2018-05-19perf annotate: Create hotkey 'c' to show min/max cyclesJin Yao
In the 'perf annotate' view, a new hotkey 'c' is created for showing the min/max cycles. For example, when press 'c', the annotate view is: Percent│ IPC Cycle(min/max) │ │ │ Disassembly of section .text: │ │ 000000000003aab0 <random@@GLIBC_2.2.5>: 8.22 │3.92 sub $0x18,%rsp │3.92 mov $0x1,%esi │3.92 xor %eax,%eax │3.92 cmpl $0x0,argp_program_version_hook@@G │3.92 1(2/1) ↓ je 20 │ lock cmpxchg %esi,__abort_msg@@GLIBC_P │ ↓ jne 29 │ ↓ jmp 43 │1.10 20: cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+ 8.93 │1.10 1(5/1) ↓ je 43 When press 'c' again, the annotate view is switched back: Percent│ IPC Cycle │ │ │ Disassembly of section .text: │ │ 000000000003aab0 <random@@GLIBC_2.2.5>: 8.22 │3.92 sub $0x18,%rsp │3.92 mov $0x1,%esi │3.92 xor %eax,%eax │3.92 cmpl $0x0,argp_program_version_hook@@GLIBC_2.2.5+0x │3.92 1 ↓ je 20 │ lock cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+0x8a0 │ ↓ jne 29 │ ↓ jmp 43 │1.10 20: cmpxchg %esi,__abort_msg@@GLIBC_PRIVATE+0x8a0 8.93 │1.10 1 ↓ je 43 Signed-off-by: Jin Yao <yao.jin@linux.intel.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Kan Liang <kan.liang@linux.intel.com> Cc: Peter Zijlstra <peterz@infradead.org> Link: http://lkml.kernel.org/r/1526569118-14217-3-git-send-email-yao.jin@linux.intel.com [ Rename all maxmin to minmax ] Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2018-05-18perf annotate: Record the min/max cyclesJin Yao
Currently perf has a feature to account cycles for LBRs For example, on skylake: perf record -b ... perf report or perf annotate And then browsing the annotate browser gives average cycle counts for program blocks. For some analysis it would be useful if we could know not only the average cycles but also the min and max cycles. This patch records the min and max cycles.

2018-04-12perf annotate: Allow showing offsets in more than just jump targetsArnaldo Carvalho de Melo
Jesper wanted to see offsets at callq sites when doing some performance investigation related to retpolines, so save him some time by providing an 'struct annotation_options' to control where offsets should appear: just on jump targets? That + call instructions? All? This puts in place the logic to show the offsets, now we need to wire this up in the TUI browser (next patch) and on the 'perf annotate --stdio2" interface, where we need a more general mechanism to setup the 'annotation_options' struct from the command line.

2018-03-23perf annotate: Add "_local" to jump/offset validation routinesArnaldo Carvalho de Melo
Because they all really check if we can access data structures/visual constructs where a "jump" instruction targets code in the same function, i.e. things like: __pthread_mutex_lock /usr/lib64/libpthread-2.26.so 1.95 │ mov __pthread_force_elision,%ecx │ ┌──test %ecx,%ecx 0.07 │ ├──je 60 │ │ test $0x300,%esi │ │↓ jne 60 │ │ or $0x100,%esi │ │ mov %esi,0x10(%rdi) │ 42:│ mov %esi,%edx │ │ lea 0x16(%r8),%rsi │ │ mov %r8,%rdi │ │ and $0x80,%edx │ │ add $0x8,%rsp │ │→ jmpq __lll_lock_elision │ │ nop 0.29 │ 60:└─→and $0x80,%esi 0.07 │ mov $0x1,%edi 0.29 │ xor %eax,%eax 2.53 │ lock cmpxchg %edi,(%r8) And not things like that "jmpq __lll_lock_elision", that instead should behave like a "call" instruction and "jump" to the disassembly of "___lll_lock_elision".

2018-03-21perf annotate: Mark jumps to outher functions with the call arrowArnaldo Carvalho de Melo
Things like this in _cpp_lex_token (gcc's cc1 program): cpp_named_operator2name@@Base+0xa72 Point to a place that is after the cpp_named_operator2name boundaries, i.e. in the ELF symbol table for cc1 cpp_named_operator2name is marked as being 32-bytes long, but it in fact is much larger than that, so we seem to need a symbols__find() routine that looks for >= current->start and < next_symbol->start, possibly just for C++ objects? For now lets just make some progress by marking jumps to outside the current function as call like. Actual navigation will come next, with further understanding of how the symbol searching and disassembly should be done.

For the TUI, that is interactive, its interesting to have a configuration that one can go on changing and then when moving from one symbol annotation to another symbol, the options set while browsing the first symbol to be kept. But since we're trying to make this code reusable by a --stdio formatter, we better have a pointer in struct annotation and in the TUI case set it to the global, but use something else for other cases, such as --stdio2.

2018-03-20perf annotate tui: Move have_cycles to struct annotationArnaldo Carvalho de Melo
This is to pave the way to have more functions shared between TUI, stdio and the upcoming stdio2 formatting, that will use the __scnprintf functions used by --tui in a --stdio fashion. This partially addresses the comments added in cset 30e863bb6f70 ("perf annotate: Compute IPC and basic block cycles"): /* * This should probably be in util/annotate.c to share with the tty * annotate, but right now we need the per byte offsets arrays, * which are only here. */ The following patches will address the rest.

This will be useful when making parts of the TUI browser generic enough to be used for a new stdio mode, available even when the TUI is not built in, for explicit user decision or when the necessary library devel files, for the slang library currently, are not available in the build system.

2017-11-13perf annotate: Add annotation_line__(new|delete) functionsJiri Olsa
Changing the way the annotation lines are allocated and adding annotation_line__(new|delete) functions to deal with this. Before the allocation schema was as follows: ----------------------------------------------------------- struct disasm_line | struct annotation_line | private space ----------------------------------------------------------- Where the private space is used in TUI code to store computed annotation data for events. The stdio code computes the data on the fly. The goal is to compute and store annotation line's data directly in the struct annotation_line itself, so this patch changes the line allocation schema as follows: ------------------------------------------------------------ privsize space | struct disasm_line | struct annotation_line ------------------------------------------------------------ Moving struct annotation_line to the end, because in following changes we will move here the non-fixed length event's data.
