Subject: [PATCH 5/6] drm/vmwgfx: Add basic support for SVGA3
Date: Wed, 5 May 2021 15:10:07 -0400 [thread overview]
Message-ID: <20210505191007.305872-1-zackr@vmware.com> (raw)
In-Reply-To: <20210505035740.286923-6-zackr@vmware.com>
SVGA3 is the next version of our PCI device. Some of the changes
include using MMIO for register accesses instead of ioports,
deprecating the FIFO MMIO and removing a lot of the old and
legacy functionality. SVGA3 doesn't support guest backed
objects right now so everything except 3D is working.
v2: Fixes all the static analyzer warnings
