util/cbfstool: Add cbfs-compression-tool
cbfs-compression-tool provides a way to benchmark the compression algorithms as used by cbfstool (and coreboot) and allows to pre-compress data for later consumption by cbfstool (once it supports the format). For an impression, the benchmark's results on my machine: measuring 'none' compressing 10485760 bytes to 10485760 took 0 seconds measuring 'LZMA' compressing 10485760 bytes to 1736 took 2 seconds measuring 'LZ4' compressing 10485760 bytes to 41880 took 0 seconds And a possible use for external compression, parallel and non-parallel (60MB in 53 files compressed to 650KB on a machine with 40 threads): $ time (ls -1 *.* |xargs -n 1 -P $(nproc) -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA) real 0m0.786s user 0m11.440s sys 0m0.044s $ time (ls -1 *.* |xargs -n 1 -P 1 -I '{}' cbfs-compression-tool compress '{}' out/'{}' LZMA) real 0m10.444s user 0m10.280s sys 0m0.064s Change-Id: I40be087e85d09a895b1ed277270350ab65a4d6d4 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: https://review.coreboot.org/18099 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com>
