This commit refactors vhost-device-gpu by separating
virglrenderer from rutabaga, and using gfxstream via
rutabaga, Simplifying future backend development.
This commit introduces a significant refactor of the
virtio-gpu backend architecture:
- Transition `gfxstream` support to use `Rutabaga`
abstraction.
- Decouple `virglrenderer` from `Rutabaga`, allowing
it to be used as standalone.
- Unify backend handling using thread-local storage
and macro-based runtime dispatch.
Key Changes:
VirglRenderer Backend:
- `virgl.rs` is now a standalone backend that
directly calls `libvirglrenderer` functions.
- Removed reliance on `rutabaga` for virgl path.
Gfxstream Backend via Rutabaga:
- Introduced `gfxstream.rs` backend using `rutabaga`
- Thread-local `GfxstreamAdapter` manages its own
`Rutabaga` instance, initialized lazily.
- Preserved internal `GfxstreamResource` tracking
with scanout support and memory handling.
Renderer Selection Logic:
- In `device.rs`, `lazy_init_and_handle_event()` now:
- Dispatches `VirglRendererAdapter` and
`GfxstreamAdapter` using thread-local storage(TLS)
- Introduced `extract_backend_and_vring()` helper for
reusing backend setup logic.
Code Deduplication:
- Abstracted common logic for both backends to common.rs.
- Shared helpers reused between gfxstream and virgl.
- Improved modularity with fewer duplicated error
handling branches.
Testing and Validation:
- Replaced `virtio_gpu.rs` testing paths with new unit
tests for `gfxstream.rs` and `virgl.rs`.
- Added code coverage for the new refactored crate.
- Update coverage file to reflect the drop in coverage
due to exclusion of some gfxstream tests from CI
since they can't run in CI without GPU drivers.
