[Qemu-devel] [PATCH v1 0/2] Integrating qemu to Linux Perf

Posted by vandersonmr 4 years, 8 months ago

This patch is part of Google Summer of Code (GSoC) 2019.
More about the project can be found in:
https://wiki.qemu.org/Internships/ProjectIdeas/TCGCodeQuality

This adds --perf command-line option to dump Linux Perf 
jitdump files. These files are used to enhant Perf report
and to be able to analyze and dump JITed code with perf.

Example of use:
 perf record -k 1 qemu-x86_64 -perf ./a.out
 perf inject -j -i perf.data -o perf.data.jitted
 perf report -i perf.data.jitted
