* tracing/events: move the ftrace event tracing code to coreSteven Rostedt2009-04-14
| | | | | | | | | | | | This patch moves the ftrace creation into include/trace/ftrace.h and simplifies the work of developers in adding new tracepoints. Just the act of creating the trace points in include/trace and including define_trace.h will create the events in the debugfs/tracing/events directory. This patch removes the need of include/trace/trace_events.h Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* tracing/events: move declarations from trace directory to core includeSteven Rostedt2009-04-14
| | | | | | | | | | In preparation to allowing trace events to happen in modules, we need to move some of the local declarations in the kernel/trace directory into include/linux. This patch simply moves the declarations and performs no context changes. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* tracing: make trace_seq operations available for core kernelSteven Rostedt2009-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | In the process to make TRACE_EVENT macro work for modules, the trace_seq operations must be available for core kernel code. These operations are quite useful and can be used for other implementations. The main idea is that we create a trace_seq handle that acts very much like the seq_file handle. struct trace_seq *s = kmalloc(sizeof(*s, GFP_KERNEL); trace_seq_init(s); trace_seq_printf(s, "some data %d\n", variable); printk("%s", s->buffer); The main use is to allow a top level function call several other functions that may store printf like data into the buffer. Then at the end, the top level function can process all the data with any method it would like to. It could be passed to userspace, output via printk or even use seq_file: trace_seq_to_user(s, ubuf, cnt); seq_puts(m, s->buffer); Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
* tracing: create automated trace definesSteven Rostedt2009-04-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch lowers the number of places a developer must modify to add new tracepoints. The current method to add a new tracepoint into an existing system is to write the trace point macro in the trace header with one of the macros TRACE_EVENT, TRACE_FORMAT or DECLARE_TRACE, then they must add the same named item into the C file with the macro DEFINE_TRACE(name) and then add the trace point. This change cuts out the needing to add the DEFINE_TRACE(name). Every file that uses the tracepoint must still include the trace/<type>.h file, but the one C file must also add a define before the including of that file. #define CREATE_TRACE_POINTS #include <trace/mytrace.h> This will cause the trace/mytrace.h file to also produce the C code necessary to implement the trace point. Note, if more than one trace/<type>.h is used to create the C code it is best to list them all together. #define CREATE_TRACE_POINTS #include <trace/foo.h> #include <trace/bar.h> #include <trace/fido.h> Thanks to Mathieu Desnoyers and Christoph Hellwig for coming up with the cleaner solution of the define above the includes over my first design to have the C code include a "special" header. This patch converts sched, irq and lockdep and skb to use this new method.

* tracing: consolidate trace and trace_event headersSteven Rostedt2009-04-14
| | | | | | | | | | | | | | | | | | | | | | | | Impact: clean up Neil Horman (et. al.) criticized the way the trace events were broken up into two files. The reason for that was that ftrace needed to separate out the declarations from where the #include <linux/tracepoint.h> was used. It then dawned on me that the tracepoint.h header only needs to define the TRACE_EVENT macro if it is not already defined. The solution is simply to test if TRACE_EVENT is defined, and if it is not then the linux/tracepoint.h header can define it. This change consolidates all the <traces>.h and <traces>_event_types.h into the <traces>.h file.

* tracing/filters: allow on-the-fly filter switchingTom Zanussi2009-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows event filters to be safely removed or switched on-the-fly while avoiding the use of rcu or the suspension of tracing of previous versions. It does it by adding a new filter_pred_none() predicate function which does nothing and by never deallocating either the predicates or any of the filter_pred members used in matching; the predicate lists are allocated and initialized during ftrace_event_calls initialization. Whenever a filter is removed or replaced, the filter_pred_* functions currently in use by the affected ftrace_event_call are immediately switched over to to the filter_pred_none() function, while the rest of the filter_pred members are left intact, allowing any currently executing filter_pred_* functions to finish up, using the values they're currently using. In the case of filter replacement, the new predicate values are copied into the old predicates after the above step, and the filter_pred_none() functions are replaced by the filter_pred_* functions for the new filter. In this case, it is possible though very unlikely that a previous filter_pred_* is still running even after the filter_pred_none() switch and the switch to the new filter_pred_*. In that case, however, because nothing has been deallocated in the filter_pred, the worst that can happen is that the old filter_pred_* function sees the new values and as a result produces either a false positive or a false negative, depending on the values it finds. So one downside to this method is that rarely, it can produce a bad match during the filter switch, but it should be possible to live with that, IMHO. The other downside is that at least in this patch the predicate lists are always pre-allocated, taking up memory from the start. They could probably be allocated on first-use, and de-allocated when tracing is completely stopped - if this patch makes sense, I could create another one to do that later on. Oh, and it also places a restriction on the size of __arrays in events, currently set to 128, since they can't be larger than the now embedded str_val arrays in the filter_pred struct.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When gen_initramfs_list is used to generate make dependencies, it includes symbolic links, for which make tracks the link target. Any change to that target will cause an initramfs rebuild, even if the symlink points to something outside of the initramfs directory. If the target happens to be /tmp, the rebuild occurs for each kernel build, since gen_initramfs_list uses mktemp... Proposed way to fix it is to omit symbolic links from generated dependencies, but this has a small drawback: changing perm/owner on a symlink will go unnoticed.

The offending string is the following, and it's located in drivers/staging/panel/Kconfig:72: "'\e[L' which are specific to the LCD, and a few ANSI codes. The" looks to me like gettext expects strings in printf format, so in this case it thinks "\e" is a control sequence but doesn't recognise it as a valid one. A valid solution would be to tell kxgettext to automatically escape this kind of strings in the */config.pot he produces, so that msguniq would not complain. ===== This patch implements the suggested escaping.

The other one is accessible through GPIO pin 1. Sadly, this pin is being multiplexed with UART0 input, so enabling it as interrupt source (as implied by the gpio-keys driver) is not possible unless UART0 has been turned off. The later one though is a rather bad idea as the Routerboard is an embedded device with only a single serial port, so it's almost always used as serial console device. This patch adds a driver based on INPUT_POLLDEV, which disables the UART and reconfigures GPIO pin 1 temporarily while reading the button state. This procedure works fine and has been tested as part of another, unpublished driver for this device. Signed-off-by: Phil Sutter <n0-1@freewrt.org> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

This causes later information to run into it, and for that to be categorised incorrectly at KERN_DBG. Fix this up.

They inherit the values from the module parameters when the device is registered. One additional benefit is that now runtime changes to channel_mask can actually affect the hardware channel setup like they should.

[dtor@mail.ru: This changes autorepeat behavior a bit since we now stop autorepeat even if key that is being released is not the one that is being auto-repeated, but I believe the new behavior is better.] Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

In addition, if the resume from hibernation is userland-driven, it's better to wait for all device probes in the kernel to complete before attempting to open the resume device.
