HPerf reads a Linux perf trace (perf.data) and annotates the corresponding disassembly. This is similar to
perf-annotate, but with a GUI, a different layout, and additional features.
perf record -b.
hperf command reads a
perf.data trace file and outputs a single self-contained
HPerf is well suited for long perf traces, but may be slow with large binaries. This is because it will get from
objdump the full disassembly of all the DSOs encountered in the trace, and all of it needs to fit in memory. Trace samples are then counted against their corresponding instruction, allowing for arbitrarily long traces. Note that the output will contain the disassembly of all hotspots (plus some context) and the content of all corresponding source files.
Usage: hperf [options] Options: -i file input file, produced by perf-record (default: perf.data) -o file output file (default: report.html) -s count[%%] minimum number of samples per insn (default: 1) -t count[%%] minimum total number of samples per hotspot (default: 2) -c n merge hotspots separated by up to n insn (default: 5) -d n output n insn before and after hotspots (default: 100) -T theme 'dark', 'light' or css file path (default: light)
