Description
|
|
-----------
|
|
|
|
This is the README file for the Interphase PCI ATM (i)Chip IA Linux driver
|
|
source release.
|
|
|
|
The features and limitations of this driver are as follows:
|
|

|
- Only AAL5 is supported.
|
|
- Supports setting of PCR on the VCs.
|
|
- Multiple adapters in a system are supported.
|
|
- All variants of Interphase ATM PCI (i)Chip adapter cards are supported,
|
|
including x575 (OC3, control memory 128K , 512K and packet memory 128K,
|
|
512K and 1M), x525 (UTP25) and x531 (DS3 and E3). See

Before You Start

|
Installation
|
|
------------
|
|
|
|
1. Installing the adapters in the system
|
|
To install the ATM adapters in the system, follow the steps below.
|
|
a. Login as root.
|
|
b. Shut down the system and power off the system.
|
|
c. Install one or more ATM adapters in the system.
|
|
d. Connect each adapter to a port on an ATM switch. The green 'Link'
|
|
LED on the front panel of the adapter will be on if the adapter is
|
|
connected to the switch properly when the system is powered up.
|
|
e. Power on and boot the system.
|
|
|
|
2. [ Removed ]
|
|
|
|
3. Rebuild kernel with ABR support
|
|
[ a. and b. removed ]
|
|
c. Reconfigure the kernel, choose the Interphase ia driver through "make
|
|
menuconfig" or "make xconfig".
|
|
d. Rebuild the kernel, loadable modules and the atm tools.
|
|
e. Install the new built kernel and modules and reboot.
|
|
|
|
4. Load the adapter hardware driver (ia driver) if it is built as a module
|
|
a. Login as root.
|
|
b. Change directory to /lib/modules/<kernel-version>/atm.
|
|
c. Run "insmod suni.o;insmod iphase.o"
|
|
The yellow 'status' LED on the front panel of the adapter will blink
|
|
while the driver is loaded in the system.
|
|
d. To verify that the 'ia' driver is loaded successfully, run the
|
|
following command:
|
|
|
|
cat /proc/atm/devices
|
|
|
|
If the driver is loaded successfully, the output of the command will
|
|
be similar to the following lines:
|
|
|
|
Itf Type ESI/"MAC"addr AAL(TX,err,RX,err,drop) ...
|
|
0 ia xxxxxxxxx 0 ( 0 0 0 0 0 ) 5 ( 0 0 0 0 0 )
|
|
|
|
You can also check the system log file /var/log/messages for messages
|
|
related to the ATM driver.
|
|
|
|
5. Ia Driver Configuration
|
|
|
|
5.1 Configuration of adapter buffers
|
|
The (i)Chip boards have 3 different packet RAM size variants: 128K, 512K and
|
|
1M. The RAM size decides the number of buffers and buffer size. The default
|
|
size and number of buffers are set as following:
|
|
|
|
Total Rx RAM Tx RAM Rx Buf Tx Buf Rx buf Tx buf
|
|
RAM size size size size size cnt cnt
|
|
-------- ------ ------ ------ ------ ------ ------
|
|
128K 64K 64K 10K 10K 6 6
|
|
512K 256K 256K 10K 10K 25 25
|
|
1M 512K 512K 10K 10K 51 51
|
|
|
|
These setting should work well in most environments, but can be
|
|
changed by typing the following command:
|
|
|
|
insmod <IA_DIR>/ia.o IA_RX_BUF=<RX_CNT> IA_RX_BUF_SZ=<RX_SIZE> \
|
|
IA_TX_BUF=<TX_CNT> IA_TX_BUF_SZ=<TX_SIZE>
|
|
Where:
|
|
RX_CNT = number of receive buffers in the range (1-128)
|
|
RX_SIZE = size of receive buffers in the range (48-64K)
|
|
TX_CNT = number of transmit buffers in the range (1-128)
|
|
TX_SIZE = size of transmit buffers in the range (48-64K)
|
|
|
|
1. Transmit and receive buffer size must be a multiple of 4.
|
|
2. Care should be taken so that the memory required for the
|
|
transmit and receive buffers is less than or equal to the
|
|
total adapter packet memory.
|
|
|
|
5.2 Turn on ia debug trace
|
|
|
|
When the ia driver is built with the CONFIG_ATM_IA_DEBUG flag, the driver
|
|
can provide more debug trace if needed. There is a bit mask variable,
|
|
IADebugFlag, which controls the output of the traces. You can find the bit
|
|
map of the IADebugFlag in iphase.h.
|
|
The debug trace can be turn on through the insmod command line option, for
|
|
example, "insmod iphase.o IADebugFlag=0xffffffff" can turn on all the debug
|
|
traces together with loading the driver.
|
|
|
|
6. Ia Driver Test Using ttcp_atm and PVC
|
|
|
|
For the PVC setup, the test machines can either be connected back-to-back or
|
|
through a switch. If connected through the switch, the switch must be
|
|
configured for the PVC(s).
|
|
|
|
a. For UBR test:
|
|
At the test machine intended to receive data, type:
|
|
ttcp_atm -r -a -s 0.100
|
|
At the other test machine, type:
|
|
ttcp_atm -t -a -s 0.100 -n 10000
|
|
Run "ttcp_atm -h" to display more options of the ttcp_atm tool.
|
|
b. For ABR test:
|
|
It is the same as the UBR testing, but with an extra command option:
|
|
-Pabr:max_pcr=<xxx>
|
|
where:
|
|
xxx = the maximum peak cell rate, from 170 - 353207.
|
|
This option must be set on both the machines.
|
|
c. For CBR test:
|
|
It is the same as the UBR testing, but with an extra command option:
|
|
-Pcbr:max_pcr=<xxx>
|
|
where:
|
|
xxx = the maximum peak cell rate, from 170 - 353207.
|
|
This option may only be set on the transmit machine.
