Tiger Lake + Renoir On Ubuntu Linux For Battery vs. AC Performance

Given the recent Intel presentation alleging AMD Ryzen laptop performance being worse on battery relative to the AC vs. battery performance seen with Intel EVO notebooks featuring Tiger Lake processors, I ran a mini comparison on my side to see whether there is any merit to Intel's information when testing under Ubuntu Linux.

Linux READFILE System Call Revived Now That It Might Have A User

Earlier this year we mentioned Greg Kroah-Hartman working on a new READFILE system call. The goal of this new syscall is for reading small and medium files more efficiently by having one call to read a file straight into a buffer without having to use the separate open/read/close system calls. It's looking like that system call is back on the table and could be mainlined now that there's a possible user.

Valve Now Funding Blumenkrantz - Zink OpenGL-On-Vulkan To Continue

Longtime open-source developer Mike Blumenkrantz who has been an Enlightenment developer for many years and was working for Samsung's Open-Source Group prior to its demise jumped into the open-source Linux graphics world this year. While being unemployed he began hacking on the Zink Gallium3D code that allows generic OpenGL acceleration over the Vulkan API. He quickly got the code to the point of OpenGL 4.6 support and quite compelling performance compared to where Zink was at earlier this year. Now it turns out he will continue with his Linux graphics adventures thanks to funding from Valve.

Intel: AMD Weak On Battery-Powered Laptop Performance - But DPTF On Linux Still Sucks

Intel held a virtual event last week to basically plead their case that AMD Ryzen laptops are coming up short on battery-powered performance compared to their own offerings. It was all Windows focused, but at least given their emphasis now on battery performance gave me another opportunity to prod over the lackluster state of Intel DPTF support on Linux with it not being pleasant out-of-the-box and one of the few areas encumbered by blobs or lack of public documentation.

Fedora 34 Might Try To Use PipeWire By Default To Replace PulseAudio/JACK

Red Hat for several years now has been working on PipeWire to overhaul audio/video stream management on Linux while being able to fill the duties currently managed by the likes of PulseAudio and JACK and being engineered with Wayland and Flatpak security in mind among other modern Linux technologies. With Fedora 34 next spring they may try to ship PipeWire by default in place of JACK, PulseAudio, and even legacy ALSA.

F2FS With Linux 5.11 To Support Casefolding With Encryption

For over one year the Flash-Friendly File-System (F2FS) has supported case-folding for optional case-insensitive file/folder support. The past number of years F2FS has also supported FSCRYPT-based file encryption. But now as we roll into 2021, support is finally seemingly ready for mainline in supporting casefolding with encryption enabled.

AMDGPU Linux Driver Seeing A Lot Of Power Saving Optimization Work

In addition to squaring away the Radeon RX 6000 series RDNA 2 support and promoting the Arcturus support for the new GPU found within the AMD MI100 accelerator, this month AMD open-source Linux driver developers have been devoting a fair amount of work towards power optimizations.

X11 Library Sees Lots Of Fixes With libX11 1.7 Release

It's been seven years since the release of libX11 1.6.0 for this central X11 library while on Friday was replaced by the libX11 1.7 series. The release is primarily made up of fixes but leading to the version bump is a new API that allows for applications to recover from I/O error conditions rather than being forced to exit.
