Subject: [PATCH v4 4/8] drm/i915: Disable framebuffer compression for i915 driver in VM
Date: Tue, 10 Feb 2015 19:05:50 +0800 [thread overview]
Message-ID: <1423566354-5532-5-git-send-email-yu.c.zhang@linux.intel.com> (raw)
In-Reply-To: <1423566354-5532-1-git-send-email-yu.c.zhang@linux.intel.com>
Framebuffer compression is disabled when driver detects it's
running in a Intel GVT-g enlightened VM, because FBC is not
emulated and there is no stolen memory for a vGPU.
v2:
take Chris' comments:
- move the code into intel_update_fbc()
v4:
take Tvrtko's comments:
- rebase the code into intel_fbc_update()
