[pve-devel] [PATCH qemu-server/pve-manager v1 0/2] add virtio-vga-gl Vulkan (venus) support

[Markus Frank]

This option is represented by an enum in qemu-server and a comboBox in
pve-manager, with values such as 'venus-512' and 'venus-1024'. This is
to allow for the potential addition of another Vulkan implementation
in the future. The number indicates the memory window in MiB for Venus.

As I am not sure what the hostmem and blob properties actually do, I
asked on the qemu-discuss mailing list:
https://mail-archive.com/qemu-discuss@nongnu.org/msg09011.html

QEMU documentation:
www.qemu.org/docs/master/system/devices/virtio/virtio-gpu.html#virtio-gpu-virglrenderer


To get an overview of the performance, see the benchmark below.

supertuxkart (1.5) benchmark (default settings, vulkan, 1024x768):

Host result (Granite Ridge integrated GPU):
* Total frame count: 8488
* Total profiling time (ms): 38139
* Steady FPS: 92
* Mostly stable FPS: 137
* Typical FPS: 194

VM (host, 4 core, 8GiB) with venus (hostmem=8192M) result:
* Total frame count: 3321
* Total profiling time (ms): 38130
* Steady FPS: 58
* Mostly stable FPS: 75
* Typical FPS: 86

This benchmark showed no significant differences in performance between
the various memory window sizes for venus.
