commit ae7a0d81e9f4e1804b11116ea05adab73e5118bd Author: ouyangxiangzhen <[email protected]> AuthorDate: Thu Jul 10 11:05:42 2025 +0800 testing/drivers: Fix posix timer assertions. On QEMU, if vcpus are preempted by other threads, the deviation of the timer might be very large, causing assertion failure. This commit addressed the problem.
