49aea111fb If the platform specified a powerdown hook, and howto has RB_POWERDOWN, 
call the hook.  If the hook fails, print a warning, and just halt (RB_HALT
is implied by RB_POWERDOWN).

bf8523f4e4 - Egads! There are Pyxis "Pass 1" chips that do not have the DMA bug! 
Use the check recommended by the Digital Workstation engineers; look
  for Miata 1 systems (i.e. with Intel SIO).  From Andrew Gallatin.
- Update copyright (Pyxis and BWX).

f251e3372d Don't attempt to map the PCI IDE interrupt at bus 0 device 11 on the 
AlphaPC 164 and AlphaPC 164LX - these are wired to compatibility mode.
 1998-06-05 19:15:41 +00:00

1aa688234e Miata 1 has an Intel SIO at bus 0 device 7 and a CMD PCI IDE at bus 0 
device 4.  Miata 1.5 and Miata 2 have a Cypress at device 7 and PCI IDE
at functions 1 and 2 of the Cypress (like the PC164SX).  These on-board
PCI IDE controllers are wired to compatibility mode, so don't bother
trying to map the interrupt.

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.
