csky: Add perf_arch_fetch_caller_regs support2019-04-22T05:44:57ZMao Hanhan_mao@c-sky.com2019-04-10T02:27:10Zurn:sha1:b4bf274198bd415e66af0b54a2e181c59fd43ba4
In trace events as tracepoints context are not able to
be retrieve with task_pt_regs. Without arch caller regs
support the pt_regs context will be all zero, perf can
not parsing the callchain and resolving the symbols
correctly, some time will even get into deadlock
while handling the page fault, eg:
perf kmem —page record ls
Changelog
- Add test case cmd in comment
- Use regs_fp(regs) which is defined in abi/regdef.h

csky: Add perf support for C-SKY2019-01-02T14:17:11ZGuo Renren_guo@c-sky.com2019-01-02T14:09:25Zurn:sha1:f50fd2d8524c15b08da9e7e9d84752f0f1be7172
This adds basic perf support for all C-SKY CPUs. Hardware events are
only supported by 807/810/860.
