[PATCH V4 11/13] perf script: Add support for PERF_SAMPLE_CODE_PAGE_SIZE
From: kan . liang
Date: Thu Jan 31 2019 - 15:29:13 EST
From: Stephane Eranian <eranian@xxxxxxxxxx>
Add a new perf script filter called code_page_size. There will be more
than 32 filters. Extend the enum perf_output_field from U to UL.
Display sampled code page sizes when PERF_SAMPLE_CODE_PAGE_SIZE was set.
For example,
perf script --fields comm,event,ip,code_page_size
dtlb mem-loads:uP: 445777 4K
dtlb mem-loads:uP: 40f724 4K
dtlb mem-loads:uP: 474926 4K
dtlb mem-loads:uP: 401075 4K
dtlb mem-loads:uP: 401095 4K
dtlb mem-loads:uP: 401095 4K
dtlb mem-loads:uP: 4010cc 4K
dtlb mem-loads:uP: 440b6f 4K
