Device ID

PCI_1202

Device File

/dev/ixpcin

The n is the IXPCI device number.

ioctl Commands

IXPCI_GET_INFO
Retrieve a device's information, and put it into the ixpci_devinfo (ixpci_devinfo_t) structure. Example: list.c.
IXPCI_READ_REG
Read a specified register's value, and put the value into the ixpci_reg (ixpci_reg_t) structure. Example: ixpci1202/dio.c
IXPCI_WRITE_REG
Write a given value to a specified register. Example: ixpci1202/dio.c
IXPCI_RESET
Reset device.Example: ixpci1202/reset.c
IXPCI_TIME_SPAN    IXPCI_BLOCK    IXPCI_DELAY    IXPCI_WAIT
IXPCI_TIME_SPAN uses the 8254 counter-2 to be the machine-indepent-timer by the internal 8 MHz clock. Command will be blocked before the countering has finished. The maximum counter value is 8190 micro-seconds. IXPCI_TIME_SPAN, IXPCI_BLOCK, IXPCI_DELAY, and IXPCI_WAIT all are identical. Example: ixpci1202/time_span.c.

Data Structures

ixpci_devinfo_t
The data type of structure ixpci_devinfo which contains a device's id, base address, and so on. Example: list.c
ixpci_reg_t
The data type of structure ixpci_reg which contains a register's id and value. Example: pci1202/port.c
