Subject: [PATCH 0/2] hibmc: Improve vblank handling
Date: Thu, 27 Aug 2026 10:23:43 +0200 [thread overview]
Message-ID: <20260827082915.61176-1-tzimmermann@suse.de> (raw)
Vblank event handling in hibmc is currently somewhat disconnected
from what the hardware does. Patch 1 updates IRQ handlers to signal
whether the driver handled an IRQ or not. Patch 2 connects hibmc's
vblank events to the hardware's vblank interrupts.
Tested on an RH1288 v3 system.
Thomas Zimmermann (2):
drm/hibmc: Return IRQ_NONE for unhandled interrupts
drm/hibmc: Set up vblank event to be send on the next vblank
