3249813e11 For whatever reason, the firmware seems to enable PCI loopback mode if it 
also enables BWX.  Make sure it's enabled if we have an old, buggy firmware
rev.

d4d49905dd Add support for using BWX for PCI config space and PCI i/o and mem space 
on the ALCOR2 and Pyxis.  BWX is enabled iff:
- It hasn't been disabled by the user (patch `cia_use_bwx' or build cia.o
  with the option "CIA_USE_BWX=0"),
- it's enabled in CIA_CSR_CNFG,
- we are running on an EV5-family processor,
- BWX is in the processor's capabilities mask.

616125f8d1 Deal with a hardware bug in Pass 1 and Pass 2 Pyxis chips. Basically, 
the scatter/gather TLB cannot be invalidated on these chips.  So, to
work around this, we configure the otherwise unsed DMA Window 2 as a
2M SGMAP window at 128M, point all of its page table entries at the
DMA spill page, and, when the TLB is to be invalidated, put the PCI bus
into loopback mode, and create a target hit on Window 2 every 64k for
the number of TLB entries (plus a few ... it seems to not work unless
we read a few extra times), forcing out old TLB entries to make room for
the new, dummy target hits.

d94f02f9fd Ok, now we _REALLY_ have Pyxis recognition correct. There are two systypes 
that can have Pyxis: EB164 (AlphaPC164LX and AlphaPC164SX) and DEC_550 (Miata),
and these systypes/variations _always_ have Pyxis.

d6041754c2 Allow the DMA tag to specify a boundary contraint. If the device has a 
more strict boundary, the map will use it, otherwise the map will inherit
the tag's, unless the tag's constraint is 0 (no boundary constraint).

d3ead78027 Several changes to the TurboChannel Dual SCSI driver: 
- Fix the autoconfiguration model; the TCDS children don't attach to
  TurboChannel, so don't make it look like they do.
- Make the driver use bus_space (not bus_dma yet; soon)
- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the
  PMAZB-AA (TCDS option card) and PMAZC-AA (TCDS fast SCSI option card).
- Rearrange it a bit, so that it can eventually be made into an "MI"
  TurboChannel driver (i.e. work on DECstations).

UVM pmap's locking protocol, written by Chuck Cranor.  Not all of the

under moderate loads with LOCKDEBUG (all locking operations are no-ops
unless LOCKDEBUG is turned on).

This is by no means complete... there are still some possible snares
to take a look at.

95bdb660ed Simple screen attribute handling for wscons. 
The graphics device driver passes a "default attribute" for normal text
output to the wscons framework. If the emulation module needs more
attributes (for different "renditions") it can allocate them via a
callback.
For now, only the "sun" emulation makes use of it.

0624060713 Rework PCI interrupt mapping on the EB164 systype. Rather than computing 
interrupt routing directly, use the interrupt routing information provided
in the PCI "line" register.  The previous scheme did not work properly on
AlphaPC 164SXs.  Also, be silent about the fact that 0/8/x does not
have its interrupt mapped; this is to be expected on the 164SX (this is
the Cypress PCI-ISA bridge, which has IDE wired to compat mode on functions
1 and 2; the 164SX does _not_ have PCI IDE on device 11 like other AlphaPCs).
