d807a231a2 Add uaudio -- a USB audio device driver.
This driver actually works slightly better on -stable than on -current
(the system locks on detach on -current), so it should be MFC'd somewhat
sooner.

This driver currently points out a difficulty in the sound device framework.
The PCM unregister routine is allowed to refuse the detach if the device is
in use. In the case of a USB device, however, this unregistration is much more
mandatory in nature, since the device is *actually* gone when this call is
made. The sound subsystem really should not refuse an unregistration and
should take its own steps to reject further I/O. As a result, if you detach
a USB sound device while it is in use, you can expect a panic shortly
thereafter.

This device cannot currently record audio. Some routines are unwritten as
of yet in uaudio.c to support recording.

This device hangs my -current box on detach. I don't know why. This does
not happen on my -stable machine.

914ecdc8ea Work around some nasty bugs on the [beta] Itanium2's E1000 UNDI driver.
Bug#1: The GetStatus() function returns radically different pointers that
do not match any packets we transmitted.  I think it might be pointing to
a copy of the packet or something.  Since we do not transmit more than
one packet at a time, just wait for "anything".

Bug#2: The Receive() function takes a pointer and a length.  However, it
either ignores the length or otherwise does bad things and writes outside
of ptr[0] through ptr[len-1].  This is bad and causes massive stack
corruption for us since we are receiving packets into small buffers on
the stack.  Instead, Receive() into a large enough buffer and bcopy the
data to the requested area.

3ebc124838 Infrastructure tweaks to allow having both an Elf32 and an Elf64 executable
handler in the kernel at the same time.  Also, allow for the
exec_new_vmspace() code to build a different sized vmspace depending on
the executable environment.  This is a big help for execing i386 binaries
on ia64.   The ELF exec code grows the ability to map partial pages when
there is a page size difference, eg: emulating 4K pages on 8K or 16K
hardware pages.

Flesh out the i386 emulation support for ia64.  At this point, the only
binary that I know of that fails is cvsup, because the cvsup runtime
tries to execute code in pages not marked executable.

7aca6291e3 Add support to UFS2 to provide storage for extended attributes.
As this code is not actually used by any of the existing
interfaces, it seems unlikely to break anything (famous
last words).

The internal kernel interface to manipulate these attributes
is invoked using two new IO_ flags: IO_NORMAL and IO_EXT.
These flags may be specified in the ioflags word of VOP_READ,
VOP_WRITE, and VOP_TRUNCATE. Specifying IO_NORMAL means that
you want to do I/O to the normal data part of the file and
IO_EXT means that you want to do I/O to the extended attributes
part of the file. IO_NORMAL and IO_EXT are mutually exclusive
for VOP_READ and VOP_WRITE, but may be specified individually
or together in the case of VOP_TRUNCATE. For example, when
removing a file, VOP_TRUNCATE is called with both IO_NORMAL
and IO_EXT set. For backward compatibility, if neither IO_NORMAL
nor IO_EXT is set, then IO_NORMAL is assumed.

Note that the BA_ and IO_ flags have been `merged' so that they
may both be used in the same flags word. This merger is possible
by assigning the IO_ flags to the low sixteen bits and the BA_
flags the high sixteen bits. This works because the high sixteen
bits of the IO_ word is reserved for read-ahead and help with
write clustering so will never be used for flags. This merge
lets us get away from code of the form:

        if (ioflags & IO_SYNC)
                flags |= BA_SYNC;

For the future, I have considered adding a new field to the
vattr structure, va_extsize. This addition could then be
exported through the stat structure to allow applications to
find out the size of the extended attribute storage and also
would provide a more standard interface for truncating them
(via VOP_SETATTR rather than VOP_TRUNCATE).

I am also contemplating adding a pathconf parameter (for
concreteness, lets call it _PC_MAX_EXTSIZE) which would
let an application determine the maximum size of the extended
atribute storage.

701bec5a38 Introduce two new sysctl's:
net.inet.tcp.rexmit_min (default 3 ticks equiv)

    This sysctl is the retransmit timer RTO minimum,
    specified in milliseconds.  This value is
    designed for algorithmic stability only.

net.inet.tcp.rexmit_slop (default 200ms)

    This sysctl is the retransmit timer RTO slop
    which is added to every retransmit timeout and
    is designed to handle protocol stack overheads
    and delayed ack issues.

Note that the *original* code applied a 1-second
RTO minimum but never applied real slop to the RTO
calculation, so any RTO calculation over one second
would have no slop and thus not account for
protocol stack overheads (TCP timestamps are not
a measure of protocol turnaround!).  Essentially,
the original code made the RTO calculation almost
completely irrelevant.

Please note that the 200ms slop is debateable.
This commit is not meant to be a line in the sand,
and if the community winds up deciding that increasing
it is the correct solution then it's easy to do.
Note that larger values will destroy performance
on lossy networks while smaller values may result in
a greater number of unnecessary retransmits.

Also synchronize ip_dummynet.c with the version in RELENG_4 to
ease MFC's.

1dc510f6ca Better verbage on hw.pcic sysctls, delete now obsolete comment 2002-07-17 06:29:35 +00:00

d9619df632 o Remove workaround that I put in to mask the BadVcc problem.
o Add preliminary support for Cirrus Logic CL-PD6729 using PCI
  interrupts.  To use it you you need to set hw.pcic.pd6729_intr_path
  to 2.  This is allow us to still default to ISA intrrupt path for
  this part (which is found much more often in laptops using ISA IRQs).
  But some PCI cards have this part on them and this should allow them
  to be used.  It is untested on PCI, but it seems to not break the ISA
  case.
o Better sysctl descriptions (I hope).

79d9b7534a Be more conservative about the address ranges we assign. Some
machines don't like the more liberal default, so be more conservative
about what we do by default.

d4616eacb1 Qualify comment on machdep.cpu_idle_hlt. Turning this on on a SMP
machine will result in approximately a 4.2% loss of performance (buildworld)
and approximately a 5% reduction in power consumption (when idle).  Add XXX
note on how to really make hlt work (send an IPI to wakeup HLTed cpus on
a thread-schedule event?  Generate an interrupt somehow?).

c1bb793bbb Eliminate the need for pccard_common.c by moving the function inline
in the .h file.  Make it static __inline to make sure that it doesn't
wind up defined in any files.

Also, fix a typo that said null_do_attach instead of null_do_probe.

8034890757 - Use more correct values to initialize the AGP controller during setup.
The value we use is still questionable for 440BX chipsets.
- When flushing the TLB just toggle the bit in question instead of writing
  a magic value that could trash other unrelated bits.

3d3f20cbe6 Preallocate a struct file as the first thing in falloc() before we lock
the filelist_lock and check nfiles.  This closes a race where we had to
unlock the filedesc to re-lock the filelist_lock.
