<para>
|
||||
This device driver is designed for the DECchip "Tulip", Digital's
|
||||
single-chip ethernet controllers for PCI (now owned by Intel).
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.

||||

<chapter id="board-settings">
|
||||
<title>Board-specific Settings</title>
|
||||
|
||||
<para>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.

|
||||
<sect1><title>Ring buffers</title>
|
||||
|
||||
<para>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.
|
||||

|

|
||||
<sect1><title>Synchronization</title>
|
||||
<para>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.

<para>
|

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?
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.
|
||||
</para>
|
||||
|
||||
<para>
|
||||
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.

the via82cxxx_audio module itself.

Two /proc pseudo-files provide diagnostic information. This is generally

not useful to most users. Power users can disable CONFIG_SOUND_VIA82CXXX_PROCFS,

and remove the /proc support code. Once
|
||||
version 2.0.0 is released, the /proc support code will be disabled by
|

default. Available /proc pseudo-files:

The Via audio chip apparently provides a second PCM scatter-gather
|
||||
DMA channel just for FM data, but does not have a full hardware MIDI
|
||||
processor. I haven't put much thought towards a solution here, but it
|
||||
might involve using SoftOSS midi wave table, or simply disabling MIDI
|
||||
support altogether and using the FM PCM channel as a second (input? output?)
