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. | |
