Linux Kernel 6.12 was released! Linus Torvalds announced<\/a> on Sunday:<\/p>\n

“No strange surprises this last week, so we’re sticking to the regular release schedule, and that obviously means that the merge window opens
\ntomorrow. I already have two dozen+ pull requests in my mailbox, kudos to all the early birds.<\/p>\n

But before the merge window opens, please give this a quick test to make sure we didn’t mess anything up. The shortlog below gives you the summary for the last week, and nothing really jumps out at me. A number of last-minute reverts, and some random fairly small fixes fairly spread out in the tree.”<\/i><\/p><\/blockquote>\n

The new kernel introduced many exciting new features. It finally merged the real-time FREEMPT_RT kernel patch<\/b>, which converts Linux into a fully preemptible kernel. Though, some Linux Distributions, including Ubuntu 22.04 LTS<\/a>, already added the patch into their own kernel builds.<\/p>\n

Kernel 6.2 adds initial support for Raspberry Pi 5<\/b> with Broadcom BCM2712 SoC. It supports for several more Snapdragon X1 laptops, such as Microsoft Surface Laptop 7 with Snapdragon X1, though there are still various limitations.<\/p>\n

As well, it adds new Wacom drawing tablet driver with high resolution wheel scrolling, touch rings with relative motions, two touch rings support. And, it can now optionally display a QR code when a Linux Kernel panic occurs.<\/p>\n

For Intel<\/b>, the new Kernel updated IFS driver with feature to help verify the health of the Xeon 6 CPU cores, added Efficiency Latency Control (ELC) for uncore driver, and, enhanced P\/E core exerience on Intel Lunar Lake.<\/p>\n

The perf tool has been updated with Last Branch Record (LBR) event logging support, and per-PMU context rescheduling that should significantly improve single-PMU performance.<\/p>\n

For Intel GPU, there’s now initial Panther Lake HDMI audio support, Xe2 graphics support out-of-the-box in Lunar Lake and Battlemage, as well as fan speed support for intel graphics card.<\/p>\n

For AMD<\/b>, the P-State driver has reworked calculations for AMD boost and MAD Preferred Core detection. Run-Time Average Power Limiting (RAPL) added AMD Family 1Ah “Zen 5” CPU detection.<\/p>\n

There are as well bus lock detection support, process isolation framework for AMDGPU, and more precise per-queue reset abilities when encountering hardware issues or buggy.<\/p>\n
