+ READ ME FISRT
+ ATM (i)Chip IA Linux Driver Source
+--------------------------------------------------------------------------------
+ Read This Before You Begin!
+--------------------------------------------------------------------------------
+
+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.
