This is not your typical dry academic textbook. It’s a hands-on, step-by-step guide aimed at hackers, tinkerers, and developers who want to demystify kernel programming.

Like the traditional Berkeley Packet Filter, eBPF provides an interface to kernel-level events, which then launch eBPF programs that run in a secure virtual machine in the Linux kernel.

To understand the book, you already should be familiar with IP networking protocols and the basics of kernel programming for Linux or another UNIX operating systems.

The work queue interface has been a part of the kernel since 2.5.41. In that time, a large number of drivers and subsystems have made it their method of deferring work.

OpenCL 2.2 incorporates the OpenCL C++ kernel language for significantly enhanced parallel programming productivity.
