Status of Embedded Linux
summary
Kernel releases continue at ~63–70 day cadence and mainline now includes f2fs mainlined in 3.8 for flash-optimized filesystems; the CE Workgroup publishes an eMMC tuning study comparing ext4, btrfs and f2fs. Kernel boot can hit ~1 second with product-specific tuning while Android demos use checkpoint/restart to reach ~15 s. New pieces include Android ion memory allocator, in-kernel k‑tap tracing, increasing open GPU driver work, and testing stacks (LAVA/ZeroDay). Static build work yields a 380KB kernel reduction with LTO and demos show booting BeagleBoard in 630 ms.
