* oom: make oom_score to per-process valueKOSAKI Motohiro2009-09-221-1/+1
| | | | | | | | | | | | | | oom-killer kills a process, not task. Then oom_score should be calculated as per-process too. it makes consistency more and makes speed up select_bad_process().

* tracing, documentation: Add a document on the kmem tracepointsMel Gorman2009-09-221-0/+107
| | | | | | | | | | | | | | | | Knowing tracepoints exist is not quite the same as knowing what they should be used for.

| | | | | | | | | | | | | | | | | | | | | analysis with tracepoints The documentation for ftrace, events and tracepoints is pretty extensive. Similarly, the perf PCL tools help files --help are there and the code simple enough to figure out what much of the switches mean. However, pulling the discrete bits and pieces together and translating that into "how do I solve a problem" requires a fair amount of imagination.

* tracing, page-allocator: add a postprocessing script for ↵Mel Gorman2009-09-221-0/+418
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | page-allocator-related ftrace events This patch adds a simple post-processing script for the page-allocator-related trace events. It can be used to give an indication of who the most allocator-intensive processes are and how often the zone lock was taken during the tracing period. Example output looks like Process Pages Pages Pages Pages PCPU PCPU PCPU Fragment Fragment MigType Fragment Fragment Unknown details allocd allocd freed freed pages drains refills Fallback Causing Changed Severe Moderate under lock direct pagevec drain swapper-0 0 0 2 0 0 0 0 0 0 0 0 0 0 Xorg-3770 10603 5952 3685 6978 5996 194 192 0 0 0 0 0 0 modprobe-21397 51 0 0 86 31 1 0 0 0 0 0 0 0 xchat-5370 228 93 0 0 0 0 3 0 0 0 0 0 0 awesome-4317 32 32 0 0 0 0 32 0 0 0 0 0 0 thinkfan-3863 2 0 1 1 0 0 0 0 0 0 0 0 0 hald-addon-stor-3935 2 0 0 0 0 0 0 0 0 0 0 0 0 akregator-4506 1 1 0 0 0 0 1 0 0 0 0 0 0 xmms-14888 0 0 1 0 0 0 0 0 0 0 0 0 0 khelper-12 1 0 0 0 0 0 0 0 0 0 0 0 0 Optionally, the output can include information on the parent or aggregate based on process name instead of aggregating based on each pid.

While there is a binary format, the expectation is that the binary output can be readily translated into text and post-processed offline. Obviously if the text format changes, the parser will break but the regular expression parser is fairly rudimentary so should be readily adjustable.

* pagemap clear_refs: modify to specify anon or mapped vma clearingMoussa A. Ba2009-09-221-0/+13
| | | | | | | | | | | | | | | | | | | | | | The patch makes the clear_refs more versatile in adding the option to select anonymous pages or file backed pages for clearing. This addition has a measurable impact on user space application performance as it decreases the number of pagewalks in scenarios where one is only interested in a specific type of page (anonymous or file mapped). The patch adds anonymous and file backed filters to the clear_refs interface. echo 1 > /proc/PID/clear_refs resets the bits on all pages echo 2 > /proc/PID/clear_refs resets the bits on anonymous pages only echo 3 > /proc/PID/clear_refs resets the bits on file backed pages only Any other value is ignored Signed-off-by: Moussa A.

| * | tracing, perf: Convert the power tracer into an event tracerArjan van de Ven2009-09-191-17/+0
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the existing power tracer into an event tracer, so that power events (C states and frequency changes) can be tracked via "perf". This also removes the perl script that was used to demo the tracer; its functionality is being replaced entirely with timechart.
