Subject: [PATCH v3 0/2] Block DC6 on Vblank enable for Panel Replay
Date: Tue, 17 Sep 2024 09:35:58 +0300 [thread overview]
Message-ID: <20240917063600.3086259-1-jouni.hogander@intel.com> (raw)
We need to block DC6 entry in case of Panel Replay as enabling VBI doesn't
prevent DC6 in case of Panel Replay. This causes problems if user-space is
polling for vblank events.
v3: check that encoder is dp
v2: set/clear block_dc6_needed in intel_crtc_vblank_on/off
Jouni Högander (2):
drm/i915/display: Add block_dc6_needed variable into intel_crtc
drm/i915/display: Prevent DC6 while vblank is enabled for Panel Replay
