Obsoleted by the vmx-specific per-cpu list. Signed-off-by: NAvi Kivity <avi@qumranet.com>
-
由 Avi Kivity 提交于
VMX hardware can cache the contents of a vcpu's vmcs. This cache needs to be flushed when migrating a vcpu to another cpu, or (which is the case that interests us here) when disabling hardware virtualization on a cpu. The current implementation of decaching iterates over the list of all vcpus, picks the ones that are potentially cached on the cpu that is being offlined, and flushes the cache. The problem is that it uses mutex_trylock() to gain exclusive access to the vcpu, which fires off a (benign) warning about using the mutex in an interrupt context. To avoid this, and to make things generally nicer, add a new per-cpu list of potentially cached vcus. This makes the decaching code much simpler. The list is vmx-specific since other hardware doesn't have this issue.

KVM turns off hardware virtualization extensions during reboot, in order to disassociate the memory used by the virtualization extensions from the processor, and in order to have the system in a consistent state. Unfortunately virtual machines may still be running while this goes on, and once virtualization extensions are turned off, any virtulization instruction will #UD on execution. Fix by adding an exception handler to virtualization instructions; if we get an exception during reboot, we simply spin waiting for the reset to complete. If it's a true exception, BUG() so we can have our stack trace. Signed-off-by: NAvi Kivity <avi@qumranet.com>

The KVM MMU tries to detect when a speculative pte update is not actually used by demand fault, by checking the accessed bit of the shadow pte. If the shadow pte has not been accessed, we deem that page table flooded and remove the shadow page table, allowing further pte updates to proceed without emulation. However, if the pte itself points at a page table and only used for write operations, the accessed bit will never be set since all access will happen through the emulator. This is exactly what happens with kscand on old (2.4.x) HIGHMEM kernels. The kernel points a kmap_atomic() pte at a page table, and then proceeds with read-modify-write operations to look at the dirty and accessed bits. We get a false flood trigger on the kmap ptes, which results in the mmu spending all its time setting up and tearing down shadows. Fix by setting the shadow accessed bit on emulated accesses.

由 Chris Lalancette 提交于
Attached is a patch that fixes a guest crash when booting older Linux kernels. The problem stems from the fact that we are currently emulating MSR_K7_EVNTSEL[0-3], but not emulating MSR_K7_PERFCTR[0-3]. Because of this, setup_k7_watchdog() in the Linux kernel receives a GPF when it attempts to write into MSR_K7_PERFCTR, which causes an OOPs. The patch fixes it by just "fake" emulating the appropriate MSRs, throwing away the data in the process. This causes the NMI watchdog to not actually work, but it's not such a big deal in a virtualized environment. When we get a write to one of these counters, we printk_ratelimit() a warning. I decided to print it out for all writes, even if the data is 0; it doesn't seem to make sense to me to special case when data == 0. Tested by myself on a RHEL-4 guest, and Joerg Roedel on a Windows XP 64-bit guest. Signed-off-by: NChris Lalancette <clalance@redhat.com> Signed-off-by: NAvi Kivity <avi@qumranet.com>

The in-kernel PIT emulation ignores pending timers if operating under mode 3, which for example Hurd uses. This mode should output a square wave, high for (N+1)/2 counts and low for (N-1)/2 counts. As we only care about the resulting interrupts, the period is N, and mode 3 is the same as mode 2 with regard to interrupts.
