Hi
Here are some patches that add support for reading object code from vmlinux, kernel modules and /proc/kcore.
Changes in V4: perf tools: make it possible to read object code from kernel modules Fix symbol adjustment for kernel modules Remove kallsyms' symbols when using a module's symbols perf tools: add kcore to the object code reading test Do not use static variables perf tools: put dso name in symbol annotation title New patch perf tools: remove nop at end of annotation New patch perf tools: add annotation call target name if it is missing New Patch
Changes in V3: perf tools: adjust the vmlinux symtab matches kallsyms test again New patch perf tools: add test for reading object code Fix error path by removing unnecessary perf_evlist__disable() Fix error path by setting evlist to NULL after deletion Fix sampling frequency by changing from 40000 to 4000 Increase the number of operations performed by the "workload" to compensate for the lower sampling frequency
Changes in V2: Re-based on Arnaldo's tree's perf/core branch
perf tools: add test for reading object code Use strchr in read_objdump_line() Remove unused return value of read_objdump_line() Fix double space before "cycles:u" Add missing perf_evlist__delete(evlist) in do_test_code_reading() perf tools: load kernel maps before using Correct spelling of "initialization" in commit message perf tools: add support for reading from /proc/kcore Do not test kallsyms filename for host buildid because /proc/kallsyms is always used if the dso buildid matches the host perf tools: add kcore to the object code reading test Remove redundant "else if (!have_kcore && try_kcore)" clause
Adrian Hunter (13): perf tools: add test for reading object code perf tools: load kernel maps before using perf tools: make it possible to read object code from vmlinux perf tools: adjust the vmlinux symtab matches kallsyms test perf tools: avoid SyS kernel syscall aliases perf tools: make it possible to read object code from kernel modules perf tools: add support for reading from /proc/kcore perf tools: adjust the vmlinux symtab matches kallsyms test again perf tools: add kcore to the object code reading test perf tools: allow annotation using /proc/kcore perf tools: put dso name in symbol annotation title perf tools: remove nop at end of annotation perf tools: add annotation call target name if it is missing
