- ATM (i)Chip IA Linux Driver Source
---------------------------------------------------------------------------------

-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:
- - A single VPI (VPI value of 0) is supported.
- - Supports 4K VCs for the server board (with 512K control memory) and 1K
- VCs for the client board (with 128K control memory).
- - UBR, ABR and CBR service categories are supported.
- - 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
- http://www.iphase.com/
- for details.
- - Only x86 platforms are supported.
- - SMP is supported.

-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.
