Back in 2019 after various speculation-based CPU vulnerabilities began coming to light, Amazon engineers proposed process-local memory allocations for hiding KVM secrets. They were striving for an alternative mitigation for vulnerabilities like L1TF by essentially providing some memory regions for kernel allocations out of view/access from other kernel code. Amazon engineers this week laid out a new proposal after five years of ongoing Linux kernel improvements for MM-local memory allocations for dealing with current and future speculation-based cross-process attacks...

Intel software engineers have been upstreaming the Lunar Lake support for Linux a number of months already and the basics appear in good shape, aside from the Xe2 graphics enablement being an ongoing matter. Much of the rest of the core functionality has appeared to be in good shape ahead of Lunar Lake laptops launching in Q3, but it seems there have been a few missing power management related bits...

Newly merged patches for Mesa 24.2 slightly enhance the default out-of-the-box build experience for the open-source OpenGL and Vulkan drivers on POWER/PowerPC platforms...

While not talked about as much as the likes of the Intel Gaudi accelerators with their upstream Habana Labs kernel driver or the AMD Instinct MI300 series with their open-source upstream support too, back in 2022 Qualcomm did post an open-source kernel driver for their Cloud AI accelerator. That was followed by an open-source compiler and user-space stack and in turn the QAIC driver was upstreamed into the accelerator (accel) subsystem last year with Linux 6.4...

Intel on Wednesday released version 1.5 of their Linux NPU driver, their user-space driver component for Linux systems in enabling the neural processing unit found with Core Ultra "Meteor Lake" processors and newer.

The upstream ROCm code on GitHub as of writing continues pointing only to the prior ROCm 6.1.2 software but there is now a Radeon Software for Linux packaged driver offering up ROCm 6.1.3...

Building off the Xe2 foundation in place for the Lunar Lake integrated graphics, more recently Intel's open-source Linux graphics driver engineers have begun pushing out code focused on enabling the Xe2-based Battlemage discrete GPUs as the successor to the DG2/Alchemist hardware. That enablement work remains ongoing and with the upcoming Linux 6.11 kernel cycle the important fundamental milestone is being crossed of actually being able to drive a connected display/monitor by a Battlemage GPU...

Sent out this week is the second iteration of the stubbed Nova kernel driver and the associated Rust language DRM subsystem abstractions...

For those running the command "systemd-tmpfiles --purge" and think that this command just deletes your temporary files, think again and watch out. In reality it will delete all files and directories created by a tmpfiles.d entry... Including the /home that is created by systemd-tmpfiles' home.conf. With users being bitten in recent days by this behavior when they were just expecting tmp files to be removed, systemd 256.1 is now available and does have a change to avoid inadvertently deleting your all-important home directory...

The Linux kernel "FORCE_NR_CPUS" Kconfig option has been around a few years to force the number of CPU cores the kernel expects in order to allow for better compiler optimizations. When building a kernel targeted for a specific device/platform with a given number of CPU cores, the compiler can optimize CPU mask routines and shrink the size of the resulting kernel image rather than having to accommodate up to a dynamic upper-limit for the number of CPU cores to be found at boot time. Linus Torvalds himself has turned to demoting this CONFIG_FORCE_NR_CPUS option further to avoid confusion...

While Intel Panther Lake processors aren't expected until at least mid-2025, with Intel open-source Linux engineers already having much of the Arrow Lake and Lunar Lake support in order (the main Lunar Lake area still being ironed out is the Xe2 graphics), work is slowly beginning on upstreaming Panther Lake support...
