20 Theory of Operation
21
22I. Board Compatibility
23
24This device driver is designed for the 3Com 3c574 PC card Fast Ethernet
25Adapter.
26
27II. Board-specific settings
28
29None -- PC cards are autoconfigured.
30
31III. Driver operation
32
33The 3c574 uses a Boomerang-style interface, without the bus-master capability.
34See the Boomerang driver and documentation for most details.
35
36IV. Notes and chip documentation.
37
38Two added registers are used to enhance PIO performance, RunnerRdCtrl and
39RunnerWrCtrl. These are 11 bit down-counters that are preloaded with the
40count of word (16 bits) reads or writes the driver is about to do to the Rx
41or Tx FIFO. The chip is then able to hide the internal-PCI-bus to PC-card
42translation latency by buffering the I/O operations with an 8 word FIFO.
43Note: No other chip accesses are permitted when this buffer is used.
44
45A second enhancement is that both attribute and common memory space
460x0800-0x0fff can translated to the PIO FIFO. Thus memory operations (faster
47with *some* PCcard bridges) may be used instead of I/O operations.
48This is enabled by setting the 0x10 bit in the PCMCIA LAN COR.
49
50Some slow PC card bridges work better if they never see a WAIT signal.
51This is configured by setting the 0x20 bit in the PCMCIA LAN COR.
52Only do this after testing that it is reliable and improves performance.
53
54The upper five bits of RunnerRdCtrl are used to window into PCcard
55configuration space registers. Window 0 is the regular Boomerang/Odie
56register set, 1-5 are various PC card control registers, and 16-31 are
57the (reversed!) CIS table.
58
59A final note: writing the InternalConfig register in window 3 with an
60invalid ramWidth is Very Bad.
