Highlights include rumble support for the latest Xbox controllers, Apple M2 CPU PMU support, Wi-Fi 7 (EHT) mesh support, improved support for Qualcomm Snapdragon platforms, a new driver for Novatek touch controllers, support for the Lenovo Yoga Book X90F 2-in-1 tablet, Hyper-V VTL mode support, and Wi-Fi support for Apple M1 Pro/Max devices. That side was probably a bit unlucky, in that it came in as I was looking at x86 issues anyway, and so I looked at it quite a bit, and had enough reservations that I asked for a couple of fairly big re-organizations.”

Linus Torvalds writes in his announcement post that “the one feature that didn’t make it was the x86 shadow stack code. Unfortunately, the long-awaited Shadow Stack hardware security feature didn’t make it in this release. The two-week merge window for Linux kernel 6.4 is now closed and the first Release Candidate is available to download from Linus Torvalds’ git tree or the website for early adopters, system integrators, and bleeding-edge users who want to get a glimpse of what’s about to be included in the final release.Īpart from various new features like Intel LAM (Liniar Address Masking) support, user events for tracing, or the ability for the machine keyring used for Machine Owner Keys (MOK) to store only CA-enforced keys, Linux 6.4 will come with greater hardware support through new and updated drivers. Two weeks have passed since the release of Linux kernel 6.3 and the opening of the merge window for the next kernel series, Linux 6.4, and now, Linus Torvalds released the first RC (Release Candidate) milestone for public testing.
