* Fix trivial "endianness bugs"Stefan Weil2011-04-031-1/+1
| | | | | | | Replace endianess -> endianness. Signed-off-by: Stefan Weil <weil@mail.berlios.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>
* target-mips: fix host CPU consumption when guest is idleAurelien Jarno2010-12-271-0/+8
| | | | | | | | | | | | | | When the CPU is in wait state, do not wake-up if an interrupt can't be taken. This avoid host CPU running at 100% if a device (e.g. timer) has an interrupt line left enabled. Also factorize code to check if interrupts are enabled in cpu_mips_hw_interrupts_pending().

| | | | | | | | | | Commit 36388314febad3d7675ab919287f03733a560ff6 moved most of the interrupt logic to cpu-exec.c. Remove the remaining useless code and fix software interrupts.

* mips: Correct MIPS interrupt glue logic for icountEdgar E. Iglesias2010-07-241-3/+0Star
| | | | | | | | | | | When hw interrupt pending bits in CP0_Cause are set, the CPU should see the hw interrupt line as active. The CPU may or may not take the interrupt based on internal state (global irq mask etc) but the glue logic shouldn't care. This fixes MIPS external hw interrupts in combination with -icount.

* target-mips: add microMIPS exception handler supportNathan Froyd2010-06-091-0/+1
| | | | | | | | | Unlike MIPS16, microMIPS lets you choose the ISA mode for your exception handlers. The ISA mode is selectable via a user-writable CP0.Config3 flag. Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* target-mips: don't call cpu_loop_exit() from helper.cAurelien Jarno2010-02-061-2/+2
| | | | | | | 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>
* target-mips: add new HFLAGs for JALX and 16/32-bit delay slotsNathan Froyd2009-12-131-19/+28
| | | | | | | | | | | | We create separate masks for the "basic" branch hflags and the "extended" branch hflags and define MIPS_HFLAG_BMASK as the logical or of those two. This is done to avoid churning the codebase in lots of different places. We also make the execution mode an hflag under MIPS_HFLAG_TMASK Signed-off-by: Nathan Froyd <froydnj@codesourcery.com> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

* target-mips: make CP0_LLAddr register CPU dependentAurelien Jarno2009-11-221-0/+2
| | | | | | | | Depending on the CPU, CP0_LLAddr is either read-only or read-write, and the returned value can be shifted by a variable amount of bits. Signed-off-by: Aurelien Jarno <aurelien@aurel32.net> Signed-off-by: Hervé Poussineau <hpoussin@reactos.org>

* Revert "Get rid of _t suffix"Anthony Liguori2009-10-011-8/+9
| | | | | | | | | | | | 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.

* cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd2009-08-241-0/+1
| | | | | | | | | | | | | | | handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.

* Refactor translation block CPU state handling (Jan Kiszka)aliguori2008-11-181-0/+8
| | | | | | | | | | | | | | | 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").
