2009-12-19Revert "pci: interrupt disable bit support"Anthony Liguori2-28/+2
This reverts commit 0ea5709a32085f7d14901a09d12bd35f9b267607. Per discussion with Michael Tsirkin, this is too risky for 0.12 Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> (cherry picked from commit d587e0787153f0224a6140c5015609963ceaabfb)
2009-12-19target-ppc: fix ppc32 kvm buildAlexander Graf1-0/+2
My segment sync patch broke compilation on PPC32, because it was trying to sync the SLB even though ppc32 CPUs don't have an SLB. So let's only sync it when we're on a PP64 one!

2009-12-18S390: Don't tell guest we're updating config spaceAlexander Graf1-1/+1
Currently we always set the "config space changed" bit to 1 when triggering any virtio interrupt. While that worked in 2.6.27, newer kernels interpret that value as "only the config space changed and nothing else happened". Since we usually trigger interrupts to tell the guest that something did happen, we just not tell it the config space changed for now until we implement the correct callback for that.

2009-12-18S390: Loop through virtio console devicesAlexander Graf1-1/+5

2009-12-18target-s390: Fail on unknown instructionsAlexander Graf1-1/+1
We were being a bit too nice and didn't give the guest an invalid instruction interrupt. While that works, it's not exactly the fastest thing to do, since now the guest doesn't know that we're not really implementing that instruction, so it continues doing it. We run into this with the set_page_unstable hint instruction. So let's bail out in these cases.

2009-12-18osdep: Fix runtime failure on older Linux kernelsAndre Przywara1-6/+12
If QEMU finds newer kernel header files on compilation time, it will use advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test. If later the executables are executed on an older kernel (<2.6.27, like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating pipes and returns the rather unspecific "qemu_init_main_loop failed". This patch fixes this by checking the return values of these calls for EINVAL and ENOSYS and falling back to the older versions automatically.

2009-12-13target-mips: fix user-mode emulation startupNathan Froyd2-8/+8
Running programs with the MIPS user-mode emulator fails during dynamic loading, as floating-point instructions are not enabled in in env->hflags. Move the code for doing so from fpu_init to cpu_reset so the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset setting env->hflags to MIPS_HFLAG_UM. The same end can be achieved by swapping the ordering of fpu_init and cpu_reset in cpu_mips_init, but it seemed better to consolidate the CONFIG_USER_ONLY code into a single location.

The capslock tracking logic added by commit 6b1325029d80455b9da7cd7bd84a88cb915b867c doesn't work correctly for vnc clients without EXT_KEY_EVENT support. The reason is that qemu converts keysyms for letters to lowercase for the keysym2scancode lookup. It then also passes the lowercase value down to do_key_event(), but the capslock tracking code needs it with the correct case to work properly. This patch adds a new variable for the lowercase keysym so we'll keep the unmodified value for do_key_event(). The keysym2scancode is not needed with EXT_KEY_EVENT capable clients like any app based on the gtk-vnc widget, so I missed that case in testing ...
