Modifications to support the EISA - version of the card by Paul Gortmaker and Leonard N. Zubkoff. - - This software may be used and distributed according to the terms - of the GNU General Public License, incorporated herein by reference. - -Theory of Operation: - - The SMC Ultra32C card uses the SMC 83c790 chip which is also - found on the ISA SMC Ultra cards. 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.
