Device File

/dev/ixisan

The n is the IxISA device number.

Ioctl Commands

IXISA_ADD_DEV

Add a device (card) to the device list. Example: driver/ixisaadd.c.

IXISA_DEL_DEV

Remove a device from the device list.

IXISA_GET_INFO

Retrieve a device's information, and put it to a given structure ixisa_devinfo (ixisa_devinfo_t). Example: list.c.

IXISA_READ_REG

Read a specified register's value, and put the value to a given structure ixisa_reg (ixisa_reg_t). Example: dio48/port.c.

IXISA_SET_SIG

Set interrupt signaling condictions. Example: dio48/mode2.c.

IXISA_WRITE_REG

Write a given value to a specified register. Example: dio48/port.c.

Data Structures

ixisa_devinfo_t

The data type of structure ixisa_devinfo that contains a device's id, irq, base address, and so on. Example: list.c.

ixisa_reg_t

The data type of structure ixisa_reg that contains a register's id and value. Example: dio48/port.c.

ixisa_signal_t

The data type of structure ixisa_signal that contains process id, signal id, and signaling conditions. Example: dio48/mode2.c.
