| * When -icount is used and a TB is recompiled due to an IO access pbrook2008-12-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | shortly after an IRQ has been raised, env->exception_index will still be set to EXCP_IRQ when cpu_io_recompile calls cpu_resume_from_signal. This causes qemu to repeat the IRQ trap, with disasterous consequences. I suspect this "works" most of the time because linux tends to drop back to svc mode before doing actual IRQ processing, and be fairly tolerant of spurious IRQ traps.

| * target-i386: SVM: acknowledge interrupt only after it is takenaurel322008-12-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SVM specifies that the V_IRQ mask is only to be removed, if the interrupt that is to be delivered actually is delivered. As of the SVM rewrite, this mask is always unmasked when the main cpu loop is processed, leaving a corner case where calling the interrupt handler causes a #PF. In that case (booting Linux / starting gfxboot) the current implementation tells the VMM the interrupt is taken, even though it is not. This patch modifies the VIRQ unmasking to occur after do_interrupt, making gfxboot work again.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Fix interrupt exclusion via SSTEP_NOIRQmalc2008-11-061-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit #5620 revealed an issue of the SSTEP_NOIRQ masking that was applied on all interrupt sources (including internal ones) when single stepping through the guest. Due to that commit, we now ended up in an infinite loop when CPU_INTERRUPT_EXIT was pending on SSTEP resume. That was due to #5620 eating all TBs while CPU_INTERRUPT_EXIT is pending, but SSTEP_NOIRQ preventing CPU_INTERRUPT_EXIT to be processed. What SSTEP_NOIRQ should actually do is to block the delivery of all external, guest visible interrupts. With the fix below applied, single stepping now works again.

| * Add KVM support to QEMUaliguori2008-11-051-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * Add safety net against potential infinite loopmalc2008-11-041-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | 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
