[PATCH 05/12] perf, sched migration: Ignore unhandled task states
Stop printing an error message when we don't have the letter for a given task state. All we need to know is if the task is in the TASK_RUNNING state.

[PATCH 08/12] perf, sched migration: Make it vertically scrollable
With scheduler traces covering more than two cpus, rectangles of the CPUs 3 and more are not visibles. This makes the vertical navigation scrollable so that all of the CPUs rectangles are available. We also want to be able to zoom vertically, so that we can fit at best the screen with CPU rectangles, but that'... 1 Aug 2010 21:22

[PATCH 04/12] perf, sched migration: Handle ignored migrate out events
Migrate out events may happen on tasks that are not in the runqueue, for example this is the case for tasks that are sleeping. In this case, we don't want to log the migrate out event in the source runqueue because the task is not eventually in the runqueue and we have already logged its sleep event. This fixes ... 1 Aug 2010 21:22

[PATCH 02/12] tracing: Drop cpparg() macro
Drop the cpparg() macro that wraps CPP parameters. We already have the PARAM() macro for that, no need to have several versions.

[PATCH 06/12] perf, sched migration: Fix key bindings
From: Nikhil Rao <ncrao(a)google.com> EVT_KEY_DOWN and EVT_LEFT_DOWN events are not bound to the RootFrame event handler. As a result, zoom/scroll via keyboard events do not work.

[PATCH 07/12] perf, sched migration: Parameterize cpu height and spacing
From: Nikhil Rao <ncrao(a)google.com> Without vertical zoom, it is not possible to see all CPUs in a trace taken on a larger machine. This patch parameterizes the height and spacing of CPUs so that you can fit more cpus into the screen. Ideally we should dynamically size/space the CPU rectangles with some minimu... 1 Aug 2010 21:22

[GIT PULL] instrumentation updates
Ingo, Please pull the perf/core branch that can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git perf/core A large part is about the new "perf sched migration". It still needs improvements, like fixing some zoom issues, handling sched policies and nice levels, etc...... 1 Aug 2010 21:22

[ANNOUNCE] mtdev v1.0.8 -- Multitouch Protocol Translation Library
mtdev - Multitouch Protocol Translation Library (MIT license) The mtdev library is a kernel input event stream translator, which greatly simplifies multitouch device driver testing as well as handling in applications. The input events are simply routed through mtdev, which transforms them to a uniform stream of M... 1 Aug 2010 20:17
