The potential performance advantages of a vmcs02 pool have never been realized. To simplify the code, eliminate the pool. Instead, a single vmcs02 is allocated per VCPU when the VCPU enters VMX operation. Signed-off-by:

This MSR returns the number of #SMIs that occurred on CPU since boot. It was seen to be used frequently by ESXi guest. Patch adds a new vcpu-arch specific var called smi_count to save the number of #SMIs which occurred on CPU since boot. It is exposed as a read-only MSR to guest (causing #GP on wrmsr) in RDMSR/WRMSR emulation code. MSR_SMI_COUNT is also added to emulated_msrs[] to make sure user-space can save/restore it for migration purposes. Signed-off-by:

If Intel/AMD implements MWAIT, we expect that it works well and only reject known bugs; no reason to do it the other way around for minor vendors. (Not that they are relevant ATM.) This allows further simplification of kvm_mwait_in_guest(). And use boot_cpu_has() instead of "cpu_has(&boot_cpu_data," while at it. Reviewed-by:

The check was added in some iteration while trying to fix a reported OS X on Core 2 bug, but that bug is elsewhere. The comment is misleading because the guest can call MWAIT with ECX = 0 even if we enforce CPUID5_ECX_INTERRUPT_BREAK; the call would have the exactly the same effect as if the host didn't have the feature. A problem is that a QEMU feature exposes CPUID5_ECX_INTERRUPT_BREAK on CPUs that do not support it. Removing the check changes behavior on last Pentium 4 lines (Presler, Dempsey, and Tulsa, which had VMX and MONITOR while missing INTERRUPT_BREAK) when running a guest OS that uses MWAIT without checking for its presence (QEMU doesn't expose MONITOR). The only known OS that ignores the MONITOR flag is old Mac OS X and we allowed it to bug on Core 2 (MWAIT used to throw #UD and only that OS noticed), so we can save another 20 lines letting it bug on even older CPUs. Alternatively, we can return MWAIT exiting by default and let userspace toggle it. Reviewed-by:

Radim Krčmář authored
The bug prevents MWAIT from waking up after a write to the monitored cache line. KVM might emulate a CPU model that shouldn't have the bug, so the guest would not employ a workaround and possibly miss wakeups. Better to avoid the situation. Reviewed-by:

UMIP can be emulated almost perfectly on Intel processor by enabling descriptor-table exits. SMSW does not cause a vmexit and hence it cannot be changed into a #GP fault, but all in all it's the most "innocuous" of the unprivileged instructions that UMIP blocks. In fact, Linux is _also_ emulating SMSW instructions on behalf of the program that executes them, because some 16-bit programs expect to use SMSW to detect vm86 mode, so this is an even smaller issue. Reviewed-by:

Paolo Bonzini authored
The User-Mode Instruction Prevention feature present in recent Intel processor prevents a group of instructions (sgdt, sidt, sldt, smsw, and str) from being executed with CPL > 0. Otherwise, a general protection fault is issued. UMIP instructions in general are also able to trigger vmexits, so we can actually emulate UMIP on older processors. This commit sets up the infrastructure so that kvm-intel.ko and kvm-amd.ko can set the UMIP feature bit for CPUID even if the feature is not actually available in hardware. Reviewed-by:

Add a line for the total number of events and current average at the bottom of the body. Note that both values exclude child trace events. I.e. if drilldown is activated via interactive command 'x', only the totals are accounted, or we'd be counting these twice (see previous commit "tools/kvm_stat: fix child trace events accounting").

Stefan Raspl authored
Child trace events were included in calculation of the overall total, which is used for calculation of the percentages of the '%Total' column. However, the parent trace envents' stats summarize the child trace events, hence we'd incorrectly account for them twice, leading to slightly wrong stats. With this fix, we use the correct total. Consequently, the sum of the child trace events' '%Total' column values is identical to the respective value of the respective parent event. However, this also means that the sum of the '%Total' column values will aggregate to more than 100 percent. Signed-off-by:

Commit 67fbcd62 ("tools/kvm_stat: add '-f help' to get the available event list") added support for '-f help'. However, the extra handling of 'help' will also take effect when 'help' is specified as a regex in interactive mode via 'f'. This results in display of all events while only those matching this regex should be shown. Signed-off-by:

When updating the fields filter, tracepoint events of fields previously not visible were not enabled, as TracepointProvider.update_fields() updated the member variable directly instead of using the setter, which triggers the event enable/disable. To reproduce, run 'kvm_stat -f kvm_exit', press 'c' to remove the filter, and notice that no add'l fields that do not match the regex 'kvm_exit' will appear. This issue was introduced by commit c469117d ("tools/kvm_stat: simplify initializers"). Signed-off-by:

When displaying debugfs events listed by guests, an attempt to switch to reporting of stats for individual child trace events results in garbled output. Reason is that when toggling drilldown, the update of the stats doesn't honor when events are displayed by guests, as indicated by Tui._display_guests. To reproduce, run 'kvm_stat -d' and press 'b' followed by 'x'. Signed-off-by:
