[PATCH v1 2/2] perf/kvm: perf-kvm-stat to report syscalls
From: Hemant Kumar
Date: Fri Feb 27 2015 - 04:44:34 EST
Some of the kvm_hv exits are due to hcalls. So, this patch adds necessary
support to display the number of hcalls grouped according to their type
(H_IPI, H_CONFER, etc) with "perf kvm stat report --event=syscall".
The patch defines the reasons in "kvm_trace_symbol_hcall". It adds
kvm_hv:kvm_hcall_enter tracepoint to be recorded when
"perf kvm stat record" is invoked. It defines the handler functions to
handle a kvm_hcall_enter event sample from the samples recorded in
perf.data.guest.
To reuse the pSeries hypervisor opcodes, they codes are removed from
arch/powerpc/include/asm/hvcall.h and added to a new .h file in
arch/powerpc/include/uapi/asm/hcall_codes.h.
Also the hcall_code to hcall_reason string mapping is removed from
arch/powerpc/kvm/trace_hv.h to a new file
arch/powerpc/include/uapi/asm/trace_hcall.h
so that perf in the userspace can use them.
A sample output :
# pgrep qemu
19378
60515
# ./perf kvm stat record -a
^C[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 4.153 MB perf.data.guest (39624 samples) ]
# ./perf kvm stat report -p 60515 --event=syscall
Analyze events for pid(s) 60515, all VCPUs:
SYSCALL-EVENT Samples Samples% Time% Min Time Max Time Avg time
H_VIO_SIGNAL 1034 38.44% 15.77% 0.36us 1.59us 0.44us ( +- 0.66% )
H_SEND_CRQ 652 24.24% 10.97% 0.39us 1.84us 0.49us ( +- 1.20% )
H_IPI 523 19.44% 62.05% 1.35us 19.70us 3.44us ( +- 2.88% )
H_PUT_TERM_CHAR 411 15.28% 8.03% 0.38us 3.77us 0.57us ( +- 1.61% )
H_GET_TERM_CHAR 50 1.86% 0.99% 0.40us 0.98us 0.57us ( +- 3.37% )
H_EOI 20 0.74% 2.19% 2.22us 4.72us 3.17us ( +- 5.96% )
Total Samples:2690, Total events handled time:2896.94us.
