The HEPC3 Linux Kernel Driver

The Linux kernel module hepc3 is a character device driver which enables the kernel to support up to eight of Hunt Engineering's HEPC3, HEPC4 (standard PCI) or HECPCI1 (CompactPCI) TIM40 DSP motherboards.

The driver supports both comports A and B. For comport A, the boards can act as PCI Bus Masters, which increases the data transfer rate and reduces the cpu load. Comport B uses an interrupt-driven mode, which is also selectable for port A. The JTAG port is not supported, and as I do not have the necessary hard- and software, it is not likely that I will add it in the future. The driver and all accompanying documentation is

Prerequisites

To install the driver you will need

the file hepc3-1.1.0.tar.gz (see the "Download" section, below). New versions of the driver will follow this naming scheme;
a Linux system with kernel version 2.0.x or 2.2.x. Late 2.1.x and early 2.3.x development kernels may also work, but this is not tested, as well as using it with 2.4.x kernels. Please note that the driver has only been tested with Linux/Intel and LinuxPPC. Other Linux/PCI platforms (e.g. Alpha) should also work. Please mail me your experiences;
module support in the kernel, the kernel header files, the gcc, and the module utilities (insmod and friends);
proc filesystem support is highly recommended but not necessary.

Download

The driver and documentation is available from the Metalab (aka SunSite) archive in the directory /pub/linux/kernel/misc-cards. If possible, use a mirror close to you instead of the original site.
