* Large page TLB flushPaul Brook2010-03-171-2/+5
| | | | | | | | | | | | | | | | | | 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>
* alpha-linux-user: Implement signals.Richard Henderson2010-02-281-78/+3
| | | | | | | | | | Move userland PALcode handling into linux-user main loop so that we can send signals from there. This also makes alpha_palcode.c system-level only, so don't build it for userland. Add defines for GENTRAP PALcall mapping to signals. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* target-alpha: Implement RD/WRUNIQUE in the translatorRichard Henderson2009-12-131-6/+5
| | | | | | | | | When emulating user-mode only, there's no reason to exit the translation block to effect a call_pal. We can generate a move to/from the unique slot directly. Signed-off-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* [PATCH] alpha: fix linux syscall conventionaurel322008-09-171-4/+5
| | | | | | | | | | | | | According to linux kernel sources, register a3 is set in case of failure (and cleared in case of success) while register v0 contains the result (or -errno in case of error). The convention was not followed which results in weird behaviour.

* Replace is_user variable with mmu_idx in softmmu core,j_mayer2007-10-141-12/+14
| | | | | | | | | | | | | | 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
