On high core machines, in do_fetch, it is possible to DDoS your own machine.
A method to limit any arbitrary task type to a certain number of simultaneous
threads is needed. (Similar to how BB_NUMBER_THREADS works in the general
case.) The format of this new limitation is:
do_fetch[number_threads] = "2"
This should be set globally. If it is set in individual recipes it could
result in unpredictable behavior.
Note: a value for number_threads > BB_NUMBER_THREADS will have no effect.

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.
