Hi All,
I have fixed both the issue with perf test.
1) 16: Try 'import perf' in python, checking link problems : FAILED! To fix this issue, I have to install: pip install --upgrade pip pip2.7 install perf
2) 37.2: Test BPF prologue generation : FAILED! To fix this issue I had to enable full version of CONFIG_DEBUG_INFO in kernel.
Now, my question is: Is it possible to pass BPF test without enabling CONFIG_DEBUG_INFO in kernel ?
It depends on what BPF test does, but it seems to access local vars. This means you need to enable CONFIG_DEBUG_INFO. With debuginfo we can find the assignment of register/stack for each local variable.
OK. Thank you so much for your reply. I think we don't need BPF test at this time. Is it possible to disable/skip it ?
It depends on what you want to do with perf. If you don't use BPF, yes, you can skip it :)
Yes I want to skip the BPF. What is the best way to skip it. I found out that by commenting 'bpf' under : tools/build/Makefile.feature -> FEATURE_TESTS_BASIC, I can turn BPF feature OFF during compilation. However, I still need to execute BPF test and check, if it skips. Is this good enough ?
Thank you,
