Ryzen CPUs On Linux Finally See CCD Temperatures, Current + Voltage Reporting
One of the few frustrations with the AMD Ryzen CPU support on Linux to date has been besides the often delayed support for CPU temperature reporting has been the mainline kernel not supporting voltage readings and other extra sensors. But that is finally changing with the "k10temp" driver being extended to include current and voltage reporting plus CCD temperature reporting on Zen 2 processors...
Retooled CentOS Build Scripts To Help Spin New Releases Quicker, More Automation
The release of CentOS 8 came several months after RHEL 8.0 and this week's release of CentOS updated against RHEL 8.1 took over two months of work. But moving forward to RHEL 8.2 and beyond, that turnaround time will hopefully be less...

LLVM 10 Adds Option To Help Offset Intel JCC Microcode Performance Impact
Disclosed back in November was the Intel Jump Conditional Code Erratum that necessitated updated CPU microcode to mitigate and with that came with a nearly across the board performance impact. But Intel developers had been working on assembler patches for helping to reduce that performance hit. The GNU Assembler patches were merged back in December while now ahead of LLVM 10.0 that alternative toolchain has an option for helping to recover some of the lost performance...

Intel's Mitigation For CVE-2019-14615 Graphics Vulnerability Obliterates Gen7 iGPU Performance
Yesterday we noted that the Linux kernel picked up a patch mitigating an Intel Gen9 graphics vulnerability. It didn't sound too bad at first but then seeing Ivy Bridge Gen7 and Haswell Gen7.5 graphics are also affected raised eyebrows especially with that requiring a much larger mitigation. Now in testing the performance impact, the current mitigation patches completely wreck the performance of Ivybridge/Haswell graphics performance.
Kubuntu Focus Offers The Most Polished KDE Laptop Experience We've Seen Yet
As we mentioned back in December, a Kubuntu-powered laptop is launching with the blessing of Canonical and the Kubuntu Community Council. That laptop, the Kubuntu Focus, will begin shipping at the beginning of February while the pre-orders opened today as well as the embargo lift. We've been testing out the Kubuntu Focus the last several weeks and it's quite a polished KDE laptop experience for those wanting to enjoy KDE Plasma for a portable computing experience without having to tweak the laptop for optimal efficiency or other constraints.

Linux In 2020 Can Finally Provide Sane Monitoring Of SATA Drive Temperatures
Here is another long overdue kernel change... For more than a decade there have been patches trying to get SATA/SCSI drive temperature monitoring working nicely within the Linux kernel but none of that work ever made it through for mainlining. That has left various user-space tools to provide the functionality, but in doing so that has required root access and not to mention the need to first install said utilities. Well, with Linux 5.6 in 2020, there is finally a proper drive temperature driver for disks and solid-state drives with temperature sensors...
Project Trident Reaches Beta For Its ZFS-Based Void Linux Powered OS
