This program reads a trace file that contains trace output from the BPF VM,
and generates a profile for tools like callgrind_annotate or QCacheGrind.
To resolve names of functions this program may require a dump file containing the instruction dump of the ELF.
You can create the dump file by passing --dump flag to cargo-build-bpf.
You can create the trace file by running the Solana cluster under RUST_LOG:
export RUST_LOG=solana_bpf_loader_program=trace
Use the bpf-profile help generate command to list available options.
When the trace file is ready, use the following command:
bpf-profile generate <trace file path> -d <dump file path> -o callgrind.out
which should produce new file callgrind.out containing the profile data.
It can be read by any standard tool for analysis.
This program expects input files created with Solana 1.6.x. Other versions of Solana may generate incompatible data.
