Linux 2.6.31 kernel came out

After the 9 candidates for release on Sept. 9 at 16 pm Pacific time (3 am on Sept. 10 Moscow time), Linus has released 2.6.31 kernel Linux.

The main and most important changes in this version:

* Added support for interface USB 3.0, and although the market has no devices that use this interface, the Linux kernel already implements xHCI (v 0.95) [eXtencible Host Controller Interface].

* Added a new interface CUSE - Character device implementation in user space, extending the interface FUSE (filesystem in userspace - file system in user space). Using CUSE possible proxying, such as OSS devices to work with ALSA. Currently work is realized with the use of OSS pulsaudio as a terminal device.

* Improved behavior of the system in terms of memory. Because the algorithm processed displacement pages that contain executable code, improved response of the system in terms of memory - pages that contain the executable code of the active application is now less likely to be pushed to the pagefile. Number of misses the cache memory is reduced from 50% to 3.10%.

* Support for native video modes for cards AMD / ATI in the nucleus (KMS - kernel mode setting). Supported chips: R1XX, R2XX, R3XX, R4XX, R5XX (radeon up to X1950). In: R6XX, R7XX and newer (radeon from HD2XXX to HD4XXX).

* Added performance counters

* And much more
