the current lockless job queue with one of the fully locked standard list primitives.
