New Linux ACPI Tool Makes A Debut

Dave Jones, the lead Fedora kernel maintainer and Linux hacker, has released the first bits of code to a new project he has been working. This new tool, acpitool, decodes ACPI tables into something that is almost like a C syntax. It's far from complete but the latest code is available from his personal website with the acpitool release announcement taking place on Dave Jones' blog.

Linux 2.6.23-rc2 "Diseased" Kernel

The Linux 2.6.23-rc2 kernel has been released onto kernel mirrors. This second release candidate introduces some new merges with 250 people contributing patches, but 2.6.23-rc2 is bigger than it should be and it's late as well. Linus Torvalds had stated in his announcement that "this whole '-rc2 is the new -rc1' thing is a disease." This new development kernel includes some driver changes, a MIPS update, and minor alterations all over the kernel. Additional information is available from Kernel Trap.

Linux 2.4.35 Kernel Released

If you're still stuck in the Linux 2.4 kernel series, you'll be happy to know that the Linux 2.4.35 kernel has been released. This kernel comes after six months of work and integrates the changes made in the Linux kernel combined with a number of new PCI IDs, support for high-speed USB HID, and a variety of other improvements for 2.4 kernel users. The 2.4.34.x kernel branch is now closed, but the Linux 2.4.35.x branch is open for patches. Read more at LKML.

Linux Kernel Released

If you're still using the Linux 2.6.16 kernel branch, the Linux release is now available on kernel mirrors. The Linux kernel has a security fix for a remotely triggerable NULL dereference. Among the other fixes include an IEEE-1394 forgotten dereference, array indexing fix in ntfs_init_locked_inode(), and fixing a netpoll deadlock in 8139too. The Linux release announcement can be read on the LKML. Earlier this week the Linux 2.6.23-rc1 kernel was also released.

Linux 2.6.23-rc1 Kernel Released

After a slew of git commits to the kernel tree (including user-space driver API, LGuest virtualization, KVM SMP guests, and Xen), the Linux 2.6.23-rc1 kernel has been released and the merge window is now closed until the Linux 2.6.24 kernel development is underway. Some of the other changes in the Linux 2.6.23-rc1 kernel include the usual architecture and driver updates along side the CFS scheduler and other goodies. The complete Linux 2.6.23-rc1 change-log is available from

Linux Gets Stable Userspace Driver API

A patch for creating a stable user-space driver API has been committed to the Torvalds 2.6 kernel tree and will appear in the Linux 2.6.23 kernel. This stable user-space driver API will make it possible to write much of a driver in user-space and only a small shell of a driver in the kernel. This user-space driver API depends upon a char device and sysfs to interact with a user-space process to handle interrupts and control memory accesses. Currently this driver API will only work out for simple devices and brings no immediate hope for binary graphics drivers.

New Linux Kernel AGP Maintainer

Dave Jones has handed off the reigns to David Airlie as the AGP subsystem maintainer in the Linux Kernel. While working out of Australia, David Airlie recently joined Red Hat and with him being the DRM maintainer the decision was made for him to become the AGP maintainer as well. The git commit of handing off the AGP maintenance can be read from the git web interface.

The Completely Fair Scheduler

Yesterday we also told you about the patches being merged for the Linux 2.6.23 kernel, and now Ingo Molnar's Completely Fair Scheduler has been merged into Linux in time for the 2.6.23 kernel. The Completely Fair Scheduler has been described as modeling an "ideal, precise multi-tasking CPU on real hardware." The new scheduler replaces the O(1) scheduler that has been in the Linux kernel since 2002. Additional information is available at Kernel Trap.

Merging For Linux 2.6.23 Kernel

With the Linux 2.6.22 kernel out the door (as well as the kernel), we are currently in the patch merging phase for the Linux 2.6.23 kernel. Andrew Morton has posted a number of different patches to his -mm kernel tree, but not all of these patches will make it into the mainstream Linux 2.6.23 kernel. Additional information on the merging for the Linux 2.6.23 kernel is available through the gitweb interface and Kernel Trap.

The Status of PATA Support in Linux

After Alan Cox recently posted a status report for libata PATA on the Linux Kernel Mailing List, Kernel Trap has a summary of the Linux IDE status. There is still plenty of work left to be tackled with libata such as adding proper PATA hot-plug support and a PowerPC port. Support for the ATIIXP Chipset is currently rock-solid with Linux and libata while many PATA Chipsets are still deemed experimental.

How-To Write Drivers in Linux

If you've been experimenting with the idea of writing device drivers for Linux, Free Software Magazine has written an extensive article on this topic. The article starts with the differences between kernel-space and user-space components and then ends with using LEDs connected to a parallel port as the device. This how-to guide can be read here.

Linux Kernel & 2.4.35-pre4

If you're still using the Linux 2.4 kernel, being released today is the Linux kernel along with the 2.4.35-pre4 kernel. The day started off with the release of the Linux and the 2.4.35-pre3 kernel, but a fib_semantics patch had broken that build resulting in a same-day re-release. The new 2.4.34 kernel contains a large amount of bug-fixes along with a small security fix. The latest 2.4.35 pre-release kernel features driver updates and other changes. As always, the latest vanilla kernel sources are available from The Linux 2.6.21 kernel should be released in just a matter of days.
