CM-iTC: Linux: Kernel
Contents
Overview
The CM-iTC is a fully-compatible x86 PC. Recent Linux kernels support most CM-iTC hardware features. CompuLab provides 2.6.38 kernel and customized patch to it. The configuration file is debian/config/i386/config.itc in the kernel sources tree.
The most significant features of interest to kernel developers are described below.
