We are always getting questions about building -stable, or mainline master. Rather than introducing a separate set of recipes, we can facilitate this sort of usecase by using the existing devupstream bbclass support. To build an unpatched or otherwise modifed -stable of 5.13, simply set the linux-yocto preferred provider to: linux-yocto-upstream and the PREFERRED_VERSION_linux-yocto-upstream to one with support. And your wish will be granted, as the build will use v5.13/base which matches the main linux-yocto version, simply with no extra changes applied.

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.
