2013-10-10i2c: omap: Clear ARDY bit twiceTaras Kondratiuk
Initially commit cb527ede1bf6ff2008a025606f25344b8ed7b4ac "i2c-omap: Double clear of ARDY status in IRQ handler" added a workaround for undocumented errata ProDB0017052. But then commit 1d7afc95946487945cc7f5019b41255b72224b70 "i2c: omap: ack IRQ in parts" refactored code and missed one of ARDY clearings. So current code violates errata. It causes often i2c bus timeouts on my Pandaboard. This patch adds a second clearing in place.

2013-10-10i2c: Not all adapters have a parentJean Delvare
The code in acpi_i2c_register_devices() assumes that all i2c adapters have a parent. This is not necessarily the case, for example the i2c-stub driver instantiate a virtual i2c adapter without a parent. Check for this to avoid a NULL pointer deference.

2013-10-09perf trace: Show path associated with fd in live sessionsArnaldo Carvalho de Melo
For live sessions we can just access /proc to map an fd to its path, on a best effort way, i.e. sometimes the fd will have gone away when we try to do the mapping, as it is done in a lazy way, only when a reference to such fd is made then the path will be looked up in /proc. This is disabled when processing perf.data files, where we will have to have a way to get getname events, be it via an on-the-fly 'perf probe' event or after a vfs_getname tracepoint is added to the kernel. A first step will be to synthesize such event for the use cases where the threads in the monitored workload exist already.

2013-10-09perf tools: Fix srcline sort key behaviorNamhyung Kim
Currently the srcline sort key compares ip rather than srcline info. I guess this was due to a performance reason to run external addr2line utility.

2013-10-09hwmon: (applesmc) Always read until end of dataHenrik Rydberg
The crash reported and investigated in commit 5f4513 turned out to be caused by a change to the read interface on newer (2012) SMCs. Tests by Chris show that simply reading the data valid line is enough for the problem to go away. Additional tests show that the newer SMCs no longer wait for the number of requested bytes, but start sending data right away. Apparently the number of bytes to read is no longer specified as before, but instead found out by reading until end of data. Failure to read until end of data confuses the state machine, which eventually causes the crash. As a remedy, assuming bit0 is the read valid line, make sure there is nothing more to read before leaving the read function. Tested to resolve the original problem, and runtested on MBA3,1, MBP4,1, MBP8,2, MBP10,1, MBP10,2. The patch seems to have no effect on machines before 2012.

2013-10-09perf symbols: Add new option --ignore-vmlinux for perf topWilly Tarreau
Running "perf top" on a machine with possibly invalid or non-matching vmlinux at the various places results in no symbol resolving despite /proc/kallsyms being present and valid. Add a new option --ignore-vmlinux to explicitly indicate that we do not want to use these kernels and just use what we have (kallsyms).

2013-10-09perf tools: Adding throttle event data struct supportJiri Olsa
Moving 'struct throttle_event' out of python code and making it global as any other event. There's no usage of throttling events in any perf commands so far (besides python support), but we'll need this event data backup for upcoming test.

Adding new common function to create evlist with default event. It spares some code lines in automated tests.

2013-10-09perf tools: Add possibility to specify mmap sizeJiri Olsa
Adding possibility to specify mmap size via -m/--mmap-pages by appending unit size character (B/K/M/G) to the number, like: $ perf record -m 8K ls $ perf record -m 2M ls The size is rounded up appropriately to follow perf mmap restrictions. If no unit is specified the number provides pages as of now, like: $ perf record -m 8 ls Signed-off-by: Jiri Olsa <jolsa@redhat.com> Cc: Andi Kleen <ak@linux.intel.com> Cc: Corey Ashford <cjashfor@linux.vnet.ibm.com> Cc: David Ahern <dsahern@gmail.com> Cc: Frederic Weisbecker <fweisbec@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1378031796-17892-3-git-send-email-jolsa@redhat.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2013-10-09perf tools: Check mmap pages value earlyJiri Olsa
Move the check of the mmap_pages value to the options parsing time, so we could rely on this value on other parts of code. Related changes come in the next patches. Also changes perf_evlist::mmap_len to proper size_t type.
