2009-10-10CRIS: Segmented addressing only for kernel mode.Edgar E. Iglesias1-1/+1

2009-01-15Clean up debugging code #ifdefs (Eduardo Habkost)aliguori1-6/+6
Use macros to avoid #ifdefs on debugging code. This patch doesn't try to merge logging macros from different files, but just unify the debugging code #ifdefs onto a macro on each file. A further cleanup can unify the debugging macros on a common header, later Signed-off-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@6332 c046a42c-6fe2-441c-8c8c-71466251a162

2007-10-14Replace is_user variable with mmu_idx in softmmu core,j_mayer1-1/+2
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
