Either someone wasn't - too used to dem bit en bites, or they were trying to obfuscate the - programming interface. - - There is an additional complication when setting the window on the packet - buffer. You must first do a read into the packet buffer region with the - low 8 address bits the address setting the page for the start of the packet - buffer window, and then do the above operation. See mem_on() for details. - - One bug on the chip is that even a hard reset won't disable the memory - window, usually resulting in a hung machine if mem_off() isn't called. - If this happens, you must power down the machine for about 30 seconds. -*/ - -static const char version[] = - "e2100.c:v1.01 7/21/94 Donald Becker (becker@cesdis.gsfc.nasa.gov)\n"; - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/errno.h> -#include <linux/string.h> -#include <linux/ioport.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/init.h> -#include <linux/interrupt.h> -#include <linux/delay.h> - -#include <asm/io.h> - -#include "8390.h" - -#define DRV_NAME "e2100" - -static int e21_probe_list[] = {0x300, 0x280, 0x380, 0x220, 0}; - -/* Offsets from the base_addr. - Read from the ASIC register, and the low three bits of the next outb() - address is used to set the corresponding register. */ -#define E21_NIC_OFFSET 0 /* Offset to the 8390 NIC. */ -#define E21_ASIC 0x10 -#define E21_MEM_ENABLE 0x10 -#define E21_MEM_ON 0x05 /* Enable memory in 16 bit mode. */ -#define E21_MEM_ON_8 0x07 /* Enable memory in 8 bit mode. */ -#define E21_MEM_BASE 0x11 -#define E21_IRQ_LOW 0x12 /* The low three bits of the IRQ number. */ -#define E21_IRQ_HIGH 0x14 /* The high IRQ bit and media select ... */ -#define E21_MEDIA 0x14 /* (alias). */ -#define E21_ALT_IFPORT 0x02 /* Set to use the other (BNC,AUI) port. */ -#define E21_BIG_MEM 0x04 /* Use a bigger (64K) buffer (we don't) */ -#define E21_SAPROM 0x10 /* Offset to station address data. */ -#define E21_IO_EXTENT 0x20 - -static inline void mem_on(short port, volatile char __iomem *mem_base, - unsigned char start_page ) -{ - /* This is a little weird: set the shared memory window by doing a - read.

It has a shared memory mode of - operation that makes it similar to the ISA version of the card. - The main difference is that the EISA card has 32KB of RAM, but - only an 8KB window into that memory. The EISA card also can be - set for a bus-mastering mode of operation via the ECU, but that - is not (and probably will never be) supported by this driver. - The ECU should be run to enable shared memory and to disable the - bus-mastering feature for use with linux. - - By programming the 8390 to use only 8KB RAM, the modifications - to the ISA driver can be limited to the probe and initialization - code. This allows easy integration of EISA support into the ISA - driver. However, the driver development kit from SMC provided the - register information for sliding the 8KB window, and hence the 8390 - is programmed to use the full 32KB RAM. - - Unfortunately this required code changes outside the probe/init - routines, and thus we decided to separate the EISA driver from - the ISA one. In this way, ISA users don't end up with a larger - driver due to the EISA code, and EISA users don't end up with a - larger driver due to the ISA EtherEZ PIO code. The driver is - similar to the 3c503/16 driver, in that the window must be set - back to the 1st 8KB of space for access to the two 8390 Tx slots. - - In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to - be a limiting factor, since the EISA bus could get packets off - the card fast enough, but having the use of lots of RAM as Rx - space is extra insurance if interrupt latencies become excessive. - -*/ - -static const char *version = "smc-ultra32.c: 06/97 v1.00\n"; - - -#include <linux/module.h> -#include <linux/eisa.h> -#include <linux/kernel.h> -#include <linux/errno.h> -#include <linux/string.h> -#include <linux/init.h> -#include <linux/interrupt.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> - -#include <asm/io.h> - -#include "8390.h" - -#define DRV_NAME "smc-ultra32" - -static int ultra32_probe1(struct net_device *dev, int ioaddr); -static int ultra32_open(struct net_device *dev); -static void ultra32_reset_8390(struct net_device *dev); -static void ultra32_get_8390_hdr(struct net_device *dev, struct e8390_pkt_hdr *hdr, - int ring_page); -static void ultra32_block_input(struct net_device *dev, int count, - struct sk_buff *skb, int ring_offset); -static void ultra32_block_output(struct net_device *dev, int count, - const unsigned char *buf, - const int start_page); -static int ultra32_close(struct net_device *dev); - -#define ULTRA32_CMDREG 0 /* Offset to ASIC command register. */ -#define ULTRA32_RESET 0x80 /* Board reset, in ULTRA32_CMDREG. */ -#define ULTRA32_MEMENB 0x40 /* Enable the shared memory. */ -#define ULTRA32_NIC_OFFSET 16 /* NIC register offset from the base_addr. */ -#define ULTRA32_IO_EXTENT 32 -#define EN0_ERWCNT 0x08 /* Early receive warning count. */ - -/* - * Defines that apply only to the Ultra32 EISA card.
