SPDX-License-Identifier: GPL-2.0 - -============================================================================= -Linux and the 3Com EtherLink III Series Ethercards (driver v1.18c and higher) -============================================================================= - -This file contains the instructions and caveats for v1.18c and higher versions -of the 3c509 driver. You should not use the driver without reading this file. - -release 1.0 - -28 February 2002 - -Current maintainer (corrections to): - David Ruggiero - -Introduction -============ - -The following are notes and information on using the 3Com EtherLink III series -ethercards in Linux. These cards are commonly known by the most widely-used -card's 3Com model number, 3c509. They are all 10mb/s ISA-bus cards and shouldn't -be (but sometimes are) confused with the similarly-numbered PCI-bus "3c905" -(aka "Vortex" or "Boomerang") series. Kernel support for the 3c509 family is -provided by the module 3c509.c, which has code to support all of the following -models: - - - 3c509 (original ISA card) - - 3c509B (later revision of the ISA card; supports full-duplex) - - 3c589 (PCMCIA) - - 3c589B (later revision of the 3c589; supports full-duplex) - - 3c579 (EISA) - -Large portions of this documentation were heavily borrowed from the guide -written the original author of the 3c509 driver, Donald Becker. The master -copy of that document, which contains notes on older versions of the driver, -currently resides on Scyld web server: http://www.scyld.com/. - - -Special Driver Features -======================= - -Overriding card settings - -The driver allows boot- or load-time overriding of the card's detected IOADDR, -IRQ, and transceiver settings, although this capability shouldn't generally be -needed except to enable full-duplex mode (see below). An example of the syntax -for LILO parameters for doing this:: - - ether=10,0x310,3,0x3c509,eth0 - -This configures the first found 3c509 card for IRQ 10, base I/O 0x310, and -transceiver type 3 (10base2). The flag "0x3c509" must be set to avoid conflicts -with other card types when overriding the I/O address. When the driver is -loaded as a module, only the IRQ may be overridden. For example, -setting two cards to IRQ10 and IRQ11 is done by using the irq module -option:: - - options 3c509 irq=10,11 - - -Full-duplex mode -================ - -The v1.18c driver added support for the 3c509B's full-duplex capabilities. -In order to enable and successfully use full-duplex mode, three conditions -must be met: - -(a) You must have a Etherlink III card model whose hardware supports full- -duplex operations. Currently, the only members of the 3c509 family that are -positively known to support full-duplex are the 3c509B (ISA bus) and 3c589B -(PCMCIA) cards. Cards without the "B" model designation do *not* support -full-duplex mode; these include the original 3c509 (no "B"), the original -3c589, the 3c529 (MCA bus), and the 3c579 (EISA bus). - -(b) You must be using your card's 10baseT transceiver (i.e., the RJ-45 -connector), not its AUI (thick-net) or 10base2 (thin-net/coax) interfaces. -AUI and 10base2 network cabling is physically incapable of full-duplex -operation. - -(c) Most importantly, your 3c509B must be connected to a link partner that is -itself full-duplex capable. This is almost certainly one of two things: a full- -duplex-capable Ethernet switch (*not* a hub), or a full-duplex-capable NIC on -another system that's connected directly to the 3c509B via a crossover cable. - -Full-duplex mode can be enabled using 'ethtool'. - -.. warning:: - - Extremely important caution concerning full-duplex mode - - Understand that the 3c509B's hardware's full-duplex support is much more - limited than that provide by more modern network interface cards. Although - at the physical layer of the network it fully supports full-duplex operation, - the card was designed before the current Ethernet auto-negotiation (N-way) - spec was written. This means that the 3c509B family ***cannot and will not - auto-negotiate a full-duplex connection with its link partner under any - circumstances, no matter how it is initialized***. If the full-duplex mode - of the 3c509B is enabled, its link partner will very likely need to be - independently _forced_ into full-duplex mode as well; otherwise various nasty - failures will occur - at the very least, you'll see massive numbers of packet - collisions. This is one of very rare circumstances where disabling auto- - negotiation and forcing the duplex mode of a network interface card or switch - would ever be necessary or desirable. - - -Available Transceiver Types -=========================== - -For versions of the driver v1.18c and above, the available transceiver types are: - -== ========================================================================= -0 transceiver type from EEPROM config (normally 10baseT); force half-duplex -1 AUI (thick-net / DB15 connector) -2 (undefined) -3 10base2 (thin-net == coax / BNC connector) -4 10baseT (RJ-45 connector); force half-duplex mode -8 transceiver type and duplex mode taken from card's EEPROM config settings -12 10baseT (RJ-45 connector); force full-duplex mode -== ========================================================================= - -Prior to driver version 1.18c, only transceiver codes 0-4 were supported. Note -that the new transceiver codes 8 and 12 are the *only* ones that will enable -full-duplex mode, no matter what the card's detected EEPROM settings might be. -This insured that merely upgrading the driver from an earlier version would -never automatically enable full-duplex mode in an existing installation; -it must always be explicitly enabled via one of these code in order to be -activated. - -The transceiver type can be changed using 'ethtool'. - - -Interpretation of error messages and common problems ----------------------------------------------------- - -Error