* Darwin: Check for x86_64 only on i386malc2009-02-231-3/+3
| | | | | | | | | | The sysctl variable if we're 64-bit capable only exists on i386. So we should only check it if we're on i386. This suppresses a warning on PowerPC spotted by Andreas Faerber.

* Enabled building of x86_64 code on Mac OS X (Alexander Graf)aliguori2009-01-261-1/+11
| | | | | | | | | | | | | | | Mac OS X 10.5 supports 64-bit userspace on an x86_64 kernel and by default uses 32-bit userspace applications, so the detection for the host architecture fails. This patch enabled building of x86_64 code on x86_64 capable CPUS with Mac OS X.

* report issues causing the kvm probe to fail (Christian Ehrhardt)aliguori2009-01-151-7/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch applies to upstream qemu as well as kvm-userspace, but since it is the qemu configure script I think it should go to upstream qemu (Anthony) first and with the next merge to kvm-userspace. On the other hand it is the kvm probe so an ack from Avi in case v3 is ok would be reasonable. *updates* v2 - it also reports other errors than just #error preprocessor statements (requested by Avi) v3 - In case awk or grep is not installed it now gracfully (silently) fails still disabling kvm (requested by Anthony) This patch is about reporting more details of the issue if configuring kvm fails. Therefore this patch keeps the qemu style configure output which is a list of "$Feature $Status", but extend the "no" result like "KVM Support no" with some more information. There might be a lot of things going wrong with that probe and I don't want to handle all of them, but if it is one of the known checks e.g. for KVM_API_VERSION then we could grep/awk that out and report it. The patch reports in case of a known case in the style "KVM support no - (Missing KVM capability KVM_CAP_DESTROY_MEMORY_REGION_WORKS)" In case more than one #error is triggered it creates a comma separated list in those brackets and in case it is something else than an #error it just reports plain old "no".

* fix configuring kvm probe when using --kerneldir (Christian Ehrhardt)aliguori2009-01-091-0/+6
| | | | | | | | | | | | | | | | | | | | There is already a variable kvm_cflags which gets the path of the kernel includes when using --kerneldir. But eventually with newer kernels we all will need arch/$arch/include too (my case was a incldue of asm/kvm.h which was not found anymore). Headers in a full kernel source are not flattened to one arch like they are if e.g. installed kernel headers are used. To fix that, the includes added to cflags depending on --kerneldir should also contian the arch includes. The patch adds a special check for x86 because its source layout recently changed, all others directly use arch/$cpu/include if existent.

* Parse --cc and --cross-prefix earlier and use CC to determine cpu and hostaliguori2008-12-291-33/+59
| | | | | | | | | | | | | | | | | | | | | We have been relying on uname to determine the host cpu architecture and operating system. This is totally broken for cross compilation. It was workable in the past because you can manually override both settings but after the host USB passthrough refactoring, cross host builds were broken. This moves the parsing of --cc and --cross-prefix to before the probes for cpu and host. Complation testing is used to determine the host and CPU types. I've only added checks for i386, x86_64, Linux, and Windows since these are the only platforms I have access to for testing. Everything else falls back to uname. It should be relatively easy to add the right checks for other platforms and eliminate uname altogether.

* Replace posix-aio with custom thread poolaliguori2008-12-121-15/+5Star
| | | | | | | | | | | | | | | | | | | | | | | | | | glibc implements posix-aio as a thread pool and imposes a number of limitations. 1) it limits one request per-file descriptor. we hack around this by dup()'ing file descriptors which is hideously ugly 2) it's impossible to add new interfaces and we need a vectored read/write operation to properly support a zero-copy API. What has been suggested to me by glibc folks, is to implement whatever new interfaces we want and then it can eventually be proposed for standardization. This requires that we implement our own posix-aio implementation though. This patch implements posix-aio using pthreads. It immediately eliminates the need for fd pooling. It performs at least as well as the current posix-aio code (in some circumstances, even better).

* Add KVM support to QEMUaliguori2008-11-051-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
