我想進入PAPI。我在Debian GNU/Linux上安裝了5.3.2版本。 papi_avail只是告訴我,沒有硬件事件提供:papi_avail:沒有可用的活動

我找不到文檔中任何東西,也不在FAQ。有人知道這裏有什麼問題嗎?

我剛剛有同樣的問題。就我而言,這是一個過於偏執內核標誌:

 
root@*****:/home/*****# ./papi/src/utils/papi_component_avail 
Available components and hardware information. 
-------------------------------------------------------------------------------- 
[...] 

Compiled-in components: 

Name: perf_event    Linux perf_event CPU counters 
    \-> Disabled: perf_event support disabled by Linux with paranoid=3 
Name: perf_event_uncore  Linux perf_event CPU uncore and northbridge 

Active components: 
Name: perf_event_uncore  Linux perf_event CPU uncore and northbridge 
           Native: 2, Preset: 0, Counters: 3 
           PMUs supported: rapl 

我的perf_event_paranoid理解是,它並不適用於根,但顯然值3是不同的。

不知道原來的問題是否屬於這種情況,因爲3似乎是在2016年添加的,但由於這是人們現在可能會問的問題,所以我希望這會有所幫助。

這個固定:

sudo sh -c 'echo -1 >/proc/sys/kernel/perf_event_paranoid'

注意這並開闢了專櫃給大家,這是在我的情況很好。
