93da209126 o Try to do 3.3V support better for the 6722 and 6729/30.
o Bite the bullet and create controller types for the 6729 and also for
  the 673x.  Rename the 672x to 6722.
o Define minimal extended register info (just register 0xa for reading VS[12]).

# I think the last version may have broken 673x controllers, but this should
# fix them.

Tested on the 6722, but not the 6729.

79c1672770 Order PCIC_INT_GEN bits large to small, like all other registers. 2001-08-05 06:59:32 +00:00

53af1c8a3d TI cardbus bridges, 12xx and newer, have an interesting register. It
is the diagnostics register at offset 0x93.  When bit 5 is set in this
register, bits 4-7 in ExCA register 0x5 being 0000 are required for
pci interrupt routing.  When it is clear, then bit 4 of ExCA register
0x3 is used to enable it.

The only other issue is that when you route interrupts this way, you
must read ExCA register 0x4 in order to clear the interrupt, else you
get an interrupt storm.

Deal with this requirement by setting things up.  It is believed that
this won't hurt other chipsets, but other chipsets may require their
own work arounds.

11cedf79a8 On PC-98, map IRQ 6 to IRQ 7 at the pcic level. That is, when we're
told to use IRQ 6, progam the pcic to use irq 7 instead.  Evidentally,
at least some of the cards are wired this way.  If you want to use irq
6, configure it.  All the mapping is done just before we set the
interrupt registers.  See [FreeBSD98-testers 5064] for details.

Added commentary about valid interrupts on some CBUS pc98 CL PD6722
based cards.

a8ed536b94 Add better support for the Ricoh 5C296 and 5C396 chips. These chips
have a slightly different 3.3V support than the other clones, so
compensate as best we can.  Note: 3.3V support is untested since I do
not have any 3.3V cards that I know of to test it with.

57462c010c Next step on the road to pci: power taming.
Work through the various power commands and convert them from a "is
this a foo controller or a foo' controller or a foo''' controller" to
a cabability based scheme.  We have bits in the softc that tell us
what kind of power control scheme the controller uses, rather than
relying on being able to enumerate them all.  Cardbus bridges are
numerous, but nearly all implement the i82365sl-DF scheme (well, a few
implement cirrus CL-PD67xx, but those were made by Cirrus Logic!).

Add a pointer back to the softc in each pcic_slot so we can access
these flags.

Add comments that talk about the issues here.  Also note in passing
that there are two differ Vpp schemes in use and that we may need to
adjust the code to deal with both of them.  Note why it usually works
now.

We have 5 power management modes right now: KING, AB, DF, PD and VG.
AB is for the i82365 stpes A, B and C.  DF is for step DF.  PD is the
cirrus logic extensions for 3.3V while VG is the VADEM extensions for
3.3V.  KING is for the IBM KING controller found on some old cards.
# I'm looking for one of those old cards or a laptop that has the KING
# bridge in it.

We have to still cheat and treat the AB parts like the DF parts
because pci isn't here yet.  As far as I can tell, this is harmless
for actual old parts and necessary to work with 3.3V cards in some
laptops.

This almost eliminates all tests for controller in the code.  There
are still a few unrelated to power that need taming as well.

69ffb52731 Two comments and one bug fix:
o Add defines for the VS[12]# bits in register 0x16.
o Add comment about what we're doing reading register 0x16 (PCIC_CDGC)
  in the DF case.
o Check bit VS1# rather than a random bit I was checking due to a bogus
  transcrition on my part from nakagawa-san's article.
o Add note about IBM KING and 3.3V operation from information larned from
  wildboard.

08db6b5c8e It turns out that Intel's i82365sl-DF step has the same ID as the VLSI
82C146.  The Intel i82365SL-DF supports 3.3V cards.  The Step A/B/C
parts do not appear to support this.  This is hard to know for sure
since it was deduced from "compatible" parts' data sheets and the
article mentioned below.

