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...
KDE Plasma 5.18 LTS Reaches Beta With Much Better GTK App Integration
Out this morning is the first beta of KDE Plasma 5.18, which is also the project's first long-term support (LTS) release since Plasma 5.12...
GNU Guile 3.0 Released With JIT Code Generation For Up To 4x Better Performance
GNU Guile 3.0 has been released, the GNU's implementation of the Scheme programming language with various extra features. The big news with Guile 3.0 is better performance...
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...
Linux 5.6 Crypto Getting AVX/AVX2/AVX-512 Optimized Poly1305 - Helps WireGuard
Now that lead WireGuard lead developer Jason Donenfeld has managed to get this secure VPN tunnel technology queued for introduction in Linux 5.6 mainline, he's begun optimizing other areas of the kernel for optimal WireGuard performance...
Zhaoxin 7-Series x86 CPUs Mitigated For Spectre V2 + SWAPGS
When it comes to the Zhaoxin x86-compatible processors coming out of VIA's joint venture in Shanghai, their forthcoming 7-series (KX-7000) has hardware mitigations in place for some CPU vulnerabilities...
Western Digital's Zonefs File-System Looks Like It Could Be Ready To Land With Linux 5.6
Introduced last month was Zonefs as a new Linux file-system developed by Western Digital. It's looking like that new file-system could be ready for introduction with the upcoming Linux 5.6 cycle...
LLVM Developers Discuss Improved Decision Making Process
LLVM project founder Chris Lattner has proposed a new decision making process for the LLVM compiler stack around new sub-project proposals, new social policies, changes to core infrastructure, and other key changes...
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.
