jonathan fac2cd30a0 Set TX-available threshhold in epinit() just before enabling interrupts,
so TX_AVAIL intrs are enabled for root-on-NFS kernels.
Tested (and required) on 3c595TX with root-on-NFS kernel booted from floppy.

mycroft 103c7d360d Oops; forgot to GC the last mbuf allocated when out of clusters. 1997-04-28 17:03:58 +00:00
jonathan dbf4f7b71f * Tidy PHY [sic] selection code in epsetmedia().
* epinit() had both explicit xcvr selection for 3c589 and a call
  to epsetmedia().  The first is redundant; delete it, and EP_COAX_DEFAULT.

* Update comments to reflect 3c589 and 3c509B fixes.  Fix typos.

veego a2e1f15ba7 - Replace the check for EP_BUS_PCMCIA in epsetmedia with a check for
EP_CHIPSET_3C509 and change it a bit so it works now with the 3c509
  and still works with the 3c589.

mycroft 581399fc4c If we fail to allocate a cluster to hold a large packet, simply
drop it rather than using a chain of tiny mbufs.

jonathan f11d74c508 Remove IFF_LINK[01] "connector" support.
Add if_media support.   Still missing a software autosense FSM.

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 4fdff0ed65 * Add ep_complete_cmd() function, to issue commands that perform a reset
(RX_RESET, TX_RESET, GLOBAL_RESET).
  Commands issued while a reset is in progress may be dropped. The driver
  must wait until resets are complete; ep_complete_cmd() does so.
* Change RX_RESET,  TX_RESET, GLOBAL_RESET to use ep_complete_cmd().

* Revert epconfig() to use inline RX_RESET, TX_RESET.
  That avoids accidentally setting IFF_UP, which  breaks both diskless boot,
  and "halt" commands issued before the interface is brought up.
1997-02-16 04:09:18 +00:00
jonathan 9821b30fe4 Use DELAY() after doing a TX_RESET or RX_RESET command.
Newer boards (e.g., Vortex) take  time to reset, and wedge on some machines.
Polling on S_COMMAND_IN_PROGRESS would be better, but that doesn't
work with xx_RESET commands on 3c509s.

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.

jonathan b00ac4cf2c * add epshutdown(), and establish as shutdown hook: see multiboot
comments in pr port-i386/2358: "if_ep/3C590 no longer working"
* Only call Vortex media-config code on PCI-attached devices, until
  we know if it works on ISA and EISA large-packet devices also.
* Fix typo in printf of MAC address
1996-12-29 17:01:58 +00:00
jonathan 23c1d14c64 * Add 100Mbit xcvr flags to epconfig():
look for 100mbit Xcvrs, print their names, add to ep_connectors.

* Print 10baseT as 10baseT, since media name (utp) is no longer a unique
  transceiver type.

* Redo FIFO memory size printing, also show Tx/Rx split (xxx isa 3c509?).

* Print MAC address on a separate line,  with 100Mbit media and fifo-ram
  info it no longer fits on the same line as media types.

* Comment the fact that the "connection" media-selection code just doesn't
  grok 100Mbit media.

* add code to look for 3c59x/3c90x media-select and autoconfig bits, though
  we don't yet dynamically probe media when the autoconfig bit is set
  (see previous bullet).

* XXX the whole connector/media code should be redone, perhaps a' la
  the BSDI ifmedia design.

cjs b1e0c7d657 Print the memory size on startup.
Add newline to `Interface disabled' printf and clean up formatting.
Change packet read/write code to align all reads and writes into
memory to an appropriate boundary for the I/O size. This also fixes
a bug where the trailing unaligned bytes (1-3 of them) would be
put in an additional mbuf even if there was enough space for them
in the one we were currently filling.
This has been tested on a 3c905 in an Alpha (32-bit I/O, alignment
required), a 3c905 in an i386 (32-bit I/O, alignment not required)
and a 3c509 in an i386 (16-bit I/O, alignment not required). It
should be tested on a 3c509 in an Alpha with an ISA bus, if somone
can manage to get the two items together.
There are still some bugs in the driver relating to initialisation;
on my Alpha with a 3c905 you need to do an `ifconfig ep0 down;
ifconfig ep0 up' after the initial ifconfig to make it start working.
Apparently there are also some problems with a 3c579 in an i386,
although a 3c905 in an i386 works just fine.

jonathan f6a82ef733 * 3c509s drop the low-oder bits of EP_THRESH_DISABLE (2047) on a write,
and the result reads back as zero.  Mask probe code accordingly.

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 300992c9ba Changed struct ifnet to have a pointer to the softc of the underlying
device and a printable "external name" (name + unit number), thus eliminating
if_name and if_unit.  Updated interface to (*if_watchdog)() and (*if_start)()
to take a struct ifnet *, rather than a unit number.

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>
