26db48b9b2 Add a much-requested feature: The ability for pccard attachments to
scan the CIS for interesting tuples.  95% of what can be obtained from
the CIS is harvested by the pccard layer and presented to the user in
standard function calls.  However, there are special needs at times
where the standard stuff doesn't suffice.  This is for those special
cases.

CARD_SCAN_CIS(device_get_parent(dev), function, argp)
	scans the CIS of the card, passing each tuple to function with
	the tuple and argp as its arguments.  Returning 0 continues the scan,
	while returning 1 terminates the scan.  The value of the last
	invocation of function is returned from this function.

int (*pccard_scan_t)(struct pccard_tuple *tuple, void *argp)
	function called for each tuple.  Elements of the CIS tuple can be
	read with pccard_tuple_read_{1,2,3,4,n}().  You are reading
	the actual tuple memory each time, in case your card has
	registers in the CIS.

# I suppose these things should be documented in pccard(4) or something like
# that.

# I plan on unifying cardbus CIS support in a similar way.

77ab642f58 Remove more deadwood that never got implemented in NEWCARD, since NEWCARD
went a different direction than was anticipated when these compatibility
shims were added.

78ac8a9391 Remove card_get_function. It looks like it was intended to be a
bridge between OLDCARD and NEWCARD for drivers to inquire after the
function number (eg, 0, 1, 2).  Nobody ever used it, so retire it
with honors.  NEWCARD never implemented it, and the same information
can be obtained by the pccard_get_function_number().

a294cdb6b5 o move the cis tuple definitions into a common file.
o minor optimization of cardbus_cis processing.  Remove a bunch of generic
  entries that are handled by generic.
o no longer need the card_get_type stuff.

bcaa6b0541 MFp4:
o Always release the resources on device detach.
o Attach resources the same with driver added as we do we do in the insert
  case (maybe this should be a routine).
o signal the wakeup of the thread on resume instead of trying to force an
  interrupt.
o Minor debug hacks.
o use 0xffffffff instead of -1 for uint32_t items.
o Don't complain when we're asked to detach no cards.  This is normal.
o Eliminate the now worthless second parameter to card_detach_card.
o minor style(9)isms

Some of these patches may be from: iwasaki-san, jhb, iadowse

2d7a3e94bd o Dike out the bogus reprobe stuff. It was getting in the way of newbus' own
reprobe code working.  This bogusness was thrust upon me.
o Don't delete the device if no drivers attach.  I had thrust this bogusness
  upon others.

These two changes make kldload of a pccard driver work again.

c1bb793bbb Eliminate the need for pccard_common.c by moving the function inline
in the .h file.  Make it static __inline to make sure that it doesn't
wind up defined in any files.

Also, fix a typo that said null_do_attach instead of null_do_probe.

63fa9f4c0d Part two of this NEWCARD update:
Briefly, the significant changes include:
 * Way better resource management in pccbb, pccard and cardbus.
 * pccard hot-removal now appears to work.
 * support pre-fetchable memory in cardbus.
 * update cardbus to support new pci bus interface functions.
 * Fix CIS reading to no longer use rman_get_virtual().

What's not there, but in the works:
 * pccard needs to do interrupt properly and not read the ISR on single
   function cards.
 * real resource management for pccard
 * a complete implementation of CIS parsing
 * need to look into how to correctly use mutex in pccbb

c83acdc307 Non-functional changes to NEWCARD stuff.
This is the first part of a two-part update to NEWCARD.  Changes in this
commit are non-functional, and includes the following:
 * indentation and other changes to meet style(9).
 * other minor style consistancy changes
 * addition of comments
 * renaming of device_t variables to be consistant across all of NEWCARD.

(note that not all style violations are fixed in this commit -- those that
 aren't will be clobbered by the next commit.)

c33c1284cb First step towards making loadable modules independent of having
pccard in the kernel for those drivers with pccard attachments.  This
makes the compat layer a little larger by introducing some inlines,
but should almost make it possible to have independent attachments.
The pccard_match function are the only one left, which I will take
care of shortly.

