Subject: [Intel-gfx] [CI 09/11] drm/i915/dg1: DG1 does not support DC6
Date: Wed, 14 Oct 2020 12:19:35 -0700	[thread overview]
Message-ID: <20201014191937.1266226-9-lucas.demarchi@intel.com> (raw)
In-Reply-To: <20201014191937.1266226-1-lucas.demarchi@intel.com>

From: Anshuman Gupta <anshuman.gupta@intel.com>

DC6 is not supported on DG1, so change the allowed DC mask for DG1.
This is not yet on bspec, but it has been confirmed by HW engineers.
