CustomKernels

Linux kernels engineered for your hardware.
Optimised, hardened, and supported for the long haul.

$ make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j$(nproc)

Built Around Your Workload

Every kernel option chosen deliberately — no bloat, no surprises.

Tailored Configurations

Kernel built to your exact hardware and workload. Strip unnecessary drivers and subsystems to minimise attack surface, boot time, and memory footprint.

Architecture Support

x86-64, ARM64, RISC-V, and MIPS targets. Cross-compiled toolchains and QEMU test environments provided for every supported architecture.

Performance Patches

Carefully selected patch sets — PREEMPT-RT, CFS tuning, huge-page awareness, and NUMA balancing — applied and validated before delivery.

Hardened by Default

CONFIG_HARDENED_USERCOPY, KASLR, stack canaries, and kernel lockdown mode enabled out of the box. CVE triage and security back-ports included.

Reproducible Builds

Bit-for-bit reproducible kernel images via a fully pinned build environment. Every release ships a signed SHA-256 manifest for auditability.

Long-Term Support

Aligned to upstream LTS branches with a defined maintenance window. Back-port policy and EOL dates published upfront so you can plan your roadmap.
