Hi,
I'm working on Virtio GPU drivers for AmigaOS, and would like to know
what features are currently stable enough to use. Looking at the master
QEMU branch, both Virgl and blob resources are supported, but NOT at the
same time. Is the ability to use both simultaneously coming soon?
Mmh, well, they should be compatible, I'll try sending a patch.
Also, what's the state of Venus/Vulkan support? Surveying various
forks/branches, it looks very experimental and subject to change.
I believe this is quite stable now:

Virglrenderer 1.0.0 has been released as well. I wonder if that requires
any change in QEMU. Gert or Dmitry might know the answer.
I have the added difficulty that the AmigaOS Picasso96 driver API
expects direct CPU access to all of VRAM, and likes to peek/poke
directly into the bitmaps. That's clearly not possible without blob
resources, or shared memory (not entirely sure what the shared memory
feature is for). This is why I want to know what features are stable or
coming soon.
The shared memory feature is just a requirement which enables support
for blob resources.

Hans
