CVSROOT: /sources/qemu Module name: qemu Changes by: Jocelyn Mayer <j_mayer> 07/10/25 21:35:50
Modified files:
. : gdbstub.c monitor.c
linux-user : main.c
target-ppc : cpu.h exec.h helper.c op.c op_helper.c
op_helper.h translate.c
Added files:
target-ppc : helper_regs.h
Log message:
Gprof prooved the PowerPC emulation spent too much time in MSR load and
store
routines. Coming back to a raw MSR storage model then speed-up the
emulation.
Improve fast MSR updates (wrtee wrteei and mtriee cases).
Share rfi family instructions helpers code to avoid bug in duplicated
code.
Allow entering halt mode as the result of a rfi instruction.
Add a new helper_regs.h file to avoid duplication of special registers
manipulation routines (currently XER and MSR).
