2008-11-06target-alpha: Fix ret instructionaurel32
Hopefully pine doesn't corrupt this patch, I've had problems recently. For an alpha "ret" instruction, of the type ret $26 The return was being ignored. This is because in translate.c register $26 (the return address) was being over-written with the current PC before it could be jumped to. Thus the ret was ignored. This patch just re-orders things so the return address is processed before it is over-written with the current PC.

2008-11-05Fix windows build after init_host_timer changes.aliguori
host_alarm_timer fires in a separate thread. The windows build current uses SetEvent() and WaitEvent() to then notify the main thread. This is functionally equivalent to what we're doing in Unix with pipe(). So let's just #ifdef the pipe() code on Windows since it doesn't build there anyway.

2008-11-05Fix alarm_timer race with select - v3 (Jan Kiszka)aliguori
Changing the default IO timeout to 5 s (#5578) made a race visible between the alarm_timer and select() in main_loop_wait(): If the timer fired before select was able to block, the full select() timeout could have been applied instead of returning immediately. Since #5578, this causes heavy problems to the Musicpal board emulation with stalls up to 5 s, but also with some older Linux guest kernels. The following patch introduces a pipe that is written to by host_alarm_handler and select()'ed in main_loop_wait(). This avoids prevents that select() blocks though a timer has fired and waits for processing.

2008-11-05Add KVM support to QEMUaliguori
This patch adds very basic KVM support. KVM is a kernel module for Linux that allows userspace programs to make use of hardware virtualization support. It current supports x86 hardware virtualization using Intel VT-x or AMD-V. It also supports IA64 VT-i, PPC 440, and S390. This patch only implements the bare minimum support to get a guest booting. It has very little impact the rest of QEMU and attempts to integrate nicely with the rest of QEMU. Even though this implementation is basic, it is significantly faster than TCG. Booting and shutting down a Linux guest: w/TCG: 1:32.36 elapsed 84% CPU w/KVM: 0:31.14 elapsed 59% CPU Right now, KVM is disabled by default and must be explicitly enabled with -enable-kvm. We can enable it by default later when we have had better testing.

2008-11-04Add safety net against potential infinite loopmalc
cpu_interrupt might be called while translating the TB, but before it is linked into a potentially infinite loop and becomes env->current_tb. Currently this can (and does) cause huge problems only when using dyntick clock, with other (periodic) clocks host_alarm_handler will eventually be executed resulting in a call to cpu_interrupt which will reset the recursion of running TB and the damage is "only" latency. git-svn-id: svn://svn.savannah.nongnu.org/qemu/trunk@5620 c046a42c-6fe2-441c-8c8c-71466251a162
