The user is having an issue with PostgreSQL/Greenplum's spinlock getting stuck when running in a QEMU-user static environment. They provided a test case that shows the problem. The problem doesn't occur on physical ARM64 servers, so it's specific to QEMU. + +The key part here is the spinlock using a test-and-set instruction. Spinlocks often rely on atomic operations for synchronization. QEMU's user mode emulation might not be correctly handling the specific CPU instructions that implement atomic test-and-set. + +The user's test code works on actual hardware but not under QEMU. This suggests that QEMU might be incorrectly emulating the necessary atomic instructions. The PANIC errors and the lock getting stuck imply that the atomic operations aren't working as expected, leading to race conditions or incorrect memory barriers. + +Looking at the categories: instruction, syscall, runtime. The problem seems to be with the emulation of the test-and-set instruction in QEMU. Since the issue is related to a specific CPU instruction not being properly emulated, the category should be 'instruction'. It's not a syscall issue because the problem is in the atomic instruction, not system calls. Runtime is too broad here. The core issue is the instruction's incorrect emulation. +</think> + +instruction \ No newline at end of file |
