infrastructure. It's not perfect, but it's a lot better than what
we've been using so far. The following rules apply to this:
o BSD component names should be capitalised
o Layer names should be taken from the non-CA set for now. We
may elect to add some new BSD-specific layers later.
- Make it possible to turn off selective debugging flags or layers
by listing them in debug.acpi.layer or debug.acpi.level prefixed
with !.
- Fully implement support for avoiding nodes in the ACPI namespace.
Nodes may be listed in the debug.acpi.avoid environment variable;
these nodes and all their children will be ignored (although still
scanned over) by ACPI functions which scan the namespace. Multiple
nodes can be specified, separated by whitespace.
- Implement support for selectively disabling ACPI subsystem components
via the debug.acpi.disable environment variable. The following
components can be disabled:
o bus creation/scanning of the ACPI 'bus'
o children attachment of children to the ACPI 'bus'
o button the acpi_button control-method button driver
o ec the acpi_ec embedded-controller driver
o isa acpi replacement of PnP BIOS for ISA device discovery
o lid the control-method lid switch driver
o pci pci root-bus discovery
o processor CPU power/speed management
o thermal system temperature detection and control
o timer ACPI timecounter
Multiple components may be disabled by specifying their name(s)
separated by whitespace.
- Add support for ioctl registration. ACPI subsystem components may
register ioctl handlers with the /dev/acpi generic ioctl handler,
allowing us to avoid the need for a multitude of /dev/acpi* control
devices, etc.
We must force payload alignment to a longword boundary to make the
alpha happy. This should stop the driver from trapping on the alpha
when the interface is ifconfig'ed (actually, when the first frame is
received).
USB WebCams, using a patch from Peter Housel.
With this change ugen, and with Peter's 'vid' program
in ports/graphics/vid, we can capture single images from USB Cameras
using the OmniVision OV511 chipset (including some models of the
Creative WebCam 3)
NetBSD merged in Peter's patch to their ugen.c file
several months ago, so this brings us back in line.

Change a few indentations to tabs.
Change the functions to use ANSI sytle parameters.
This lowers the diffs between our copy of ugen.c and NetBSD's copy

Add a test against isp->isp_osinfo.islocked prior to trying to see
whether --isp->isp_osinfo.islocked is zero to cause us to unlock
(non-SMPLOCK case).
in the future:
o Remove pcic_softc from pcic_handle and replace it with a void *
o Reduce dependence on accessing softc via a pcic_handle
Minor cleanups:
o Define a macro to count the size of an array and use it.
o Minor whitespace alignment
o make no slots found a printf not a panic.
HID passed in as an argument at all; callers are typically going to be
sending us static strings anyway.

patch, I can now boot with PNP-OS YES in my BIOS no differently than
PNP-OS NO (which is a good thing since Windows hangs with PNP-OS NO).

- standardise error reporting for commands
- simplify the driver-to-controller bio transfer
- add bio in/out accounting
- correctly preserve the command ID in twe_ioctl (thanks to joel@3ware)
There is no more TAILQ fifo to harvest the entropy; instead, there
is a circular buffer of constant size (changeable by macro) that
pretty dramatically improves the speed and fixes potential slowdowns-
by-locking.
Also gone are a slew of malloc(9) and free(9) calls; all harvesting
buffers are static.
All-in-all, this is a good performance improvement.
Thanks-to: msmith for the circular buffer concept-code.
(specifically, how many entries we've looked at so far). Maintain
interrupt instrumentation. Use USEC_SLEEP instead of USEC_DELAY in
a number of places (this allows us to drop locks and sleep instead
of spin). Track changes to configuration options for topology preference.
Fix botched order of printout for Channel, Target, Lun.
like the args to the config space accessors these functions replaced.
This reduces the likelyhood of overflow when the args are used in
macros on the alpha. This prevents memory management faults when
probing the pci bus on sables, multias and nonames.

- Use ACPI_PHYSICAL_ADDRESS
- RSDT -> XSDT
- FACP -> FADT
- No APIC table support
- Don't install a global EC handler; this has bad side-effects
(it invokes _REG in *all* EC spaces in the namespace!)
- Check for PCI bus instances already existing before adding them
but a hack! Add `flags 0x8000' to the psm driver to enable it.
The psm driver will try to get out of out-of-sync situation
by disabling the mouse and immediately enable it again.
If you are seeing this out-of-sync problem because of an
incompetent(?!) KVM switch, this hack will NOT be good
for you. However, if you are occasionally seeing the
problem because of lost mouse interrupt, this might help.
4) The cardbus CIS code treats the CIS_PTR as a mapping register if
it is mentioned in the CIS. I don't have a spec handy to understand
why the CIS_PTR is mentioned in the CIS, but allocating a memory range
for it is certainly bogus. My patch ignores bar #6 to prevent the
mapping.
[The pccard spec says that BAR 0 and 7 (-1 and 6 in thic case since we
did a minus one) is "reserved". The off by 1 error has been fixed.
also bar=5 is invalid for IO maps, so we check it.]
5) The CIS code allocated duplicate resources to those already found
by cardbus_add_resources(). The fix is to pass in the bar computed
from the CIS instead of the particular resource ID for that bar,
so bus_generic_alloc_resource succeeds in finding the old resource.
[fixed, also removed superfluous (and incorrect) writing back to the
PCI config space.]
7) The CIS code seems to use the wrong bit to determine rather a particular
register mapping is for I/O or memory space. From looking at the
two cards I have, it seems TPL_BAR_REG_AS should be 0x10 instead
of 0x08. Otherwise, all registers that should be I/O mapped gain
a second mapping in memory space.
[Oops, the spec does say 0x10..., fixed]

Fix amr_map_command so that 40LD-specific commands get the scatter-gather
list count in the right place. I don't understand why AMI did it like
this, but now the AMI MegaManager can talk to the newer (1600 and later)
controllers.
Remove an unused variable.
Include <machine/clock.h> when necessary.
Tweak some debugging levels to make things more intelligible.
io or memory space access enabled. This patch defers the setting
of these bits until after all of the mapping registers are probed.
It might be even better to defer this until a particular mapping
is activated and to disable that type of access when a new
register is activated.
2) The PCI spec is very explicit about how mapping registers and
the expansion ROM mapping register should be probed. This patch
makes cardbus_add_map() follow the spec.
3) The PCI spec allows a device to use the same address decoder for
expansion ROM access as is used for memory mapped register access.
This patch carefully enables and disables ROM access along with
resource (de)activiation.
This doesn't include the prefetching detection stuff (maybe later when code is written to actually turn on prefetching). It also does not use the PCI definitions (yet, I'll try to put this in all at once later)

- 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
