Adds another flag bit (bit 2) to MSR_KVM_ASYNC_PF_EN. If bit 2 is 1, async page faults are delivered to L1 as #PF vmexits; if bit 2 is 0, kvm_can_do_async_pf returns 0 if in guest mode. This is similar to what svm.c wanted to do all along, but it is only enabled for Linux as L1 hypervisor. Foreign hypervisors must never receive async page faults as vmexits, because they'd probably be very confused about that.

There is a flaw in the Hyper-V SynIC implementation in KVM: when message page or event flags page is enabled by setting the corresponding msr, KVM zeroes it out. This is problematic because on migration the corresponding MSRs are loaded on the destination, so the content of those pages is lost. This went unnoticed so far because the only user of those pages was in-KVM hyperv synic timers, which could continue working despite that zeroing. Newer QEMU uses those pages for Hyper-V VMBus implementation, and zeroing them breaks the migration. Besides, in newer QEMU the content of those pages is fully managed by QEMU, so zeroing them is undesirable even when writing the MSRs from the guest side. To support this new scheme, introduce a new capability, KVM_CAP_HYPERV_SYNIC2, which, when enabled, makes sure that the synic pages aren't zeroed out in KVM.

The backwards_tsc_observed global introduced in commit 16a96021 is never reset to false. If a VM happens to be running while the host is suspended (a common source of the TSC jumping backwards), master clock will never be enabled again for any VM. In contrast, if no VM is running while the host is suspended, master clock is unaffected. This is inconsistent and unnecessarily strict. Let's track the backwards_tsc_observed variable separately and let each VM start with a clean slate. Real world impact: My Windows VMs get slower after my laptop undergoes a suspend/resume cycle. The only way to get the perf back is unloading and reloading the kvm module. Signed-off-by: NLadi Prosek <lprosek@redhat.com> Signed-off-by: NRadim Krčmář <rkrcmar@redhat.com>

This patch adds a few lines to the KVM common code to fire a KOBJ_CHANGE uevent whenever a KVM VM is created or destroyed. The event carries five environment variables: CREATED indicates how many times a new VM has been created. It is useful for example to trigger specific actions when the first VM is started COUNT indicates how many VMs are currently active. This can be used for logging or monitoring purposes PID has the pid of the KVM process that has been started or stopped. This can be used to perform process-specific tuning. STATS_PATH contains the path in debugfs to the directory with all the runtime statistics for this VM. This is useful for performance monitoring and profiling. EVENT described the type of event, its value can be either "create" or "destroy" Specific udev rules can be then set up in userspace to deal with the creation or destruction of VMs as needed.

由 Radim Krčmář 提交于
kvm master clock usually has a different frequency than the kernel boot clock. This is not a problem until the master clock is updated; update uses the current kernel boot clock to compute new kvm clock, which erases any kvm clock cycles that might have built up due to frequency difference over a long period. KVM_SET_CLOCK is one of places where we can safely update master clock as the guest-visible clock is going to be shifted anyway. The problem with current code is that it updates the kvm master clock after updating the offset. If the master clock was enabled before calling KVM_SET_CLOCK, then it might have built up a significant delta from kernel boot clock. In the worst case, the time set by userspace would be shifted by so much that it couldn't have been set at any point during KVM_SET_CLOCK. To fix this, move kvm_gen_update_masterclock() before computing kvmclock_offset, which means that the master clock and kernel boot clock will be sufficiently close together. Another solution would be to replace get_kvmclock_ns() with "ktime_get_boot_ns() + ka->kvmclock_offset", which is marginally more accurate, but would break symmetry with KVM_GET_CLOCK.
