ca49f12fdb Reduce the scope of one #ifdef to avoid duplicating a SYSCTL_INT() macro
and trim another unneeded #ifdef (it was just around a macro that is
already conditionally defined).

8dc0e02023 Be a little more forgiving of lame BIOS writers. If a link device that
doesn't have any actual interrupts is listed in a _PRT entry, only print
a warning rather than panic'ing when we walk the _PRT's to build up count
of entries that reference a given link (the counts are used as weights so
that we can attempt to balance the load across IRQs used by link devices).
Instead, only panic if we attempt to use the _PRT entry to route an
interrupt for a device.

8b6d3fe1b6 Another major fixes and enhancements:
- MPSAFE
    - Fix / reorganize attach routine. Device specific initialization must
      be done after generic bus / DMA setup. At last, Virtual Channels
      (vchan) works as expected.

Note: Recent commit / fix against this driver proves that major enhancements
      on the generic sound layer does indeed help to expose flaw within
      device specific code. There are probably other drivers that need to
      be addressed as well.

5c65ae3a88 New option: NO_FFS_SNAPSHOT. I did this in p4 about the same time
that NetBSD implemented it independently of them (don't know which one
was actually first).  This saves about 24k for those times you don't
need snapshot support (like when running off a ram disk, or in an
embedded environment where size matters).

e730167f16 Remove XXX comments complaining that write(2) on a read-only descriptor
returns EBADF.  That errno is correct and is mandated by POSIX.  It also
goes back to revision 1.1 of our CVS history (i.e. 4.4BSD).

The _fget() function should probably also be upated as it currently returns
EINVAL in that case rather than EBADF.  (It does return EBADF for reads
on a write-only descriptor without any XXX comments oddly enough.)

second values (0-999999000ns with the current interface).
Prior to this change users could create files with values outside
that range.  Moreover, on 32-bit machines tv_usec offsets larger than
4.3s would result in an unnormalized AND wrong timestamp value,
due to overflow.

ab2c368640 Fix a couple of issues with the ibcs2 module event handler. First, return
success instead of EOPNOTSUPP when being loaded.  Secondly, if there are no
ibcs2 processes running when a MOD_UNLOAD request is made, break out to
return success instead of falling through into the default case which
returns EOPNOTSUPP.  With these fixes, I can now kldload and subsequently
kldunload the ibcs2 module.

0d10741255 This signal handling code is worse than a no-op. If a
signal is received during the msleep, the msleep is retried
indefinitely as it just keeps returning ERESTART because of
the pending signal.

Instead, just don't PCATCH - the signal can wait.

ff3ced1270 - Tx side bus_dmamap_load_mbuf_sg(9) support. This reduces bookkeeping
requiried to keep consistent softc state before/after callback function
  invocation and supposed to be sligntly faster than previous one as it
  wouldn't incur callback overhead. With this change callback function
  was gone.
- Decrease TI_MAXTXSEGS to 32 from 128. It seems that most mbuf chain
  length is less than 32 and it would be re-packed with m_defrag(9) if
  its chain length is larger than TI_MAXTXSEGS. This would protect ti(4)
  against possible kernel stack overflow when txsegs[] is put on stack.
  Alternatively, we can embed the txsegs[] into softc. However, that
  would waste memory and make Tx/Rx speration hard when we want to
  sperate Tx/Rx handlers to optimize locking.
- Fix dma map tracking used in Tx path. Previously it used the dma map
  of the last mbuf chain in ti_txeof() which was incorrect as ti(4)
  used dma map of the first mbuf chain when it loads a mbuf chain with
  bus_dmamap_load_mbuf(9). Correct the bug by introducing queues that
  keep track of active/inactive dma maps/mbuf chain.
- Use ti_txcnt to check whether driver need to set watchdog timer instead
  of blidnly clearing the timer in ti_txeof().
- Remove the 3rd arg. of ti_encap(). Since ti(4) now caches the last
  descriptor index(ti_tx_saved_prodidx) used in Tx there is no need to
  pass it as a fuction arg.
- Change data type of producer/consumer index to int from u_int16_t in
  order to remove implicit type conversions in Tx/Rx handlers.
- Check interface queue before getting a mbuf chain to reduce locking
  overhead.
- Check number of available Tx descriptores to be 16 or higher in
  ti_start(). This wouldn't protect Tx descriptor shortage but it would
  reduce number of bus_dmamap_unload(9) calls in ti_encap() when we are
  about to running out of Tx descriptors.
- Command NIC to send packets ony when the driver really has packets
  enqueued. Previously it always set TI_MB_SENDPROD_IDX which would
  command NIC to DMA Tx descriptors into NIC local memory regardless
  of Tx descriptor changes.
