The coroutine implementation in ruby has either arch specific implementations or it falls back to slower ucontext API based implementation assuming libc will provide the needed APIs, however musl does not implement ucontext APIs like glibc, therefore fallback is to use libucontext library on musl. However, libucontext is not ported to riscv yet. which means on musl/riscv ruby is unbuildable, however a third option is to use copy implementation for coroutines, which will be not as good performance-wise, but it will do the job, therefore for now use copy implementation for rv32/rv64 when using musl (From OE-Core rev: 3b2b401dbbb8d3aa14a5fd864178f702af3c8115) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
