Memory aliases with different memory type is a problem for guest. For the guest without assigned device, the memory type of guest memory would always been the same as host(WB); but for the assigned device, some part of memory may be used as DMA and then set to uncacheable memory type(UC/WC), which would be a conflict of host memory type then be a potential issue. Snooping control can guarantee the cache correctness of memory go through the DMA engine of VT-d. [avi: fix build on ia64] Signed-off-by:

Shadow_mt_mask is out of date, now it have only been used as a flag to indicate if TDP enabled. Get rid of it and use tdp_enabled instead. Also put memory type logical in kvm_x86_ops->get_mt_mask(). Signed-off-by:

This moves the get_cpu() call down to be called after we wake up the waiters. Therefore the waitqueue locks can safely be rt mutex. Signed-off-by:

It just returns pending IRQ vector from the queue for VMX/SVM. Get IRQ directly from the queue before migration and put it back after. Signed-off-by:

Start to use interrupt/exception queues like VMX does. This also fix the bug that if exit was caused by a guest internal exception access to IDT the exception was not reinjected. Use EVENTINJ to inject interrupts. Use VINT only for detecting when IRQ windows is open again. EVENTINJ ensures the interrupt is injected immediately and not delayed. Signed-off-by:

Jes Sorensen authored
Make sure to restore the psr after calling kvm_insert_vmm_mapping() which calls ia64_itr_entry() as it disables local interrupts and kvm_vcpu_init() may sleep. Avoids a warning from the lock debugging code. Signed-off-by:

Matt T. Yourst notes that kvm_arch_vcpu_ioctl_set_sregs lacks validity checking for the new cr3 value: "Userspace callers of KVM_SET_SREGS can pass a bogus value of cr3 to the kernel. This will trigger a NULL pointer access in gfn_to_rmap() when userspace next tries to call KVM_RUN on the affected VCPU and kvm attempts to activate the new non-existent page table root. This happens since kvm only validates that cr3 points to a valid guest physical memory page when code *inside* the guest sets cr3. However, kvm currently trusts the userspace caller (e.g. QEMU) on the host machine to always supply a valid page table root, rather than properly validating it along with the rest of the reloaded guest state." http://sourceforge.net/tracker/?func=detail&atid=893831&aid=2687641&group_id=180599 Check for a valid cr3 address in kvm_arch_vcpu_ioctl_set_sregs, triple fault in case of failure.
