2010-03-17Large page TLB flushPaul Brook1-3/+4
QEMU uses a fixed page size for the CPU TLB. If the guest uses large pages then we effectively split these into multiple smaller pages, and populate the corresponding TLB entries on demand. When the guest invalidates the TLB by virtual address we must invalidate all entries covered by the large page. However the address used to invalidate the entry may not be present in the QEMU TLB, so we do not know which regions to clear. Implementing a full vaiable size TLB is hard and slow, so just keep a simple address/mask pair to record which addresses may have been mapped by large pages. If the guest invalidates this region then flush the whole TLB. Signed-off-by: Paul Brook <paul@codesourcery.com>

Disable various target specific code that is only relevant to system emulation. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-03-12Remove cpu_get_phys_page_debug from userspace emulationPaul Brook1-4/+2
cpu_get_phys_page_debug makes no sense for userspace emulation, so remove it. Signed-off-by: Paul Brook <paul@codesourcery.com>
2010-02-06target-mips: don't call cpu_loop_exit() from helper.cAurelien Jarno1-4/+4
In helper.c AREG0 may not correspond do env, so it's not possible to call cpu_loop_exit() here. Call it from op_helper.c instead. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2009-10-01Revert "Get rid of _t suffix"Anthony Liguori1-3/+3
In the very least, a change like this requires discussion on the list. The naming convention is goofy and it causes a massive merge problem. Something like this _must_ be presented on the list first so people can provide input and cope with it. This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

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
