(1) Align to 64k for the CIS. Some cards don't like it when we aren't
aligned to a 64k boundary. I can't find anything in the standard
that requires this, but I have 1/2 dozen cards that won't work at
all unless I enable this.
(2) Sleep 1s before scanning the CIS. This may be a nop, but has little
harm.
(3) The CIS can be up to 4k in some weird, odd-ball edge cases. Since we
have limiters for when that's not the case, it does no harm to increase
it to 4k.
#1 was submitted, in a different form, by Carlos Velasco.
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.
are all bogus, and the cards that don't decode things quite right
often have hundreds of them. This will fix starvation of small dmesg
buffers and allow better debugging to happen. I thought about adding
an override, but there is such a thing as too many knobs. :-)
to what is in NetBSD. I have a few cards that tickles this bug, and
this just keeps us from panicing. It doesn't actually fix the problem
(that will happen once I figure out why some cards hate the address
their CIS is mapped to high memory).
give us slightly better error checking than before and interpret what
default bits mean better. See the NetBSD CVS tree for the authors of
these changes (revs 1.10 .. 1.17).
allows us to properly parse cards with attribute memory based CIS that
before wouldn't parse correctly, sometimes with a panic. This allows
me to get my 3C562 modem/ethernet card to fail to attach due to
problems in the ep and sio drivers rather than due to problems in the
CIS parsing code :-).
We weren't setting the address to jump to for the function entries.
This caused us to only work when the addional entries were after the
first ones. On the 3C562/3C563 card this was not the case.
We were also mapping Attribute memory when common memory was asked for
in the target of the LONGLINK_{A,C} or LONGLINK_MFC.
My IBM Home And Away Modem/LAN card still fails for reasons unknown.
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.
Pass sc->dev rather than a bogusly cast pccard_softc *sc.
This allows us to insert and remove cards w/o panicing the kernel.
However, the cis isn't mapped in, so the pccard_scan_cis function
fails.
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
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
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.
