this gives us several benefits, including:
* easier extensibility- new optional methods can be added to
ac97/mixer/channel classes without having to fixup every driver.
* forward compatibility for drivers, provided no new mandatory methods are
added.
- Break out the /dev/pci driver into a separate file.
- Kill the COMPAT_OLDPCI support.
- Make the EISA bridge attach a bit more like the old code; explicitly
check for the existence of eisa0/isa0 and only attach if they don't
already exist. Only make one bus_generic_attach() pass over the
bridge, once both busses are attached. Note that the stupid Intel
bridge's class is entirely unpredictable.
- Add prototypes and re-layout the core PCI modules in line with
current coding standards (not a major whitespace change, just moving
the module data to the top of the file).
- Remove redundant type-2 bridge support from the core PCI code; the
PCI-CardBus code does this itself internally. Remove the now
entirely redundant header-class-specific support, as well as the
secondary and subordinate bus number fields. These are bridge
attributes now.
- Add support for PCI Extended Capabilities.
- Add support for PCI Power Management. The interface currently
allows a driver to query and set the power state of a device.
- Add helper functions to allow drivers to enable/disable busmastering
and the decoding of I/O and memory ranges.
- Use PCI_SLOTMAX and PCI_FUNCMAX rather than magic numbers in some
places.
- Make the PCI-PCI bridge code a little more paranoid about valid
I/O and memory decodes.
- Add some more PCI register definitions for the command and status
registers. Correct another bogus definition for type-1 bridges.
but serves to work around some uncleanliness whereby the ISA bus is not
found on Alpha systems with PCI:EISA bridges due to the lack of EISA code
for the Alpha.
held and panic if so (conditional on witness).
- Change witness_list to return the number of locks held so this is easier.
- Add kern/syscalls.c to the kernel build if witness is defined so that the
panic message can contain the name of the offending system call.
- Add assertions that Giant and sched_lock are not held when returning from
a system call, which were missing for alpha and ia64.
- Make pccbb/cardbus kld loadable and unloadable.
- Make pccbb/cardbus use the power interface from pccard instead of inventing its own.
- some other minor fixes
using a cardbus based system with pccbb providing the pcic interface).
Something isn't quite right.. when the driver allocates and activates
its resources, the IO space that was requested reads as all zeros (versus
the original 0xff's as it normally is when there is no device responding).
Also, deactivate the resources before releasing them. OLDCARD doesn't
seem to care but NEWCARD/CARDBUS get rather unhappy if you release
a resource that hasn't been deactivated yet.
Make pcic_p.c only compile with oldcard kernels.

- Layout reorganisation to enhance portability. The driver now has
a relatively MI 'core' and a FreeBSD-specific layer over the top.
Since the NetBSD people have already done their own port, this is
largely just to help me with the BSD/OS port.
- Request ID allocation changed to improve performance (I'd been
considering switching to this approach after having failed to come
up with a better way to dynamically allocate request IDs, and seeing
Andy Doran use it in the NetBSD port of the driver convinced me
that I was wasting my time doing it any other way). Now we just
allocate all the requests up front.
- Maximum request count bumped back to 255 after characterisation
of a firmware issue (off-by-one causing it to crash with 256
outstanding commands).
- Control interface implemented. This allows 3ware's '3dm' utility to
talk to the controller. 3dm will be available from 3ware shortly.
- Controller soft-reset feature added; if the controller signals a
firmware or protocol error, the controller will be reset and all
outstanding commands will be retried.

This commit adds support for Xircom X3201 based cardbus cards.
Support for the TDK 78Q2120 MII is also added.
IBM Etherjet, Intel and Xircom cards uses these chips.
Note that as a result of this commit, some Intel/DEC 21143 based cardbus
cards will also attach, but not get link. That is being looked at.
Files:
dev/cardbus/cardbus.c
dev/cardbus/cardbusreg.h
dev/cardbus/cardbusvar.h
dev/cardbus/cardbus_cis.c
dev/cardbus/cardbus_cis.h
dev/pccbb/pccbb.c
dev/pccbb/pccbbreg.h
dev/pccbb/pccbbvar.h
dev/pccbb/pccbb_if.m
This should support:
- cardbus controllers:
* TI 113X
* TI 12XX
* TI 14XX
* Ricoh 47X
* Ricoh 46X
* ToPIC 95
* ToPIC 97
* ToPIC 100
* Cirrus Logic CLPD683x
- cardbus cards
* 3c575BT
* 3c575CT
* Xircom X3201 (includes IBM, Xircom and, Intel cards)
[ 3com support already in kernel, Xircom will be committed real soon now]
This doesn't work with 16bit pccards under NEWCARD.
Enable in your config by having "device pccbb" and "device cardbus".
(A "device pccard" will attach a pccard bus, but it means you system have
a high chance of panicing when a 16bit card is inserted)
It should be fairly simple to make a driver attach to cardbus under
NEWCARD -- simply add an entry for attaching to cardbus on a new
DRIVER_MODULE and add new device IDs as necessary. You should also make
sure the card can be detached nicely without the interrupt routine doing
something weird, like going into an infinite loop. Usually that should
entail adding an additional check when a pci register or the bus space is
read to check if it equals 0xffffffff.
Any problems, please let me know.

