How Kernel Executors Dispatch Compute to Hardware
Kernel executors route compiled kernels to devices and manage dependencies. Learn how OpenCL queues, PyTorch dispatch, and backend delegates actually work.

How Linux Maps Hardware to Kernel Drivers
Use lspci, lsusb, lsmod, modinfo, and sysfs to identify bound, loaded, built-in, and missing Linux drivers, then trace probe failures with confidence.
Linux on Surface Book: Install the Right Kernel First
The linux-surface kernel makes Surface Book hardware work on Linux. Learn which patches you need, how to verify installation, and what still breaks.
Build eBPF on ARM: Check the Kernel Before Clang
eBPF portability depends on the target kernel, not just the CPU. This guide covers clang, libbpf, CO-RE, BTF, verifier checks, and ARM loading.
CONFIG_BPF_SYSCALL: The Kernel Flag eBPF Programs Need
CONFIG_BPF_SYSCALL compiles the bpf() syscall into your kernel, the single entry point every eBPF program load and firewall rule requires to work.
Preverify eBPF Programs in CI Before Kernel Load
Run the kernel verifier off-device during CI to catch eBPF rejections early. Learn verifier basics, log reading, BTF fixes, and troubleshooting methods.
Make Menuconfig: Configure Linux Kernel Features Safely
The make menuconfig workflow helps you safely edit Linux kernel features, modules, and dependencies while avoiding common source-tree and ncurses errors.
Enable Kernel CONFIG Options: What to Know First
Stop looking for CONFIG_HAVE_EBPF_JIT in menuconfig. Stop looking for CONFIG HAVE EBPF JIT in menuconfig. It describes a marker, not a feature you switch on.
LKML Guide: Read the Linux Kernel Mailing List Right
LKML is where kernel patches get reviewed and merged. Learn to search lore.kernel.org, report bugs correctly, and follow threads to actual fixes.
How Kconfig Controls Linux Kernel Build Options
Kconfig manages tens of thousands of kernel build dependencies through a declarative language, menu system, and.config file that determines what gets compiled.
eBPF for Windows: Network Filtering and Observability
Windows eBPF is production-ready for network filtering and observability, but runs through its own verifier and hooks – not recompiled Linux bytecode.
How to Contribute to Linux: Start With Documentation
Master Linux kernel contributions by starting small: documentation fixes and checkpatch cleanups teach the workflow without breaking production systems.
