2009-08-24cleanup cpu-exec.c, part 0/N: consolidate handle_cpu_signalNathan Froyd
handle_cpu_signal is very nearly copy-paste code for each target, with a few minor variations. This patch sets up appropriate defaults for a generic handle_cpu_signal and provides overrides for particular targets that did things differently. Fixing things like the persistent (XXX: use sigsetjmp) should now become somewhat easier. Previous comments on this patch suggest that the "activate soft MMU for this block" comments refer to defunct functionality. I have removed such blocks for the appropriate targets in this patch.

2009-08-24unify popen/fopen qemu wrappersPaolo Bonzini
While reading Chris's code for fd migration I noticed the duplication between QEMUFilePopen and QEMUFileStdio. This fixes it, and makes qemu_fopen more similar qemu_popen. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-24Unbreak large mem support by removing kqemuAnthony Liguori
kqemu introduces a number of restrictions on the i386 target. The worst is that it prevents large memory from working in the default build. Furthermore, kqemu is fundamentally flawed in a number of ways. It relies on the TSC as a time source which will not be reliable on a multiple processor system in userspace. Since most modern processors are multicore, this severely limits the utility of kqemu. kvm is a viable alternative for people looking to accelerate qemu and has the benefit of being supported by the upstream Linux kernel. If someone can implement work arounds to remove the restrictions introduced by kqemu, I'm happy to avoid and/or revert this patch. N.B. kqemu will still function in the 0.11 series but this patch removes it from the 0.12 series. Paul, please Ack or Nack this patch. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-24Migration via unix sockets.Chris Lalancette
Implement migration via unix sockets. While you can fake this using exec and netcat, this involves forking another process and is generally not very nice. By doing this directly in qemu, we can avoid the copy through the external nc command. This is useful for implementations (such as libvirt) that want to do "secure" migration; we pipe the data on the sending side into the unix socket, libvirt picks it up, encrypts it, and transports it, and then on the remote side libvirt decrypts it, dumps it to another unix socket, and feeds it into qemu. The implementation is straightforward and looks very similar to migration-exec.c and migration-tcp.c Signed-off-by: Chris Lalancette <clalance@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-24Route IOAPIC interrupts via ISA busAvi Kivity
Instead of calling the IOAPIC from the PIC, raise IOAPIC irqs via the ISA bus. As a side effect, IOAPIC lines 16-23 are enabled. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-24Route PC irqs to ISA bus instead of i8259 directlyAvi Kivity
A PC has its motherboard IRQ lines connected to both the PIC and IOAPIC. Currently, qemu routes IRQs to the PIC which then calls the IOAPIC, an incestuous arrangement. In order to clean this up, create a new ISA IRQ abstraction, and have devices raise ISA IRQs (which in turn raise the i8259 IRQs as usual).

2009-08-24QEMU set irq0override in fw_cfgJes Sorensen
Hi, After discussing the issue with Avi, Gleb and a couple others on irq, we came to the conclusion that it is preferred to have QEMU request features from the BIOS, rather than notifying the BIOS that it is running on QEMU or KVM. This way memory ranges can change etc. and an older BIOS will continue to work on newer QEMU if it receives the info as a fw_cfg value. This one also matches what qemu-kvm does for irq0override, except I haven't made it configurable. I leave that as an exercise for whoever would be interested in switching off irq0override. Thanks, Jes Set irq0 override in fw_cfg, informing the BIOS that QEMU expects override on irq0. This matches qemu-kvm, and will help sharing a single BIOS binary.

2009-08-24Fix detached migration with exec.Chris Lalancette
When trying to do detached migration with exec, I found that the monitor wouldn't always return in a timely manner. I tracked this down to exec_start_outgoing_migration. It appeared we were setting the fd to NONBLOCK'ing, but in point of fact we weren't.

2009-08-24make vga screen_dump use DisplayState properlyStefano Stabellini
Hi all, currently the vga screen_dump code doesn't use the DisplayState interface properly and tries to replace it temporarily while taking the screenshot. A better approach is to register a DisplayChangeListener, call vga_hw_update, and finally write the ppm in the next call from dpy_update. Testing is appreciated.

2009-08-23sdl.c: support 32 bpp cursorsReimar Döffinger
Hello, currently when a 32 bpp cursor gets defined the result is all-black in the areas that are not transparent (you'll get a 32 bpp cursor if you use my previous patch to allow vmware_vga to use a 32 bpp framebuffer). This is because the switch in sdl.c lacks a 32 bpp case. The thing I am unsure about though is which byte is the unused one and should be skipped, the first or the last - for the black-and-white cursors I tested it doesn't make a difference...

2009-08-23Use corect depth from DisplaySurface in vmware_vga.cReimar Döffinger
Hello, for what I can tell, there is no way for vmware_vga to work correctly right now. It assumes that the framebuffer bits-per-pixel and the one from the DisplaySurface are identical (it uses directly the VRAM from vga.c), but it always assumes 3 bytes per pixel, which is never possible with the current version of DisplaySurface. Attached patch fixes that by using ds_get_bits_per_pixel.
