The user provided a bug where qemu-img hangs on rcu_call_ready_event logic in Aarch64 when converting images. They mentioned it's happening on a HiSilicon D06 system with 96 cores. + +Looking at the backtrace, the issue seems related to the main loop waiting and poll functions. The stack trace goes through ppoll, qemu_poll_ns, os_host_main_loop_wait, main_loop_wait, convert_do_copy, img_convert, and main. This suggests that the problem is happening during the conversion process in qemu-img. + +The key part here is that it's hanging on rcu_call_ready_event logic. RCU stands for Read-Copy-Update, which is a synchronization mechanism used in multi-threaded environments to handle updates while allowing reads to proceed without blocking. Issues with RCU can lead to hangs or deadlocks if not handled correctly. + +Given the categories provided: mistranslation, assembly, other, device, graphic, socket, network, KVM, boot, vnc, debug, files, permissions, performance, kernel, peripherals, hypervisor. + +Since this is related to concurrency and synchronization in QEMU's main loop during an image conversion process, it doesn't fit into the usual categories like network or device issues. It also isn't directly about translation, assembly, or user-mode specifics beyond what's already handled. + +Looking closer, RCU is part of the kernel's internal mechanisms for handling concurrent data structures. In QEMU, which can act as a hypervisor and manage multiple virtual machines, proper handling of such synchronization primitives is crucial. If the hang is due to improper use or a bug in how RCU is being called or handled, it would fall under the 'kernel' category because it's related to the underlying system calls and concurrency management. + +So, putting it all together, the issue is with kernel-level operations, specifically involving RCU, which affects QEMU's main loop during image conversion. Therefore, the appropriate category should be 'kernel'. +</think> + +kernel \ No newline at end of file |
