Over the past year Code Sourcery / Mentor Graphics has been working extensively on the new AMD Radeon "GCN" back-end for the GCC code compiler. With the code that is found in GCC 9 and up to now in GCC 10 hasn't supported OpenMP/OpenACC parallel programming interfaces but that could soon change with patches under review...

Open source is everywhere. It's in your computer at home, it's in your computer at work, it's on the internet, and a lot of it is managed with Git. Because Git is decentralized, many people also think of it as a kind of crowdsourced backup solution. The theory is that each time someone clones a Git repository to their local computer, they are creating a backup of the project's source code. If 100 people do that, then there are 100 backup copies of a repository.

Earlier this year, I was burned out. Coincidentally, at the time, I was also researching the subject of burnout. It's taken some time for me to take what I researched and experienced and put it into words.

Recently, the International Classification of Diseases classified burnout as an occupational phenomenon. It defines burnout as a "syndrome conceptualized as resulting from chronic workplace stress that has not been successfully managed."

This definition leads to many questions:

Now that Intel lifted its embargo on the "Jump Conditional Code" erratum affecting Skylake through Cascade Lake processors, while Intel's own Clear Linux was first to carry these patches they have now been sent out on the Binutils mailing list for trying to get the JCC optimization patches into the upstream Binutils/GAS code-base...

Microsoft Defender ATP Coming to Linux! What Does it Mean?  It's FOSS

Merged to the mainline Linux kernel last week was a driver providing VirtualBox guest shared folder support with the driver up to now being out-of-tree but important for sharing files between the host and guest VM(s). While the driver was part of Linux 5.4-rc7, Linus Torvalds decided to delete this driver on Tuesday...

VirtualBox SF Driver Ejected From The Linux 5.4 Kernel  Phoronix

This morning I provided a lengthy look at the performance impact of Intel's JCC Erratum around the CPU microcode update issued for Skylake through Cascade Lake for mitigating potentially unpredictable behavior when jump instructions cross cache lines. Of the many benchmarks shared this morning in that overview, there wasn't time for any gaming tests prior to publishing. Now with more time passed, here is an initial look at how the Linux gaming performance is impacted by the newly-released Intel CPU microcode for this Jump Conditional Code issue.

Of the 77 security advisories Intel is making public and the three big ones of the performance-sensitive JCC Erratum, the new ZombieLoad TAA (TSX Asynchronous Abort), and iTLB Multihit No eXcuses, there are also two fixes to their kernel graphics driver around security issues separate from the CPU woes...

Intel's Linux Graphics Driver Updated For Denial Of Service + Privilege Escalation Bugs  Phoronix

The Linux kernel has just received its mitigation work for the newly-announced TSX Asynchronous Abort (TAA) variant of ZombieLoad plus revealing mitigations for another Intel CPU issue... So today in addition to the JCC Erratum and ZombieLoad TAA the latest is iITLB Multihit (NX) - No eXcuses...

Linux Kernel Gets Mitigations For TSX Aync Abort Plus Another New Issue: iITLB Multihit  Phoronix

In addition to the JCC erratum being made public today and that performance-shifting Intel microcode update affecting Skylake through Cascade Lake, researchers also announced a new ZombieLoad side-channel attack variant dubbed "TSX Asynchronous Abort" or TAA for short...
