| - | This is the user documentation for the flink kernel modules. They offer drivers capabilities to communicate with various hardware interfaces. For more information about the inner workings see [[https:// | ||
| - | |||
| - | ===== Overview ===== | ||
| - | When flink is used on a Linux based system the flink library in userspace communicates with the hardware by means of several kernel modules. The basic module is '' | ||
| - | |||
| - | ===== Requirements ===== | ||
| - | * Linux based operating system | ||
| - | * GCC 4.6 or newer | ||
| - | * GNU make | ||
| - | |||
| - | ===== Building ===== | ||
| - | * Clone git repository: < | ||
| - | * Choose the target plattform and find its appropriate kernel configuration together with the kernel headers. Find more help about this in [[https:// | ||
| - | * Build for the host plattform with: < | ||
| - | * Build for a plattform different from the host with: < | ||
| - | * '' | ||
| - | * '' | ||
| - | * '' | ||
| - | * The makefile will switch to the kernel directory, read the current configuration and compile all necessary flink kernel modules for the choosen target plattform. | ||
| - | * Use '' | ||
| - | |||
| - | ===== Installation ===== | ||
| - | * Move new kernel modules into the default location to ''/ | ||
| - | * Load each module with '' | ||
| - | * If dependency files were created beforehand its better to use < | ||
| - | * Some kernel module must be loaded with the appropriate arguments according to the target board specifications (see below) | ||
| - | |||
| - | ===== Module Parameters ===== | ||
| - | Determine the availabe parameters for each kernel module with the command '' | ||

| - | Busses like //PCI// have discoverability built into them. Any device connected to such a bus can tell the system, what kind of device it is and what resources it uses. On the //local plus bus// this is not possible. Therefore, you must provide the total device memory length when loading the module. This length is determined by the number and types of the subdevices implemented in VHDL, see [[software: | ||
