Following FUSE & CUSE, Now There Is "MUSE" For MTD In Userspace

FUSE is well known to longtime Linux users for allowing file-systems to be implemented in user-space for where a Linux kernel port isn't feasible for portability or licensing restrictions, among other factors. There is also CUSE for character devices in user-space. Now being based on FUSE, there is "MUSE" being worked on for MTD in user-space.

The Performance Impact To POWER9's Eager L1d Cache Flushing Fix

Last week a new vulnerability was made public for IBM POWER9 processors resulting in a mitigation of the processor's L1 data cache needing to be flushed between privilege boundaries. Due to the possibility of local users being able to obtain data from the L1 cache improperly when this CVE is paired with other side channels, the Linux kernel for POWER9 hardware is flushing the L1d on entering the kernel and on user accesses. Here are some preliminary benchmarks looking at how this security change impacts the overall system performance.

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.

Reiser5 Stabilizing Its Logical Volume Functionality

This New Year's Eve will mark one year since the announcement of the in-development Reiser5 file-system. While the outlook for getting Reiser5 upstreamed into the mainline kernel remains murky given the out-of-tree status of Reiser4, Edward Shishkin does continue advancing this latest Reiser file-system iteration.
