We're having speed issues on the autobuilder due to the numbers of files in sstate directories. We previously split these by the first two characters of the hash. This change extends this to split by the next two characters as well, creating more layers of directories. This should signifiantly speed up eSDK builds on the autobuilder as the current sstate layout simply isn't scaling there but addresses a general complaint. gen-lockedsig-cache needed to be updated for the new split level sstate. Also update tests for new layout. (From OE-Core rev: d05bde16bdad761ed8f4c0a48de60c649aa33e85) 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.
