* KVM: Trace emulated instructionsAvi Kivity2010-05-171-0/+86
| | | | | | | Log emulated instructions in ftrace, especially if they failed. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: Trace exception injectionAvi Kivity2010-05-171-0/+32
| | | | | | Often an exception can help point out where things start to go wrong. Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: Move kvm_exit tracepoint rip reading inside tracepointAvi Kivity2010-05-171-3/+3
| | | | | | | Reading rip is expensive on vmx, so move it inside the tracepoint so we only incur the cost if tracing is enabled. Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: cleanup kvm traceXiao Guangrong2010-05-171-2/+5
| | | | | | | | | | | | This patch does: - no need call tracepoint_synchronize_unregister() when kvm module is unloaded since ftrace can handle it - cleanup ftrace's macro Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: SVM: Add kvm_nested_intercepts tracepointJoerg Roedel2010-04-251-0/+22
| | | | | | | | This patch adds a tracepoint to get information about the most important intercept bitmasks from the nested vmcb. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: SVM: Remove newlines from nested trace pointsJoerg Roedel2010-04-251-6/+6
| | | | | | | | The tracing infrastructure adds its own newlines. Remove them from the trace point printk format strings. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: Trace failed msr reads and writesAvi Kivity2010-03-011-6/+11
| | | | | | | Record failed msrs reads and writes, and the fact that they failed as well. Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: Fix msr traceAvi Kivity2010-03-011-8/+8
| | | | | | | | - data is 64 bits wide, not unsigned long - rw is confusingly named Signed-off-by: Avi Kivity <avi@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: Implement bare minimum of HYPER-V MSRsGleb Natapov2010-03-011-0/+32
| | | | | | | | | | | Minimum HYPER-V implementation should have GUEST_OS_ID, HYPERCALL and VP_INDEX MSRs. [avi: fix build on i386] Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Vadim Rozenfeld <vrozenfe@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: SVM: Add tracepoint for skinit instructionJoerg Roedel2009-12-031-0/+22
| | | | | | | | | | | This patch adds a tracepoint for the event that the guest executed the SKINIT instruction. This information is important because SKINIT is an SVM extenstion not yet implemented by nested SVM and we may need this information for debugging hypervisors that do not yet run on nested SVM. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Add tracepoint for invlpga instructionJoerg Roedel2009-12-031-0/+23
| | | | | | | | This patch adds a tracepoint for the event that the guest executed the INVLPGA instruction. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Add tracepoint for #vmexit because intr pendingJoerg Roedel2009-12-031-0/+18
| | | | | | | | | This patch adds a special tracepoint for the event that a nested #vmexit is injected because kvm wants to inject an interrupt into the guest. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Add tracepoint for injected #vmexitJoerg Roedel2009-12-031-0/+33
| | | | | | | | This patch adds a tracepoint for a nested #vmexit that gets re-injected to the guest. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Add tracepoint for nested #vmexitJoerg Roedel2009-12-031-0/+36
| | | | | | | | This patch adds a tracepoint for every #vmexit we get from a nested guest. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: SVM: Add tracepoint for nested vmrunJoerg Roedel2009-12-031-0/+33
| | | | | | | | This patch adds a dedicated kvm tracepoint for a nested vmrun. Signed-off-by: Joerg Roedel <joerg.roedel@amd.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
* KVM: Add trace points in irqchip codeGleb Natapov2009-09-101-0/+85
| | | | | | | | | Add tracepoint in msi/ioapic/pic set_irq() functions, in IPI sending and in the point where IRQ is placed into apic's IRR. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: Trace apic registers using their symbolic namesAvi Kivity2009-09-101-2/+12
| | | | Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: convert custom marker based tracing to event tracesMarcelo Tosatti2009-09-101-0/+260
This allows use of the powerful ftrace infrastructure. See Documentation/trace/ for usage information.
