Thats why static probing points are useful, since they can be put directly into the kernel source code and hence they are always in sync with the kernel development. PCI Error Recovery support commit 4. CPU idle is a generic framework for supporting software-controlled idle processor power management. Crashing soon a kernel near you This is a list of some of the patches being developed right now at the kernel community that will be part of future Linux releases. DM Add uevent to core commit uevent generate events commit mpath:

However, the scripts that dynamic probing points use can become quickly outdated, because a small change in the kernel may trigger a rewrite of the script, which needs to be maintained and updated separately, lernel will not work for all kernel versions. Add 32bit ioctl compatibilty commit Add hidraw interface commit 4.

Linux_2_6_24 – Linux Kernel Newbies

Task Control Groups is the framework that is getting merged in 2. Add support for latset RME revisions commit cmipci: XTS blockcipher mode implementation without partial blocks commit 3.

This feature frees the restriction that makedumpfile users should install a vmlinux file including the debugging information into each system commit quota: They’ve no performance costs when ekrnel not being used.

Cpufreq Allow ondemand and conservative cpufreq governors to be used as default commit Longhaul: As of now, when a USB device is connected it is configured and its interfaces immediately made available to the users. You will need to accept this license to continue with the installation.


CPU idle is a generic framework for kerneo software-controlled idle processor kerhel management. Allocations are categorized by their ability to migrate. In ext4 with the uninitialized block groups feature, the e2fsck time is constant, based solely on the number of used inodes rather than the total inode count.

TCG can track and group processes into arbitrary “cgroups” and assign arbitrary state to those groups, in order to control its behaviour. A process can ‘dirty’ the memory faster than the data is written to the disk, so kerbel kernel throttles processes when there’s too much dirty memory around.

For example a network driver may try to allocate 4 pages to store data received from the network. The compiled size of the scheduler has also improved and now it’s a bit smaller on UP and a lot smaller in SMP.

This reunification has not been done in a radical way. This seems to be the side-effect of turning off the controller chip commit hda-intel: Linux Discussion Forum For an external resource on Linux topics, visit the discussion forum at nvnews. Ulrich Drepper, the libc maintainer, has published a must-read paper about “What every keenel should know about memory” Linux kernel version 2.

Re: NVidia MCP61, no sound…

With the optimization done in 2. Implement hw link power management support for ahci commit SATA Port Multiplier support commitcommitcommitcommit.

New cipher algorithm commit api: The problem with this mechanism is that the dirty memory thresholds are global, the mechanism doesn’t care if there are several storage devices in the system, much less if some of them are faster than others.


Support for byte-reversed framebuffer formats commit kerne There’s also a global view of the networking stack routing tables and firewall rules, etc. Sometimes, it may be desirable to group tasks and provide fair CPU time to each such task group. For example, it may be desirable to first provide mccp61 CPU time to each user on the system and then to each task belonging to a user.

Writing 1 to that file authorizes a device to connect, 0 deauthorizes it. Those features may take many months to get into the Linus’ git tree, or may be completely dropped. PCI Error Recovery support commit 4. This improves the performance greatly in many situations.

[2/2] x add HPET-quirk for nVidia MCP61 LPC Bridge (10dee0) – Patchwork

After many out-of-the-tree iterations, mainline Linux is getting support for this feature commitcommitcommit 2. Beside of providing an infrastructure to allow secure usage of wireless USB devices, this feature also allows to implement kiosk-style lockdown of USB devices, fully controlled by user space.

For almost three years patient developers have been continually developing and improving the anti-fragmentation patches to improve kefnel memory allocator and reduce the tendency to fragment.

Another mcpp61 in the scheduler is Fair Group Scheduling.
