If a recipe applies patches which are in machine-specific override directories, devtool will fail to fetch the patches that don't match the default configuration. For example where there are patches at qemux86/x86.patch and qemuarm/arm.patch: SRC_URI = "file://source" SRC_URI_append_qemuarm = " file://arm.patch" SRC_URI_append_qemux86 = " file://x86.patch" The patch apply phase sets OVERRIDES but does not set FILESOVERRIDES, so it cannot find the patch files as the search path isn't correct. Fix this by setting FILESOVERRIDES too. Also when iterating through the overrides we need to be sure that other overrides that are used are not enabled, so extend no_overrides instead of simply appending the current override. Fixes most but not all of [ YOCTO #14060 ].

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.
