| The purpose of this page is tracking and explaining the features added in every release, just like the [http://wiki.dragonflybsd.org/index.php/DragonFly_Status Dragonfly people did]. | #pragma keywords Linux, Kernel, Operative System, Linus Torvalds, Open Source, drivers, filesystems, network, memory management, scheduler, preemtion, locking #pragma description Summary of the changes and new features merged in the Linux Kernel during the 2.6.x and 3.x development Changes done in each Linux kernel release. Other places to get news about the Linux kernel are [http://lwn.net/Kernel/ LWN kernel status], [http://www.h-online.com/open/features/ H-Online], or the Linux Kernel mailing list (there is a web interface in [http://www.lkml.org www.lkml.org]). List of changes of older releases can be found at LinuxVersions. If you're going to add something here look first at LinuxChangesRules! |

| It'd be nice if kernel hackers would spend some minutes adding their stuff here. The one place where you can find a comparable changelog are the fabulous LWN kernel articles: http://lwn.net/Kernel/, or the [http://lwn.net/Articles/driver-porting/ driver porting guide] - but there's no reason why the kernel community shouldn't embrace and extend those efforts ;) | You can discuss the latest Linux kernel changes on the [http://forum.kernelnewbies.org/list.php?4 New Linux Kernel Features Forum]. |

By preserving the memory contents in a crash scenario, kexec allows to implement kdump. Kdump is able to get a memory dump of the previous kernel, and be used as a debugging tool. * [http://lwn.net/Articles/135472/ Execute-in-place support]: Traditionally, programs are loaded from disk to memory to be executed. However, the current wave of embedded devices store programs in a ROM/flash chip. XIP allows the kernel executing programs directly from that ROM, without being copied to RAM (saving RAM space), and bypassing the page cache/io scheduler layers (since they're not needed). * [http://lwn.net/Articles/145973/ build-time configurable clock interrupt frequency]: * [http://lwn.net/Articles/143474/ Improved CFQ IO scheduler] * Voluntary preemption patches * Removal of the devfs configuration option 2.6.12: * [http://lwn.net/Articles/140164/ API changes] * New driver for the "trusted computing" (TPM) crap^Wchip * [http://www.superh.com/products/shyway.htm SuperHyway bus support] * Multilevel security implementation for SELinux * [http://lwn.net/Articles/124703/ device mapper multipath support] * [http://lwn.net/Articles/121845/ Address space randomization] * Restore the Philips webcam driver * I/O barrier support for serial ATA drives * [http://lwn.net/Articles/134460/ "resource limits"] * [http://lwn.net/Articles/127936/ cpusets] * Remove IPV6 "experimental" status 2.6.11: 2.6.10: 2.6.9: 2.6.8: 2.6.7: 2.6.6: 2.6.5: 2.6.4: 2.6.3: 2.6.2: 2.6.1: 2.6.0: 2.6.0-test9: * [http://lwn.net/Articles/44243/ libata driver architecture] (Jeff Garzik) 2.6.0-test6: * [http://marc.theaimsgroup.com/?l=linux-kernel&m=104344596912094&w=2 32-bit dev_t] (Andries Brouwer, Al Viro) 2.6.0-test3: * [http://www.nsa.gov/selinux/index.html SELinux] (Stephen Smalley, SELinux team) 2.6.0-test1: * [http://www.linuxvirtualserver.org/ Linux Virtual Server layer] (Wensong Zhang) 2.5.75: * [http://marc.theaimsgroup.com/?l=linux-mm&m=104529418208788&w=2 Anticipatory Scheduler] (Nick Piggin, Andrew Morton) 2.5.71: * [http://marc.theaimsgroup.com/?l=linux-kernel&m=104981044405395&w=2 Switch the IDE I/O layers to taskfile](Bartlomiej Zolnierkiewicz, Alan Cox) 2.5.70: * [http://www.linux-usb.org/gadget USB gadget support] (David Brownell, Stuart Lynne, Greg Kroah-Hartman) 2.5.69: * [http://lwn.net/Articles/29555/ New interrupt handling API] (Linus Torvalds, Andrew Morton, etc.) 2.5.65: * [http://www.kerneltrap.org/node.php?id=603 Desktop Interactivity Improvements] (Linus Torvalds, Ingo Molnar) 2.5.63: * [http://high-res-timers.sourceforge.net/ POSIX timers] (George Anzinger) 2.5.60: * New modversions implementation (Kai Germaschewski) * 64-bit jiffies (Tim Schmielau) 2.5.59: * [http://home.arcor.de/efocht/sched/ NUMA aware scheduler extensions] (Erich Focht, Michael Hohnbaum, Martin Bligh) 2.5.57: * [http://www.zipworld.com.au/~akpm/linux/schedlat.html Remove long-held locks for low scheduling latency] (Andrew Morton, etc.) 2.5.54: * [http://secure.netroedge.com/~lm78/ Add drivers for hardware health monitoring] (lm_sensors team) |
