Linux 6.19.9 update
Linux Kernel 6.19.9 landed with explicit boosts for AMD GPUs and Apple M1/M2/M3 support — and it introduces the EEVDF scheduler in this patch release (social briefing). The announcement suggests improved hardware enablement for Apple Silicon and AMD device drivers that could matter for on‑device ML workflows and platform stability (social briefing). (x.com)
The stable 6.19.9 tarball was published on March 19, 2026 according to the kernel.org release metadata for the 6.x stable series. (kernel.org) The stable review cycle that produced 6.19.9 included a 379‑patch series posted for review by Greg Kroah‑Hartman on March 19, 2026. (lkml.org) Mainline 6.19 moves older GCN 1.0/1.1 Radeon cards to the amdgpu driver by default and reviewers measured roughly ~30% average gains on legacy Radeon workloads in Phoronix tests, with outlets reporting up to ~40% on some R9 290/HD 7000 scenarios. (phoronix.com) (omgubuntu.co.uk) EEVDF’s mainline history is documented back to the 6.6 conversion and subsequent completion work, and 6.19.9’s commits include follow‑up scheduler fixes and LKML activity addressing avg_vruntime/place_entity regressions noted in recent patch threads. (docs.kernel.org) (lwn.net) (lkml.org) Apple‑Silicon enablement continues to rely on Asahi‑maintained patches and supporting userland work; Debian’s hardware documentation still points users to Asahi patches for M1/M2 installs, and Asahi’s m1n1 bootloader work (including a move toward Rust) remains an active upstream effort tied to recent mainline merges. (wiki.debian.org) (linuxencaja.net) (elixir.bootlin.com) Major distributors and third‑party kernels began packaging the 6.19.9 stable tag immediately: Xanmod and Zen merged v6.19.9 into their trees around March 19–20, and CachyOS published an EEVDF‑flavored 6.19.9 LTO package the week of the stable release. (dl.xanmod.org) (github.com) (packages.cachyos.org) The 6.19.9 ChangeLog and mirrors list specific stability and security fixes in this point release, including TCP constant‑time MAC comparison hardening and driver bug fixes such as ALSA hda/Realtek speaker‑pop and ACPI __iomem corrections.
