The Qualcomm Cloud AI 100 accelerator caters to a variety of edge-to-cloud industries. While the Qualcomm Cloud AI hardware isn't talked about as much as the AI accelerators from other vendors, there is the QAIC driver within the mainline Linux kernel for supporting the Cloud AI 100 along with associated open-source compiler and user-space stack. It turns out the Qualcomm Cloud AI family is growing with a Cloud AI 80 "AIC080" accelerator coming to market at a lower-cost.

If you have been trying out Linux 6.12-rc1 or a recent Linux Git snapshot and discovered your laptop's touchpad is no longer working, you are far from alone. The good news is the issue has been quickly tracked down and has led to a new input driver being reverted.

The input subsystem updates merged this week bring a number of improvements to existing drivers while adding one new input driver.

Similar to the ACPI CPUFreq and AMD/Intel P-State CPU frequency scaling driver and scaling governor benchmarks and power efficiency comparisons I routinely do on Phoronix, when recently having the Supermicro AmpereOne server in the lab with the 192-core A192-32X processor, I carried out some CPPC CPUFreq schedutil vs. performance governor benchmarks for curiosity and reference purposes while looking at the performance and power efficiency.

Patches for wiring up async device shutdown within the Linux kernel were queued via the driver core branch for the in-development Linux 6.12 kernel. However, at the last minute these asynchronous device shutdown patches were reverted so that they can be reworked and hopefully land for the Linux v6.13 kernel in the new year.

The USB/Thunderbolt subsystem updates were submitted today for the Linux 6.12 kernel merge window along with the other areas of the kernel overseen by Greg Kroah-Hartman. A new USB driver is the 9p network gadget driver that has been in development for quite a while and aims to help ease embedded Linux device development.

The Dell-WMI-Sysman driver on Linux allows for managing BIOS settings from within Linux using sysfs. This dell-wmi-sysman kernel driver supports most Dell platforms from 2018 and newer for convenient BIOS management.

The PCI changes for the in-development Linux 6.12 kernel add support for Native PCIe Enclosure Management "NPEM" as a code contribution by Intel for implementing the PCIe spec to standardize storage LEDs.

While not as exciting as some of the shiny new features for Linux 6.12 like real-time going mainline and Lunar Lake and Battlemage graphics by default, the Firewire (IEEE-1394) subsystem has seen some significant alterations this cycle. With Firewire hardware increasingly rare, the maintainer is hoping to get this Linux 6.12 code better tested by the community.

The Haiku open-source operating project known for letting the BeOS spirit live on is out with their newest monthly progress report.

With this week's announcement of the Intel Core Ultra 200V Series "Lunar Lake" processors, I've been very eager to try out the Meteor Lake successor for Linux testing. As sadly is usually the case, for delivering Linux support details and performance benchmarks around launch-time I'm typically left buying a laptop retail for Linux testing. In this case after seeing the Lunar Lake laptops announced this week and their availability, I ended up settling on the ASUS Zenbook S 14 (UX5406SA-S14.U71TB) for the initial Core Ultra 200V series Linux review.

While using the older Qualcomm Snapdragon 8xc Gen 3 (SC8280XP) SoC and not the exciting Snapdragon X1 Elite, Linux kernel patches were posted this week for enabling the Microsoft Surface Pro 9 5G to boot with the mainline kernel.

Power Profiles Daemon as the UPower project to make Linux laptop/system power profile handling via D-Bus is out with a new release. This is the Linux/open-source solution for exposing of power profiles to the Linux desktop and better managing the system state between power-saver / balanced / performance modes and other options.

The upstream Linux "oxp-sensors" driver began as a driver for supporting the sensors on the OneXPlayer handheld. With time this driver has been extended to support more handheld gaming consoles and a new patch enables support for several more devices.

Following all of the Snapdragon X1 upstream enablement work over the past number of months by Qualcomm and then DeviceTree additions emerging for enabling the likes of the ASUS Vivobook S 15, Lenovo Yoga Slim 7x, Lenovo ThinkPad T14s Gen 6, and Microsoft Surface 7, the Samsung Galaxy Book4 Edge is the newest Snapdragon X1 Elite laptop seeing Linux DT support.

In addition to the ASUS ROG Ally X revision of this handheld gaming console having more (and faster) system memory, doubling of the battery capacity, upgraded storage, improved cooling, and other refinements over the original ROG Ally gaming handheld, there is a different audio amplifier. In turn a Linux kernel patch is needed to fix-up the audio support on the ASUS ROG Ally X as well as needing to fetch a new firmware binary.

Submitted for DRM-Next last week with intentions of getting it into the Linux 6.12 kernel was a new DRM "power saving policy" property. The intent was for this new monitor/display connector property to indicate whether power saving features should be used that could compromise the experience intended by the desktop compositor. But one week later this property is now set to be removed as it's been deemed immature.

Red Hat's performance team has been working on the Tuned profile delivery software as an alternative to power-profiles-daemon on Linux systems. Fedora will be switching over to Tuned to replace power-profiles-daemon and the newest Tuned 2.24 release is now available.

