9c3ef8899b Don't conditionally define the sgmap_log_entry structure, and turn off 
SGMAP logging by default.

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).

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.

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
	(2) window mask

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.

1256fac296 Rearrange alpha_init() somewhat, setting the page size much earlier, and 
keeping track of where the kernel lives in K0SEG.  Place early data
structure allocation into an allocsys() function, like other ports, so
that it can be used to first calculate the amount of memory needed
for those data structures.

e47378c640 - pmap_collect_pv() is broken; #ifdef it out (it's not currently ever 
called anyway, but now at least the reason is documented).
- rearrange a few things to make it easier to add support for non-contigous
  physical memory.
