PCI bus' one as the default one, and explicitely use the other one for
non-PCI devices.
This is needed because the PCI bus can only address 64MB of RAM, while some
IXP425 boards have 128MB or more, and most of the PCI drivers do not bother
providing the parent dma tag.
- Add a default parent dma tag, similar to what has been done for sparc64.
- Before invalidating the dcache in POSTREAD, save the bits which are in the
same cachelines than our buffers, but not part of it, and restore them after
the invalidation.

bus hanging off from the Fireplane/Safari bus in some USIII machines.
This is part 3/4 of allowing creator(4) to work in these machines.
The little info needed on how to configure the bridge and to work
around the incorrect values contained in the `interrupts' properties
of its children were obtained form OpenSolaris.
The separate bus front-end was inherited from the OpenBSD creator(4),
which at that time had a mainbus(4) (for USI/II machines, which use
an UPA interconnection bus as the nexus) and an upa(4) (for USIII
machines, which use a subordinate/slave UPA bus hanging off from the
Fireplane/Safari interconnection bus) front-end. With FreeBSD and
newbus there is/will be no need to have two separate bus front-ends
for these busses, so we can easily coallapse the shared front-end
and the back-end into a single source file (note that the FreeBSD
creator_upa.c was misnomer anyway; based on what it actually attached
to that should have been creator_nexus.c), actually OpenBSD meanwhile
also has moved to a shared front-end and a single source file. Due
to the low-level console support creator.c also wasn't free from bus
related things before.
While at it, also split sys/sparc64/creator/creator.h into a
sys/dev/fb/creatorreg.h that only contains register macros and move
the structures to the top of sys/dev/fb/creator.c as suggested by
style(9) so creator(4) is no longer scattered over two directories.
- Use OF_decode_addr()/sparc64_fake_bustag() to obtain the bus tags and
handles for the low-level console support instead of hardcoding
support for AFB/FFB hanging off from nexus(4) only. This is part 2/4
of allowing creator(4) to work in USIII machines (which have a UPA
bus hanging off from the Fireplane/Safari bus reflected by the nexus),
which already makes it work as the low-level console there.
- Allocate resources in the bus attach routine regardless of whether
creator(4) is used as for the low-level console and thus the required
bus tags and handles have been already obtained or not so the resources
are marked as taken in the respective RMAN.
- For both obtaining the bus tags and handles for the low-level console
support as well as allocating the corresponding resources in the
regular bus attach routine don't bother to get all for the maximum of
24 register banks but only (for) the two tag/handle pairs required for
providing the video interface for syscons(4) support. If we can't
allocate the rest of them just limit the memory range accessible via
creator_fb_mmap() accordingly.
- Sanity check the memory range spanned by the first and last resources
and the resources in between as far as possible, as the XFree86/Xorg
sunffb(4) expects to be able to access the whole region, even though
the backing resources are actually non-continuous. Limit and check
the memory range accessible via creator_fb_mmap() accordingly.
- Reduce the size of buffers for OFW properties to what they actually
need to hold.
- Rename some tables to creator_<foo> for consistency.
- Also for the sizes in the creator_fb_mmap() mapping table entries use
macros for consistency, add macros for the remaining register banks
for completeness.

operation as it ran out of free descriptors or if there are too many
segments in the first place, call bus_dmamap_unload() in order to
unload the already loaded segments.
For trying to map the defragmented mbuf (chain) in re_encap() this
introduces re_dma_map_desc() setting arg.rl_maxsegs to 0 as a new
failure mode. Previously we just ignored this case, corrupting our
view of the TX ring.
o In re_txeof():
- Don't clear IFF_DRV_OACTIVE unless there are at least 4 free TX
descriptors. Further down the road re_encap() will bail if there
aren't at least 4 free TX descriptors, causing re_start() to
abort and prepend the dequeued mbuf again so it makes no sense
to pretend we could process mbufs again when in fact we won't.
While at it replace this magic 4 with a macro RL_TX_DESC_THLD
throughout this driver.
- Don't cancel the watchdog timeout as soon as there's at least one
free TX descriptor but instead only if all descriptors have been
handled. It's perfectly normal, especially in the DEVICE_POLLING
case, that re_txeof() is called when only a part of the enqueued
TX descriptors have been handled, causing the watchdog to be
disarmed prematurely.
o In re_encap():
- If m_defrag() fails just drop the packet like other NIC drivers
do. This should only happen when there's a mbuf shortage, in which
case it was possible to end up with an IFQ full of packets which
couldn't be processed as they couldn't be defragmented as they
were taking up all the mbufs themselves. This includes adjusting
re_start() to not trying to prepend the mbuf (chain) if re_encap()
has freed it.
- Remove dupe initialization of members of struct rl_dmaload_arg to
values that didn't change since trying to process the fragmented
mbuf chain.
While at it remove an unused member from struct rl_dmaload_arg.
o In re_start() remove a abandoned, banal comment. The corresponding
code was moved to re_attach() some time ago.
With these changes re(4) now survives one day (until stopped) of
hammering out packets here.

