Instead of just patching the old code to make it - work, the PCMCIA code has been streamlined, updated and possibly - improved. - - This code now only contains code required for the Card Services. - All we do here is set the card up enough so that the real ibmtr.c - driver can find it and work with it properly. - - i.e. We set up the io port, irq, mmio memory and shared ram - memory. 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 <linux/kernel.h> -#include <linux/init.h> -#include <linux/ptrace.h> -#include <linux/slab.h> -#include <linux/string.h> -#include <linux/timer.h> -#include <linux/module.h> -#include <linux/netdevice.h> -#include <linux/trdevice.h> -#include <linux/ibmtr.h> - -#include <pcmcia/cistpl.h> -#include <pcmcia/ds.h> - -#include <asm/uaccess.h> -#include <asm/io.h> - -#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 <linux/module.h> -#include <linux/kernel.h> -#include <linux/errno.h> -#include <linux/timer.h> -#include <linux/in.h> -#include <linux/ioport.h> -#include <linux/seq_file.h> -#include <linux/string.h> -#include <linux/proc_fs.h> -#include <linux/ptrace.h> -#include <linux/skbuff.h> -#include <linux/interrupt.h> -#include <linux/delay.h> -#include <linux/netdevice.h> -#include <linux/trdevice.h> -#include <linux/stddef.h> -#include <linux/init.h> -#include <linux/pci.h> -#include <linux/spinlock.h> -#include <linux/bitops.h> -#include <linux/jiffies.h> - -#include <net/checksum.h> -#include <net/net_namespace.h> - -#include <asm/io.h> - -#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 <mikep@linuxtr.net>") ; -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.

* 31-May-98 JS Hacked in PCI support - * 16-Jun-98 JS Modulized for multiple cards with one driver - * Sep-99 AF Renamed to tms380tr (supports more than SK's) - * 23-Sep-99 AF Added Compaq and Thomas-Conrad PCI support - * Fixed a bug causing double copies on PCI - * Fixed for new multicast stuff (2.2/2.3) - * 25-Sep-99 AF Uped TPL_NUM from 3 to 9 - * Removed extraneous 'No free TPL' - * 22-Dec-99 AF Added Madge PCI Mk2 support and generalized - * parts of the initilization procedure. - * 30-Dec-99 AF Turned tms380tr into a library ala 8390. - * Madge support is provided in the abyss module - * Generic PCI support is in the tmspci module. - * 30-Nov-00 JF Updated PCI code to support IO MMU via - * pci_map_static(). Alpha uses this MMU for ISA - * as well. - * 14-Jan-01 JF Fix DMA on ifdown/ifup sequences. Some - * cleanup. - * 13-Jan-02 JF Add spinlock to fix race condition. - * 09-Nov-02 JF Fixed printks to not SPAM the console during - * normal operation. - * 30-Dec-02 JF Removed incorrect __init from - * tms380tr_init_card. - * 22-Jul-05 JF Converted to dma-mapping. - * - * To do: - * 1. Multi/Broadcast packet handling (this may have fixed itself) - * 2. Write a sktrisa module that includes the old ISA support (done) - * 3. Allow modules to load their own microcode - * 4. Speed up the BUD process -- freezing the kernel for 3+sec is - * quite unacceptable. - * 5. Still a few remaining stalls when the cable is unplugged. - */ - -#ifdef MODULE -static const char version[] = "tms380tr.c: v1.10 30/12/2002 by Christoph Goos, Adam Fritzler\n"; -#endif - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/types.h> -#include <linux/fcntl.h> -#include <linux/interrupt.h> -#include <linux/ptrace.h> -#include <linux/ioport.h> -#include <linux/in.h> -#include <linux/string.h> -#include <linux/time.h> -#include <linux/errno.h> -#include <linux/init.h> -#include <linux/dma-mapping.h> -#include <linux/delay.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/skbuff.h> -#include <linux/trdevice.h> -#include <linux/firmware.h> -#include <linux/bitops.h> - -#include <asm/io.h> -#include <asm/dma.h> -#include <asm/irq.h> -#include <asm/uaccess.h> - -#include "tms380tr.h" /* Our Stuff */ - -/* Use 0 for production, 1 for verification, 2 for debug, and - * 3 for very verbose debug. - */ -#ifndef TMS380TR_DEBUG -#define TMS380TR_DEBUG 0 -#endif -static unsigned int tms380tr_debug = TMS380TR_DEBUG;
