Given the age of the X.Org/X11 code-base security issues have become quite frequent. It was nearly a decade ago that the X.Org Server was considered a "security disaster" and a security researcher saying it's even worse than it looks. Today another batch of X.Org Server security vulnerabilities have been made public...

While the ETC2 texture compression standard is royalty-free and popular for OpenGL / GLES / Vulkan use, recent AMD Radeon GPUs and APUs have removed their native support for this alternative to the likes of ASTC and S3TC. But now in Mesa 22.0 there is emulated ETC2 support for the Radeon "RADV" Vulkan driver to in turn improve this open-source driver's Android support...

Upstreaming progress is being made on a new "HIPSPV" toolchain for AMD's HIP path so that SPIR-V kernels can be executed and ultimately allowing for execution by OpenCL drivers.

One of the Intel patch series we have been waiting to see mainlined since all the way back in 2018 is around per-client GPU metrics reporting for being able to show various GPU engine activity on a per-process basis. Every once in a while the patches have been revived but have yet to reach mainline. They recently were revved once again, leaving us hope that in 2022 we might finally see this standardized per-client/process GPU statistics reporting land in the mainline kernel...

This year there has been a lot of Linux kernel work around improving the handling of tiered memory servers, namely those with traditional system RAM augmented by Intel Optane DC persistent memory. There has been work to demote pages during reclamation to the slower persistent memory, improving NUMA balancing around such systems to optimize memory placement, transparent page placement and related work around tiered memory Linux servers...

Coming with future Intel CPUs is Trust Domain Extensions (TDX) to further enhance the security of virtual machines (VMs) and it's sounded a lot like AMD's Secure Encrypted Virtualization (SEV) in many regards and in fact now for the Linux kernel Intel is looking at leveraging some of that SEV code to allow for more code sharing between these CPU features to improve virtualization security...

The open-source Radeon Linux graphics driver work covered yesterday about a big optimization by leveraging NIR and going through that intermediate representation and relying on common NIR optimizations has now been merged into Mesa 22.0. This is a step-up from the existing open-source OpenGL driver support for old Radeon 9500 through Radeon X1000 series (R500) graphics processors. A similar conversion is also planned for the old Nouveau driver handling NVIDIA "NV30" era graphics processors too...

It's been a while since last having a hearty BSD benchmark comparison on Phoronix in part due to the latest hardware platforms generally lagging behind with how well supported they are by the various BSDs. But stemming from a Phoronix Premium supporter recently requesting some fresh BSD benchmarks, here is a look at how DragonFlyBSD 6.0.1, FreeBSD 13.0, NetBSD 9.2, and OpenBSD 7.0 are competing against various Linux distributions like CentOS, Clear Linux, and Ubuntu.

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...

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...
