The Linux 3.9 successor will include bcache block layer cache which will allow for caching through the use of SSD cards. Linux 3.9, which was released a couple of weeks back, saw the inclusion of dm-cache, a feature similar to that of bcache, which allows for the use of SSDs for the first time in Linux.
Next up in Linux 3.10 is the support for “full dynamic ticks” that would lessen the timer interrupt’s trigger frequency to just one interrupt per second from up to a thousand (depending on kernel configuration). This will in turn reduce the interrupt processing load of the kernel. Regular users wouldn’t notice that huge a difference when it comes to performance enhancements but, users of real-time systems and those using High Performance Computing (HPC) may find a notable difference.
Taking to the graphics part of the kernel, the Linux 3.10 will come with interfaces that would addressing of the Unified Video Decoder (UVD), which is a part of Radeon HD graphics cards. Userspace drivers for video accelerator are also planned for the next major Mesa 3D release.
