Another Shot At The KMS Page-Flipping Ioctl

Being worked on for the past several months by Kristian Høgsberg and other developers has been the KMS page-flipping ioctl, which makes it possible for kernel mode-setting drivers to benefit from tear-free updating of the screen with low-latency page-flipping. This kernel DRM ioctl is also a requirement for the Wayland Display Server. The page-flipping ioctl should have made it into the Linux 2.6.32 kernel, but it didn't end up happening due to some last minute work.

Linux 2.6.32-rc6 Kernel Now Released

The Linux 2.6.32-rc5 kernel was released over two weeks ago, but it was not until today that 2.6.32-rc6 was tagged. This is not because of Linus's affection towards Windows 7, but rather the Linux Kernel Summit that was taking place in Tokyo and a nasty data-loss-causing EXT4 regression had to be tracked down and addressed. Linux 2.6.32-rc6 is available though right now and it carries a good number of changes considering the time-span between releases, including some regression fixes that were introduced during the 2.6.31 cycle and various driver updates.

Ryan Gordon Brings Universal Binaries To Linux

One of the interesting features of Mac OS X is its "universal binaries" feature that allows a single binary file to run natively on both PowerPC and Intel x86 platforms. While this comes at a cost of a larger binary file, it's convenient on the end-user and on software vendors for distributing their applications. While Linux has lacked such support for fat binaries, Ryan Gordon has decided this should be changed. This professional game porter has created the FatELF project, which basically brings the universal binaries feature to Linux. The FatELF file format allows multiple binaries for different architectures to be embedded into a single file. Ryan may take this even further by introducing the ability for Solaris and FreeBSD binaries to be embedded into a FatELF as well.

Linux 2.6.32-rc5 Kernel Released

The Linux 2.6.32-rc4 kernel was released merely four days ago, but as planned, the Linux 2.6.32-rc5 kernel is now available. This release candidate that just accumulates four days worth of patches is coming due to the annual Linux kernel summit that is coming up and will take Linus Torvalds and other key kernel developers away for a few days. Most of the changes though in Linux 2.6.32-rc5 come down to driver changes, with the addition of two new network drivers (stmmac and vmxnet3) and then various other updates.

Linux 2.6.32-rc4 Brings A Huge, Bloated Driver

As another Sunday release, Linus has made the Linux 2.6.32-rc4 kernel release. 60% of the patch for this release is the result of the addition of a single new SCSI FC driver. Linus refers to this SCSI driver as being "huge and bloated", but he has vowed not to merge "drivers-from-hell" anymore. The remainder of Linux 2.6.32-rc4 is made up of driver updates and Blackfin architecture updates. Worth noting from on the DRM side is that the ATI kernel mode-setting improvements talked about a few days ago were merged into this release candidate for Linux 2.6.32.

Linux 2.6.32-rc3 Kernel Released, No -rc2

Linus Torvalds has a week after the release of Linux 2.6.32-rc1, a new release candidate for this Linux kernel is available. However, it's not Linux 2.6.32-rc2 but actually Linux 2.6.32-rc3, due to a bug in the -rc1 "Makefile" calling it actually -rc2 at the time. Anyhow, this update contains a variety of fixes through the usual drivers, file-systems, architectures, and more. The Linux 2.6.32-rc3 release announcement can be read at LKML.org.

Intel, ATI Kernel Mode-Setting Continues To Mature

There's been a whole flurry of activity going on within the kernel mode-setting world if you have looked at any of the Phoronix news entries from the past weeks. With the Linux 2.6.32 merge window opening up, activity on KMS for ATI and Intel hardware especially has increased. Just a few hours ago we talked about patches being pushed out that provide ATI power management for KMS (well, the initial bits of support) and then earlier this week confirmation of many KMS improvements in Linux 2.6.32 (including R600/700 mode-setting, 3D), but this afternoon there's new patches to talk about. One set of patches is for Intel, the other is for ATI/AMD.

Linux 2.6.31 Kernel Released, With ATI KMS Glory

It's arriving a few days later than anticipated, but the Linux 2.6.31 kernel has now been released. The Linux 2.6.31 kernel brings ATI Radeon kernel mode-setting support up through the R500 series (the R600/700 KMS and 3D support is coming with Linux 2.6.32), many other graphics / DRM improvements (including Intel DisplayPort and Clarkdale / Arrandale support), a performance counters infrastructure, USB 3.0 support, and many more changes.

New, Updated Drivers Coming To Linux 2.6.32

With the Linux 2.6.32 kernel merge window opening up this month, open-source developers around the world have been busy working on their code that they wish to push into this next major kernel update. There is already 3D and KMS support coming to the R600/700 hardware from ATI with this next kernel release along with the KMS page-flipping ioctl and other graphics-related changes, but now Novell's Greg Kroah-Hartman has written a lengthy message detailing the status of the different drivers in the staging tree for Linux 2.6.32.

Linux 2.6.31 Kernel Pushed Back, 9th RC Arrives

A week ago Linus Torvalds was looking at releasing the Linux 2.6.31 kernel in time for Labor Day (tomorrow in the US), but he has decided against that and has now issued a ninth release candidate. Due to a last minute surge in commits against the Linux 2.6.31 kernel, Linus decided to hold off the release of this new kernel for a few days and instead issue Linux 2.6.31-rc9. This new release candidate brings a few fixes and other corrections (including some Intel KMS adjustments).

Discussion: Partial Open-Source GPU Drivers

Last week VIA re-released their Chrome 9 DRM in hopes of pushing it into the mainline Linux kernel. However, the only user of this DRM code at present is their Linux binary graphics driver and VIA Technologies has no intentions of providing an open-source Chrome 9 3D driver. However, within a month or so, VIA claims to be releasing a new 2D driver that can use this DRM to some extent. This whole situation with VIA has reignited the discussion over what to do when a company is interested in pushing an open-source DRM driver into the mainline Linux tree, but it's really only used by closed-source user-space drivers.
