1fbd0b3749 GC the unused `physadr' type, which was not able to hold a complete physical 
address on 2 architectures anyhow.  Also, move the definition of the `label_t'
type inside _KERNEL protection, since it is specific to the in-kernel
setjmp()/longjmp() implementations.

651b44e211 Rework the way kernel include files are installed. In the new method, 
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

ff16cd85c0 In pmap_enter(): if old PTE was not valid, we don't need to sync 
the I-stream, for the same reason we don't need to invalidate the TLB.

c0c2cb0f9a Garbage-collect the old PMAPSTATS stuff; it didn't compile, and should 
just be redone from scratch.  Get it out of the way now to make it easier
to restructure a few things.

afc9b7c59b Significantly reduce the number of I-stream synchronizations by really 
decoupling this operation from TLB invalidations (e.g. pull I-stream
syncs out of loops, executing them only once, etc.).

680a3d77f4 Add isa_dma{freeze,thaw}(), used to temporarily stop and then restart 
all ISA DMA.  Needed by e.g. the SmartCard reader for Sharks.

53394a1d41 Change the ISA DMA API to take an isa_chipset_tag_t rather than 
a struct device * corresponding to the ISA bus device.  The ISA DMA
controller driver functions have been renamed and now take a struct
isa_dma_state *, and are called indirectly by machine-dependent code
which provides the DMA state.

These changes allow e.g. `ofisa' (the OpenFirmware configuration
mechanism for the ISA bus, used by e.g. Sharks) to use the MI ISA
DMA controller code.

f5cd6a7736 Add debugging support to the bus_space macros. If BUS_SPACE_DEBUG (or DEBUG) 
is defined, the bus_space macros will check to ensure that the bus address
and the target buffer (if applicable) are aligned properly for the size
of the type being used.  If they are not, a message will be displayed on
the console.

Strict alignment is required by the Alpha architecture, and a trap will
occur of unaligned access is performed.  These changes will aid debugging
of broken device drivers.

0890af5ca8 Only disable an interrupt line after MAXSTRAYs if there is no handler 
attached; we get stray interrupts on PCI devices sometimes, for some
unknown reason.  (Similar problem exists on the 164SX, which also has
a Pyxis.)

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.

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.
