f5535d79ca Provide the ISA chipset tag. 1998-07-08 04:59:02 +00:00
thorpej
8eeb7eaad0 Implement an ISA bus_dma back-end for NetBSD/arm32. Tested only on the 
Shark, but should work for other ISA-"enabled" arm32 systems, as well.

696858d5f9 Nuke these; we use the MI ISA DMA code now. 1998-07-08 04:57:13 +00:00
thorpej
98b07e4b07 Provide an ISA chipset tag via isa_attach_hook(). G/c home-grown 
ISA DMA code, in favor of the MI code.

b51b6b7c04 Lift-and-tweak from the i386 port (near-complete rewrite), providing 
the ISA DMA stuff expected by machine-independent code.

f7e400a7ab Use the machine-independent ISA DMA code. 
XXX We use COHERENT for now; need to deal with sync'ing DMA maps being
XXX used by the isadma driver.

thorpej
a177e7aedc Rearrange this a little so we can use MI ISA DMA code. XXX Should just 
pull in files.isa, but Not Right Now, apparently.

Add the sound blaster driver here (XXX see above), and build the
arm32 bus_dma back-end.

8e03657b43 Define two free lists: default, and one to protect ISA DMA-safe memory. 1998-07-08 04:49:21 +00:00
thorpej
d7d001fe70 Allow platform-specific code to define DMA-safe memory ranges for ISA. 
If pages being loaded into the VM system intersect with any of these
ranges, the intersecting pages will be placed on a lower-priority
free list to protect them.

d47ea67c1f Define one page free list, and put all pages on it. 1998-07-08 04:43:18 +00:00
thorpej
6fa49323d7 Put VMEbus RAM on a lower priority free list, since it's much slower (because 
the MVME-147 doesn't cache access to any VMEbus space).

6fb9a8addf Define one page free list, and put all pages on it. 1998-07-08 04:39:34 +00:00
thorpej
1bd007d54b Define 2 free lists: a default, and a "first16", which is where the first 
16M of RAM goes (in an effort to protect ISA DMA-safe memory).
 1998-07-08 04:38:33 +00:00
thorpej
26287d01ec Put the first 16M of RAM onto the "first16" free list, and everthing 
else onto the default free list.
 1998-07-08 04:37:43 +00:00
thorpej
a5dd574b12 Attempt to pull buffer cache pages out of the "first16" free list, in 
an effort to avoid bouncing file system buffers (it's not clear how much
of a win this is, and it'll be pointless w/ a unified buffer cache, but
what the heck).

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).

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...).

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
prints out more info than is usual. Will probably need to detune
this to be based upon DIAGNOSTIC defines.
