2011-01-12KVM: x86: Makefile clean upTracey Dent
Changed makefile to use the ccflags-y option instead of EXTRA_CFLAGS. Signed-off-by: Tracey Dent <tdent48227@gmail.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2011-01-12KVM: Halt vcpu if page it tries to access is swapped outGleb Natapov
If a guest accesses swapped out memory do not swap it in from vcpu thread context. Schedule work to do swapping and put vcpu into halted state instead. Interrupts will still be delivered to the guest and if interrupt will cause reschedule guest will continue to run another task.

2009-09-10KVM: Rename x86_emulate.c to emulate.cAvi Kivity
We're in arch/x86, what could we possibly be emulating? Signed-off-by: Avi Kivity <avi@redhat.com>
2009-09-10KVM: remove old KVMTRACE support codeMarcelo Tosatti
Return EOPNOTSUPP for KVM_TRACE_ENABLE/PAUSE/DISABLE ioctls. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-09-10KVM: convert custom marker based tracing to event tracesMarcelo Tosatti
This allows use of the powerful ftrace infrastructure. See Documentation/trace/ for usage information.

2009-09-10KVM: irqfdGregory Haskins
KVM provides a complete virtual system environment for guests, including support for injecting interrupts modeled after the real exception/interrupt facilities present on the native platform (such as the IDT on x86). Virtual interrupts can come from a variety of sources (emulated devices, pass-through devices, etc) but all must be injected to the guest via the KVM infrastructure. This patch adds a new mechanism to inject a specific interrupt to a guest using a decoupled eventfd mechnanism: Any legal signal on the irqfd (using eventfd semantics from either userspace or kernel) will translate into an injected interrupt in the guest at the next available interrupt window.

2009-09-10KVM: cleanup arch/x86/kvm/MakefileChristoph Hellwig
Use proper foo-y style list additions to cleanup all the conditionals, move module selection after compound object selection and remove the superflous comment. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Avi Kivity <avi@redhat.com>
2009-06-10KVM: unify part of generic timer handlingMarcelo Tosatti
Hide the internals of vcpu awakening / injection from the in-kernel emulated timers. This makes future changes in this logic easier and decreases the distance to more generic timer handling. Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2009-01-03KVM: rename vtd.c to iommu.cJoerg Roedel
Impact: file renamed The code in the vtd.c file can be reused for other IOMMUs as well. So rename it to make it clear that it handle more than VT-d. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
2008-10-15KVM: Separate irq ack notification out of arch/x86/kvm/irq.cXiantao Zhang

2008-10-15KVM: Device Assignment with VT-dBen-Ami Yassour
Based on a patch by: Kay, Allen M <allen.m.kay@intel.com> This patch enables PCI device assignment based on VT-d support. When a device is assigned to the guest, the guest memory is pinned and the mapping is updated in the VT-d IOMMU.
