o Spell CardBus as CardBus, not Cardbus or CardBUS while I'm here.
The problem is that the code does a check for the granparent of
the Promise chip, if this is a bridge of the right type, we have
a TX4 on our hands, and need to handle that ones "issues".
Now the grandparent check cause subtle bugs in the newbus system,
mainly that pci_get_devid doesn't return an error value.
This patch works around the issue by using BUS_READ_IVAR() instead.
o Implement the thread killing interlock as described by jhb in arch@
while talking to markm.
o Hold Giant around cbb_insert()/cbb_remove(). Deep in the belly of
the vm code we panic if we don't hold this when we activate the memory
for reading the CIS.
o If we had to do the kludge alloc, then do a kludge free.
o Better resume code. Move the comments around. Force the socket state to
be querried. Ack the interrupts properly.
o Intercept the interrupt requests and keep a list of interrupts to service
ourselves. When the card attaches, set its OK bit. When we get a card
status change interrupt for that card, clear the OK bit. Don't call the
ISR if the OK bit is cleared. Iwasaki-san and yamamoto-san have both
sent me patches that fix the same problem this fixes, but at the pccard
level.
o Try to get the signalling of the thread to actually die. This might not be
100% right, but it is less wrong than before.
o Add a SIC next to a TI type that looks like it could be wrong, but isn't.

o Add comments about how we're doing the CIS activation.
o Add location and pnp info functions.
o Add better code to hopefully deal with ata cards better (and other drivers
that allocate resources that we didn't preallocate from the CIS). OLDCARD

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).
Note, we return the PCI pnp info, but in fact that's wrong to do
since that data is not defined for CardBus cards. CardBus says that
these registers are undefined and one should use the CIS to do
device matching. To date, all CardBus cards have had these
registered defined, no doubt because they are using common silicon
to produce both the PCI cards and the CardBus cards. However, it isn't
any worse than the rest of the system, so just note it in passing and
move on.
o Also sort prototypes while I'm here.
currently disabled):
o Don't use constants for the output parameter, use the iparam count as a
pointer to the first result location.
o Fix bits vs bytes counting problems.
o Split out the hardware and software normalization versions of modexp.
o Enable hardware normalization for chips that support it.
o On reset, disable hardware normalization for 582x and make sure the
chip is in little endian mode.
o Since sw normalization is now the only option, simplify normalization
handling.
Also fix RNG harvesting: disabling PK support (for the moment) had disabled
the MCR2 interrupt; consider both KEY support and RNG support when deciding
whether or not to enable it.

OpenBSD who got the code (or the idea) from the NetBSD tlp driver.
This gets some cardbus dc cards working (either completely or nearly
so). It also appears to get additional pci cards working, without
breaking working ones.
# Maybe some additional work is needed here. Also, the cardbus attachment
# might need to match on the CIS rather than on the vendor/device so we have
# a finer level of detail as to what the card is. Technically, the
# vendor/device fields are undefined for CardBus (even though most cards are
# using common silicon with pci models).
NB: But it will enable it in all kernels not having options "NO_GEOM"
Put the GEOM related options into the intended order.
Add "options NO_GEOM" to all kernel configs apart from NOTES.
In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.
There are currently three known issues which may force people to
need the NO_GEOM option:
boot0cfg/fdisk:
Tries to update the MBR while it is being used to control
slices. GEOM does not allow this as a direct operation.
SCSI floppy drives:
Appearantly the scsi-da driver return "EBUSY" if no media
is inserted. This is wrong, it should return ENXIO.
PC98:
It is unclear if GEOM correctly recognizes all variants of
PC98 disklabels. (Help Wanted! I have neither docs nor HW)
These issues are all being worked.

(1) Use namei() and devfs to discover devices rather than a hard-coded
MAKEDEV implementation. Once rootfs is in place, this will allow
Vinum to be used for the root file system partition.
(2) Pass FREAD to device opens so that GEOM will return sector size
rather than an error on attempts to read label data.
(3) Avoid clobbering return values from close_drive() and masking this
failure, resulting in a later divide by zero due to not having
updated the Vinum-cached sector size.
(4) Ignore failures from DIOCWLABEL as that appears not to be required
in the GEOM environment.
We've done testing in simple Vinum environments, but those with more
complex environments might want to give this a spin in DP2 and make
sure everything is up to speed.

Allocated IRQ will be used for PCI interrupt routing when ACPI is

people can easily notice the strange behavior if it happened.

fgetown() to take a reference to the pointer instead of a copy of the

dereferencing it.
