* virtio-gpu: support context init multiple timelineYiwei Zhang2025-07-021-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Venus and later native contexts have their own fence context along with multiple timelines within. Fences wtih VIRTIO_GPU_FLAG_INFO_RING_IDX in the flags must be dispatched to be created on the target context. Fence signaling also has to be handled on the specific timeline within that target context. Before this change, venus fencing is completely broken if the host driver doesn't support implicit fencing with external memory objects. Frames can go backwards along with random artifacts on screen if the host driver doesn't attach an implicit fence to the render target. The symptom could be hidden by certain guest wsi backend that waits on a venus native VkFence object for the actual payload with limited present modes or under special configs. e.g. x11 mailbox or xwayland. After this change, everything related to venus fencing starts making sense. Confirmed this via guest and host side perfetto tracing.

* hw/display: fix virgl reset regressionMarc-André Lureau2021-07-221-2/+6
| | | | | | | | | | | | | | | | | | Before commit 49afbca3b00e8e517d54964229a794b51768deaf ("virtio-gpu: drop use_virgl_renderer"), use_virgl_renderer was preventing calling GL functions from non-GL context threads. The innocuously looking g->parent_obj.use_virgl_renderer = false; was set the first time virtio_gpu_gl_reset() was called, during pc_machine_reset() in the main thread. Further virtio_gpu_gl_reset() calls in IO threads, without associated GL context, were thus skipping GL calls and avoided warnings or crashes (see also https://gitlab.freedesktop.org/virgl/virglrenderer/-/issues/226).
