2009-08-27allow overriding of CPUID level on command lineAndre Przywara
The CPUID level determines how many CPUID leafs are exposed to the guest. Some features (like multi-core) cannot be propagated without the proper level, but guests maybe confused by bogus entries in some leafs. So add level= and xlevel= to the list of -cpu options to allow the user to override the default settings. While at it, merge unnecessary local variables into one and allow hexadecimal arguments.

2009-08-27set CPUID bits to present cores and threads topologyAndre Przywara
Controlled by the enhanced -smp option set the CPUID bits to present the guest the desired topology. This is vendor specific, but (with the exception of the CMP_LEGACY bit) not conflicting, so we set all bits everytime. There is no real multithreading support for AMD CPUs, so report cores instead.

2009-08-27push CPUID level to 4 to allow Intel multicore decodingAndre Przywara
Intel CPUs store the number of cores in CPUID leaf 4. So push the maxleaf value to 4 to allow the guests access to this leaf. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2009-08-27extend -smp parsing to include cores= and threads= optionsAndre Przywara
For injecting multi-core and multi-threading CPU topology into guests extend the -smp syntax to accommodate cores and threads specification. Syntax: -smp smp_value[,cores=nr_cores][,threads=nr_threads]\ [,socket=nr_sockets][,maxcpus=max_cpus] smp_value is the legacy value specifying the total number of vCPUs for the guest. If you specify one of cores, threads or sockets this value can be omitted. Missing values will be computed to fulfill: smp_value = nr_cores * nr_threads * nr_sockets where it will favour sockets over cores over threads (to mimic the current behavior, which will only inject multiple sockets.) So -smp 4,threads=2 will inject two sockets with 2 threads each, -smp cores=4 is an abbreviation for -smp 4,cores=4,threads=1,sockets=1. If max_cpus (the number of hotpluggable CPUs) is omitted, it will be set to smp_value. Signed-off-by: Andre Przywara <andre.przywara@amd.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2009-08-25Sparc32: improve interrupt handlingBlue Swirl
Level 15 interrupts are broadcast to all CPUs, each CPU can clear the interrupt using the local Clear Pending register. Update intbit_to_level table. Don't try to raise level 0 interrupts. Calculate pending interrupts based on the separate inputs from master register. Setting or resetting the pending level isn't correct because of overlap of levels. Level 14 is always used for CPU timer interrupts, remove the property. Signed-off-by: Blue Swirl <blauwirbel@gmail.com>

2009-08-25target-mips: fix conditional moves off fp condition codesNathan Froyd
Conditional moves off fp condition codes were using the result of get_fp_bit to isolate and test the relevant condition code. However, get_fp_bit returns the bit number of the condition code, not a bitmask. (Compare the use of get_fp_bit in gen_compute_branch1, for instance.) Fixed by shifting a bitmask into place using the result of get_fp_bit in the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

2009-08-24Make the e1000 the default network adapter for the pc target.Anthony Liguori
The ne2k is an ancient card that performs pretty terribly under QEMU. In many modern OSes, there is no longer drivers available for the ne2k. Switch the default network adapter to e1000. This card is more widely suppported and performs rather well under QEMU. There may be very old OSes that had a ne2k driver but not an e1000 driver but I think this is likely the exception. I think the average user is better served with an e1000 vs ne2k. Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

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.

2009-08-24Unbreak 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 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.
