While we have already been benchmarking code for the Linux 2.6.39 kernel a fair amount at Phoronix with the Nouveau page-flipping and z-compression merge plus Nouveau Fermi acceleration, only this afternoon did Linus Torvalds tag the first release candidate for this next major kernel update.
Yesterday Linus voiced his anger towards DRM, once again. But not the kind of DRM that is commonly criticized, Digital Rights Management, but rather the Linux kernel's Direct Rendering Manager. With the Linux 2.6.39 kernel it's been another time when Linus has been less than happy with the pull request for this sub-system that handles the open-source graphics drivers. Changes are needed.
Linus Torvalds is known to have an interesting, colorful e-mail from time to time when becoming frustrated with developers over the quality of patches or when in a very polarized technical debate. In particular, the DRM developers for the Direct Rendering Manager in the kernel (not the restrictive kind, Digital Rights Management) have received a number of critical remarks from Linus. This morning Linus has criticized a second DRM pull request for the Linux 2.6.39 kernel over one of the patches not being ready in advance.
While the Linux 2.6.38 kernel has been out for less than one week, if you use NVIDIA graphics, particularly with a low-end GPU, start counting down the days to the release of the Linux 2.6.39 kernel. Particularly on lower-end NVIDIA GeForce graphics cards, the reverse-engineered open-source Nouveau driver now meets or exceeds the speed of NVIDIA's official proprietary driver in a number of OpenGL test cases.
David Airlie has just emailed Linus Torvalds with his main DRM (Direct Rendering Manager) pull request for the Linux 2.6.39 kernel that 2.6.38 was released earlier this week. As was mentioned a few days ago, the Linux 2.6.39 kernel will feature a number of interesting changes to the open-source graphics drivers, among other areas.
Just as expected, Linus Torvalds released the Linux 2.6.38 kernel over the night. Since the previous Linux 2.6.38-rc8 release there's been some Btrfs file-system updates and other regression fixes throughout, including two fixes for my AMD Fusion Linux problems. Over the Linux 2.6.37 kernel, there's a lot to be found and to enjoy about this new kernel.
While the Linux 2.6.38 kernel isn't even released yet, it's likely to be released in the next day or two. After that and a few days of downtime, the merge window for the Linux 2.6.39 kernel will be opened. What features can one expect for the open-source Linux graphics support? As is usual these days, there's lots of expected changes.
Thomas Renninger of SuSE has announced cpupowerutils, a new free software project derived from cpufrequtils that is designed to offer much more thorough and advanced support for CPU usage/power monitoring and other performance statistics.
The Linux 2.6.38 is effectively ready for release. The condition of the kernel is quite good (hence the large just-published seven-way file-system benchmarks on a SSD and HDD) and Linus noted Monday that when releasing the 2.6.38-rc8 kernel that it could even be considered final, but as he's away for a few days, he went ahead to do one final pre-release.
The stable Linux 2.6.38 kernel is in sight. Linus Torvalds has released the Linux 2.6.38-rc7 kernel, which is much less interesting than his weekend at an Oscar party.
If you're an owner of a netbook or other hardware containing an Intel Poulsbo / GMA 500, the Linux 2.6.39 kernel should be rather exciting. Entering the Linux kernel's staging tree is an initial open-source driver for this notorious Intel graphics processor derived from Imagination Technologies' PowerVR SGX graphics core.
Along with finally delivering Intel Gallium3D driver benchmarks comparing this unofficial, proof-of-concept i915/945 Gallium3D driver to Intel's official classic Mesa driver, there's also our benchmarks of the EXT4 and Btrfs file-systems from the Linux 2.6.38 kernel. These exclusive tests are coming this weekend as part of OpenBenchmarking.org being publicly available for the first day.
The Linux 2.6.38-rc6 kernel has been released. The 2.6.38 kernel is getting into shape and will soon be released with the sixth release candidate carrying a variety of small fixes throughout this open-source kernel.
