| |
Changlog: There are some changes from David Ahern's review: - let the tool to be off-box analysis by getting cpu isa from HEADER_CPUID feature and removing max-vcpu related code.
- attach per vcpu record structure to the thread by adding a void pointer in "struct thread".
- remove unnecessary tool argument(-v).
The output example is following: # ./perf kvm-events report --event mmio --vcpu 3 Warning: Error: expected type 5 but read 4 Warning: Error: expected type 5 but read 0 Warning: unknown op '}'
Analyze events for VCPU 3:
