- we are running on an EV5-family processor,

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.

- Fix the autoconfiguration model; the TCDS children don't attach to
TurboChannel, so don't make it look like they do.

- Recognize the PMAZ-FS (baseboard fast SCSI on DEC 3000s) and the

Give pmap_collect() some substance: when called, a process is being

swapped out, so remove all of the physical mappings the process has
in order to free up the page table pages.

may be called in other situations where the memory situation is desperate,
although it's more likely that the pages will simply be needed again the
next time a process runs.

- The pmap now includes support for ASNs. We no longer need to flush
...
the TLB and I-cache in the SWITCH_CONTEXT macro.
- Right after switching to proc0's newly-created context at startup time,
flush the TLB and I-cache; this is the only place where it's not done
automatically.
- Fix a nasty bug in a critical section of cpu_switch(); change the
pmap_activate -> SWITCH_CONTEXT -> pmap_deactivate sequence to
pmap_deactivate -> pmap_activate -> SWITCH_CONTEXT. This prevents
erroneously marking a pmap inactive if switching to a process that
shares it's address space (and thus its pmap) with the oldproc! Noticed

invalidation algorithm:

Massive cleanup and partial rewrite of the NetBSD/alpha pmap module.

Major change is that page table page management has been completely

Step 1 of the Grand Alpha Pmap Rototill:
...
- Clean up pmap_bootstrap() some, and make a slight change to how the
PROM mappings are saved.
- Give each pmap its own level 1 page table, rather than sharing a global
level 1 page table. This will eventually allow for Very Large user
address spaces.
- Keep a list of all pmaps, so that when kernel level 2 page tables are
allocated, all level 1 tables may be updated.
- Add a couple of functions for allocating and freeing page table pages.
- Add a few comments about ASN allocation.
1998-02-27 03:59:58 +00:00

Several changes related to all pmaps having their own level 1
...
page table:
- Update the current hwpcb pointer in the SWITCH_CONTEXT macro, so that
we know it's always correct.
- Optimize cpu_switch(): if we're switching to ourselves, skip the
actual context swap.
- Clean up some comments and remove some code rendered obsolete by
the fact that address spaces are now selected by switching to a
new level 1 page table.

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).

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...)

Bug fixes and cleanup from Chris Demetriou <cgd@pa.dec.com>:
...
- fix _C_LABEL so that it actually works.
- make __RENAME use _C_LABEL.
- fix __RENAME so that it expects an unquoted argument.
- fix __indr_reference and __warn_references so that they
supply their own final semicolon.
- define __warn_references to nothing if not GNU C (required
by the way it's used).
The __warn_references semicolon change has to be made
so that __warn_references can be defined into nothing.
(A ; all by itself isn't a great idea.) The __indr_reference
change was made for consistency.
