Board Compatibility - -This device driver is designed for the DECchip "Tulip", Digital's -single-chip ethernet controllers for PCI. Supported members of the family -are the 21040, 21041, 21140, 21140A, 21142, and 21143. Similar work-alike -chips from Lite-On, Macronics, ASIX, Compex and other listed below are also -supported. - -These chips are used on at least 140 unique PCI board designs. The great -number of chips and board designs supported is the reason for the -driver size and complexity. Almost of the increasing complexity is in the -board configuration and media selection code. There is very little -increasing in the operational critical path length. - -II. Board-specific settings - -PCI bus devices are configured by the system at boot time, so no jumpers -need to be set on the board. The system BIOS preferably should assign the -PCI INTA signal to an otherwise unused system IRQ line. - -Some boards have EEPROMs tables with default media entry. The factory default -is usually "autoselect". This should only be overridden when using -transceiver connections without link beat e.g. 10base2 or AUI, or (rarely!) -for forcing full-duplex when used with old link partners that do not do -autonegotiation. - -III. Driver operation - -IIIa. Ring buffers - -The Tulip can use either ring buffers or lists of Tx and Rx descriptors. -This driver uses statically allocated rings of Rx and Tx descriptors, set at -compile time by RX/TX_RING_SIZE. This version of the driver allocates skbuffs -for the Rx ring buffers at open() time and passes the skb->data field to the -Tulip as receive data buffers. When an incoming frame is less than -RX_COPYBREAK bytes long, a fresh skbuff is allocated and the frame is -copied to the new skbuff. When the incoming frame is larger, the skbuff is -passed directly up the protocol stack and replaced by a newly allocated -skbuff. - -The RX_COPYBREAK value is chosen to trade-off the memory wasted by -using a full-sized skbuff for small frames vs. the copying costs of larger -frames. For small frames the copying cost is negligible (esp. considering -that we are pre-loading the cache with immediately useful header -information). For large frames the copying cost is non-trivial, and the -larger copy might flush the cache of useful data. A subtle aspect of this -choice is that the Tulip only receives into longword aligned buffers, thus -the IP header at offset 14 isn't longword aligned for further processing. -Copied frames are put into the new skbuff at an offset of "+2", thus copying -has the beneficial effect of aligning the IP header and preloading the -cache. - -IIIC. Synchronization -The driver runs as two independent, single-threaded flows of control. One -is the send-packet routine, which enforces single-threaded use by the -dev->tbusy flag. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - -The send packet thread has partial control over the Tx ring and 'dev->tbusy' -flag. It sets the tbusy flag whenever it's queuing a Tx packet. If the next -queue slot is empty, it clears the tbusy flag when finished otherwise it sets -the 'tp->tx_full' flag. - -The interrupt handler has exclusive control over the Rx ring and records stats -from the Tx ring. (The Tx-done interrupt can't be selectively turned off, so -we can't avoid the interrupt overhead by having the Tx routine reap the Tx -stats.) After reaping the stats, it marks the queue entry as empty by setting -the 'base' to zero. Iff the 'tp->tx_full' flag is set, it clears both the -tx_full and tbusy flags. - -IV. Notes - -Thanks to Duke Kamstra of SMC for long ago providing an EtherPower board. -Greg LaPolla at Linksys provided PNIC and other Linksys boards. -Znyx provided a four-port card for testing. - -IVb.

Errata - -The old DEC databooks were light on details. -The 21040 databook claims that CSR13, CSR14, and CSR15 should each be the last -register of the set CSR12-15 written. Hmmm, now how is that possible? - -The DEC SROM format is very badly designed not precisely defined, leading to -part of the media selection junkheap below. Some boards do not have EEPROM -media tables and need to be patched up. Worse, other boards use the DEC -design kit media table when it isn't correct for their board. - -We cannot use MII interrupts because there is no defined GPIO pin to attach -them. The MII transceiver status is polled using an kernel timer. - -*/ - -static const char version[] = "Linux Tulip driver version 0.9.2 (Feb 15, 2000)\n"; - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/sched.h> -#include <linux/string.h> -#include <linux/timer.h> -#include <linux/ioport.h> -#include <linux/malloc.h> -#include <linux/interrupt.h> -#include <linux/pci.h> -#include <linux/netdevice.h> -#include <linux/etherdevice.h> -#include <linux/skbuff.h> -#include <linux/init.h> -#include <asm/processor.h> /* Processor type for cache alignment. */ -#include <asm/bitops.h> -#include <asm/io.h> -#include <asm/unaligned.h> -#include <asm/delay.h> - - -/* A few user-configurable values. */ - -/* Maximum events (Rx packets, etc.) to handle at each interrupt. */ -static int max_interrupt_work = 25; - -#define MAX_UNITS 8 -/* Used to pass the full-duplex flag, etc. */ -static int full_duplex[MAX_UNITS] = {0, }; -static int options[MAX_UNITS] = {0, }; -static int mtu[MAX_UNITS] = {0, }; /* Jumbo MTU for interfaces. */ - -/* The possible media types that can be set in options[] are: */ -static const char * const medianame[] = { - "10baseT", "10base2", "AUI", "100baseTx", - "10baseT-FD", "100baseTx-FD", "100baseT4", "100baseFx", - "100baseFx-FD", "MII 10baseT", "MII 10baseT-FD", "MII", - "10baseT(forced)", "MII 100baseTx", "MII 100baseTx-FD", "MII 100baseT4", -}; - -/* Set if the PCI BIOS detects the chips on a multiport board backwards. */ -#ifdef REVERSE_PROBE_ORDER -static int reverse_probe = 1; -#else -static int reverse_probe = 0; -#endif - -/* Keep the ring sizes a power of two for efficiency. - Making the Tx ring too large decreases the effectiveness of channel - bonding and packet priority. - There are no ill effects from too-large receive rings. */ -#define TX_RING_SIZE 16 -#define RX_RING_SIZE 32 - -/* Set the copy breakpoint for the copy-only-tiny-buffer Rx structure. */ -#ifdef __alpha__ -static int rx_copybreak = 1518; -#else -static int rx_copybreak = 100; -#endif - -/* - Set the bus performance register. - Typical: Set 16 longword cache alignment, no burst limit. - Cache alignment bits 15:14 Burst length 13:8 - 0000 No alignment 0x00000000 unlimited 0800 8 longwords - 4000 8 longwords 0100 1 longword 1000 16 longwords - 8000 16 longwords 0200 2 longwords 2000 32 longwords - C000 32 longwords 0400 4 longwords - Warning: many older 486 systems are broken and require setting 0x00A04800 - 8 longword cache alignment, 8 longword burst. - ToDo: Non-Intel setting could be better. -*/ - -#if defined(__alpha__) -static int csr0 = 0x01A00000 | 0xE000; -#elif defined(__i386__) || defined(__powerpc__) || defined(__sparc__) -static int csr0 = 0x01A00000 | 0x8000; -#else -#warning Processor architecture undefined!
