10 years agotracing/filters: Provide basic regex support
Frederic Weisbecker [Thu, 24 Sep 2009 19:10:44 +0000]
tracing/filters: Provide basic regex support

This patch provides basic support for regular expressions in filters.

It supports the following types of regexp:

- *match_beginning
- *match_middle*
- match_end*
- !don't match

Example:
cd /debug/tracing/events/bkl/lock_kernel
echo 'file == "*reiserfs*"' > filter
echo 1 > enable

           gedit-4941  [000]   457.735437: lock_kernel: depth: 0, fs/reiserfs/namei.c:334 reiserfs_lookup()
     sync_supers-227   [001]   461.379985: lock_kernel: depth: 0, fs/reiserfs/super.c:69 reiserfs_sync_fs()
     sync_supers-227   [000]   461.383096: lock_kernel: depth: 0, fs/reiserfs/journal.c:1069 flush_commit_list()
      reiserfs/1-1369  [001]   461.479885: lock_kernel: depth: 0, fs/reiserfs/journal.c:3509 flush_async_commits()

Every string is now handled as a regexp in the filter framework, which
helps to factorize the code for handling both simple strings and
regexp comparisons.

(The regexp parsing code has been wildly cherry picked from ftrace.c
written by Steve.)

10 years agotracing/bkl: Add bkl ftrace events
Frederic Weisbecker [Fri, 31 Jul 2009 23:34:24 +0000]
tracing/bkl: Add bkl ftrace events

Add two events lock_kernel and unlock_kernel() to trace the bkl uses.
This opens the door for userspace tools to perform statistics about
the callsites that use it, dependencies with other locks (by pairing
the trace with lock events), use with recursivity and so on...

The {__reacquire,release}_kernel_lock() events are not traced because
these are called from schedule, thus the sched events are sufficient
to trace them.

Example of a trace:

hald-addon-stor-4152  [000]   165.875501: unlock_kernel: depth: 0, fs/block_dev.c:1358 __blkdev_put()
hald-addon-stor-4152  [000]   167.832974: lock_kernel: depth: 0, fs/block_dev.c:1167 __blkdev_get()

How to get the callsites that acquire it recursively:

cd /debug/tracing/events/bkl
echo "lock_depth > 0" > filter

firefox-4951  [001]   206.276967: unlock_kernel: depth: 1, fs/reiserfs/super.c:575 reiserfs_dirty_inode()

You can also filter by file and/or line.

v2: Use of FILTER_PTR_STRING attribute for files and lines fields to
    make them traceable.

10 years agotracing: switch function prints from %pf to %ps
Steven Rostedt [Thu, 17 Sep 2009 04:05:58 +0000]
tracing: switch function prints from %pf to %ps

For direct function pointers (like what mcount provides) PowerPC64
requires the use of %ps, otherwise nothing is printed.

This patch converts all prints of functions retrieved through mcount
to use the %ps format from the %pf.

10 years agovsprintf: add %ps that is the same as %pS but is like %pf
Steven Rostedt [Thu, 17 Sep 2009 00:03:06 +0000]
vsprintf: add %ps that is the same as %pS but is like %pf

On PowerPC64 function pointers do not point directly at the functions,
but instead point to pointers to the functions. The output of %pF expects
to point to a pointer to the function, whereas %pS will show the function
itself.

mcount returns the direct pointer to the function and not the pointer to
the pointer. Thus %pS must be used to show this. The function tracer
requires printing of the functions without offsets and uses the %pf
instead.

 %pF produces run_local_timers+0x4/0x1f
 %pf produces just run_local_timers

For PowerPC64, we need to use the direct pointer, and we only have
%pS which will produce .run_local_timers+0x4/0x1f

This patch creates a %ps that matches the %pf as %pS matches %pF.

Presumably the !wb_has_dirty_io case is not a common one, so it can

bdi_start_writeback() is currently split into two paths, one for

for WB_SYNC_ALL writeback and let bdi_start_writeback() handle
only WB_SYNC_NONE.

Push down the writeback_control allocation and only accept the
parameters that make sense for each function. This cleans up
the API considerably.

writeback: make wb_writeback() take an argument structure

We need to be able to pass in range_cyclic as well, so instead
of growing yet another argument, split the arguments into a
struct wb_writeback_args structure that we can use internally.

Both drivers (rt2860 and rt3090) register themselves as "rt2860" on

In the very rare case of somebody having two cards in his machine, one
using rt3090 and the other one using the rt2860 driver, loading both
modules would be impossible, the second one will not be loaded as the
kernel will tell you that the driver is already registered.

This was also present with rt2870/rt3070 (with both driver registering
as "rt2870"), but the code has been merged to one driver recently.

The follwoing patch fixes this potential problem until merging of

Cowloop is a "copy-on-write" pseudo block driver. It can
be stacked on top of a "real" block driver, and catches
all write operations on their way from the file systems
layer above to the real driver below, effectively shielding
the lower driver from those write accesses. The requests are
then diverted to an ordinary file, located somewhere else
(configurable). Later read requests are checked to see whether
they can be serviced by the "real" block driver below, or

Staging: rtl8192e: fix timeouts on firmware download

We need to actually wait a specific ammount of time, not just hope that
a set number of loops will be long enough.

Based on a conversation with Ralink, and a proposed patch for their
older kernel driver.

Sudhakar Rajashekhara [Thu, 20 Aug 2009 22:13:18 +0000]
Staging: panel: Add support for TI CLCD interface

On TI DA850/OMAP-L138 EVM, HD44780 (24x2) LCD panel is being
used[1], but it is interfaced through the SoC specific LCD
interface and not through parallel port. A parallel port
driver has been developed which interfaces to the panel driver
through the SoC specific LCD interface.

Basically, both the serial and parallel interfaces supported
by the panel driver do not suit the specific interface SoC is
supporting so, a new interface type has been introduced.

Ideally the panel driver should be de-coupled from parallel
and serial port related items but this patch is something
that can be merged in the meantime.
