Patches 1-3 speed up softmmu emulation by avoiding TLB flushes on changes to IR/DR.
Patches 4-14 speed up emulation in general by rewriting the handling of condition registers. Paolo Bonzini (14): ppc: do not look at the MMU index to detect PR/HV mode softmmu: support up to 12 MMU modes target-ppc: use separate indices for various translation modes ppc: introduce ppc_get_cr and ppc_set_cr ppc: use CRF_* in fpu_helper.c ppc: introduce helpers for mfocrf/mtocrf ppc: reorganize gen_compute_fprf ppc: introduce gen_op_mfcr/gen_op_mtcr ppc: introduce ppc_get_crf and ppc_set_crf ppc: use movcond for isel ppc: store CR registers in 32 1-bit registers ppc: use movcond to implement evsel ppc: inline ppc_get_crf/ppc_set_crf when clearer ppc: dump all 32 CR bits include/exec/cpu_ldst.h | 120 ++++++++- linux-user/elfload.c | 4 +- linux-user/main.c | 9 +- linux-user/signal.c | 8 +- monitor.c | 9 +- target-ppc/cpu.h | 66 ++++- target-ppc/excp_helper.c | 5 +- target-ppc/fpu_helper.c | 82 +++--- target-ppc/gdbstub.c | 42 +-- target-ppc/helper.h | 9 +- target-ppc/helper_regs.h | 11 +- target-ppc/int_helper.c | 46 +++- target-ppc/kvm.c | 11 +- target-ppc/machine.c | 9 + target-ppc/translate.c | 686 ++++++++++++++++++++++++----------------------- 15 files changed, 631 insertions(+), 486 deletions(-) -- 1.8.3.1
