The test attr suite is run only if it's run under perf source directory, or tests are found in installed path. Otherwise tests are omitted (notification is displayed) and finished as successful. Signed-off-by:

The idea is run perf session with kidnapping sys_perf_event_open function. For each sys_perf_event_open call we store the perf_event_attr data to the file to be checked later against what we expect. You can run this by: $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v v2 changes: - preserve errno value in the hook Signed-off-by:

When perf detects no libelf during the build, it'll use internal mini elf parser instead of libelf. But as it only supports minimal functionalities, it also disables support to 'probe' builtin command. Currently it didn't warned to user. Fix it. $ sudo apt-get remove libelf-dev $ make CHK -fstack-protector-all CHK -Wstack-protector CHK -Wvolatile-register-var CHK bionic CHK libelf CHK glibc Makefile:491: No libelf found, disables 'probe' tool, please install elfutils-libelf-devel/libelf-dev CHK libunwind CHK libaudit $ make NO_LIBELF=1 CHK -fstack-protector-all CHK -Wstack-protector CHK -Wvolatile-register-var CHK bionic CHK libaudit Reported-by:Peter Zijlstra <a.p.zijlstra@chello.nl> Signed-off-by:

Create a script browser, so that user can check all the available scripts for current perf data file and run them inside the main perf report or annotation browsers, for all perf samples or for samples belong to one thread/symbol. Please be noted: current script browser is only for report use, and doesn't cover the record phase, IOW it must run against one existing perf data file. The work flow is, users can use function key to list all the available scripts for current perf data file in system and chose one, which will be executed with popen("perf script -s xxx.xx",) and all the output lines are put into one ui browser, pressing 'q' or left arrow key will make it return to previous browser.

Currently checking mmap support in libelf failed due to wrong flags.

There's a portion in the "perf list" output refering to the exact specification of raw hardware events. Since this description is in the perf-list manpage, try to build and install the man pages, warning the user when that is not possible due to missing packages (xmlto and asciidoc). Signed-off-by:

For cross-compiling on Android, some specific changes are needed in the Makefile. Update the Makefile to support cross-compiling for Android. The original ideea for this was send by Bernhard Rosenkraenzer in https://lkml.org/lkml/2012/8/23/316, but this is a rewrite. Changes: () support bionic in addition to glibc () remove rt and pthread libraries that do not exist in Android () use $(CFLAGS) when detecting initial compiler flags. This is needed when setting CFLAGS as an argument of make (e.g. for setting --sysroot). () include perf's local directory when building for Android to be able to find relative paths if using --sysroot (e.g.: ../../include/linux/perf_event.h) Signed-off-by:

on_exit() is only available in new versions of glibc. It is not implemented in Bionic and will lead to linking errors when compiling for Android. Implement a wrapper for on_exit using atexit. The implementation for on_exit is the one sent by Bernhard Rosenkraenzer in https://lkml.org/lkml/2012/8/23/316. The configuration part from the Makefile is different than the one from the original patch. Signed-off-by:

The correct syntax for gcc -x is "gcc -x assembler", not "gcc -xassembler". Even though the latter happens to work, the former is what is documented in the manual page and thus what gcc wrappers such as icecream do expect. This isn't a cosmetic change. The missing space prevents icecream from recognizing compilation tasks it can't handle, leading to silent kernel miscompilations. Besides me, credits go to Michael Matz and Dirk Mueller for investigating the miscompilation issue and tracking it down to this incorrect -x parameter syntax. Signed-off-by:

For building perf without stack backtrace debug, we can set NO_BACKTRACE=1 as a argument of make. It then defines NO_BACKTRACE macro for C code to do the proper handling. However it usually used in a negative semantics - e.g. #ifndef - so we saw double negations which can be misleading. Convert it to a positive form to make it more readable and add _SUPPORT suffix for consistency. Signed-off-by:
