Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being x86-specific flags to being generic ones. This allows us to drop some TARGET_I386 ifdefs in various places, and means that we can (potentially) be more consistent across architectures about which monitor commands or debug abort printouts include FPU register contents and info about QEMU's condition-code optimisations.

2012-08-09kvm: Decouple 'async interrupt delivery' from 'kernel irqchip'Peter Maydell1-1/+2
On x86 userspace delivers interrupts to the kernel asynchronously (and therefore VCPU idle management is done in the kernel) if and only if there is an in-kernel irqchip. On other architectures this isn't necessarily true (they may always send interrupts asynchronously), so define a new kvm_async_interrupts_enabled() function instead of misusing kvm_irqchip_in_kernel().

2012-08-04Fixes related to processing of qemu's -numa optionChegu Vinod1-1/+2
The -numa option to qemu is used to create [fake] numa nodes and expose them to the guest OS instance. There are a couple of issues with the -numa option: a) Max VCPU's that can be specified for a guest while using the qemu's -numa option is 64. Due to a typecasting issue when the number of VCPUs is > 32 the VCPUs don't show up under the specified [fake] numa nodes. b) KVM currently has support for 160VCPUs per guest. The qemu's -numa option has only support for upto 64VCPUs per guest. This patch addresses these two issues. Below are examples of (a) and (b) a) >32 VCPUs are specified with the -numa option: /usr/local/bin/qemu-system-x86_64 \ -enable-kvm \ 71:01:01 \ -net tap,ifname=tap0,script=no,downscript=no \ -vnc :4 ...

2012-03-30qtest: add clock managementPaolo Bonzini1-0/+20

2012-03-30qtest: add test frameworkAnthony Liguori1-3/+59
The idea behind qtest is pretty simple. Instead of executing a CPU via TCG or KVM, rely on an external process to send events to the device model that the CPU would normally generate. qtest presents itself as an accelerator. In addition, a new option is added to establish a qtest server (-qtest) that takes a character device. This is what allows the external process to send CPU events to the device model. qtest uses a simple line based protocol to send the events. Documentation of that protocol is in qtest.c. I considered reusing the monitor for this job. Adding interrupts would be a bit difficult. In addition, logging would also be difficult. qtest has extensive logging support. All protocol commands are logged with time stamps using a new command line option (-qtest-log). Logging is important since ultimately, this is a feature for debugging.

2012-01-19apic: Inject external NMI events via LINT1Jan Kiszka1-1/+5

E.g. kdump expect this wiring and gets upset if the per-APIC LINT1 mask is not respected, i.e. if NMIs are injected to VCPUs that should not receive them.
