KernelLinux Firmware Blobs: What They Are, Why They Exist, and How to Manage Them
What binary firmware blobs are, why the kernel needs them, how request_firmware() loads them, version mismatches, Secure Boot interactions, supply chain provenance via the WHENCE file, IMA integrity checking, GNU Linux-libre, and how to fix missing firmware on Debian, Ubuntu, Fedora, and Arch.
KernelNVIDIA Linux Drivers: Open Modules, GSP Firmware, and the Road to Blackwell
Open kernel modules vs proprietary, how the GPU System Processor changed everything with Turing, what moved in the R560 and R590 driver series, Wayland DRM modeset, Blackwell-only open module support, Nouveau/NVK, and the Nova Rust driver entering the upstream kernel.
KernelLinux GPU Drivers: NVIDIA, AMD, and Intel Explained
How the Linux DRM subsystem connects GPU hardware to userspace: NVIDIA's open kernel module, AMD's AMDGPU and RADV stack, Intel's Xe driver transition, Wayland explicit sync via linux-drm-syncobj-v1, and the NVK Mesa path for a fully open-source NVIDIA stack. Updated for kernel 6.11+ and the 2026 driver landscape.
Kernel20 Unique Things You Can Do in Linux That Will Change How You Think About Operating Systems
Twenty kernel-level capabilities -- /proc, strace, eBPF, namespaces, cgroups, live patching, capabilities, rr, auditd, perf, and more -- that expose how the Linux kernel works at a level no other mainstream OS allows.
KernelUnderstanding the Linux Kernel Memory Model
Why your code can read stale values on one CPU while another CPU has already written the update -- and how the LKMM gives kernel developers a formal framework to reason about it, prevent it, and prove correctness.
