thorpej d5df55112a vm_offset_t -> {paddr_t,vaddr_t}, vm_size_t -> vsize_t 1998-08-14 16:50:00 +00:00
thorpej 97e83f6e0b Change the "vm_offset_t"s to "u_long"s for now; eventually, we can make
them vaddr_t and paddr_t, as appropriate (after scouring the RPB docs
to know which are phys and virt addresses).

default to edge-triggered, just like in the setup.
1998-08-01 19:38:29 +00:00

never becomes untyped.

thorpej f948e430bb Provide a hook for bypassing space accounting, needed to support ISA PnP
for now.
1998-07-31 04:37:02 +00:00
thorpej eb32016a95 Split up using BWX for PCI config and bus access. Default to using BWX for
the former, but not the latter.  Hopefully, this will address some problems
people have been experiencing w/ some devices on Pyxis systems when BWX
is used for bus access.  (If it's not used for PCI config access, we can
get fatal machine checks while probing behind PCI-PCI bridges!!)

thorpej b0b64545e8 Add cs* at isa? port 0x300, wildcard IRQ and memory address, to pull
them from the EEPROM.  Wildcard DRQ to force memory-mode operation; this
value is not available in the EEPROM and must be configured manually.

thorpej 2385ee5eca Provide PMAP_{,UN}MAP_POOLPAGE(). 1998-07-24 20:32:07 +00:00
is 6054d626f9 Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.

On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

ross d58ad29b6c Kill the old extern mchkinfo pointer and prototype cpu_mchkinfo().
This file has been collecting prototypes and other things used in the MD
code...that's bad...because this is exported to the MI kernel.
1998-07-13 19:10:14 +00:00
ross 48257ecec1 Define cpu_mchkinfo() to locate the mchkinfo struct. This is used to fix
the recent bug where Multias around the world have been aborting back to
SRM with no message at all as they tried to attach a TGA or VGA console,
because the old mchkinfo pointer wasn't allocated prior to use.

And contrary to widespread rumour, this bug has nothing to do with my
LCA IDE mod...that worked just fine. "Not guilty."
1998-07-13 19:07:33 +00:00

mjacob 434b3fe82b tentative better fix for allocating the correct number of mchkinfo structs 1998-07-08 16:28:25 +00:00
mjacob ff376fbd03 Doh! Jason caught me being really stupid. There isn't necessarily
a linear 0..N mapping out of alpha_cpu_whami - which is what I was
using to index the new cpu machine check array. This is a quick hack
back to just using the first element while I think of a kinder function
that will do the function (per-platform) of whami->VIRTUAL CPU ID, which
if you think about it, is really necessary anyway.
1998-07-08 05:25:40 +00:00

mjacob 638f0aab7c Clarify comment about what nodes are being 'found' and noted for later
use by an error handler:

 * There can be only one TurboLaser, and we'll overload it
 * with a bitmap of found turbo laser nodes. Note that
 * these are just the actual hard TL node IDS that we
 * discover here, not the virtual IDs that get assigned
 * to CPUs. During TLSB specific error handling we
 * only need to know which actual TLSB slots have boards
 * in them (irrespective of how many CPUs they have).

mjacob 9f1070514c First (prelim placeholder) pass at machine check handler for tlsb 1998-07-08 00:49:06 +00:00
mjacob adf058f0f7 There can only be one TurboLaser node, and now we'll overload
into the integer tlsb_found a bit map of found nodes and export
it to the rest of the kernel. This is so that at machine check
time when we're doing some TLSB/KFTXX error handling we don't
have to attempt a badaddr to look at all TLSB nodes (which will
just be too sad to try...).

mjacob 6f87cdce00 Start of the platform specific (RAWHIDE) machine check handler. This
is not really needed for this platform, except that we might want to
handle PCI errors which get reported through here. In any case, this

this to be based upon DIAGNOSTIC defines.

ross a0f70c580c New platforms: Mikasa and Mikasa/Pinnacle, aka Pinkasa.
Like the 1000A, the AlphaServer 1000 has a daughtercard assembly that
integrates the CPU and core logic, so these can be ev4/apecs or ev5/cia.
New systype, and, sigh, another way of doing interrupts and another
mystery icu.

Kill off some EVCNT_COUNTERS calls, since [A] it has to be rewritten anyway
before it can be useful, and [B] #ifdefs do not belong at every call site,
a common API should be defined and the implementations conditionalized, not
all the calls. Duhh.

thorpej 78d7f07efd Very preliminary support for the Tadpole/DEC AlphaBook. These are basically
AXPpci33 machines + power management and a Cirrus PCI-PCMCIA controller.

1998-06-14 20:09:22 +00:00
cgd 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.

thorpej 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.
1998-06-09 01:04:17 +00:00
thorpej 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.
1998-06-09 00:06:54 +00:00

thorpej 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.

thorpej 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.

- 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"

thorpej a2f214a443 Add fine-grained locking, using a locking protocol modeled after the i386
UVM pmap's locking protocol, written by Chuck Cranor.  Not all of the

drochner 95bdb660ed Simple screen attribute handling for wscons.
The graphics device driver passes a "default attribute" for normal text