more important one (this is the case with 'pmu' and 'lomp'; the
'pmu' node has couple of properties and children while the 'lomp'
one misses most of these). If there's ever a device/dupe pair

- Parse the _CST packages for each cpu and track all the states individually,
on a per-cpu basis.
- Revert to generic FADT/P_BLK based Cx control if the _CST package
is not present on all cpus. In that case, the new driver will
still support per-cpu Cx state handling. The driver will determine the
highest Cx level that can be supported by all the cpus and configure the
available Cx state based on that.
- Fixed the case where multiple cpus in the system share the same
registers for Cx state handling. To do that, added a new flag
parameter to the acpi_PkgGas and acpi_bus_alloc_gas functions that
enable the caller to add the RF_SHAREABLE flag. This flag could also be
useful to other callers (acpi_throttle?) in the tree but this change is
not yet made.
- For Core Duo cpus, both cores seems to be taken out of C3 state when
any one of the cores need to transition out. This broke the short sleep

be re-enabled later differently.

Fixes:
1. Do not assign negative values to variables used to index emu_cards
array. This array was never accessed when index is negative, but
Alexander (netchild@) told me that Coverity does not like it.
After this change emu_cards[0] should never be used to identify
valid sound card.
2. Fix off-by-one errors in interrupt manager. Add more checks there.
3. Fixes to sound buffering code now allows driver to use large playback
buffers.
4. Fix memory allocation bug when multichannel recording is not
enabled.
5. Fix interrupt timeout when recording with low bitrate (8kHz).
Hardware:
1. Add one more known Audigy ZS card to list. Add two cards with
PCI IDs betwen old known cards and new one.
Other changes:
1. Do not use ALL CAPS in messages.
Incomplete code:
1. Automute S/PDIF when S/PDIF signal is lost.
Tested on i386 only, gcc 3.4.6 & gcc41/gcc42 (syntax only).
---snip---
This commits enables a little bit of debugging output when the driver is
loaded as a module. I did a cross-build test for amd64.
The code has some style issues, this will be addressed later.
The multichannel recording part is some work in progress to allow playing
around with it until the generic sound code is better able to handle
multichannel streams.
This is supposed to fix

Bring the linux mmap code more into line with how linux (2.4.x) behaves.
Tested by: Scot Hetzel <swhetzel@gmail.com> on amd64 without PROT_EXEC
Additionally to the i386 version always use PROT_EXEC in the mapping like the
previous version of the amd64 code did. We need to examinate this further to
decide what the right thing to do is. For now this fixes several problems in
the LTP test runs and should behave regarding PROT_EXEC like before.

- Change sched_interact_update() to fix cases where the stored history

fixes a case where sched_priority() could compute a bad value.
- Add a sysctl to disable the global load balancer for experimentation.

- Rename confusing AGP_INTEL_I845_MCHCFG to AGP_INTEL_I845_AGPM.
- Move E7205 and E7505 from i8x5 to i8x0 family. It probably worked
because the actual offset is the same.
In fact, all three families have the bit at the exact same place. Only
differences are name and width of the registers, i.e., NBXCFG (0x50, dword),
RDCR (0x51, byte), AGPM (0x51, byte), MCHCFG (0x50, word) depending on
the family of the chipsets.
sysctl and socket teardown by adding a reference count to the UNIX domain
pcb object and fixing the sysctl that enumerates unpcbs to grab a
reference on each unpcb while it builds the list to copy out to userland.
- Close a race between UNIX domain pcb garbage collection (unp_gc()) and
file descriptor teardown (fdrop()) by adding a new garbage collection
flag FWAIT. unp_gc() sets FWAIT while it walks the message buffers
in a UNIX domain socket looking for nested file descriptor references
and clears the flag when it is finished. fdrop() checks to see if the
flag is set on a file descriptor whose refcount just dropped to 0 and
waits for unp_gc() to clear the flag before completely destroying the
file descriptor.

- Update the priority when we are pulled off of the run queue and when we
are inserted onto the run queue so that it more accurately reflects our
present status. This is important for efficient priority propagation
functioning.
- Move the frequency test into sched_pctcpu_update() so we don't repeat it
each time we'd like to call it.
- Put some temporary work-around code in sched_priority() in case the tick
mechanism produces a bad priority. Eventually this should revert to an
assert again.
