Several months back was work to disable all Microsoft Remote Network Driver Interface Specification (RNDIS) drivers in the Linux kernel on the basis of being insecure and other factors. That plan of disabling the RNDIS drivers was faced by opposition around concerns of potentially disrupting USB tethering support and the like. It's been months since hearing anything about updated plans for disabling or dropping the RNDIS drivers but the Git branch was updated today for disabling this class of drivers.

TuxClocker has been in development for several years as another open-source GPU overclocking GUI for Linux. TuxClocker initially provided a Qt5-based user interface for GPU overclocking and ultimately established a D-Bus API as well with the new release. TuxClocker 1.0 was finally released today as the latest update to this Linux GPU overclocking software.

While Simultaneous Multi-Threading (SMT) isn't as common on Arm SoCs as it is in the x86 and POWER worlds, there are some SMT-capable designs like with the HiSilicon Kupeng 930 for Arm servers. HiSilicon engineers are working now to extend Linux's SMT run-time controls to work on ARM64 (AArch64).

For those curious about the power consumption of USB-C devices, there are some nifty devices out there that have a LED display and can report the voltage, Amps, Wattage, and USB power delivery protocol version of connected devices. It's a neat display but with a new POWER-Z driver coming to the Linux kernel it's possible to propagate that information from the system itself with this new driver.

While the Linux 6.6 merge window is over, sent out today were a set of x86 platform driver fixes that include adding a quirk so that the tablet mode switch event properly occurs with the new ASUS ROG Flow X16 laptop.

The LoongArch CPU port is seeing a number of new kernel features enabled with Linux 6.6 as well as seeing some new hardware features wired up such as for Loongson Binary Translation (LBT) and allowing LSX/LASX instruction use in kernel-space.

In addition to the ASUS laptop improvements for Linux 6.6 with the ASUS-WMI driver, additional feature work is on the way for future kernel versions with one of those interesting additions being support for the ASUS Screenpad. Some higher-end ASUS laptops feature a secondary screen "screenpad" on the laptops and the pending ASUS-WMI driver patch will properly support it.

Merged a few days ago for the ongoing Linux 6.6 merge window were the x86 platform driver updates, which bring a few interesting Intel/AMD laptop improvements as well as a new driver to support altering select HP BIOS settings from within the confines of Linux.

In addition to the HID updates bringing rumble for Google's Stadia controller and other gaming peripheral improvements, the input subsystem updates were sent out this week for Linux 6.6 that bring more enhancements for Linux gamers. In particular, the common XPad driver saw some additions for this next kernel version.

The sound subsystem and audio driver updates were merged last week for the ongoing Linux 6.6 merge window. Interesting about the sound work this cycle is a fair amount of work around AMD Van Gogh platforms, which so far is just the APU that's known to power Valve's Steam Deck.

The ACPI and power management updates were merged last week for the Linux 6.6 kernel.

The Linux kernel's "dimmtemp" driver allows for reporting memory temperatures with capable memory modules and when exposed by the Intel processor's PECI (Platform Environment Control Interface). Currently though the DIMM temperature driver is hard-coded to only allow reporting up to 32 DIMMs while a change queued for Linux 6.6 will extend that limit.

While Simultaneous Multi-Threading (SMT) on Intel/AMD x86_64 processors is limited to providing one additional thread per core, SMT on IBM POWER hardware can provide 4-way and even 8-way SMT for some processor models. With Linux 6.6 the /sys/devices/system/cpu/smt/control interface is being extended to allow greater control over managing partial SMT states in cases of the CPUs supporting more than 2-way SMT at Linux run-time.

Qualcomm engineers have begun rolling out a new open-source V4L2/media driver for a new Qualcomm "Iris" video accelerator hardware for video encode and decode on Qualcomm SoCs.

For processors supporting CPU performance boosting with higher performance states available beyond the base states, Linux allows toggling the boosting on a per-CPU basis. However, a new patch proposed this week would allow per-policy performance boosting where capable.

Loongson Binary Translation (LBT) support for the Chinese LoongArch CPU architecture is slated for introduction in the upcoming Linux 6.6 cycle.

Nearly a decade ago when there was more hope for the MIPS open-source ecosystem and the initial growth of lower-cost single board computers the MIPS Creator CI20 was launched by Imagination Tech. It wasn't too successful and MIPS development has since reached the end of the road, but finally with Linux 6.5 is the Bluetooth and WiFi on this MIPS single board computer going to finally be supported by the mainline kernel.

The HID subsystem updates have been submitted for the ongoing Linux 6.5 merge window. Most notable is NVIDIA contributing a Linux kernel driver six years late for their SHIELD controller.

Added to the Linux kernel back in 2020 was a community-written Corsair power supply driver for exposing various sensor data that their higher-end PSUs make available via a USB interface.

With Intel TDX and AMD SEV-SNP for better securing virtual machines on the mainline Linux kernel, memory is accepted/initialized immediately at boot time by the VMs although the capability exists to have "unaccepted memory" where that memory is only dealt with by the VMs later on or on an as-needed basis. For two years now Intel engineers have been working on this unaccepted memory support and this week posted their thirteenth iteration of these fundamental Linux kernel patches.

The Linux 1-Wire "w1" subsystem is used for supporting drivers with hardware that communicates via a single wire (plus ground) in a simple master-slave configuration The Linux kernel has drivers such as for W1 over GPIO, i2c to W1 bridge, and supporting some very old hardware. The W1 subsystem hasn't seen much work recently while for the upcoming Linux 6.5 cycle will be seeing a larger update.
