[PATCH v2 0/3] virtio-gpu: fix blob unmapping sequence

2025-04-10 Thread Manos Pitsidianakis
A hang was observed when running a small kernel that exercised VIRTIO GPU under TCG. This is an edge-case and won't happen under typical conditions. When unmapping a blob object, its MemoryRegion's freeing is deferred to the RCU thread. The hang's cause was determined to be a busy main loop no