In his weekly manner, Linus Torvalds has released the Linux 2.6.38-rc5 kernel, This fifth test release isn't particularly exciting, but it brings scattered bug-fixes to the Intel and Radeon graphics drivers, EXT4 file-system fixes, and a RCU file-name lookup bug found under Ubuntu.
Back in September there was the major victory for the open-source and Linux hardware support communities when Broadcom open-sourced an 802.11n Linux driver after years of their WiFi chipsets being notorious under Linux. There's another wireless chipset vendor now getting more serious about open-source driver support too and that's Ralink. They've now contributed patches to the rt2x00 driver project that enables their new RT5390 chipset family to be used by this open-source Linux wireless driver.
The fourth release candidate of the Linux 2.6.38 kernel is now available.
After Linus released an early Linux 2.6.38-rc2 kernel due to the 2011 Linux.Conf.Au, Linus has released the Linux 2.6.38-rc3 kernel while developers are returning from this Australian conference.
In November of 2009 we reported that the Reiser4 file-system may go into the mainline Linux kernel in late 2010. We're now into 2011 with the merge window having closed earlier this month for the Linux 2.6.38 kernel and there's no sign of this open-source file-system designed to succeed the popular ReiserFS. So what gives? Well, we have another update from its lead developer.
Besides the Linux graphics stack being talked about this week at Linux.Conf.Au, there was also a talk by Ted Ts'o about the EXT4 file-system.
The Linux 2.6.38 kernel is shaping up to be very exciting even though it's first release candidate arrived just four days ago. Tonight, however, the Linux 2.6.38-rc1 kernel has already been superseded by the Linux 2.6.38-rc2 release.
After keeping the Linux 2.6.38 kernel merge window open for two weeks, Linus Torvalds has this evening announced the release of the Linux 2.6.38-rc1 kernel. This kernel has a lot to love about it, including Linus' two favorite features of the group scheduling improvements and the RCU-based path name lookup support. Performance improvements!
The organizers behind the Linux Plumbers' Conference have put out a call for track ideas for this Linux conference taking place in Santa Rosa in early September. Jesse Barnes asks that anyone interested read the below message.
Daniel Poelzleithner has announced to the Linux kernel world his new project named ulatencyd. The focus of ulatencyd is to provide a script-able daemon to dynamically adjust Linux scheduling parameters and other aspects of the Linux kernel.
David Airlie has just called upon Linus to pull in his DRM tree for the Linux 2.6.38 kernel. With this being the first 2.6.38 DRM pull request and with the merge window still open, this code brings in a fair amount of exciting work. Here's what those using the popular open-source Linux graphics drivers can find in this next kernel release:
The stable Linux 2.6.37 kernel has now been released. This is the Linux kernel that incorporates Broadcom's new WiFi driver, proper Intel Sandy Bridge support, Btrfs file-system improvements, many open-source graphics DRM/KMS updates, and much more.
For those hoping Linux 2.6.37-rc7 was the last release candidate of the Linux 2.6.37 kernel before going gold, it's not. Linus this evening decided to go ahead and make a Linux 2.6.37-rc8 release.
While in recent years we have seen new Linux kernel releases on Christmas or Christmas Eve, this will not be the case in 2010. Linus has just released the Linux 2.6.37-rc7 kernel making it very unlikely to see any final release (or even another -rc) arrive this week.
Earlier this week there was the release of a new open-source Linux driver by an engineer at Texas Instruments. The TI DMM-TILER is this new driver and its for the dynamic memory manager block on Texas Instruments hardware. "Its purpose is to organize video/image memory in a 2-dimensional fashion to limit memory bandwidth and facilitate 0 effort rotation and mirroring. The TILER driver facilitates allocating, freeing, as well as mapping 2D blocks (areas) in the TILER container(s). It also facilitates rotating and mirroring the allocated blocks or its rectangular subsections."
With it being just over a week since the release of Linux 2.6.37-rc5, Linus Torvalds has this evening put out Linux 2.6.37-rc6. This seventh release candidate to the Linux 2.6.37 kernel is just packing regression fixes as it nears completion.
For those interested in testing out the very latest Linux kernel code, the Linux 2.6.37-rc5 kernel is now available for use.
