Adrian Hunter e127c17af3 perf script: Fix hex dump character output ... commit 62942e9fda upstream. Using grep -C with perf script -D can give erroneous results as grep loses lines due to non-printable characters, for example, below the 0020, 0060 and 0070 lines are missing: $ perf script -D | grep -C10 AUX | head . 0010: 08 00 00 00 00 00 00 00 1f 00 00 00 00 00 00 00 ................ . 0030: 01 00 00 00 00 00 00 00 00 04 00 00 00 00 00 00 ................ . 0040: 00 08 00 00 00 00 00 00 02 00 00 00 00 00 00 00 ................ . 0050: 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 ................ . 0080: 02 00 00 00 00 00 00 00 1b 00 00 00 00 00 00 00 ................ . 0090: 00 00 00 00 00 00 00 00 ........ 0 0 0x450 [0x98]: PERF_RECORD_AUXTRACE_INFO type: 1 PMU Type 8 Time Shift 31 perf's isprint() is a custom implementation from the kernel, but the kernel's _ctype appears to include characters from Latin-1 Supplement which is not compatible with, for example, UTF-8. Fix by checking also isascii(). After: $ tools/perf/perf script -D | grep -C10 AUX | head . 0010: 08 00 00 00 00 00 00 00 1f 00 00 00 00 00 00 00 ................ . 0020: 03 84 32 2f 00 00 00 00 63 7c 4f d2 fa ff ff ff ..2/....c|O..... . 0030: 01 00 00 00 00 00 00 00 00 04 00 00 00 00 00 00 ................ . 0040: 00 08 00 00 00 00 00 00 02 00 00 00 00 00 00 00 ................ . 0050: 00 00 00 00 00 00 00 00 01 00 00 00 00 00 00 00 ................ . 0060: 00 02 00 00 00 00 00 00 00 c0 03 00 00 00 00 00 ................ . 0070: e2 00 00 00 00 00 00 00 02 00 00 00 00 00 00 00 ................ . 0080: 02 00 00 00 00 00 00 00 1b 00 00 00 00 00 00 00 ................ . 0090: 00 00 00 00 00 00 00 00 ........
