Subject: [PATCH v2 08/13] drm/i915/display: Store DC3CO eligibility in PSR state
Date: Wed, 22 Apr 2026 21:56:16 +0530	[thread overview]
Message-ID: <20260422162622.1869831-9-dibin.moolakadan.subrahmanian@intel.com> (raw)
In-Reply-To: <20260422162622.1869831-1-dibin.moolakadan.subrahmanian@intel.com>

Store DC3CO eligibility in intel_dp->psr during
intel_psr_post_plane_update() so PSR configuration
can take DC3CO into account.

This will be used to control PSR2 parameters such as idle frames.

Changes in v2:
- Use intel_display_power_dc3co_allowed(display) instead
  of intel_dc3co_allowed(state)
