| 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. |
