Developers Call On Intel To Open-Source PSE Firmware As Their Newest Binary Headache

Phoronix - Fri, 12/10/2021 - 21:38
With Intel's Atom x6000E "Elkhart Lake" SoCs there is a new block called the Programmable Services Engine (PSE) that is an Arm Cortex-M7 companion core that handles various tasks. Unfortunately, with the PSE it means a new binary-only firmware module. With the Programmable Services Engine likely to come with future Intel platforms too, Coreboot developers and open-source enthusiasts are calling on Intel to now open-source this firmware to avoid having this extra binary blob and further complicating future open-source firmware efforts...

Restartable Sequences "RSEQ" Support Returning To GNU C Library

Phoronix - Fri, 12/10/2021 - 19:04
Back in 2018 for the Linux 4.18 kernel was introducing the Restartable Sequences system call for allowing faster user-space operations on per-CPU data. By avoiding atomic operations in cases like incrementing per-CPU counters, modifying per-CPU spinlocks, reading/writing to per-CPU ring buffers, and similar, Restartable Sequences can provide a performance advantage. The GNU C Library is landing its revised support for making use of this system call...

Film compositing on Linux with Natron

opensource.com - Fri, 12/10/2021 - 16:01

In film post-production, there's a phase called compositing, which puts the actual footage in a camera with footage generated purely by software. What that actually means to the compositing artist depends on the movie. Sometimes there are just a few overlays, other times there's some minor special effect like laser beams or explosions, sometimes it's a green screen, and still other times it's a little bit of everything. Most video editing applications can do basic compositing.

Reveal your source code with Jinja2 and Git

I'm a huge fan of open source.

One of the little ways I've supported the cause is by keeping my personal blog site open from the very beginning. I do this partly to let people see the history of changes behind each page. But I also do it because, when I started using Jekyll, I didn't find many open source Jekyll blogs to learn from. My hope is that keeping my website open and exposing my trials and errors will save someone else a lot of time.
