does anyone understand how to effectively use buildstats to set BB_PRESSURE_MAX_*? I'm looking at pybootchartgui.py drawing of buildstats and still not sure what value to use (for measuring build time benefit with test-oe-build-time)
<JaMa>
hmm maybe I'm missing that graph, because my buildstats dir doesn't have cpu.log and io.log files, probably because I don't have /proc/pressure/, will investigate a bit more
<JaMa>
in kernel you need PSI "Pressure stall information tracking" and psi kernel param is needed when PSI_DEFAULT_DISABLED "Require boot parameter to enable pressure stall information tracking" is enabled as well, if it was mentioned in the buildstats commit/discussion I've overlooked it
