Mesa's Venus Vulkan Driver Updated To Allow QEMU Support

([Virtualization] 6 Hours Ago Venus Driver + QEMU)


Mesa's Venus Vulkan driver has made cross-device functionality optional in order to enable QEMU support for this open-source driver for virtualized environments.

Dmitry Osipenko of Collabora authored the [1]merge request to relax the requirements around cross-device functionality so that this Venus driver can work under QEMU. Osipenko explained in the patch:

Cross-device is a virtio-gpu feature that enables sharing host blob dma-bufs with other virtio devices, like virtio-wl or virtio-video. This feature is mainly used by ChromeOS and not required if there is no dma-buf sharing. Venus has a hard requirement for the cross-device feature.

Qemu doesn't support cross-device. Relax cross-device feature requirement by making it optional, allowing Venus to work on Qemu.

Mesa's [2]Venus driver is a VirtIO-GPU protocol for Vulkan command serialization that works with the Virglrenderer. This change will be part of next quarter's Mesa 24.2 release.

Bill Gates Receives Slap On Wrist; Carpal Tunnel Flares Up

The phrase "slap on the wrist" usually signifies an extremely minor
punishment received for a crime. In Bill Gates' case, the punishment set
forth in the tentative settlement with the Department Of Justice hasn't
been quite so minor. After receiving a slap on the wrist from the DOJ,
Bill Gates' is now suffering from a bad case of carpal tunnel syndrome.

"Mr. Gates was slapped on the left wrist earlier today by a DOJ lawyer,"
said the chief surgeon of the mini-hospital enclosed within the Gates
Mansion. "Now he can't move that hand without extreme pain. It's obvious
that years of sitting in front of a computer plotting world domination has
caused his hands and nerves to become fragile and vulnerable to even the
slightest touch."

The Department of Justice proclaimed that the incident has vindicated
their actions. Explained the lawyer who delivered the punishment, "We've
been accused of selling out to Microsoft. We've been criticized for giving
up even though we've already won the game. But that's all wrong. It's
quite clear that the slap-on-the-wrist punishment has been anything but a
slap on the wrist. We won this case and Microsoft lost. So there!"
