Hi Michael, Alex, Dmitry, Akihiko,
I'm bringing AMD GPU compute ROCm based on virtio. I posted a ROCm over
virtio
implementation to virglrenderer nine months ago (MR !1568 [1]). The ROCm
side has
been supportted by ROCm offical.
Current implementation is a virtio gpu context type capset handled inside
virglrenderer, sharing the display path. That's an awkward fit, many
compute GPUs have no display engine at all.
The headless context type is totally fine with virtio-gpu. For example,
ChoromeOS wirh crosvm disables display entirely even on guest side by
building virtio-gpu kernel driver without KMS support. This is something
to improve in QEMU to make it work without GL context.
Thanks for the inforamtion.
It's great to know that headless contexts are fine and that ChromeOS
already has a working model for this. The changes to the ROCM native
context from QEMU are not much, maybe we can leverage the changes made
from ChromeOS to assist ROCm.
Regaeds,
Honglei