486d464d74 o Now that I've had time to test the new interface, reintegrate it back in.
o Fix OLDCARD to use the new interface.
o Rename the offsetp argument to deltap to more closely reflect what it
  is returning (it returns the delta from the requested value to the actual
  value).
o Remove duplicate $FreeBSD$ in pccbb.c
o Allow deltap to be NULL.
o Convert new isa pcic driver and add XXX comments that this function isn't
  actually implemented there (which means that NEWCARD pccard stuff won't
  work there until it is).
o Revert attempts to make old inferface work in NEWCARD.

1bc96f7afd Undo the interface change to CARD_GET_MEMORY_OFFSET. It wasn't tested
by even a compile of the OLDCARD code, was unapproved by me the keeper
of OLDCARD and broke OLDCARD and the ray driver.

Adjust new code to cope with the older interface.

If the interface changes in the future, it ***MUST*** be cleared by me
so that the OLDCARD impacts taken into account.  It code in card_if.m
is used jointly by both OLDCARD and NEWCARD.

0c95c70577 * Better kld support in pccbb/cardbus
- pccbb no longer needs to remember whether a card is inserted.
  - pccbb reissues insertion on load of cardbus/pccard modules.
  - got rid of unnecessary delays in power functions.
  - Cardbus children are no longer deleted if probe/attach fails.
  - non-attached child devices are reprobed at driver_added.

* CARD interface to read CIS
  - added card_cis_read/card_cis_free interface to read arbitrary CIS
    data.  This currently is only implemented in cardbus.

* pccard begins to work
  - pccard can now use higher memory space (and uses it by default).
  - set_memory_offset interface changed.
  - fixed ccr access, which was broken at multiple locations.
  - implement an interrupt handler - pccard can now share interrupts.
  - resource alloc/release/activate/deactivate functions gutted: some
    resources are allocated by the bridge before the child device is
    probed or attached.  Thus the resource "belongs" to the bridge, and
    the pccard_*_resource functions need to fudge the owner/rid.
  - changed some error conditions to panics to speed debugging.

* Mutex fix - Giant is entered at the beginning of thread

c3342a3d99 Oops, broke newcard because I forgot to commit this in my last round of changes to pccbb.c 2000-11-28 15:50:13 +00:00

2276cee521 Implement indirection in the pccard probe/attach. This should make it
possible to have different probe/attach semantics between the two
systems and yet still use the same driver for both.

Compatibility methods for OLDCARD drivers.  We use these routines to make
it possible to call the OLDCARD driver's probe routine in the context that
it expects.  For OLDCARD these are implemented as pass throughs to the
device_{probe,attach} routines.  For NEWCARD they are implemented such
such that probe becomes strictly a matching routine and attach does both
the old probe and old attach.

compat devices should use the following:

	/* Device interface */
	DEVMETHOD(device_probe),	pccard_compat_probe),
	DEVMETHOD(device_attach),	pccard_compat_attach),
	/* Card interface */
	DEVMETHOD(card_compat_match,	foo_match),	/* newly written */
	DEVMETHOD(card_compat_probe,	foo_probe),	/* old probe */
	DEVMETHOD(card_compat_attach,	foo_attach),	/* old attach */

This will allow a single driver binary image to be used for both
OLDCARD and NEWCARD.

Drivers wishing to not retain OLDCARD compatibility needn't do this.

ep driver minorly updated.

sn driver updated more than minorly.  Add module dependencies to allow
module to load.  Also change name to if_sn.  Add some debugging code.
attempt to fix the cannot allocate memory problem I'd been seeing.
Minor formatting nits.

3a6352bdee checkpoint latest pccard/pcic hacking:
o Eliminate cross calls between the devices.  Instead move to using the
  newbus messaging system.  Added three new card calls: attach_card,
  detach_card, get_type.
o Eliminate interrupt routine in pccard we never use.
o Move from deactivate to detach for removing cards.
o Start mapping CIS memory, but it is broken and causes panics.  At least
  it is closer to working than before.
o Eliminate struct device everywhere.  It was bogus.
o Initialize softc for pccard device so we have valid pointers to
  ourselves.
o Implement routine to find the pcic ivar for a child device of the pccard so
  we can use it to talk to the pcic hardware.
o Lots of minor tiding up.

This version now panics when we try to read the CIS.  The next batch
of work to make this work is what was outlined in my posting to mobile
about resource allocation and such.
