When a module using the -following command will suffice for most: - -# modprobe sktr - -This will produce output similar to the following: (Output is user specific) - -sktr.c: v1.01 08/29/97 by Christoph Goos -tr0: SK NET TR 4/16 PCI found at 0x6100, using IRQ 17. -tr1: SK NET TR 4/16 PCI found at 0x6200, using IRQ 16. -tr2: SK NET TR 4/16 ISA found at 0xa20, using IRQ 10 and DMA 5. - -Now just setup the device via ifconfig and set and routes you may have. After -this you are ready to start sending some tokens. - -Errata: -For anyone wondering where to pick up the SysKonnect adapters please browse -to http://www.syskonnect.com - -This driver is under the GNU General Public License. Its Firmware image is -included as an initialized C-array and is licensed by SysKonnect to the Linux -users of this driver.

This enables ibmtr_probe in ibmtr.c to find the card and - configure it as though it was a normal ISA and/or PnP card. - - CHANGES - - v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com) - Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c - - v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com) - Updated to version 2.2.7 to match the first version of the kernel - that the modification to ibmtr.c were incorporated into. - - v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com) - Address translation feature of PCMCIA controller is usable so - memory windows can be placed in High memory (meaning above - 0xFFFFF.) - -======================================================================*/ - -#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include - -#include -#include - -#define PCMCIA -#include "ibmtr.c" - - -/*====================================================================*/ - -/* Parameters that can be set with 'insmod' */ - -/* MMIO base address */ -static u_long mmiobase = 0xce000; - -/* SRAM base address */ -static u_long srambase = 0xd0000; - -/* SRAM size 8,16,32,64 */ -static u_long sramsize = 64; - -/* Ringspeed 4,16 */ -static int ringspeed = 16; - -module_param(mmiobase, ulong, 0); -module_param(srambase, ulong, 0); -module_param(sramsize, ulong, 0); -module_param(ringspeed, int, 0); -MODULE_LICENSE("GPL"); - -/*====================================================================*/ - -static int ibmtr_config(struct pcmcia_device *link); -static void ibmtr_hw_setup(struct net_device *dev, u_int mmiobase); -static void ibmtr_release(struct pcmcia_device *link); -static void ibmtr_detach(struct pcmcia_device *p_dev); - -/*====================================================================*/ - -typedef struct ibmtr_dev_t { - struct pcmcia_device *p_dev; - struct net_device *dev; - struct tok_info *ti; -} ibmtr_dev_t; - -static irqreturn_t ibmtr_interrupt(int irq, void *dev_id) { - ibmtr_dev_t *info = dev_id; - struct net_device *dev = info->dev; - return tok_interrupt(irq, dev); -}; - -static int __devinit ibmtr_attach(struct pcmcia_device *link) -{ - ibmtr_dev_t *info; - struct net_device *dev; - - dev_dbg(&link->dev, "ibmtr_attach()\n"); - - /* Create new token-ring device */ - info = kzalloc(sizeof(*info), GFP_KERNEL); - if (!info) return -ENOMEM; - dev = alloc_trdev(sizeof(struct tok_info)); - if (!dev) { - kfree(info); - return -ENOMEM; - } - - info->p_dev = link; - link->priv = info; - info->ti = netdev_priv(dev); - - link->resource[0]->flags |= IO_DATA_PATH_WIDTH_8; - link->resource[0]->end = 4; - link->config_flags |= CONF_ENABLE_IRQ; - link->config_regs = PRESENT_OPTION; - - info->dev = dev; - - return ibmtr_config(link); -} /* ibmtr_attach */ - -static void ibmtr_detach(struct pcmcia_device *link) -{ - struct ibmtr_dev_t *info = link->priv; - struct net_device *dev = info->dev; - struct tok_info *ti = netdev_priv(dev); - - dev_dbg(&link->dev, "ibmtr_detach\n"); - - /* - * When the card removal interrupt hits tok_interrupt(), - * bail out early, so we don't crash the machine - */ - ti->sram_phys |= 1; - - unregister_netdev(dev); - - del_timer_sync(&(ti->tr_timer)); - - ibmtr_release(link); - - free_netdev(dev); - kfree(info); -} /* ibmtr_detach */ - -static int __devinit ibmtr_config(struct pcmcia_device *link) -{ - ibmtr_dev_t *info = link->priv; - struct net_device *dev = info->dev; - struct tok_info *ti = netdev_priv(dev); - int i, ret; - - dev_dbg(&link->dev, "ibmtr_config\n"); - - link->io_lines = 16; - link->config_index = 0x61; - - /* Determine if this is PRIMARY or ALTERNATE. */ - - /* Try PRIMARY card at 0xA20-0xA23 */ - link->resource[0]->start = 0xA20; - i = pcmcia_request_io(link); - if (i != 0) { - /* Couldn't get 0xA20-0xA23.

Bug was there all along but was - * silently ignored until the error checking code - * went into version 1.0.0 - * 06/04/02 - Add correct start up sequence for the cardbus adapters. - * Required for strict compliance with pci power mgmt specs. - * To Do: - * - * Wake on lan - * - * If Problems do Occur - * Most problems can be rectified by either closing and opening the interface - * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult - * if compiled into the kernel). - */ - -/* Change OLYMPIC_DEBUG to 1 to get verbose, and I mean really verbose, messages */ - -#define OLYMPIC_DEBUG 0 - - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#include -#include - -#include - -#include "olympic.h" - -/* I've got to put some intelligence into the version number so that Peter and I know - * which version of the code somebody has got. - * Version Number = a.b.c.d where a.b.c is the level of code and d is the latest author. - * So 0.0.1.pds = Peter, 0.0.1.mlp = Mike - * - * Official releases will only have an a.b.c version number format. - */ - -static char version[] = -"Olympic.c v1.0.5 6/04/02 - Peter De Schrijver & Mike Phillips" ; - -static char *open_maj_error[] = {"No error", "Lobe Media Test", "Physical Insertion", - "Address Verification", "Neighbor Notification (Ring Poll)", - "Request Parameters","FDX Registration Request", - "FDX Duplicate Address Check", "Station registration Query Wait", - "Unknown stage"}; - -static char *open_min_error[] = {"No error", "Function Failure", "Signal Lost", "Wire Fault", - "Ring Speed Mismatch", "Timeout","Ring Failure","Ring Beaconing", - "Duplicate Node Address","Request Parameters","Remove Received", - "Reserved", "Reserved", "No Monitor Detected for RPL", - "Monitor Contention failer for RPL", "FDX Protocol Error"}; - -/* Module parameters */ - -MODULE_AUTHOR("Mike Phillips ") ; -MODULE_DESCRIPTION("Olympic PCI/Cardbus Chipset Driver") ; - -/* Ring Speed 0,4,16,100 - * 0 = Autosense - * 4,16 = Selected speed only, no autosense - * This allows the card to be the first on the ring - * and become the active monitor. - * 100 = Nothing at present, 100mbps is autodetected - * if FDX is turned on.
