thorpej 99cc8482d1 Change the last argument of bus_dmamap_sync() from bus_dmasync_op_t to int,

a single call.  Dissallow mixing of PRE and POST operations.
1998-02-04 01:57:27 +00:00

ross d0cce6d144 Take Jason's most excellent advice on platform.model. 1998-01-31 10:55:42 +00:00
ross 1e62e0ffd9 Remove the #include of rpb.h from clock.c and set hz from the hwrpb
in alpha_init() instead of from a hardwired 1024 in cpu_initclocks().
1998-01-31 10:32:47 +00:00
cgd 58fb6574f9 valloclim() was unused; kill it. #undef valloc() at the end of
allocsys().
1998-01-31 02:20:44 +00:00
ross 6270ed1711 Add the A12 fast ethernet controller, an if_de.c hacked (prior to
bus_dma's appearance in the tree) to support sram bounce buffers.
When a busified if_de.c appears, this module can join awd.c at the
end of that long walk on a short pier.
1998-01-31 01:43:40 +00:00
ross 3a83745247 In some hp300-derived pmaps, in pmap_page_protect(), don't walk off the
end of the list of physical->virtual entires into NULL space if the last
entry is (mysteriously) wired in the pmap. Add a DEBUG printf on alpha.
1998-01-31 01:32:55 +00:00

ross f2d2b6bf68 defopt for AVALON_A12 and specifiers for all the platform modules. 1998-01-29 22:23:06 +00:00
ross 18beceb2f9 Recognize Avalon A12 cputype code. 1998-01-29 22:20:15 +00:00
ross 43a3471986 While here in alpha/stand, add a technically required imb coherency op
just before transferring to the kernel entry point.
1998-01-29 22:13:25 +00:00
ross c1972a428c Avoid VMS palcode ops by using a different technique for cpu_number(),
and don't execute the VMS->OSF palcode switch if the OSF palcode
is already running...which will be the case if the console is not
the venerable SRM.
1998-01-29 22:09:37 +00:00
ross 8430acf1e7 Add a12 platform support. The A12 is a scalable, distributed memory parallel
processor.
1998-01-29 21:46:33 +00:00
ross 12f93343cd Add basic platform support for NetBSD on the Avalon A12. I'm running this
CVS commit on one right now...
1998-01-29 21:42:50 +00:00
ross 683fada0e3 Clean up duplicated code sequences and add an imb (a coherency operation)
whenever the console code is mapped and unmapped.
1998-01-29 21:11:58 +00:00
ross 0c4d28f49e Fix an alpha-specific page daemon wedge...the new pmap_clear_reference()
may be faster, but it was supposed to _clear_ PMAP_ATTR_REF, not _set_ it.
1998-01-29 05:44:57 +00:00
thorpej 2538ed1062 Use offsetof() from libkern.h 1998-01-28 02:23:04 +00:00

mycroft 15ae963bea When dumping, print out the device number as major,minor. 1998-01-24 16:46:23 +00:00
thorpej cacd48c0d6 Print the correct error number if nfs_mount() fails. From Chris Demetriou. 1998-01-23 19:13:28 +00:00
thorpej 9c3ef8899b Don't conditionally define the sgmap_log_entry structure, and turn off
SGMAP logging by default.
1998-01-21 22:36:10 +00:00
thorpej 3d9cd8a05a Extent names are const. 1998-01-21 22:34:38 +00:00
thorpej 12809e3434 If mapping only one segment of DMA memory into KVA space, use K0SEG. 1998-01-19 03:12:20 +00:00
thorpej c6d1f2e018 G/c LANCE DMA allocation goop. 1998-01-19 02:57:28 +00:00
thorpej e5e8573d5c Allocate the LANCE DMA area and set it up here. This is still not
optimal (really should be done further down the food chain), but we
can't really do that in a nice way right now, and this is much better
than what we had before (which was to steal memory pages before the
VM system was bootstrapped).
1998-01-19 02:56:05 +00:00
thorpej bf92ae27ef Pass a pointer to the "get this slot's DMA tag" function pointer to
the tc instance just like we do with the interrupt functions.
1998-01-19 02:54:24 +00:00
thorpej 806e953f2c Get the per-slot DMA tag a bit differently. 1998-01-19 02:53:29 +00:00
thorpej 70da5cdba9 G/c an unused function pointer. 1998-01-19 02:53:03 +00:00
drochner 32d94859ea adapt to changed <dev/ic/i8042reg.h> 1998-01-18 14:45:10 +00:00
thorpej e62d894d7a Implement a prefetch spill page for SGMAP DMA. This works around a slight
annoyance on systems that prefetch the next page during memory -> device
DMA if the DMA comes within a certain distance of the end of the current
page.  This could cause machine checks since the PTE after the last page
would not have the valid bit set.

(I'm not going to complain about this slight kludge too much, since prefetch
makes DMA much faster...)
1998-01-18 00:05:33 +00:00
thorpej 8df306036a Initialize s/g DMA registers in the same order as the CIA chipset's:
(1) window base
	(2) window mask
	(3) translation base
1998-01-17 22:46:55 +00:00
thorpej 3366b987d0 Put SGMAP-related stuff in the DMA map structure directly, rather than
indirecting through a pointer.
1998-01-17 21:53:52 +00:00
thorpej 63db8935a6 Fix initialization of DMA window 0:
- Make sure the page table is aligned to at least 32k.
- Don't consider the MEMCS signal when checking for a window hit.
1998-01-17 03:43:59 +00:00
thorpej 9554b5a243 Update for "minptalign" argument to alpha_sgmap_init(). 1998-01-17 03:40:32 +00:00
thorpej 399f3639cf Don't assume that we'll be using direct-mapped DMA for PCI. 1998-01-17 03:39:51 +00:00
