There are a number of timeout and hang defects where
it would be useful to collect statistics about what
is running on a build host when that condition occurs.
This adds functionality to collect build system stats
on a regular interval and/or on task failure. Both
features are disabled by default.
To enable logging on a regular interval, set:
BB_HEARTBEAT_EVENT = "<interval>"
BB_LOG_HOST_STAT_ON_INTERVAL = <boolean>
Logs are stored in ${BUILDSTATS_BASE}/<build_name>/host_stats
To enable logging on a task failure, set:
BB_LOG_HOST_STAT_ON_FAILURE = "<boolean>"
Logs are stored in ${BUILDSTATS_BASE}/<build_name>/build_stats
The list of commands, along with the desired options, need
to be specified in the BB_LOG_HOST_STAT_CMDS variable
delimited by ; as such:
BB_LOG_HOST_STAT_CMDS = "command1 ; command2 ;... ;"

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
