Subject: [RFC PATCH nixpkgs v2 7/9] cloud-hypervisor: add virtio-gpu support
Date: Fri, 30 Sep 2022 21:09:04 +0000 [thread overview]
Message-ID: <20220930210906.1696349-8-alyssa.ross@unikie.com> (raw)
In-Reply-To: <20220930210906.1696349-1-alyssa.ross@unikie.com>
The virtio-bindings changes update the bindings for recent kernels,
and the vhost change is cherry-picked from crosvm's fork of the crate
to add support for their custom extensions.

+From: Alyssa Ross <alyssa.ross@unikie.com>
+Date: Wed, 7 Sep 2022 14:16:29 +0000
+Subject: [PATCH 3/3] virtio-devices: add a GPU device
+
+This adds support for exposing a virtio-gpu device to guest by
+implementing a vhost-user frontend compatible with crosvm's GPU device
+backend.
+
+Note that this is not the same as the "vhost-user-gpu" protocol
+implemented by QEMU.
+
+Adding a GPU device from the command line looks like this:
+
+ --gpu socket=/path/to/crosvm-gpu-vhost-user.sock
+
+As a workaround, We fall back to trying to map shared memory as
+read-only if it can't be mapped read-write, because wlroots' keymaps
+are read-only, and crosvm does not properly handle this, causing
+cloud-hypervisor to crash.

+Date: Wed, 15 Jun 2022 16:45:12 +0900
+Subject: [PATCH] vhost_user: add shared memory region support
+
+Add support for shared memory regions to vhost-user. This is adding
+support for a front-end message to query for necessary shared memory
+regions plus back-end message to support mapping/unmapping files from
+the shared memory region.
