== 64 bit atomics == * Sent updated set of 64bit atomic patches to gcc list with fixes from previous review * Started hunting for other users of 64bit atomics than membase jemalloc, sdl and boost lock free look like possibilities; but I've not looked at them hard yet

== QEmu == * Released fix for last SD card block access error - Vincent Palatin released a bunch of SD card fixes a few hours later - that included a fix to the same bug; however it does look like he has a bunch of other stuff we should keep sync'd with. * Changing caching mode to writeback on the block layer fixes bug 732223 (hangs on heavy IO) - goes from 130KB/s to 8MB/s on vexpress - Asked mailing list whether that's reasonable to make as default for SD * Looking at path from CPU->MMC/SD card - the DMA on OMAP is pretty inefficiently emulated, but the soc_dma code has an unused special case for dma'ing to hardware, looks promising but need to figure out how to use it and if it works. * Comparing Vincent's SD card patch with earlier meego patches; partial overlap.

== Other == * Pinged libc-ports for comments on my optimised memchr patch * Image testing

Next week; I intend to be in Camborne on the afternoon of Monday, Wednesday and Friday.
