tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire

2014-07-07T16:20:16Z

Commit fb9edbe984 shortened held_lock->check from a 2-bit field to a 1-bit field. Make liblockdep compatible with the new definition by passing check=1 to lock_acquire() calls, rather than the old value check=2 (which inadvertently disabled checks by overflowing to 0). Without this fix, several of the test cases in liblockdep run_tests.sh were failing. Signed-off-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Remove debug print left over from development

2014-07-07T16:14:27Z

Remove a debug print in init_preload() which was left over from development and isn't usefull at all currently. It was also causing false positive test results. Reported-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Fix comparison of a boolean value with a value of 2

2014-07-07T16:02:21Z

Comparison of a boolean value (!__init_state) with a value of 2 (done) as currently happens in the code is unlikely to succeed and causes repeated initialization of the pthread function pointers. Instead, remove boolean comparison so that we would initialize said function pointers only once.

Pull perf updates from Ingo Molnar: "The tooling changes maintained by Jiri Olsa until Arnaldo is on vacation: User visible changes: - Add -F option for specifying output fields (Namhyung Kim) - Propagate exit status of a command line workload for record command (Namhyung Kim) - Use tid for finding thread (Namhyung Kim) - Clarify the output of perf sched map plus small sched command fixes (Dongsheng Yang) - Wire up perf_regs and unwind support for ARM64 (Jean Pihet) - Factor hists statistics counts processing which in turn also fixes several bugs in TUI report command (Namhyung Kim) - Add --percentage option to control absolute/relative percentage output (Namhyung Kim) - Add --list-cmds to 'kmem', 'mem', 'lock' and 'sched', for use by completion scripts (Ramkumar Ramachandra) Development/infrastructure changes and fixes: - Android related fixes for pager and map dso resolving (Michael Lentine) - Add libdw DWARF post unwind support for ARM (Jean Pihet) - Consolidate types.h for ARM and ARM64 (Jean Pihet) - Fix possible null pointer dereference in session.c (Masanari Iida) - Cleanup, remove unused variables in map_switch_event() (Dongsheng Yang) - Remove nr_state_machine_bugs in perf latency (Dongsheng Yang) - Remove usage of trace_sched_wakeup(.success) (Peter Zijlstra) - Cleanups for perf.h header (Jiri Olsa) - Consolidate types.h and export.h within tools (Borislav Petkov) - Move u64_swap union to its single user's header, evsel.h (Borislav Petkov) - Fix for s390 to properly parse tracepoints plus test code (Alexander Yarygin) - Handle EINTR error for readn/writen (Namhyung Kim) - Add a test case for hists filtering (Namhyung Kim) - Share map_groups among threads of the same group (Arnaldo Carvalho de Melo, Jiri Olsa) - Making some code (cpu node map and report parse callchain callback) global to be usable by upcomming changes (Don Zickus) - Fix pmu object compilation error (Jiri Olsa) Kernel side changes: - intrusive uprobes fixes from Oleg Nesterov. Since the interface is admin-only, and the bug only affects user-space ("any probed jmp/call can kill the application"), we queued these fixes via the development tree, as a special exception. - more fuzzer motivated race fixes and related refactoring and robustization. - allow PMU drivers to be built as modules.

tools/liblockdep: Remove all build files when doing make clean

2014-05-08T17:55:13Z

We forgot to remove the shared library with the version number when 'make clean' ran, fix the clean pattern. Signed-off-by: Sasha Levin

tools/liblockdep: Build liblockdep from tools/Makefile

2014-05-08T17:34:45Z

add targets to build liblockdep with make -C tools liblockdep like the way other stuff under tools/ can be built Signed-off-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools: Consolidate types.h

2014-05-01T19:22:39Z

Combine all definitions into a common tools/include/linux/types.h and kill the wild growth elsewhere. Move DECLARE_BITMAP to its proper bitmap.h header.

tools: Unify export.h

2014-05-01T19:18:17Z

So tools/ has been growing three, at a different stage of their development export.h headers and so we should unite into one. Add tools/include/ to the include path of virtio and liblockdep to pick the shared header now.

tools/liblockdep: Add proper versioning to the shared obj

Add proper versioning to the shared obj so that distros would be able to ship this lib without having to worry about versioning. Suggested-by: Josh Boyer Signed-off-by: Sasha Levin

tools/liblockdep: Ignore asmlinkage and visible

2014-04-01T15:46:09Z

Commit 63f9a7fde7 "asmlinkage: Make lockdep_sys_exit asmlinkage" has added asmlinkage annotation to lockdep_sys_exit, which broke build of liblockdep. Since we don't need asmlinkage in liblockep, just ignore it. Reported-by: Eunbong Song Reported-by: Robin Hack Signed-off-by: Sasha Levin