now in dirs called sys/*/random/ instead of sys/*/randomdev/*.
Introduce blocking, but only at startup; the random device will
block until the first reseed happens to prevent clients from
using untrustworthy output.
Provide a read_random() call for the rest of the kernel so that
the entropy device does not need to be present. This means that
things like IPX no longer need to have "device random" hardcoded
into thir kernel config. The downside is that read_random() will
provide very poor output until the entropy device is loaded and
reseeded. It is recommended that developers do NOT use the
read_random() call; instead, they should use arc4random() which
internally uses read_random().
Clean up the mutex and locking code a bit; this makes it possible
to unload the module again.

How it works:
--
Basically ifs is a copy of ffs, overriding some vfs/vnops. (Yes, hack.)
I didn't see the need in duplicating all of sys/ufs/ffs to get this
off the ground.
File creation is done through a special file - 'newfile' . When newfile
is called, the system allocates and returns an inode. Note that newfile
is done in a cloning fashion:
fd = open("newfile", O_CREAT|O_RDWR, 0644);
fstat(fd, &st);
printf("new file is %d\n", (int)st.st_ino);
Once you have created a file, you can open() and unlink() it by its returned
inode number retrieved from the stat call, ie:
fd = open("5", O_RDWR);
The creation permissions depend entirely if you have write access to the
root directory of the filesystem.
To get the list of currently allocated inodes, VOP_READDIR has been added
which returns a directory listing of those currently allocated.
--
What this entails:
* patching conf/files and conf/options to include IFS as a new compile
option (and since ifs depends upon FFS, include the FFS routines)
* An entry in i386/conf/NOTES indicating IFS exists and where to go for
an explanation
* Unstaticize a couple of routines in src/sys/ufs/ffs/ which the IFS
routines require (ffs_mount() and ffs_reload())
* a new bunch of routines in src/sys/ufs/ifs/ which implement the IFS
routines. IFS replaces some of the vfsops, and a handful of vnops -
most notably are VFS_VGET(), VOP_LOOKUP(), VOP_UNLINK() and VOP_READDIR().
Any other directory operation is marked as invalid.
What this results in:
* an IFS partition's create permissions are controlled by the perm/ownership of
the root mount point, just like a normal directory
* Each inode has perm and ownership too
* IFS does *NOT* mean an FFS partition can be opened per inode. This is a
completely seperate filesystem here
* Softupdates doesn't work with IFS, and really I don't think it needs it.
Besides, fsck's are FAST. (Try it :-)
* Inodes 0 and 1 aren't allocatable because they are special (dump/swap IIRC).
Inode 2 isn't allocatable since UFS/FFS locks all inodes in the system against
this particular inode, and unravelling THAT code isn't trivial. Therefore,
useful inodes start at 3.
Enjoy, and feedback is definitely appreciated!

While here, work around a strange quirk in config(8) that I do not yet
understand. Rearrange which atapi* files have 'optional' vs. 'count'
so that you can have atapifd without atapicd. The only difference should
be that this works instead of having a link error because atapi-all.o got
left out of the kernel.
- Move all register I/O into acpi_io.c
- Move event handling into acpi_event.c
- Reorganise headers into acpivar/acpireg/acpiio
- Move find-RSDT and find-ACPI-owned-memory into acpi_machdep
- Allocate all resources (except those detailed only by AML)
as real resources. Add infrastructure that will make adding
resource support to AML code easy.
- Remove all ACPI #ifdefs in non-ACPI code
- Removed unnecessary includes
- Minor style and commenting fixes
