Subject: perf script: Print raw ip instead of binary offset for callchain
X-Git-Tag: v6.6.7~2868^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0e20f4311254193fbf9eebafb4dc5c922a885397;p=platform%2Fkernel%2Flinux-starfive.git

perf script: Print raw ip instead of binary offset for callchain

Before this, the raw ip is printed for non-callchain and dso offset for
callchain. This inconsistent output for address may confuse people. And
mostly what we expect is the raw ip.

'dso offset' is printed in callchain:

  $ perf script
  ...
  ls 1341034 2739463.008343:    2162417 cycles:
          ffffffff99d657a7 [unknown] ([unknown])
          ffffffff99e00b67 [unknown] ([unknown])
                     235d3 memset+0x53 (/usr/lib/x86_64-linux-gnu/ld-2.31.so)  # dso offset
                      a61b _dl_map_object+0x1bb (/usr/lib/x86_64-linux-gnu/ld-2.31.so)

raw ip is printed for non-callchain:

  $ perf script  -G
  	...
          ls 1341034 2739463.008876:    2053304 cycles:  ffffffffc1596923 [unknown] ([unknown])
          ls 1341034 2739463.009381:    1917049 cycles:      14def8e149e6 __strcoll_l+0xd96 (/usr/lib/x86_64-linux-gnu/libc-2.31.so) # raw ip

Let's have consistent output for it. Later I'll add a new field 'dsoff' to
print dso offset.
