Hello, I'm trying to use perf-probe(1) with the latest F14 kernel (2.6.35.9-64.fc14.x86_64).
I also installed kernel-debug-debuginfo-2.6.35.9-64.fc14.x86_64 which contains the running vmlinux image AFAICT. I added it to the buildid cache: $ perf buildid-cache -v -a /usr/lib/debug/lib/modules/2.6.35.9-64.fc14.x86_64.debug/vmlinux Adding 4d89e23415d8ab491cfc8ef8aa67764b91cc6787 /usr/lib/debug/lib/modules/2.6.35.9-64.fc14.x86_64.debug/vmlinux: OK But when running perf-probe(1) like the following: $ perf probe schedule cpu Failed to find path of kernel moduleFailed to open debuginfo file. Error: Failed to add events. (-2) it fails. One strange thing is that when perf read the running kernel build id, it get: 882b1b53eb1d65320e8fa710273aa8493896c4. Could anybody tell me what I'm doing wrong ?
