ChangeLog V2: Before sysexit, perf NMI might arrive. There is still a race. Here we change rsp to keep it pointing to pt_regs->orig_ax. In addition, after sti, before sysexit, an irq might arrives. That causes more chances for perf NMI to jump in. We hit a kernel panic when running perf to collect some performance data. kenel is x86_64 a.. 이전 1 ··· 9 10 11 12 13 14 15 다음