While there is no shortage of consumer network attached storage (NAS) devices these days, those able to run a mainline Linux kernel, open bootloader, and other open/mainline software components is a bit more challenging. Thanks to the work of open-source developer Heiko Stuebner, the QNAP TS-433 is looking to be an interesting candidate for those wanting a nice 4-bay NAS while being able to load it with a mainline Linux kernel build and other upstream open-source software.

Ilpo Järvinen of Intel sent in a new round of x86 platform driver fixes today for the ongoing Linux 6.11 kernel cycle. This pull request has a few items worth mentioning as part of this fixes queue.

Open-source developer Tomeu Vizoso who has been working on supporting Vivante NPU IP within the reverse-engineered Etnaviv driver has been much time recently focused on enabling the Vivante NPU found within the NXP i.MX 8M Plus SoC. While not yet upstreamed, he's been successful in this effort and seeing good performance for object detection with this hardware.

Sent out today was the first batch of drm-misc-next patches of Direct Rendering Manager updates that will be targeting the Linux 6.12 kernel later in the year. Notable from this pull is introducing a new DRM Power Saving Policy for display connectors and is initially wired up for the AMDGPU kernel graphics driver.

There's been no shortage of cheap, ARM-based handheld game consoles coming to market. Given Linux on Arm tending to work better than Windows and in keeping vendor costs to a minimum, they've tended to be running Linux or Android with various open-source games/emulators. Many of the vendors have kept their Linux support downstream while with time more of these gaming handheld consoles are seeing mainline Linux support. Yet another one being worked on for mainline Linux kernel support is the GameForce Ace.

Immediately prior to the Linux 6.11-rc1 kernel being released yesterday, a set of Compute Express Link (CXL) patches were merged for the Linux kernel. There is some more CXL feature work this cycle but also notable is a documentation update as it now provides a concise look at the current state of CXL support on Linux.

For those striving for a quiet PC while having high-end specs, ASRock today announced passively-cooled Radeon RX 7900 XT and Radeon RX 7900 XTX graphics cards.

The x86 platform driver updates were merged last week for the Linux 6.11 merge window. The x86 platform drivers predominantly benefit Intel/AMD laptops on Linux but also some other x86 non-laptop hardware and then more recently also some ARM64 laptop drivers appearing in this area of the kernel.

The HID subsystem updates recently landed into the mainline Linux 6.11 kernel codebase.

This weekend the ASUS ROG Ally X began shipping as an upgraded version of the ASUS ROG Ally handheld gaming console that launched last year. The ASUS ROG Ally X is still powered by the AMD Ryzen Z1 Extreme SoC and for the most part similar to the original model but now with 24GB of LPDDR5X-7500 memory up from 16GB of LPDDR5-6400, twice as large battery capacity, 1TB of NVMe storage rather than 512GB, improved input controls, improved cooling, and other refinements. But it still is running Microsoft Windows 11 out-of-the-box.

It's not too often that the ATA pull request for a new Linux kernel merge window has much worth mentioning. With Linux 6.11 there is a change to the kernel defaults worth noting over the default SATA link power management policy. In this case most Linux distributions have been setting a better default themselves and is now a case of the upstream kernel defaults catching up.

DRM subsystem lead maintainer David Airlie recently submitted the DRM-Next pull request for merging into Linux 6.11. All of that Direct Rendering Manager (DRM) feature code has landed for the many kernel graphics/display driver updates along with changes to the few AI accelerator "accel" drivers also part of the tree. As usual, the Intel Xe/i915 and AMD AMDGPU/AMDKFD kernel drivers see a bulk of the upstream open-source graphics improvements.

Greg Kroah-Hartman described the char/misc pull request for the Linux 6.11 merge window as having "just loads of new drivers and updates." Among the new drivers is beginning to enable support for the KEBA CP500 as the latest FPGA seeing upstream kernel support.

The LoongArch CPU architecture changes were submitted and subsequently merged on Monday for the ongoing Linux 6.11 merge window. With the new kernel these Chinese processors support more kernel features for this MIPS-derived and RISC-V-inspired architecture.

Way back at the start of 2023, French fabless semiconductor company Kalray posted Linux kernel patches for a "KVX" Linux kernel port to get Linux up and running on their MPPA3-80 "Coolidge" DPU SoC with the KV3-1 CPU architecture. A year and a half later this work still is outside the Linux kernel but finally a third iteration of the KVX Linux kernel port has been posted for review.

Greg Kroah-Hartman on Friday sent out all of the USB/Thunderbolt subsystem feature updates destined for the Linux 6.11 kernel of which there are many different patches across the board.

With Linux 6.11 support for the Lenovo Yoga Slim7x and ASUS Vivobook S15 are upstreamed for some of the first Qualcomm Snapdragon X1 Elite powered laptops. But for follow-on kernel cycles you can expect yet more Snapdragon X1 Elite/Plus powered laptop support to appear with new DeviceTree additions. On Friday, Linaro engineer Konrad Dybcio sent out the patches for enabling the X1 Elite powered Lenovo ThinkPad T14s Gen 6 laptop.

With Linux 6.11 over on the Arm-focused SoC side there were three new SoCs and 59 new machines/boards added for Arm and RISC-V. The MIPS pull request was submitted overnight for this next kernel version and there is just two new SoCs being introduced.
