Question about latency tracer output

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello!

What's the meaning of VP and KP, as in the log exerpt bellow? I saw that
they are hardcoded to 0... are they just placeholders?

    [root@dexterlab ~]# cat /proc/latency_trace
    preemption latency trace v1.1.5 on 2.6.21-rc3-rt0
    --------------------------------------------------------------------
    latency: 65 us, #20/20, CPU#3 | (M:rt VP:0, KP:0, SP:1 HP:1 #P:4)

Thanks,
Luis