Messages -^^^^^^^^^^^^^^ - -eth0: Infinite loop in interrupt, status 2011. -These are "mostly harmless" message indicating that the driver had too much -work during that interrupt cycle. With a status of 0x2011 you are receiving -packets faster than they can be removed from the card. This should be rare -or impossible in normal operation. Possible causes of this error report are: - - - a "green" mode enabled that slows the processor down when there is no - keyboard activity. - - - some other device or device driver hogging the bus or disabling interrupts. - Check /proc/interrupts for excessive interrupt counts. The timer tick - interrupt should always be incrementing faster than the others. - -No received packets -^^^^^^^^^^^^^^^^^^^ - -If a 3c509, 3c562 or 3c589 can successfully transmit packets, but never -receives packets (as reported by /proc/net/dev or 'ifconfig') you likely -have an interrupt line problem. Check /proc/interrupts to verify that the -card is actually generating interrupts. If the interrupt count is not -increasing you likely have a physical conflict with two devices trying to -use the same ISA IRQ line. The common conflict is with a sound card on IRQ10 -or IRQ5, and the easiest solution is to move the 3c509 to a different -interrupt line. If the device is receiving packets but 'ping' doesn't work, -you have a routing problem. - -Tx Carrier Errors Reported in /proc/net/dev -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - - -If an EtherLink III appears to transmit packets, but the "Tx carrier errors" -field in /proc/net/dev increments as quickly as the Tx packet count, you -likely have an unterminated network or the incorrect media transceiver selected. - -3c509B card is not detected on machines with an ISA PnP BIOS. -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -While the updated driver works with most PnP BIOS programs, it does not work -with all. This can be fixed by disabling PnP support using the 3Com-supplied -setup program. - -3c509 card is not detected on overclocked machines -^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ - -Increase the delay time in id_read_eeprom() from the current value, 500, -to an absurdly high value, such as 5000. - - -Decoding Status and Error Messages ----------------------------------- - - -The bits in the main status register are: - -===== ====================================== -value description -===== ====================================== -0x01 Interrupt latch -0x02 Tx overrun, or Rx underrun -0x04 Tx complete -0x08 Tx FIFO room available -0x10 A complete Rx packet has arrived -0x20 A Rx packet has started to arrive -0x40 The driver has requested an interrupt -0x80 Statistics counter nearly full -===== ====================================== - -The bits in the transmit (Tx) status word are: - -===== ============================================ -value description -===== ============================================ -0x02 Out-of-window collision. -0x04 Status stack overflow (normally impossible). -0x08 16 collisions. -0x10 Tx underrun (not enough PCI bus bandwidth). -0x20 Tx jabber. -0x40 Tx interrupt requested. -0x80 Status is valid (this should always be set). -===== ============================================ - - -When a transmit error occurs the driver produces a status message such as:: - - eth0: Transmit error, Tx status register 82 - -The two values typically seen here are: - -0x82 -^^^^ - -Out of window collision. This typically occurs when some other Ethernet -host is incorrectly set to full duplex on a half duplex network. - -0x88 -^^^^ - -16 collisions. This typically occurs when the network is exceptionally busy -or when another host doesn't correctly back off after a collision. If this -error is mixed with 0x82 errors it is the result of a host incorrectly set -to full duplex (see above). - -Both of these errors are the result of network problems that should be -corrected.

Board Compatibility - -This device driver is designed for the 3Com 3c515 ISA Fast EtherLink XL, -3Com's ISA bus adapter for Fast Ethernet. Due to the unique I/O port layout, -it's not practical to integrate this driver with the other EtherLink drivers. - -II. Board-specific settings - -The Corkscrew has an EEPROM for configuration, but no special settings are -needed for Linux. - -III. Driver operation - -The 3c515 series use an interface that's very similar to the 3c900 "Boomerang" -PCI cards, with the bus master interface extensively modified to work with -the ISA bus. - -The card is capable of full-bus-master transfers with separate -lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet, -DEC Tulip and Intel Speedo3. - -This driver uses a "RX_COPYBREAK" scheme rather than a fixed intermediate -receive buffer. This scheme allocates full-sized skbuffs as receive -buffers. The value RX_COPYBREAK is used as the copying breakpoint: it is -chosen to trade-off the memory wasted by passing the full-sized skbuff to -the queue layer for all frames vs. the copying cost of copying a frame to a -correctly-sized skbuff. - - -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 netif -layer. The other thread is the interrupt handler, which is single -threaded by the hardware and other software. - -IV. Notes - -Thanks to Terry Murphy of 3Com for providing documentation and a development -board. - -The names "Vortex", "Boomerang" and "Corkscrew" are the internal 3Com -project names. I use these names to eliminate confusion -- 3Com product -numbers and names are very similar and often confused. - -The new chips support both ethernet (1.5K) and FDDI (4.5K) frame sizes! -This driver only supports ethernet frames because of the recent MTU limit -of 1.5K, but the changes to support 4.5K are minimal. -*/ - -/* Operational definitions. - These are not used by other compilation units and thus are not - exported in a ".h" file. - - First the windows.

