2013-04-12Check effective suspension of TCG threadOlivier Hainque
On multi-core systems, SuspendThread does not guaranty immediate thread suspension. We add busy loop to wait for effective thread suspension after call to ThreadSuspend().

2013-03-12cpu: Pass CPUState to cpu_interrupt()Andreas Färber
Move it to qom/cpu.h to avoid issues with include order. Change pc_acpi_smi_interrupt() opaque to X86CPU. Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-03-12cpus: Replace open-coded CPU loop in qmp_memsave() with qemu_get_cpu()Andreas Färber
No functional change, just less usages of first_cpu and next_cpu fields. env is passed to cpu_memory_rw_debug(), which in turn passes it to target-specific cpu_get_phys_page_debug(). Changing both would be a larger refactoring, so defer that by using env_ptr for now. Reviewed-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Andreas Färber <afaerber@suse.de>
2013-02-16cpus.c: Drop unnecessary set_cpu_log()Peter Maydell
The set_cpu_log() function in cpus.c is a fairly simple wrapper which is only called from one location. Just inline the code into vl.c, since there is no need to indirect it via cpus.c and the handling of the error case is more appropriate to vl.c.

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 Maydell
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 Vinod
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 test frameworkAnthony Liguori
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.
