Re: [yocto-autobuilder-helper][PATCH] config.json: track system load with PARALLEL_MAKE
Alexander Kanavin
I seem to vaguely remember that -l is not actually taking a percentage, but an absolute value that is specific to the amount of CPU cores a system has. Have you verified your assumption?

This adds the "-l" option to PARALLEL_MAKE in config.json with an
initial testing value of 100 (100% system load). This option is supported
by both Make and Ninja. However, we also require the "--debug=j" option
to be passed to Make in order for the latter to report perceived system
load in the do_compile logs, and since this option is not supported by
Ninja, also add EXTRA_OEMAKE to the EXTRAVARS so that we can determine if
the target load percentage needs to be adjusted.
