Latest iteration of rutabaga_gfx + gfxstream patches. Previous version
and more background available here:
https://patchew.org/QEMU/20230421011223.718-1-gurchetansi...@chromium.org/
Changes since RFC:
- All important memory tests pass
- Went with separate virtio-gpu-rutabaga device as suggested by Bernard
Berschow
- Incorporated review feedback, mostly from Akihiko Odaki
- gfxstream has new unified guest/host repo + build system improvements
- added documentation on virtio-gpu
- new instructions on how to build available in the tracking bug [a]
In terms of API stability/versioning/packaging, once this series is
reviewed, the plan is to cut a "gfxstream upstream release branch". We
will have the same API guarantees as any other QEMU project then, i.e no
breaking API changes for 5 years.
The Android Emulator will build both gfxstream (to get bug fixes fast)
and QEMU8.0+ (due to regulatory requirements) from sources. So we haven't
created a gfxstream Debian/Ubuntu package since we actually don't need it.
Though, we plan to upload our QEMU8.0+ gfxstream enabled builds somewhere
on AOSP when it's ready.
It's more important for us to be in-tree to reduce technical debt given
this. Let us know if there are any strong opinions on packaging.
Otherwise, feedback + reviews welcome!
