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

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

invalidation algorithm:

Massive cleanup and partial rewrite of the NetBSD/alpha pmap module.
...
Major change is that page table page management has been completely
rewritten. Page tables are now accessed via K0SEG (no more KVA space
wasted on user page tables), and a much larger user address space is
supported.
Many thanks to Chris Demetriou and Ross Harvey for helpful insight and
debugging assistance.

Revamp pv_table management:
...
- Make pv_table an array of struct pv_head's, which contain LIST_HEADs
for the pv_entry's, as well as page attributes (mod, ref, ptpage).
- Use <sys/queue.h> to manipulate pv_entry lists.
- Fix several obvious bugs in pmap_collect_pv().
- Use K0SEG to access pv_page's.

Changes necessitated by the fact that all pmaps have their own level 1

c4e7c88520
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
5d56ce57ba
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.

Clean up kernel initialization. Use the bootinfo structure (or innate

init code carefully re: when it can print stuff out, when it can expect
the firmware to stop working, etc. Be more careful about using the PROM
console and other PROM facilities, and hint that in the future all use
of firmware/boot program callbacks by the kernel should go away (since
the world may not be mapped the way the firmware/boot program wants!).
