In order to improve performance of qemumips autobuilder test runs, let's use 34Kf-64tlb cpu type that was introduced in OE version of qemu. 34Kf-64tlb cpu type is identical to 34Kf but it has 64 TLBs configure vs original 16 TLBs. The change in number of TLBs in emulated CPU reduces TLB trash and reduces number of times TLB refill kernel code runs, and therefore siginificantly improves tests execution time. Note 34Kf-64tlb qemu cpu type does not exist in upstream, so far it is added as patch in OE. See qemu 34Kf-64tlb cpu addition commit for more details.

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.
