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.

265be3e08a Add new functions. Also add comments to existing functions. These
are needed for the pccard changes I've just committed.

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.

e14c13dae0 Minor changes to some of the interfaces.
Remove RF_PCCARD_ATTR in anticipation of removing it from sys/rman.h
Add interface for setting "attributes" of pccard/cardbus devices.

f27f6c0076 Add resource activation routines to pcic driver. Minor cleanup of
socket attach code.  We now have at least a chance for pccard devices
appearing in the future.

This is a snapshot of ongoing work.  Proceed at your own risk.
