KVM: s390: more irq names for trace events

2015-07-29T09:02:34+00:00

This patch adds names for missing irq types to the trace events.
In order to identify adapter irqs, the define is moved from
interrupt.c to the other basic irq defines in uapi/linux/kvm.h.

kvm/x86: add sending hyper-v crash notification to user space

2015-07-23T06:27:06+00:00

Sending of notification is done by exiting vcpu to user space
if KVM_REQ_HV_CRASH is enabled for vcpu. At exit to user space
the kvm_run structure contains system_event with type
KVM_SYSTEM_EVENT_CRASH to notify about guest crash occurred.

KVM: arm64: guest debug, HW assisted debug support

2015-07-21T11:50:43+00:00

This adds support for userspace to control the HW debug registers for
guest debug. In the debug ioctl we copy an IMPDEF registers into a new
register set called host_debug_state.

We use the recently introduced vcpu parameter debug_ptr to select which
register set is copied into the real registers when world switch occurs.

I've made some helper functions from hw_breakpoint.c more widely
available for re-use.

As with single step we need to tweak the guest registers to enable the
exceptions so we need to save and restore those bits.

Two new capabilities have been added to the KVM_EXTENSION ioctl to allow
userspace to query the number of hardware break and watch points
available on the host hardware.

KVM: add comments for kvm_debug_exit_arch struct

2015-07-21T11:47:08+00:00

Bring into line with the comments for the other structures and their
KVM_EXIT_* cases. Also update api.txt to reflect use in kvm_run
documentation.

- The usual pile of GIC fixes
- PSCI fixes
- Random cleanups

kvm: remove one useless check extension

2015-06-17T08:46:28+00:00

We already check KVM_CAP_IRQFD in generic once enable CONFIG_HAVE_KVM_IRQFD,

kvm_vm_ioctl_check_extension_generic()
    |
    + switch (arg) {
    +   ...
    +   #ifdef CONFIG_HAVE_KVM_IRQFD
    +       case KVM_CAP_IRQFD:
    +   #endif
    +   ...
    +   return 1;
    +   ...
    + }
    |
    + kvm_vm_ioctl_check_extension()

So its not necessary to check this in arch again, and also fix one typo,
s/emlation/emulation.

KVM: implement multiple address spaces

2015-06-05T15:26:35+00:00

Only two ioctls have to be modified; the address space id is
placed in the higher 16 bits of their slot id argument.

As of this patch, no architecture defines more than one
address space; x86 will be the first.

KVM: x86: API changes for SMM support

2015-06-04T14:01:11+00:00

This patch includes changes to the external API for SMM support.
Userspace can predicate the availability of the new fields and
ioctls on a new capability, KVM_CAP_X86_SMM, which is added at the end
of the patch series.

KVM: x86: Support for disabling quirks

2015-05-07T09:29:42+00:00

Introducing KVM_CAP_DISABLE_QUIRKS for disabling x86 quirks that were previous
created in order to overcome QEMU issues. Those issue were mostly result of
invalid VM BIOS.  Currently there are two quirks that can be disabled:

1. KVM_QUIRK_LINT0_REENABLED - LINT0 was enabled after boot
2. KVM_QUIRK_CD_NW_CLEARED - CD and NW are cleared after boot

These two issues are already resolved in recent releases of QEMU, and would
therefore be disabled by QEMU.
