7ee4af11a7
Change active_pmap() to use the CPU mask (XXX and check for kernel pmap

as well, until some other changes are made). Nuke active_user_pmap(),

as make some DIAGNOSTIC consistency checks).

605472f676
Optimize out a TLB invalidation in a common case of pmap_enter(): if
...
the PTE was previously invalid, no TLB invalidation is necessary because:
(1) when a PTE is invalidated, its entry is flushed from the
TLB
(2) the PALcode won't install an invalid PTE into the TLB.

Don't call pmap_deactivate() if we jumped into the middle of cpu_switch()

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

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.

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

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

would not have the valid bit set.

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.

on EV56 and later processors that have the "amask BWX" bit clear. These

PCI chipsets.

Support for the upcoming NetBSD/Amiga Hypercom driver family:
...
* support chip clocks != COM_FREQ, by introducing sc_frequency (for the
mainline code) and adding a frequency parameter right after the rate
parameter to comcnattach() and com_kgdb_attach().
- Make com_isa and com_multi initialize sc_frequency to COM_FREQ.
- Make i386/machdep.c and alpha/dec_xxx.c call com*attach() with the freq.
parameter.
* supio_attach_args get two more fields: a sc_ipl and a sc_arg, both ints.
- com_supio uses the first for interupt establishment (all childs will, as
soon as they exist) and the 2nd for sc_frequency.
- drsupio passes sc_ipl alway as 5, and for the "com"s, sc_arg as 16*115200
- hyper will pass sc_ipl as 6, and sc_arg as 16 * 460800

From page 6-9 of "Alpha AXP Architecture Reference Manual, Second Edition":
...
An IMB intruction must be executed after software or I/O devices
write into the instruction stream or modify the instruction
stream virtual address mapping, and before the new value is
fetched as an instruction.
We were missing calls to IMB after mappings were changed, which caused
systems with large I-caches (e.g. my AlphaStation 500) to fail miserably
when mapping in new pages of program text, or when context switching
(I couldn't even get the shell from init!).

In addition to MAS_ABT, check TAR_ABT when doing configuration space
...
reads. This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts. Reported by Matthias Drochner.

Apparently, new AlphaStation 500/600 firmware has the same problem with
...
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.
This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either. Thanks to Matt Jacob for pointing out this goof.

Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on
...
such code for Mach 3's Alpha port. Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me. Works, but is still
a little rough around the edges. Known problems:
- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times. (Alpha doesn't have hardware
support for single-stepping, and I'm not entirely convinced the
MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.
