oe-time-dd-test records how much time it takes to write <count> number of kilobytes to the filesystem. It also records the number of processes that are in running (R), uninterruptible sleep (D) and interruptible sleep (S) state from the output of "top" command. The purporse of this script is to find which part of the build system puts stress on the filesystem io and log all the processes.

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.
