Linus Torvalds Decides To Land NVIDIA RTX 30 "Ampere" Support In Linux 5.11

While new feature code is normally not allowed in past the end of the merge window for a given Linux kernel release cycle, Linus Torvalds has decided to merge the newly-published open-source driver code for the NVIDIA GeForce RTX 30 "Ampere" graphics cards for the Linux 5.11 kernel that will debut as stable in February.

Changing One "If" To "While" Caused An Unexpected Shift In A Kernel Benchmark This Week

Several months back you may recall that Linux 5.9 kernel regression we noted that in turn was bisected to code introduced by Linus Torvalds around page lock fairness. That was ultimately worked out in time with allowing a control over the page lock (un)fairness to address the regressed workloads while being fair enough to satisfy his original change. But now this week for Linux 5.11, Linus Torvalds has again altered the behavior. It then ended up causing a PostgreSQL database server performance regression but fortunately any impact should be very minimal and hopefully not appearing in any real-world situation.

Linux Kernel Developers Discuss Dropping A Bunch Of Old CPUs

With Linux 5.10 having shipped as the latest Long Term Support (LTS) release to be maintained for at least the next five years, a discussion has begun over dropping a number of old and obsolete CPU platform support currently found within the mainline kernel. For many of the architectures being considered for removal they haven't seen any new commits in years but as is the case once proposals are made for them to be removed there are often passionate users wanting the support to be kept.

11 Features That Didn't Make It In 2020 For Linux 5.11

For as great as Linux 5.11 is with its new features, there is also some prominent material that has yet to be upstreamed into the mainline kernel -- some of which is likely to hit in 2021 while other changes have less likely ambitions for mainline.

Linux To Report MIPS Vulnerabilities But They Often Go Unreported Or Dead Vendors

The Linux kernel with the likes of ARM and x86 hardware leverage kernel infrastructure for reporting their relevant CPU security mitigations while only now the MIPS kernel code is seeing work to report such vulnerabilities. However, on the MIPS front it's more difficult with some vendors not publicly acknowledging vulnerabilities and other cases of MIPS hardware vendors no longer producing the hardware in question or even in business.

Radeon RX 6800 XT Seeing Some Slight Gains With Linux 5.11

While the Linux 5.11 merge window is only half-way through with prominent pull requests like the DRM / graphics driver updates already have been merged some of the testing has already begun at Phoronix of this new kernel. With the Radeon RX 6800 XT "RDNA 2" graphics continuing to mature, we are seeing slight uplift in some benchmarks when moving from Linux 5.10 stable to Linux 5.11 Git.

Linux Continues Crackdown On User-Space Poking CPU MSRs

The Linux kernel this year has seen new safeguards and efforts aiming to have user-space reduce their arbitrary poking of CPU machine specific registers (MSRs) in the name of security and other handling concerns. That effort has continued on with the Linux 5.11 cycle.

GNU Linux-libre 5.10-gnu After A Busy Time Deblobbing

Following yesterday's release of the Linux 5.10 LTS kernel the GNU folks have released their "GNU Linux-libre 5.10-gnu" downstream that is the Linux kernel but without support for loading proprietary modules as well as preventing closed-source firmware binaries from being loaded on the system and related steps in the name of free software.

Linux 5.10 LTS Released As One Of The Biggest Kernel Releases In A While

As expected, Linus Torvalds today officially released Linux 5.10. Besides being the last kernel release of 2020, this is a significant milestone in that it's also a Long Term Support (LTS) kernel to be maintained for at least the next five years and also is a huge kernel update in general with many new features.
