See -+ http://www.iphase.com/products/ClassSheet.cfm?ClassID=ATM -+ 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: -+ -+ Totol 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 trasmit machine. -+ -+ -+OUTSTANDING ISSUES -+------------------ -+ -+ -+ -+Contact Information -+------------------- -+ -+ Customer Support: -+ United States: Telephone: (214) 654-5555 -+ Fax: (214) 654-5500 -+ E-Mail: intouch@iphase.com -+ Europe: Telephone: 33 (0)1 41 15 44 00 -+ Fax: 33 (0)1 41 15 12 13 -+ World Wide Web: http://www.iphase.com -+ Anonymous FTP: ftp.iphase.com ---- ref/arch/sparc64/config.in Tue Feb 1 08:37:19 2000 -+++ work/arch/sparc64/config.in Wed Feb 2 20:33:04 2000 -@@ -216,6 +216,9 @@ - # bool ' FDDI driver support' CONFIG_FDDI - # if [ "$CONFIG_FDDI" = "y" ];

The followings are the change log and history: -+ -+ Bugfix the Mona's UBR driver. -+ Modify the basic memory allocation and dma logic. -+ Port the driver to the latest kernel from 2.0.46. -+ Complete the ABR logic of the driver, and added the ABR work- -+ around for the hardware anormalies. -+ Add the CBR support. -+ Add the flow control logic to the driver to allow rate-limit VC. -+ Add 4K VC support to the board with 512K control memory. -+ Add the support of all the variants of the Interphase ATM PCI -+ (i)Chip adapter cards including x575 (155M OC3 and UTP155), x525 -+ (25M UTP25) and x531 (DS3 and E3). -+ Add SMP support. -+ -+ Support and updates available at: ftp://ftp.iphase.com/pub/atm -+ -+*******************************************************************************/ -+
