thorpej a7dc1c1b01 Some whitespace cleanup. 2001-07-23 17:08:18 +00:00
jdolecek 031c6d8c24 Add MCA ep(4) attachment, for 3Com 3c529-type cards. Tested with 3c529-TP,
provided to me by David Brownlee (thanks!).

Performance of this card is quite poor on my PS/2 with 386DX, like 100KB/s
at best, but as low as 5KB/s when transferring bigger files due to
packet overruns. It would be good to revisit this later, probably by
teaching the ic code to use RX Early.

jdolecek 4ffa6a80d6 convert to use ether_ioctl()
fix bunch of typos

jhawk 1e59d99d28 For all network drivers that call ether_ifattach(), and also
have _detach() functions:
  Ensure that softc keeps state about whether the attach succeeded,
  and make the detach function return immediately if the attach did
  not complete.

thorpej fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

enami c7573d517e - Bail out from attach stage if failed to enable card, number of iospace
or memspace is unexpected, failed to map iospace or failed to configure
the controller properly.
- Disestablish an interrupt handler if failed to enable card.

augustss e4c766e299 Make sure to untimeout() things on detach. 2000-02-02 08:57:51 +00:00
augustss ea45df4d30 Make sure to get rid of shutdown hook and ttach media on detach. 2000-02-02 08:00:21 +00:00
thorpej 1d0f24882d Now that the *_activate() functions don't do things which are attachment
specific, move them into the chipset drivers.

thorpej dd6750820c Expose the "enable" and "disable" functions so that the front-ends can
access them.

fvdl 7b10c3e7e4 Add the 'ex' driver, a DMA driver for 3Com 90x and 90xB cards. Rename
constants from EP_ to ELINK_ since they're now used in the ex driver as well.

thorpej 6bfd748b46 First-crack at RoadRunner (3c574-TX 10/100Mbps PCMCIA). Doens't yet use
any of the RoadRunner speed hacks.

thorpej 31a3d86b80 Define the Corkscrew chipset - used by the 3c515 ISA 10/100mbps cards. 1998-08-15 16:15:40 +00:00
thorpej ccf620bfab Define the 3Com "RoadRunner" chipset; like the Boomerang, but for PCMCIA.
No DMA is wired up, it has a shared memory interface, and a FIFO buffer
which can be used to speed up PIO transfers.  (The latter two are
PCMCIA-specific speed hacks to deal hide the performance lossage from
using a PCMCIA->PCI bridge internally.)

thorpej b170caf730 Completely rewrite media selection. Add support for the MII/PHY on
the 3Com 3c905-TX and 3c905-T4.  Fix handling of the MII on the
3c595-MII and 3c597-MII (can't talk to the PHYs on these cards; just
use "manual" for the external MII port).

Fixes kern/4782 (Chris Demetriou).

thorpej 10708da893 Pull down from marc-pcmcia branch:
Minor tweaks to deal with PCMCIA differences, and support for power
management.

jonathan c1f72bba37 Add ifmedia hooks: include <ifmedia.h> and add sc_media to softc. 1997-03-30 22:47:05 +00:00
is 07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

jonathan c7cec27edf Move if_ep media-sense code from front ends to inside back end,
to prepare for if_media, and to support EISA 3c59x cards:

  * change epconfig() to take a short that encodes the chipset
    type (3c509, or Demon/Vortex/Boomerang).
  * add  distinct 3c509 and Demon/Vortex/Boomerang media-sense
    functions to back end.
  * Add EISA match/attach support for the 3c592 and 3c597
    (Demon) cards as well as the 3c509-comatibl EISA 3c509/3c579.

  * Assume that ISA and ISA PnP cards are 3c509-style, until
    proof to the contrary (e.g. large packet support).

Tested on 3c595, 3c590, and 3c509b. Not tested on 3c515 or Demon.

jonathan 259ce9f178 * make sure 100mbit media-present bits don't collied with 3c509
CONFIG_CNTRL bits by making the "conn" argument to epconfig()
   a u_int, not a u_int16_t, and by defining 100mbit media
   bits in the upper 16 bits.

A redesigned interface that fixes this properly is in the pipeline.
1996-12-30 19:18:28 +00:00
jonathan 48f7828104 * Expand softc sc_connectors field to 16 bits.
For now, we really only need 8 bits of media type.

* Add bogus definitions for 100mbit transcievers, to be set in the
  "conn" argument to ep_config(). Should  really  use the same bits
  as in EP_W0_CONFIG_CTRL bits, but I don't know what bits the 3c515
  &c use for 100mbit media.

* Define bitflags for 100Mbit transceiver options in ep_connectors.

* Add definitions of powerup/powerdown commands. for interfaces with
  power management. Should send a powerup after APM resume?

* Add definition of fragment-busmaster (vortex) START_DMA command.

* Add definition  of PCI configuration-space media-present bits.
  (really just EP_W3_RESET_OPTIONS remapped into pci config space.)

* Add comments describing what the #define's above are used for.

jonathan 16d760f318 Fix for hanging 3com ``large packet'' (100Mbit) Etherlink-III devices:
* Add a slot in the softc, ep_pktlenshift, to indicate that
    a board implements ``large packets'' (FDDI-sized frames) and
    therefore implicitly shifts the argument to packet-length commands
    by two bits to fit a 13-bit length in  an 11-bit command argument field.

 *  Change  the reset of station-mask filterto be independent of bus-type
    (e.g.,. for 3c515)

 * Replace  the "2044" constant used to disable TX threshold interrupts
   on 3c509-generation cards with a #define. Use 2047 instead,
   since that works on the large-packet cards (Vortex, Demon, Boomerang)
   and 2044 doesn't.

 *  Add code to  epconfing to probe for large-packet support,
    set the softc appropriately, and  shift packet sizes in commands
    by ep_pktlenshift to compensate  for the implicit shift.

 *  Tweak the epconfig() code to avoid hanging on startup.
    Set the Tx threshold to interrupt when there's space for
    a maximal-sized ether frame, then  do epinit() then epstop(),
    instead of just the Tx and Rx reset. Required on at least a 3c595.

Tested on  a 3c595, but not on 3c509-generation hardware.

thorpej 16c4c5af26 New bus.h implementation/interface:
- No more distinction between i/o-mapped and memory-mapped
	  devices.  It's all "bus space" now, and space tags
	  differentiate the space with finer grain than the
	  bus chipset tag.
	- Add memory barrier methods.
	- Implement space alloc/free methods.
	- Implement region read/write methods (like memcpy to/from
	  bus space).
This interface provides a better abstraction for dealing with
machine-independent chipset drivers.

thorpej 5dc3777c41 Be more careful with types, and pull in <machine/intr.h> 1996-05-14 22:22:05 +00:00
thorpej f004654691 Update Herb's e-mail address; beer.org feels a lot more friendly. 1996-05-10 05:27:53 +00:00
christos a16dd8b648 Move epstop prototype to the header file. 1996-05-03 19:08:47 +00:00
thorpej 0b637e93a8 Convert the Etherlink III (ep) driver to use <machine/bus.h>. 1996-04-30 22:29:56 +00:00
thorpej aff40e2a72 Break up the ep driver into isa, eisa, and pci front-ends and a
bus-independent core driver.  Tested on all three bus types, including
an isa 3c509 masquerading as an eisa device (use ep* at eisa? slot ? in
your kernel config file to catch this one).
XXX Driver still needs to be converted to <machine/bus.h>
