success and a proper errno value on failure. This makes it
consistent with cv_timedwait(), and paves the way for the
introduction of functions such as sema_timedwait_sig() which can
fail in multiple ways.
Bump __FreeBSD_version and add a note to UPDATING.

allocation was passed up to nexus. Now, we probe sysresource objects and
manage the resources they describe in a local rman pool. This helps
devices which attach/detach varying resources (like the _CST object) and
module loads/unloads. The allocation/release routines now check to see if
the resource is described in a child sysresource object and if so,
allocate from the local rman. Sysresource objects add their resources to
the pool and reserve them upon boot. This means sysresources need to be
probed before other ACPI devices.
Changes include:
* Add ordering to the child device probe. The current order is: system
resource objects, embedded controllers, then everything else.
* Make acpi_MatchHid take a handle instead of a device_t arg.
* Replace acpi_{get,set}_resource with the generic equivalents.

This does not change the queueing yet. These changes will follow in a
seperate commit. Same with the driver changes, which need case by case
evaluation.
__FreeBSD_version bump will follow.

conform to the rfc2734 and rfc3146 standard for IP over firewire and
should eventually supercede the fwe driver. Right now the broadcast
channel number is hardwired and we don't support MCAP for multicast
channel allocation - more infrastructure is required in the firewire
code itself to fix these problems.
in a TAILQ. Re-arrange some of the ecb elements so that they can stay
stable through alloc/free cycles while the rest get bzero'd.
- Use the tag_id from the ecb rather than fro the ccb. The latter is only
for target mode.
- Honor the ccb flags for tag_action when deciding whether to do a tagged
or untagged transaction.
- Re-arrange autosense completion so that it works correctly in failure
cases.
- Turn on the PI_TAG_ABLE flag so that CAM will send us tagged transactions.
This enables tagged queueing in the driver.

Also make device resets work, thanks to another typo.

is the actual name here) on EBus and which are PCF8584 (on systems having
a boot-bus controller the i2c are said to not be a PCF8584). Similar to the
SUNW,envctrl devices, onboard slaves for monitoring fans, temperatures and
such hang off of these i2c devices. But there's also stuff like EEPROMs
housing the hostid of the system and the boards usally have a connector to
add custom slave devices (on CP1500 there's actually a second PCF8584 with
its own I2C bus for these).
This driver already works fine but I'm not yet sure if access to the slave
devices on CP1400/CP1500 marked as "reserved for factory use" in the docs
should be blocked (most likely these are the voltage controllers wich aren't
meant to be controller by software and even not by the firmware). Once the
issues with polled mode are fixed in the common pcf(4) part in pcf.c, this
front-end should probably honour the poll-mode property of the i2c devices.
Tested on Ultra AXe and CP1500 (Netra t1 100).

- Use "envctrl" as the name when registering this module rather than "pcf";
we can't have "pcf" as the name for all pcf(4) front-ends or we would get
conflicts.

- s,pcf_,pcf_isa, to better reflect the purpose of this front-end and to
avoid conflicts.
- Don't use this front-end for attaching to EBus, declaring it as an EBus

its primary use is for the FEPS/FAS366 SCSI found in Sun Ultra 1e and 2
machines. Once the pci front-end is ported, this driver can replace the
amd(4) driver.
The code as-is is fairly stable. I've disabled tagged-queueing until I can
figure out a corruption bug related to it. I'm importing it now so that
people with these machines can (finally) stop netbooting and report bugs
before 5.3.
as otherwise the junk it contains may cause uhub_explore to give

errors I was seeing with a VIA UHCI controller:
uhub0: port error, restarting port 1
uhub0: port error, giving up port 1
all of the interface between the driver and the bus. This will enable
us to stop special casing eisa bus attachments in modules and treat them
like we treat all other busses.
In the longer run, we need to eliminate much (all?) of these interfaces
and switch to using the standard bus_alloc_resource(), but that's not
done right now.
# I've not updated the modules to include eisa, etc, just yet
Tested on: Compaq Proliant 3000/333 purchased for eisa work
mode. The 5704 apparently has some s00p3r s33kr1t registers for setting
the advertisement of pause frame ability (i.e flow control) when in
autoneg mode. If we don't set these registers correctly, we may not
be able to negotiate a proper link with some switches. (Symptom is that
the NIC reports the link as up (PCS synched) but no traffic can be
exchanged.)
