Among the many additions to drivers and support for infrastructure is one of AMD's Fusion APUs . The Accelerated Processing Units integrate multiple processor cores on one die and a DirectX 11-capable graphics chip. The Wi-Fi drivers for chips from Atheros, Broadcom, Intel, Ralink and Realtek were optimized.
The most important innovation is the "wonder patch" advertised function Automatic Grouping Process: It shares the CPU processing power on so that slow is not particularly power-hungry processes them. These changes in the process scheduler to significantly reduce the latency and response such as desktop environments much more quickly.
Another important change and Torvalds' personal favorite is the improved scalability of the Virtual File System (VFS). The use of RCU (Read Copy Update) are file system operations that use a lot of file paths, massively accelerated. Of which will benefit nearly every program on a multi-core processor system even if it uses only a single thread.
The file system Btrfs untertützt now an alternative to the zlib compression algorithm, LZO . Moreover, it can now write protected create snapshots.
Transparent Huge Pages make it possible, 4 KByte memory pages to use in transparent applications over. This increases the performance of memory management, while the memory requirements decrease. A list of all changes in kernel 2.6.38 is found in the 6.3 MByte Changelog . For more information, visit kernelnewbies.org .
The new Linux kernel 2.6.38 will include the distributions in Fedora 15 and Ubuntu 11:04 come to use. Both are to appear in April.
