Let's start by understanding what the user is reporting. + +The issue occurs when running PostgreSQL/Greenplum inside a Docker container using qemu-user-static. The problem seems to be with spinlocks causing the system to panic because they get stuck. The test code provided shows that the lock value isn't being released correctly, leading to timeouts and failures. + +Looking at the code snippets from s_lock.h and s_lock.c, it's related to how spinlocks are implemented. In the test case (spinlock_qemu.c), the program initializes a lock variable and uses atomic operations to set and clear it. The output shows that after certain operations, the lock value remains 1, leading to timeouts. + +The user mentions that this works fine on physical ARM64 servers but fails under QEMU. This suggests an issue with how QEMU emulates the ARM64 instructions, specifically the test-and-set (tas) instruction used in spinlocks. + +In QEMU's context, the 'qemu-user' component is responsible for translating user-mode code from one architecture to another. Since this bug occurs during user-mode execution and involves incorrect behavior of atomic operations (like TAS), it likely falls under the mistranslation category. This would mean that the translation between the source (x86_64) and target (ARM64) architectures isn't handling some instructions correctly. + +Other categories like 'device' or 'network' don't seem relevant here since the issue is specific to atomic operations, not hardware devices or network-related functions. The problem is purely in how QEMU handles CPU instructions at the user level, so it's not a kernel, hypervisor, or performance issue either. + +Therefore, the bug report points to an incorrect mapping of the TAS instruction during translation, which directly relates to mistranslation. +</think> + +mistranslation \ No newline at end of file |
