2007-09-30Implement the PowerPC alternate time-base, following the 2.04 specification.j_mayer
Share most code with the time-base management routines. Remove time-base write routines from user-mode emulation environments. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3277 c046a42c-6fe2-441c-8c8c-71466251a162
2007-09-29PowerPC emulation optimization:j_mayer
avoid stopping translation after most SPR updates when a context-synchronization instruction is also needed. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3265 c046a42c-6fe2-441c-8c8c-71466251a162
2007-09-29Rework PowerPC exceptions model to make it more versatile:j_mayer
* don't use exception vectors as the exception number. Use vectors numbers as defined in the PowerPC embedded specification instead and extend this model to cover all emulated PowerPC variants exceptions. * add some missing exceptions definitions, from PowerPC 2.04 specification and actual PowerPC implementations. * add code provision for hypervisor exceptions handling. * define exception vectors and prefix in CPUPPCState to emulate BookE exception vectors without any hacks. * define per CPU model valid exception vectors. * handle all known exceptions in user-mode only emulations. * fix hardware interrupts priorities in most cases. * change RET_EXCP macros name into GEN_EXCP as they don't return. * do not stop translation on most instructions that are not defined as context-synchronizing in PowerPC specification. * fix PowerPC 64 jump targets and link register update when in 32 bits mode. * Fix PowerPC 464 and 464F definitions. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3261 c046a42c-6fe2-441c-8c8c-71466251a162
