kernel-xanmod-cacule is now able to compile akmods properly since 5.12.10-xm1cacule.0 https://pagure.io/kernel-xanmod/issue/2#comment-737288 kernel-xanmod-edge will not be built using LLVM+LTO unlike the Debian-based upstream Instead, LLVM+LTO will be used to build kernel-xanmod-exptl, the experimental branch exclusive to this Copr

XanMod Kernel

Upstream GitHub

XanMod is a general-purpose Linux kernel distribution with custom settings and new features. Built to provide a stable, responsive and smooth desktop experience.

The real-time version is recommended for critical runtime applications such as Linux gaming eSports, streaming, live productions and ultra-low latency enthusiasts.

Supports all recent 64-bit versions of Fedora® Linux.

※ Note: The current proprietary NVIDIA, VirtualBox, VMware Workstation / Player and some other akmod/dkms modules builds do not officially support Clang'ed (EXPTL) and RT kernels.

  • RCU Boost for better responsiveness and lower overall system latency.
  • Full multi-core block layer runqueue requests for high I/O throughput.
  • Caching, Virtual Memory Manager and CPUFreq Governor improvements.
  • BBRv2 TCP Congestion Control + FQ-PIE Packet Scheduling and AQM Algorithm.
  • ORC Unwinder for Kernel Stack Traces (debuginfo) implementation.
  • LLVM's Clang Full LTO build available [5.12-exptl].
  • High responsiveness multitasking CacULE scheduler (SCHED_NORMAL) based on ULE interactivity score mechanism build available [5.12-cacule].
  • Real-time Linux kernel (PREEMPT_RT) build available [5.11-rt].
  • Third-party patchset available: patches
    • CK's high-resolution kernel timers (hrtimer) enhancement.

Installation Instructions

※Don't forget to install the respective -devel package if you use akmod and dkms

Enable the Copr repo:

sudo dnf copr enable rmnscnce/kernel-xanmod

And now install the kernel:

sudo dnf in kernel-xanmod-edge

if you want edge but built with LLVM+Clang with full LTO:

sudo dnf in kernel-xanmod-exptl
Regarding modules in `exptl`, you have to do this to successfully build kernel modules on `exptl` ``` # Installation sudo dnf in clang llvm lld # make sure the LLVM toolchain is installed env CC=clang LLVM=1 LLVM_IAS=1 sudo -E dnf in kernel-xanmod-exptl{,-devel} # Update sudo dnf in clang llvm lld # make sure the LLVM toolchain is installed env CC=clang LLVM=1 LLVM_IAS=1 sudo -E dnf up kernel-xanmod-exptl\* ```

if you want the variant with CacULE patches:

sudo dnf in kernel-xanmod-cacule

if you want to use LTS kernels:

sudo dnf in kernel-xanmod-lts

if you want to do RT workloads:

sudo dnf in kernel-xanmod-rt