Board Compatibility - -This device driver is designed for the 3Com 3c574 PC card Fast Ethernet -Adapter. - -II. Board-specific settings - -None -- PC cards are autoconfigured. - -III. Driver operation - -The 3c574 uses a Boomerang-style interface, without the bus-master capability. -See the Boomerang driver and documentation for most details. - -IV. Notes and chip documentation. - -Two added registers are used to enhance PIO performance, RunnerRdCtrl and -RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the -count of word (16 bits) reads or writes the driver is about to do to the Rx -or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card -translation latency by buffering the I/O operations with an 8 word FIFO. -Note: No other chip accesses are permitted when this buffer is used. - -A second enhancement is that both attribute and common memory space -0x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster -with *some* PCcard bridges) may be used instead of I/O operations. -This is enabled by setting the 0x10 bit in the PCMCIA LAN COR. - -Some slow PC card bridges work better if they never see a WAIT signal. -This is configured by setting the 0x20 bit in the PCMCIA LAN COR. -Only do this after testing that it is reliable and improves performance. - -The upper five bits of RunnerRdCtrl are used to window into PCcard -configuration space registers. Window 0 is the regular Boomerang/Odie -register set, 1-5 are various PC card control registers, and 16-31 are -the (reversed!) CIS table. - -A final note: writing the InternalConfig register in window 3 with an -invalid ramWidth is Very Bad. - -V.

Board Compatibility - -This device driver is designed for the AMD 79C960, the "PCnet-ISA -single-chip ethernet controller for ISA". This chip is used in a wide -variety of boards from vendors such as Allied Telesis, HP, Kingston, -and Boca. This driver is also intended to work with older AMD 7990 -designs, such as the NE1500 and NE2100, and newer 79C961. For convenience, -I use the name LANCE to refer to all of the AMD chips, even though it properly -refers only to the original 7990. - -II. Board-specific settings - -The driver is designed to work the boards that use the faster -bus-master mode, rather than in shared memory mode. (Only older designs -have on-board buffer memory needed to support the slower shared memory mode.) - -Most ISA boards have jumpered settings for the I/O base, IRQ line, and DMA -channel. This driver probes the likely base addresses: -{0x300, 0x320, 0x340, 0x360}. -After the board is found it generates a DMA-timeout interrupt and uses -autoIRQ to find the IRQ line. The DMA channel can be set with the low bits -of the otherwise-unused dev->mem_start value (aka PARAM1). If unset it is -probed for by enabling each free DMA channel in turn and checking if -initialization succeeds. - -The HP-J2405A board is an exception: with this board it is easy to read the -EEPROM-set values for the base, IRQ, and DMA. (Of course you must already -_know_ the base address -- that field is for writing the EEPROM.) - -III. Driver operation - -IIIa. Ring buffers -The LANCE uses ring buffers of Tx and Rx descriptors. Each entry describes -the base and length of the data buffer, along with status bits. The length -of these buffers is set by LANCE_LOG_{RX,TX}_BUFFERS, which is log_2() of -the buffer length (rather than being directly the buffer length) for -implementation ease. The current values are 2 (Tx) and 4 (Rx), which leads to -ring sizes of 4 (Tx) and 16 (Rx). Increasing the number of ring entries -needlessly uses extra space and reduces the chance that an upper layer will -be able to reorder queued Tx packets based on priority. Decreasing the number -of entries makes it more difficult to achieve back-to-back packet transmission -and increases the chance that Rx ring will overflow. (Consider the worst case -of receiving back-to-back minimum-sized packets.) - -The LANCE has the capability to "chain" both Rx and Tx buffers, but this driver -statically allocates full-sized (slightly oversized -- PKT_BUF_SZ) buffers to -avoid the administrative overhead. For the Rx side this avoids dynamically -allocating full-sized buffers "just in case", at the expense of a -memory-to-memory data copy for each packet received. For most systems this -is a good tradeoff: the Rx buffer will always be in low memory, the copy -is inexpensive, and it primes the cache for later packet processing. For Tx -the buffers are only used when needed as low-memory bounce buffers. - -IIIB. 16M memory limitations. -For the ISA bus master mode all structures used directly by the LANCE, -the initialization block, Rx and Tx rings, and data buffers, must be -accessible from the ISA bus, i.e. in the lower 16M of real memory. -This is a problem for current Linux kernels on >16M machines. The network -devices are initialized after memory initialization, and the kernel doles out -memory from the top of memory downward. The current solution is to have a -special network initialization routine that's called before memory -initialization; this will eventually be generalized for all network devices. -As mentioned before, low-memory "bounce-buffers" are used when needed. - -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 'lp->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.)

