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().

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.

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.

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.

8430acf1e7 Add a12 platform support. The A12 is a scalable, distributed memory parallel 
processor.

12f93343cd Add basic platform support for NetBSD on the Avalon A12. I'm running this 
CVS commit on one right now...

683fada0e3 Clean up duplicated code sequences and add an imb (a coherency operation) 
whenever the console code is mapped and unmapped.

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.

c6d1f2e018 G/c LANCE DMA allocation goop. 1998-01-19 02:57:28 +00:00

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).

bf92ae27ef Pass a pointer to the "get this slot's DMA tag" function pointer to

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...)

8df306036a Initialize s/g DMA registers in the same order as the CIA chipset's: 
(1) window base

3366b987d0 Put SGMAP-related stuff in the DMA map structure directly, rather than 
indirecting through a pointer.

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.

361179df26 Make debugging decisions at run-time, and place a handy DDB breakpoint 
after a transfer has been mapped in the page table.

2981fec2f0 Allow specification of a minimum page table alignment to alpha_sgmap_init(). 
This is to work around an apparent hardware bug in some 2117x chipsets
where the page table must be aligned to at least 32k.
