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.
that it looks for an acceptible one. Once it finds it, it should set
the resources for the device. I say "should" because I've not written
that. Also set an ivar for the child of pccard. Minor fix to the
attach message printed, we lose the slot number, which I'll have to
restore later. Adjust the pccard ivar so that we can save the
function that corresponds to this driver so we can enable and disable
it more easily. Save a pointer to the function so we know what we're
dealing with.
There should be some way for the driver to specify which cfg it wants
to activate. For now the pccard_function_init function just picks
one, but we'll have to revisit this going forward. I'm not doing it
now because I'd need some way to activate the card many times and I'm
not sure that is desirable or even safe with some cards.
I've done this by having requests to allocate memory propigate up the
tree. We'll see how well this works and reevaluate if it isn't
working well. Also initialize ptr in the tuple. As well as minor
reorg of memory allocation. Likely need to do similar things for I/O
when the time comes.
I've move all defines from pccardchip.h into pccardvar.h and
eliminated pccardchip.h.
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.
Remove RF_PCCARD_ATTR in anticipation of removing it from sys/rman.h
Add interface for setting "attributes" of pccard/cardbus devices.
Minor formatting nits.
o ifdef out pccardchip.h (almost all of it, there are dangling bits
o Add rid/res members to pccard_function
o remove pct/pch from pccard_softc
o map memory properly in scan_cis (almost, see XXX for more work)
o manage ccr.
o remove bogus comment I added about touching the ccr being a layering
violation for pccard. It is properly done at that level.
o More function prototyping
layer is trying to access the now unexistant chip functions.
o Added DEVPRINTF which is like DPRINTF only calls device_printf.
o Made it possible to define PCICDEBUG
o Remove ph_parent and use the softc pointer sc instead in pcic_handle.
o Remove all references to dv_xname
o Add some debug messages.
o enable MI attach/detach calling for pccard.
o convert pcic_chip_socket_{en,dis}able to pcic_{dis,en}able_socket
and connect them to the power_{enable,disbale}_socket.
o Remove pccard pointer from pcic_softc.
o GC some unused pccard functions.
o Convert pccard_chip_socket* to POWER_ENABLE_SOCKET
o kill pccard_attach_args.
o power_if.m updates. More to come.
now, but we're getting interrupts!
o Add pcic_suspend/pcic_resume so we can detach our children on suspention
and fix the state of the pcic on resume.
o Remove some unused parts of softc.
o Centralize resource activation/deactivation for pcic bridge chip in
the stylistic pcic_activate/pcic_deactivate.
o Add bus_print_child method so we can see the pccard attachment.
o Add pcic_identify in an attempt to make it possible to automatically id
the pcic devices. This works great, but we cannot divine the irq to use
from this method, nor the memory hole. For the moment, KLUDGE irq to be
10 and memory hold to be 0xd0000.
o Loose the pnp probe stuff. This may be a big mistake, but it is easy
enough to add back later. I did this so the identify routines can do their
thing unmolested by pnp information. The whole identify thing may be a bad
idea to be ripped out later.
o change return type of pcic_intr to void, make it static and ripple
this through the code.
o Add explicit call to bus_generic_attach at the end of pcic_attach to
get any children probed/attached.
o add some comments about future directions/questionable things being
done at different layers, etc.
o Implement memory and I/O activation/deactivation. irq not handled.
o switch pcic_chip functions around to use more convenient types.
o kill __P and most of the old K&R prototypes just to be mean.
o minor other nits
device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

it would work), or a specialized one. Most of these have been
creatively stolen from pccard_nkb, which in turn stole from isa
showing that generic bus_ versions of bus_{set,get,delete}_resource
might be profitable.
Fix a couple of minor bugs introduced in the last round of updates
from NetBSD.
Start on the pccard_ivar structure which will hold the resources and
slot number.
Add tcic as a possible attachment for pccard and rename the attachment
for pcicx to pcic since the name has changed since I originally wrote
this stuff.
Next up:
stringing together the various memory and I/O
allocation/mapping primitives in i82365.c, final touches on the isa
attach routine and other fun stuff in that line of attach.
incomplete and likely has problem. The code was originally pcmcia,
but I renamed it to pccard and made it compile on FreeBSD -current. I
converted SIMPLEQ to STAILQ as well as a few sc->dev.xname ->
device_printf changes. This is a green port of fairly mature code.
I derived this work from the FreeBSD newconfig project
(http://www.jp.freebsd.org/newconfig). Any problems with it are
likely introduced by me.
