The user is asking about a bug in QEMU where calling bdrv_read in a loop leads to a "co-routine re-entered recursively" error. The code provided shows the bdrv_co_io_em function, which is a coroutine. The issue seems to be related to how coroutines are handled when the I/O completes. + +So, the problem arises when bdrv_co_io_em_complete is called from another thread before qemu_coroutine_yield is reached in bdrv_co_io_em. That would mean the coroutine is being entered again (via qemu_coroutine_enter) before the previous invocation has yielded, leading to reentrancy. + +Coroutines in QEMU are supposed to be non-preemptive and only run one at a time. If the completion callback tries to resume the coroutine before it's yielded, that's a recursion because the coroutine hasn't finished its previous execution. + +This isn't a syscall issue, nor is it an instruction error. It's more about the runtime behavior of coroutines being misused. The error happens during the execution of the coroutine code, specifically when the coroutine is re-entered before yielding. So the category should be runtime. +</think> + +runtime \ No newline at end of file |