It'd be better to shuffle - these skbs to a temp list and then actually re-Tx them after - restarting the chip, but I'm too lazy to do so right now. dplatt@3do.com -*/ - -static void -lance_purge_ring(struct net_device *dev) -{ - struct lance_private *lp = dev->ml_priv; - int i; - - /* Free all the skbuffs in the Rx and Tx queues. */ - for (i = 0; i < RX_RING_SIZE; i++) { - struct sk_buff *skb = lp->rx_skbuff[i]; - lp->rx_skbuff[i] = NULL; - lp->rx_ring[i].base = 0; /* Not owned by LANCE chip. */ - if (skb) - dev_kfree_skb_any(skb); - } - for (i = 0; i < TX_RING_SIZE; i++) { - if (lp->tx_skbuff[i]) { - dev_kfree_skb_any(lp->tx_skbuff[i]); - lp->tx_skbuff[i] = NULL; - } - } -} - - -/* Initialize the LANCE Rx and Tx rings. */ -static void -lance_init_ring(struct net_device *dev, gfp_t gfp) -{ - struct lance_private *lp = dev->ml_priv; - int i; - - lp->cur_rx = lp->cur_tx = 0; - lp->dirty_rx = lp->dirty_tx = 0; - - for (i = 0; i < RX_RING_SIZE; i++) { - struct sk_buff *skb; - void *rx_buff; - - skb = alloc_skb(PKT_BUF_SZ, GFP_DMA | gfp); - lp->rx_skbuff[i] = skb; - if (skb) - rx_buff = skb->data; - else - rx_buff = kmalloc(PKT_BUF_SZ, GFP_DMA | gfp); - if (!rx_buff) - lp->rx_ring[i].base = 0; - else - lp->rx_ring[i].base = (u32)isa_virt_to_bus(rx_buff) | 0x80000000; - lp->rx_ring[i].buf_length = -PKT_BUF_SZ; - } - /* The Tx buffer address is filled in as needed, but we do need to clear - the upper ownership bit. */ - for (i = 0; i < TX_RING_SIZE; i++) { - lp->tx_skbuff[i] = NULL; - lp->tx_ring[i].base = 0; - } - - lp->init_block.mode = 0x0000; - for (i = 0; i < 6; i++) - lp->init_block.phys_addr[i] = dev->dev_addr[i]; - lp->init_block.filter[0] = 0x00000000; - lp->init_block.filter[1] = 0x00000000; - lp->init_block.rx_ring = ((u32)isa_virt_to_bus(lp->rx_ring) & 0xffffff) | RX_RING_LEN_BITS; - lp->init_block.tx_ring = ((u32)isa_virt_to_bus(lp->tx_ring) & 0xffffff) | TX_RING_LEN_BITS; -} - -static void -lance_restart(struct net_device *dev, unsigned int csr0_bits, int must_reinit) -{ - struct lance_private *lp = dev->ml_priv; - - if (must_reinit || - (chip_table[lp->chip_version].flags & LANCE_MUST_REINIT_RING)) { - lance_purge_ring(dev); - lance_init_ring(dev, GFP_ATOMIC); - } - outw(0x0000, dev->base_addr + LANCE_ADDR); - outw(csr0_bits, dev->base_addr + LANCE_DATA); -} - - -static void lance_tx_timeout (struct net_device *dev, unsigned int txqueue) -{ - struct lance_private *lp = (struct lance_private *) dev->ml_priv; - int ioaddr = dev->base_addr; - - outw (0, ioaddr + LANCE_ADDR); - printk ("%s: transmit timed out, status %4.4x, resetting.\n", - dev->name, inw (ioaddr + LANCE_DATA)); - outw (0x0004, ioaddr + LANCE_DATA); - dev->stats.tx_errors++; -#ifndef final_version - if (lance_debug > 3) { - int i; - printk (" Ring data dump: dirty_tx %d cur_tx %d%s cur_rx %d.", - lp->dirty_tx, lp->cur_tx, netif_queue_stopped(dev) ?
