 <h2>Can these patches be upstreamed?</h2>
 
 <p>
-I don’t think so.  The Cloud Hypervisor developers
-are <a href="https://github.com/cloud-hypervisor/cloud-hypervisor/issues/3212#issuecomment-937823742">not
-very interested</a> in GPU support — although perhaps an
-implementation that was just a vfio-user frontend implementation,
-deletaging all of the complexity of rendering, input handling, etc. to
-another process would be light enough to overcome that — but on top of
-that, communicating with crosvm’s GPU device requires using
-non-standard commands that are not part of
-the <a href="https://www.qemu.org/docs/master/interop/vhost-user.html">vhost-user
-specification</a>.

-<p>
-It’s possible that, in future, it might be possible to use an external
-virtual GPU device with an unmodified Cloud Hypervisor
-using <a href="https://spdk.io/news/2021/05/04/vfio-user/">vfio-user</a>
-or <a href="https://lore.kernel.org/qemu-devel/20230901110018.3704459-1-alex.bennee@linaro.org/"><code>VHOST_USER_PROTOCOL_F_PROBE</code></a>,
-or that at least the custom vhost-user commands could be standardized.
+Yes!  The <code>VHOST_USER_PROTOCOL_F_SHMEM</code> vhost-user feature
+was standardized in June 2026, meaning that non-standard vhost-user
+features are no longer required to use crosvm's GPU device.  I expect
+to propose this implementation become part of upstream Cloud
+Hypervisor shortly, once some code quality improvements are made.
