2008-04-07Always enable precise emulation when softfloat is usedaurel32
The patch below changes the way to enable softfloat on the PPC target. It is now enabled when softfloat is used. The rationale behind this change is that persons who want precise emulation prefer precision over emulation speed. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4168 c046a42c-6fe2-441c-8c8c-71466251a162
2008-03-13Use float32/64 instead of float/doubleaurel32
The patch below uses the float32 and float64 types instead of the float and double types in the PPC code. This doesn't change anything when using softfloat-native as the types are the same, but that helps compiling the PPC target with softfloat. It also defines a new union CPU_FloatU in addition to CPU_DoubleU, and use them instead of identical unions that are defined in numerous places. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@4047 c046a42c-6fe2-441c-8c8c-71466251a162

2007-11-16Always make PowerPC hypervisor mode memory accesses and instructionsj_mayer
available for full system emulation, then removing all #if TARGET_PPC64H from micro-ops and code translator. Add new macros to dramatically simplify memory access tables definitions in target-ppc/translate.c. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3654 c046a42c-6fe2-441c-8c8c-71466251a162
2007-11-12Allow use of SPE extension by all PowerPC targets,j_mayer
adding gprh registers to store GPR MSBs when GPRs are 32 bits. Remove not-needed-anymore ppcemb-linux-user target. Keep ppcemb-softmmu target, which provides 1kB pages support and 36 bits physical address space. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3628 c046a42c-6fe2-441c-8c8c-71466251a162

2007-11-04PowerPC 601 need specific callbacks for its BATs setup.j_mayer
Implement PowerPC 601 HID0 register, needed for little-endian mode support. As a consequence, we need to merge hflags coming from MSR with other ones. Use little-endian mode from hflags instead of MSR during code translation. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3524 c046a42c-6fe2-441c-8c8c-71466251a162

2007-10-25Gprof prooved the PowerPC emulation spent too much time in MSR load and storej_mayer
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). git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3436 c046a42c-6fe2-441c-8c8c-71466251a162

2007-10-05Full implementation of PowerPC 64 MMU, just missing support for 1 TBj_mayer
memory segments. Remove the PowerPC 64 "bridge" MMU model and implement segment registers emulation using SLB entries instead. Make SLB area size implementation dependant. Improve TLB & SLB search debug traces. Temporary hack to make PowerPC 970 boot from ROM instead of RAM. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3335 c046a42c-6fe2-441c-8c8c-71466251a162

2007-10-01Handle all MMU models in switches, even if it's just to abort because of lackj_mayer
of supporting code. Implement 74xx software TLB model. Keep 74xx with software TLB disabled, as Linux is not able to handle TLB miss on those processors. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3307 c046a42c-6fe2-441c-8c8c-71466251a162
