== 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.