Rework the VLSI detection to be a little nicer and not depend on
scanning cards twice.  This would allow bad VLSI cards to coexist with
a good intel card, for example.  We now detect i82365SL-DF cards where
before we'd detect a VLSI.  For the most part, this is good, but we
run a small chance of detecting a single slot 82C146 as a i82365SL-DF.
Since I can't find a datasheet for the 82c146, I don't know if this is
a problem or not.

This work is based on an excellent article, in Japanese, by NAKAGAWA,
Yoshihisa-san that appeared in FreeBSD Press Number 4.  He provided a
patch against PAO3 in his article.  Since the pcic.c code has changed
some since then, I've gone ahead and cleaned up his patch somewhat and
changed how the code detects the buggy '146 cards.

I also removed the comment asking if there were other cards that
matched the 82C146 since we found one and additional information isn't
necessary.

7402675de4 First cut at bringing NEC PC98 original pccard bridge code back into
FreeBSD.  This code doesn't work just yet, but does compile.  We need
to start indirecting via the cinfo pointers, rather than directly
calling pcic_*.  There may be other issues as well, but you gotta
start somewhere.

36260de0cf Lots of minor cleanup, plus a couple of interesting things.
o Attempt to disable the slot when we detect that there are problems with
  it in our ISR.  This should make polling mode work better for more cards,
  but more work may be needed.  This "disabling" sets the card interrupt
  register to 0.  This worked for me for lots of tests in polling mode.
o Now that I've found datasheets, fix a boatload of magic numbers in the
  source to make it easier to understand.
o Use a table of names rather than a big case statement.
o Cull a few of the "unused" controller types that we map to other times
  that were a vestiage of PAO code that we never merged in the same way.
o Enforce legal IRQs.  You are no longer allowed to try to use IRQs that
  will fail on all known ISA/PCI <-> PCMCIA bridges.  The bridges do not
  have pins for these illegal interrupts, and all of them are listed as
  reserved and/or illegeal in the datasheets depending on which one you
  look at.
o Add comments about how IBM-AT based computers and NEC PC-98 based computers
  map these interrupts and which ones are valid.
o Always clear the bit that steers the management interrupt either to the
  value listed in the PCIC_STAT_INT register.  I've seen this bit get set
  on suspend/resume and after windows boot, and it does't hurt to clear it.
  NOTE: this might mean we can share this interrupt in the future.

595166f0f7 Add support for PnP ISA cards, and some laptop PnP support:
o break out some of the probe routine the allocation of resources
  into an attach routine
o Recognize PnP ids
o Allocate IRQ per card rather than per system
o Better polling reporting
o Remove unneeded include files in slot.h
o store a pseudo unit number on each device we find.
o Pass a unit number to interrupt/timeout routine and use it for polling
  the hardware.

Tested on: My VAIO and with the Linksys pccard reader.

6e73d499d8 Add probing support for the vadem VG365 and the Vadem VG465 pcic chips.
We do the same thing we do with all the other Vadem chips and print the
right identification for these chips.  Tested with the 365, and inferred
for the 465.

This allows the cheapo PCMCIA card that I got from necx to print the right
chip number on boot.

01f370b672 Modem cards send the speaker audio (dialing noises) to the host's
speaker.  Cirrus Logic PCIC chips must enable this.  There is also a Low
Power Dynamic Mode bit that claims to reduce power consumption by 30%,
so enable it and hope for the best.

b805b39e43 1. i82365.h: Chip identifiers should not be #ifdef PC98. Add identifier
(pt. unused) for TI PCI1130.

2. pccard.c: PCIC_RESUME_RESET is now (also) a sysctl.  (Never make it
    a #ifdef if it can be made a sysctl!)

3. pcic.c: make getb() and putb() proper member functions of struct
    pcic_slot.  Add a couple of missing casts.

ea5ff881da Don't rely on the card 'automatically' powering up when we probe it.
On some laptops, this doesn't work (ie; IBM 75x series), so force it
to power on.

With this modification, I am able to read the tuples off 4 different
PCMCIA cards on my ThinkPad.
