David Herrmann continues his GSoC summer project of implementing DRM Render Nodes support and as part of that VMA Access Management for the Linux kernel.
With the Linux 3.11 kernel due to be released in the coming weeks, here's an overview of the most exciting changes for this next major Linux kernel update.
Linus Torvalds released the Linux 3.11-rc6 kernel on Sunday evening. This sixth release candidate is fairly quiet for the Linux 3.11 kernel, but Linus is already planning to time the 3.11-rc7 release to celebrate the 22nd birthday of Linux.
The zRAM Linux kernel module that aims to increase Linux's performance by avoiding paging to disk and optimizing to use a compressed block device in RAM, may finally leave the Linux kernel staging area and be promoted to main. This code that mostly benefits users with limited amounts of system RAM has become quite mature and is becoming widely adopted, which in part is why it's trying to be promoted out of the staging area.
Twenty years ago today Microsoft released Windows 3.11 while today Linus Torvalds released the Linux 3.11-rc5 kernel. He wished he could have released Linux 3.11 kernel final today, but that didn't happen.
The Common Display Framework (CDF) proposal for the Linux kernel that started last year is still being worked on. The CDF code is now up to its third revision, but this isn't likely to be the final revision before pushing it for mainline inclusion.
Separate from the important Radeon DPM support in Linux 3.11 that can sharply lower system power usage when using this forthcoming kernel update, there's been other power-related changes in recent Linux kernel releases.
It's time for another Sunday release of the Linux kernel. While it's out on schedule, the Linux 3.11-rc4 release carries about the same amount of changes as 3.11-rc3, which isn't making Linus Torvalds happy.
A power capping framework has been proposed for the mainline Linux kernel to provide some standard interfaces for the increasing amount of drivers/hardware that support power monitoring and limiting.
Cross-device synchronization support for DMA-BUF is still being worked on for a future Linux kernel release.
The third release candidate is out for the Linux 3.11 kernel and it incorporates many more patches -- too many more than Linus Torvalds would prefer at this time.
On Friday I reported that the Linux 3.11 kernel may lower power consumption for Intel systems. Since then, additional power consumption tests have revealed there are some changes within the Linux 3.11 but overall recent kernel releases are in better shape than the past.
It's still being investigated, but early indications are that the Linux 3.11 kernel is consuming less power at least for Intel CPUs.
Patches to support compressing SquashFS file-systems with the LZ4 compression algorithm have been proposed for the mainline Linux kernel, but it's not clear at the moment whether the work will be accepted.
Samsung Electronics has dramatically ramped up their Linux hiring and development efforts in the past three years and they are still on track for hiring another 20,000 Linux and open-source developers.
Rob Clark has posted the second version of his MSM DRM driver, an open-source reverse-engineered kernel Direct Rendering Manager driver for Qualcomm's "Snapdragon" SoCs.
Linus Torvalds on Sunday announced the second release candidate for the Linux 3.11 kernel.
Linus Torvalds is usually complaining about too many pull requests during the Linux kernel development cycle when past its merge window, but this time around he's complaining about too few patches this week. He's also proclaimed himself the Goldilocks of kernel development.
Linus Torvalds announced the Linux 3.11-rc1 release on Sunday afternoon.
Nearing the end of the Linux 3.11 kernel with most (if not all) of the interesting pull requests merged, here's a look at the exciting features that will premiere in this next Linux kernel release.
The Linux 3.11 kernel will support kernel images compressed using the LZ4 compression algorithm.
A Linux kernel scheduler that's power-aware and aims for offering power-efficient performance has been published. The developer behind this new Linux scheduler is presently seeking other developer feedback on his set of nine patches.
The Hypertext Transfer Protocol Bis Working Group of the IETF has published a new Internet draft of the HTTP 2.0 protocol.
David Airlie has submitted the DRM subsystem pull request for the Linux 3.11 kernel that is of monster size. The Radeon DRM kernel driver is now perhaps the single biggest Linux kernel driver by code size after the merging of its huge dynamic power management code addition.
Linux wireless developers remain at work on support for 5 and 10MHz channels in order to prepare for future 802.11 standards.
Beyond Xen and KVM virtualization coming to 64-bit ARM in the Linux 3.11, there's also other ARM architecture and SoC advancements within this next major kernel release.
The sound/audio kernel driver pull request has been submitted for the Linux 3.11 merge window. The changes this time around aren't too exciting, but there's the continued bettering of the Linux audio stack.
The staging pull has been submitted for the Linux 3.11 kernel merge window and with it comes client support for Lustre, the high-performance parallel distributed file-system.
The Linux 3.11 kernel that's officially just been under development since last night's 3.10 release will feature support for KVM and Xen virtualization on 64-bit ARM (AArch64) hardware.
The Linux 3.10 kernel, which yields the biggest changes in years, has been officially released this Sunday evening.
