It seems that I haven't yet used to the weekly activity reports, but from now on I'll try to set it right.

=== Highlights ===

* Got a new toy (almost a Christmas present): a pandaboard. :-) Played with it a little bit: tried Linaro (w/ a serial console, no GUI), various kernels, including linux-next. * In addition to the pandaboard, set up a Linaro QEMU environment for quick tests; especially useful when not having access to a real HW; * Finally felt confident enough to send out my thoughts on the memory killer; * From the discussion it seems that: - Now mem_cg is a lot better on memory usage, but still not enough for embedded use; - cgroups has a big impact on the kernel size image; - cgroups impacts performance in a bad way (using not so synthetic hackbench): http://lkml.org/lkml/2011/12/21/487 (purely synthetic tests, like cyclictest, do not show any downgrade); - there are still some demand for the dedicated memory notifiers; So, it seems that mem_notify reincarnation is inevietable.

=== Plans ===

* I haven't yet able to boot Linaro/Android on the pandabord, need a HDMI-DVI cable, I'll get it soon; I've tried to boot Android on the QEMU/VExpress, but it took ages (4+ hours) only to get it to the welcome screen (I was trying on my travel x120e notebook, 1.6 GHz. But I will try on a more powerful machine soon, just out of curious). * I'll take some side project, also Android related. This is to have some "rest" from the lowmemory notifiers/killer; * Address some community comments on the current lowmemorykiller driver; * Start implementing "low memory notify" driver.
