POWER On-Chip Controller Driver Coming For Linux 4.21

The IBM POWER On-Chip Controller (OCC) driver is queued for inclusion in the next version of the Linux kernel. This on-chip controller driver collects sensor data from the system and processor, including temperature and power metrics, and exposes that to the user as well as handling thermal/power management tasks.

Hands On With The Most Open-Source, High-Performance System For 2018

While there are several vendors working on open-source hardware systems with goals of fully open designs and open-source software down to the firmware, there is only one vendor that has achieved that mission while delivering server/workstation class performance as we approach the end of 2018... Raptor Computing Systems' Talos II. We finally have this dual POWER9 system in our labs for some interesting benchmarks ahead.

Apple's New Hardware With The T2 Security Chip Will Currently Block Linux From Booting

Apple's MacBook Pro laptops have become increasingly unfriendly with Linux in recent years while their Mac Mini computers have generally continued working out okay with most Linux distributions due to not having to worry about multiple GPUs, keyboards/touchpads, and other Apple hardware that often proves problematic with the Linux kernel. But now with the latest Mac Mini systems employing Apple's T2 security chip, they took are likely to crush any Linux dreams.

SiFive Unleashes New 7-Series RISC-V Cores With Better Performance

SiFive this week announced their 7-Series RISC-V cores with the 32-bit E7, 64-bit S7, and 64-bit U7 series. These new RISC-V parts aren't yet capable of running up against the fastest ARM Cortex CPU cores available today, but they are much more powerful than the previous-gen SiFive cores.

Linux Kernel Developers Begin Figuring Out Vendor-Specific RISC-V Code

With the increasingly popular RISC-V open-source processor instruction set architecture (ISA), there is the possibility for vendor-specific instruction set extensions. At this point the kernel has no infrastructure in place for its RISC-V port to allow for such bits, but that is being worked on as part of bringing up AndeStar RISC-V CPUs under the Linux kernel.

PCI Peer-To-Peer Support Merged For Linux 4.20~5.0

The recently covered PCI peer-to-peer memory support for the Linux kernel has indeed landed for the 4.20~5.0 kernel cycle. This is about PCI Express devices supporting peer-to-peer DMA that can bypass the system memory and processor via a standardized interface.

The Next Linux Kernel Will Further Fend Off Buggy EFI Firmware

The EFI support code within the mainline Linux kernel continues to be improved upon. While EFI firmware has matured in the past few years to become more reliable, there still are systems/motherboards shipping with various bugs. One of the additions for this next kernel release will better handle rare cases where buggy firmware could hang the kernel.

LG Gram Laptops To Be Better Supported By The Next Linux Kernel

While LG isn't often thought of as a laptop manufacturer, their Gram laptop line-up has recently been making some waves. The LG Gram laptops are powered by Intel Core CPUs and are designed to be slim and sleek yet durable. With the next Linux kernel (4.20~5.0), they should be better supported should you want to wipe the default Microsoft Windows installation.
