2008-11-18Refactor translation block CPU state handling (Jan Kiszka)aliguori
This patch refactors the way the CPU state is handled that is associated with a TB. The basic motivation is to move more arch specific code out of generic files. Specifically the long #ifdef clutter in tb_find_fast() has to be overcome in order to avoid duplicating it for the gdb watchpoint fixes (patch "Restore pc on watchpoint hits").

2008-09-02sh4: CPU versioning.aurel32
Trivial patch adding CPU listing and the ability to do per-subtype CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are provided, as these are the ones in present use in-tree. The CVR value for SH7751R is intentionally restricted so the kernel boots, though this will want to be switched to the proper CVR value once system emulation has sufficiently stabilized. This also makes it trivial to abstract subtype specific registers like MMU_PTEA and to set up feature bits in line with the kernel probing for things like conditionalizing FPU/DSP context.

2008-08-22[sh4] memory mapped TLB entriesaurel32
SH4 MMU's memory mapped TLB feature is implemented. SH-Linux seems to write to memory mapped TLB to invalidate a TLB entry, but does not to read it. So only memory write feature is implemented. Work on memory read feature is left. (Shin-ichiro KAWASAKI) git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5067 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
