Create init functions for exec_cmd.c and pager.c. This allows their configuration to be specified at runtime so they can be split out into a separate library which can be used by other programs.

Generally, calling exit() from a library is bad practice. Eventually these functions might be redesigned so that they don't exit. For now, just document the fact that they do.

When building perf binaries outside the source tree with 'make O=<dir>', the auto-detected features get re-tested for every build, which is unnecessary and inconsistent with the behavior seen when building directly in the source tree. Another issue is that 'make O=<dir> clean' doesn't remove the feature files from the object tree. Fix these problems by looking for the binaries in the $(OUTPUT) directory.

Namhyung Kim authored
Post processing at 'perf record' takes a long time on big machines. What it does is to find the build-id of binaries found in the event stream, so that it can make sure, at 'report' time, that the symtabs (be it ELF, kallsyms, etc) being used to resolve symbols are the ones matching the binaries found at 'record' time. Sometimes we just want to skip this processing of events at the end of the session to get quicker results, making sure the binaries haven't changed from 'record' to 'report' time. Add a new config option to control this behavior. The record.build-id config variable can have one of the following values: - cache: post-process data and save/update the binaries into the build-id cache (in ~/.debug). This is the default. - no-cache: post-process the data but not update the build-id cache. Same effect as using the -N option. - skip: skip post-processing and do not update the cache. Same effect as using the -B option.

Make perf-record command support --vmlinux option if BPF_PROLOGUE is on. 'perf record' needs vmlinux as the source of DWARF info to generate prologue for BPF programs, so path of vmlinux should be specified. Short name 'k' has been taken by 'clockid'. This patch skips the short option name and uses '--vmlinux' for vmlinux path. Documentation is also updated. Test result: In a production (or broken) environment: (by: # rm -rf ~/.debug/ # mv /lib/modules/`uname -r`/build/vmlinux /tmp/ ) # ./perf record -e ./test_bpf_base.c ls Failed to find the path for kernel: No such file or directory event syntax error: './test_bpf_base.c' \___ You need to check probing points in BPF file ... # ./perf record --vmlinux /tmp/vmlinux -e ./test_bpf_base.c ls ...

Wang Nan authored
This patch keeps options of perf builtins same in all conditions. If one option is disabled because of compiling options, users should be notified. Masami suggested another implementation in [1] that, by adding a OPTION_NEXT_DEPENDS option before those options in the 'struct option' array, options parser knows an option is disabled. However, in some cases this array is reordered (options__order()). In addition, in parse-option.c that array is const, so we can't simply merge information in decorator option into the affacted option. This patch chooses a simpler implementation that, introducing a set_option_nobuild() function and two option parsing flags. Builtins with such options should call set_option_nobuild() before option parsing. The complexity of this patch is because we want some of options can be skipped safely. In this case their arguments should also be consumed. Options in 'perf record' and 'perf probe' are fixed in this patch.

We should always return from thread__new(), the constructor, with the object with a reference count of one, so that: struct thread *thread = thread__new(); thread__put(thread); Will call thread__delete(). If any reference is made to that 'thread' variable, it better use thread__get(thread) to hold a reference. We were returning with thread->refcnt set to zero, fix it and some cases where thread__delete() was being called, which were not a problem because just one reference was being used, now that we set it to 1, use thread__put() instead.

We cannot use current->state as was done previously, because the instruction after the store to that variable it can be changed. We must instead pass the initial state along and use that.

Pull arm64 fixes from Catalin Marinas: - Update the linker script to use L1_CACHE_BYTES instead of hard-coded 64. We recently changed L1_CACHE_BYTES to 128 - Improve race condition reporting on set_pte_at() and change the BUG to WARN_ONCE. With hardware update of the accessed/dirty state, we need to ensure that set_pte_at() does not inadvertently override hardware updated state. The patch also makes the checks ignore !pte_valid() new entries * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64: Improve error reporting on set_pte_at() checks arm64: update linker script to increased L1_CACHE_BYTES value
