| 132 | Theory of Operation |
| 133 | |
| 134 | I. Board Compatibility |
| 135 | |
| 136 | This device driver is designed for the 3Com FastEtherLink and FastEtherLink |
| 137 | XL, 3Com's PCI to 10/100baseT adapters. It also works with the 10Mbs |
| 138 | versions of the FastEtherLink cards. The supported product IDs are |
| 139 | 3c590, 3c592, 3c595, 3c597, 3c900, 3c905 |
| 140 | |
| 141 | The related ISA 3c515 is supported with a separate driver, 3c515.c, included |
| 142 | with the kernel source or available from |
| 143 | cesdis.gsfc.nasa.gov:/pub/linux/drivers/3c515.html |
| 144 | |
| 145 | II. Board-specific settings |
| 146 | |
| 147 | PCI bus devices are configured by the system at boot time, so no jumpers |
| 148 | need to be set on the board. The system BIOS should be set to assign the |
| 149 | PCI INTA signal to an otherwise unused system IRQ line. |
| 150 | |
| 151 | The EEPROM settings for media type and forced-full-duplex are observed. |
| 152 | The EEPROM media type should be left at the default "autoselect" unless using |
| 153 | 10base2 or AUI connections which cannot be reliably detected. |
| 154 | |
| 155 | III. Driver operation |
| 156 | |
| 157 | The 3c59x series use an interface that's very similar to the previous 3c5x9 |
| 158 | series. The primary interface is two programmed-I/O FIFOs, with an |
| 159 | alternate single-contiguous-region bus-master transfer (see next). |
| 160 | |
| 161 | The 3c900 "Boomerang" series uses a full-bus-master interface with separate |
| 162 | lists of transmit and receive descriptors, similar to the AMD LANCE/PCnet, |
| 163 | DEC Tulip and Intel Speedo3. The first chip version retains a compatible |
| 164 | programmed-I/O interface that has been removed in 'B' and subsequent board |
| 165 | revisions. |
| 166 | |
| 167 | One extension that is advertised in a very large font is that the adapters |
| 168 | are capable of being bus masters. On the Vortex chip this capability was |
| 169 | only for a single contiguous region making it far less useful than the full |
| 170 | bus master capability. There is a significant performance impact of taking |
| 171 | an extra interrupt or polling for the completion of each transfer, as well |
| 172 | as difficulty sharing the single transfer engine between the transmit and |
| 173 | receive threads. Using DMA transfers is a win only with large blocks or |
| 174 | with the flawed versions of the Intel Orion motherboard PCI controller. |
| 175 | |
| 176 | The Boomerang chip's full-bus-master interface is useful, and has the |
| 177 | currently-unused advantages over other similar chips that queued transmit |
| 178 | packets may be reordered and receive buffer groups are associated with a |
| 179 | single frame. |
| 180 | |
| 181 | With full-bus-master support, this driver uses a "RX_COPYBREAK" scheme. |
| 182 | Rather than a fixed intermediate receive buffer, this scheme allocates |
| 183 | full-sized skbuffs as receive buffers. The value RX_COPYBREAK is used as |
| 184 | the copying breakpoint: it is chosen to trade-off the memory wasted by |
| 185 | passing the full-sized skbuff to the queue layer for all frames vs. the |
| 186 | copying cost of copying a frame to a correctly-sized skbuff. |
| 187 | |
| 188 | IIIC. Synchronization |
| 189 | The driver runs as two independent, single-threaded flows of control. One |
| 190 | is the send-packet routine, which enforces single-threaded use by the |
| 191 | dev->tbusy flag. The other thread is the interrupt handler, which is single |
| 192 | threaded by the hardware and other software. |
| 193 | |
| 194 | IV. Notes |
| 195 | |
| 196 | Thanks to Cameron Spitzer and Terry Murphy of 3Com for providing development |
| 197 | 3c590, 3c595, and 3c900 boards. |
| 198 | The name "Vortex" is the internal 3Com project name for the PCI ASIC, and |
| 199 | the EISA version is called "Demon". According to Terry these names come |
| 200 | from rides at the local amusement park. |
| 201 | |
| 202 | The new chips support both ethernet (1.5K) and FDDI (4.5K) packet sizes! |
| 203 | This driver only supports ethernet packets because of the skbuff allocation |
| 204 | limit of 4K. |
