Intel Panther Lake / Arc B390 Linux Benchmarks Still Coming

Phoronix | Jan. 26, 2026, 12:23 p.m. | Original

Ahead of tomorrow's official availability of new Intel Core Ultra Series 3 " Panther Lake " laptops, the review embargo lifted on Panther Lake and its much anticipated Arc B390 graphics. There have been several Windows 11 reviews of Panther Lake out today, but what about Linux?

Linux performance benchmarks of Intel Panther Lake as well as support/compatibility details are still coming. While Intel talked recently of sending out a Panther Lake laptop for review at Phoronix, so far I haven't seen any device

Revisiting The Linux 6.19 Performance With "NEXT_BUDDY" Now Disabled

Phoronix | Jan. 26, 2026, 10:24 a.m. | Original

Back at the start of the Linux 6.19 kernel cycle I ran benchmarks showing some scheduler performance regressions with the new kernel . Fortunately, two weeks out from the Linux 6.19 stable release, merged this weekend was disabling the scheduler's NEXT_BUDDY feature due to performance regressions . Here are some fresh benchmarks looking at the latest Linux 6.19 Git state with/without NEXT_BUDDY and comparing it to Linux 6.18 stable for reference.

The NEXT_BUDDY feature that

Patch Proposed To Allow Toggling Linux Kernel VT Support At Boot Time

Phoronix | Jan. 26, 2026, 9:07 a.m. | Original

A patch causing a healthy technical debate today on the Linux kernel mailing list would allow the kernel virtual terminal "VT" support to be enabled/disabled at boot time rather than being limited to the current CONFIG_VT build-time option.

Jocelyn Falempe of Red Hat proposed the 18 line patch to allow building the kernel with CONFIG_VT enabled but then at boot time be able to enable/disable it with either the vt.enable=1 or vt.enable=0 boot options.

Initial AMD GFX13 Target Merged To LLVM 23 Git - Presumably RDNA5

Phoronix | Jan. 26, 2026, 8:23 a.m. | Original

Added to the LLVM 23 Git codebase minutes ago is a pull request adding the initial AMDGPU GFX13 target for their next-generation graphics core IP. AMD GFX13 is presumably for RDNA5.

AMD GFX12 is for RDNA4 GPUs and there has also been the GFX12.5 / GFX1250 IP as a possible "RDNA4 refresh" while merged to LLVM Git this morning is an initial GFX13 target.

For now this initial AMDGPU GFX13 target

AMDGPU Patches Updated For HDMI Gaming Features On Linux With Radeon Graphics

Phoronix | Jan. 26, 2026, 6:20 a.m. | Original

A patch series posted last week for the open-source AMDGPU kernel driver implements HDMI Variable Rate Refresh "VRR" and other gaming features for HDMI displays . With the HDMI Forum blocking HDMI 2.1 open-source support , these HDMI gaming features for the AMDGPU driver were developed via trial-and-error and the limited public knowledge available. A second iteration of these patches are now available for testing.

Tomasz Pakuła posted a second version of the AMDGPU Linux driver patches providing VRR fixes and these HDMI Gaming

LG Gram Style 14 Laptop To See Working Speaker Support With Linux 7.0

Phoronix | Jan. 26, 2026, 5:52 a.m. | Original

For the Intel-powered LG Gram Style 14 laptop one of the Linux support caveats is the internal speakers not working properly under Linux, but with a patch expected for the upcoming Linux 6.20~7.0 kernel cycle it will finally fix the laptop speaker support for one of the laptop models in this series.

It doesn't take much searching to find Linux users reporting broken speaker support for the LG Gram Style 14 laptop. An issue going on for years while some users have luck with

ASRock Rack PAUL PCIe IPMI Card Sees DT Patches For The Mainline Linux Kernel

Phoronix | Jan. 26, 2026, 5:38 a.m. | Original

ASRock Rack's PAUL is a low-profile PCIe IPMI card built around the widely-used ASPEED AST2500 controller for providing IPMI/BMC capabilities for any platform. New patches provide mainline Linux kernel support for ASRock Rack PAUL with the necessary Device Tree bits.

ASRock Rack's PAUL is similar to the ASUS "Kommando" IPMI Expansion Card that also saw recent Linux DT patches for enabling a mainline kernel to run on that ASUS IPMI card. ASRock Rack PAUL powered by the AST250

New Patches Aim To Lower Linux Memory Use For Swap, Slightly Improve Performance

Phoronix | Jan. 26, 2026, 5:27 a.m. | Original

Kairui Song of Tencent sent out a new patch series overnight working on enhancing the Linux kernel's swap code. With the patches there are some memory savings -- and more on the way -- while also providing for slightly faster performance.

The patch series removes the static "swap_map" and uses the swap table for the swap count directly. This conserves around 30% memory use for the static swap metadata, which amounts to 256MB of memory when mounting a 1TB swap device.

Several New X.Org Libraries See 2026 Releases

Phoronix | Jan. 25, 2026, 8:14 p.m. | Original

While we wait to see what comes of the new X.Org Server Git branch plans and a possible X.Org Server 26.1 release , several X.Org libraries saw new point releases this weekend. These seldom-updated libraries saw new releases to ship various build fixes and other minor improvements.

Alan Coopersmith of Oracle's Solaris team and long-time X.Org release wrangler spent a lot of time this weekend shipping new upstream X.Org library updates. The new releases this weekend include:

Linux 6.19-rc7 Released With Kernel Continuity Plan, A Few Important Fixes

Phoronix | Jan. 25, 2026, 5:29 p.m. | Original

The Linux 6.19 kernel remains on track for its official release two weeks from today, with the extra RC being baked in due to the end of year holidays. Out today is Linux 6.19-rc7 with a few changes worth highlighting for the week.

With Linux 6.19-rc7 there is the newly-merged continuity planning for the Linux kernel development should Linus Torvalds' official upstream Git kernel repository ever become inaccessible or other unforeseen circumstances arise. An important fix/revert
