* kvm: Add kvm_has_pit_state2 helperJan Kiszka2012-03-071-0/+5
| | | | | | | To be used for in-kernel PIT emulation. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* kvm: Implement kvm_irqchip_in_kernel like kvm_enabledJan Kiszka2012-02-081-5/+0
| | | | | | | | | | To both avoid that kvm_irqchip_in_kernel always has to be paired with kvm_enabled and that the former ends up in a function call, implement it like the latter. This means keeping the state in a global variable and defining kvm_irqchip_in_kernel as a preprocessor macro.

* kvm: x86: Establish IRQ0 override controlJan Kiszka2012-01-191-0/+5
| | | | | | | | KVM is forced to disable the IRQ0 override when we run with in-kernel irqchip but without IRQ routing support of the kernel. Set the fwcfg value correspondingly. This aligns us with qemu-kvm. Signed-off-by: Jan Kiszka <jan.kiszka@siemens.com>
* Remove exec-all.h include directivesBlue Swirl2011-06-261-1/+1

* kvm: Clean up stubsJan Kiszka2011-06-201-17/+1
| | | | | | | | | | | No one references kvm_check_extension, kvm_has_vcpu_events, and kvm_has_robust_singlestep outside KVM code. kvm_update_guest_debug is never called, thus has no job besides returning an error.

* Remove unused sysemu.h include directivesBlue Swirl2011-04-151-1/+0

* Introduce log_start/log_stop in CPUPhysMemoryClientAnthony PERARD2011-02-141-10/+0
| | | | | | | | | | | | | | | In order to use log_start/log_stop with Xen as well in the vga code, this two operations have been put in CPUPhysMemoryClient. The two new functions cpu_physical_log_start,cpu_physical_log_stop are used in hw/vga.c and replace the kvm_log_start/stop. With this, vga does no longer depends on kvm header.

* kvm: Provide sigbus services arch-independentlyJan Kiszka2011-02-141-0/+5
| | | | | | | | | | | Provide arch-independent kvm_on_sigbus* stubs to remove the #ifdef'ery from cpus.c. This patch also fixes --disable-kvm build by providing the missing kvm_on_sigbus_vcpu kvm-stub.

* kvm: test for ioeventfd support on old kernelsStefan Hajnoczi2011-01-101-0/+5
| | | | | | | | | | | There used to be a limit of 6 KVM io bus devices in the kernel. On such a kernel, we can't use many ioeventfds for host notification since the limit is reached too easily. Add an API to test for this condition. Signed-off-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
* MCE: Relay UCR MCE to guestMarcelo Tosatti2010-10-201-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Port qemu-kvm's commit 4b62fff1101a7ad77553147717a8bd3bf79df7ef Author: Huang Ying <ying.huang@intel.com> Date: Mon Sep 21 10:43:25 2009 +0800 MCE: Relay UCR MCE to guest UCR (uncorrected recovery) MCE is supported in recent Intel CPUs, where some hardware error such as some memory error can be reported without PCC (processor context corrupted). To recover from such MCE, the corresponding memory will be unmapped, and all processes accessing the memory will be killed via SIGBUS. For KVM, if QEMU/KVM is killed, all guest processes will be killed too. So we relay SIGBUS from host OS to guest system via a UCR MCE injection. Then guest OS can isolate corresponding memory and kill necessary guest processes only. SIGBUS sent to main thread (not VCPU threads) will be broadcast to all VCPU threads as UCR MCE. aliguori: fix build Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

This allows limited use of kvm functions (which will return ENOSYS) even in once-compiled modules. The patch also improves a bit the error messages for KVM initialization.
