Description

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.

---

Main features

• Preemptive Full Tickless Kernel at 500Hz w/ Tuned CPU Core Scheduler.
• 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.
  • le9's file mappings under memory pressure protection.
  • Futex WAIT_MULTIPLE implementation for Proton Fsync support.
  • Futex2 interface compatible w/ Proton Experimental [5.12].
  • Google's Multigenerational LRU Framework [5.12].
  • Google's BBRv2 TCP congestion Control.
  • Paragon's Software NTFS3 Driver [as module: ntfs3].
  • PCIe ACS Override for bypassing IOMMU groups support.
  • Graysky's additional CPU optimizations for GCC / Clang.
  • Clear Linux patchset [partial].
  • ZSTD compression for modules support.
  • Android Ashmem and Binder IPC Driver as module for Anbox.
  • Updated ZSTD library for bug fixes and r/w performance compression improvements on Btrfs, F2FS, SquashFS, pstore, initramfs and vmlinuz.
• Kernel package for compatibility with the Fedora® Linux distribution
• GPLv2 license. Can be built for any distribution or purpose.

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
