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.

2008-10-24Fix windows build after migration changesaliguori
The live migration code broke the windows build. As part of this change, I've switched the BIOS path to C:\Program Files\Qemu instead of /c/Program Files/Qemu. The later is only valid when launching from MSYS but the former is always valid.

2008-10-08Fix IO performance regression in sparcaliguori
Replace signalfd with signal handler/pipe. There is no way to interrupt the CPU execution loop when a file descriptor becomes readable. This results in a large performance regression in sparc emulation during bootup. This patch switches us to signal handler/pipe which was originally suggested by Ian Jackson. The signal handler lets us interrupt the CPU emulation loop while the write to a pipe lets us avoid the select/signal race condition.

2008-10-07Add sparse checker support to the build system (Gerd Hoffman)aliguori
This adds support for running the sparse checker during the build process. Left it off by default for now, build becomes very noisy with sparse checking turned on as it has to complain alot (partly even in the system headers!). The qemu code base needs quite some cleanups before we should consider turning it on by default.

2008-09-30Avoid (some) ppc cross-compilation problemsmalc
[..snip..] A recent kvm merge with qemu brought code for 64bit power that broke cross compilation. The issue is caused by configure trying to execute target architecture binaries where configure is executed.

2008-09-27Make compatfd fallback more robustaliguori
Be more friendly when signalfd() fails, and also add configure checks to detect that syscall(SYS_signalfd) actually works. malc pointed out that some installs do not have /usr/include/linux headers that are in sync with the glibc headers so why SYS_signalfd is defined, it's #defined to _NR_signalfd which is not defined in the /usr/include/linux header. While this is a distro bug, it doesn't hurt to do a more thorough job in detection.

2008-09-26Fix build on FreeBSDaliguori
__GLIBC_PREREQ is defined in such a way that the ! cannot be used in front of it on FreeBSD. Also, -lpthread is not implied by the build and we definitely use it for compatfd support. While at it, I added a default initialization for posix-aio that seems to perform well in our testing.

2008-09-11Only build compatfd when using AIO and make sure to always init AIOaliguori
OpenBSD doesn't use AIO so don't try to build compatfd when not using AIO. Also make sure to call qemu_aio_init() from bdrv_init. Everything that uses bdrv calls bdrv_init so it makes sense to init aio from there instead of in every single tool.

2008-08-21Fix windows buildaliguori
Right now, the Windows build is broken because of NBD. Using a mingw32 cross compiler is also badly broken. This patch fixes the Windows build by stubbing out NBD support until someone fixes it for Windows. It also santizing the mingw32 cross compiler support by replacing the --enable-mingw32 option with a compiler check to determine if we're on windows or not. Also remove the weird SDL pseudo-detection for mingw32 using a cross compiler. The hardcoded sdl-config name is seemly arbitrary. If you cross compiler SDL correctly and modify your PATH variable appropriately, it will Just Work when cross compiling. The audio driver detection is also broken for cross compiling so you have to specify the audio drivers explicitly for now.
