2007-11-17PowerPC hypervisor mode is not fundamentally available only for PowerPC 64.j_mayer
Remove TARGET_PPC64 dependency and add code provision to be able to define a fake 32 bits CPU with hypervisor feature support. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3678 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

2007-11-11Optimize PowerPC overflow flag computation in most useful cases.j_mayer
Use the same routines to check overflow for addo, subfo and PowerPC 405 multiply and add cases. Fix carry reset in addme(o) and subfme(o) cases. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3574 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
2007-11-03PowerPC MMU and exception fixes:j_mayer
* PowerPC 601 (and probably POWER/POWER2) uses a different BAT format than later PowerPC implementation. * Bugfix in BATs check: must not stop after 4 BATs when more are provided. * Enable POWER 'rac' instruction. * Fix exception prefix for all supported PowerPC implementations. * Fix exceptions, MMU model and bus model for PowerPC 601 & 620. * Enable PowerPC 620 as it could mostly boot a PreP target. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3518 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

2007-10-14Replace is_user variable with mmu_idx in softmmu core,j_mayer
allowing support of more than 2 mmu access modes. Add backward compatibility is_user variable in targets code when needed. Implement per target cpu_mmu_index function, avoiding duplicated code and #ifdef TARGET_xxx in softmmu core functions. Implement per target mmu modes definitions. As an example, add PowerPC hypervisor mode definition and Alpha executive and kernel modes definitions. Optimize PowerPC case, precomputing mmu_idx when MSR register changes and using the same definition in code translation code. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@3384 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

2007-09-29Rework PowerPC exceptions model to make it more versatile:j_mayer
* don't use exception vectors as the exception number.
