mark 657b336f18 Restructured management of L1 page tables. Added support for 
detaching an L1 page table from a process that is swapped out.
 1996-03-08 21:21:47 +00:00
mark 713cab03b9 Updated comments, removed a lot of dead code and other old debugging 
functions.
 1996-03-08 21:08:39 +00:00
mark 700050b193 Added support for freeing level 1 page tables when cpu_swapout() is 
called.
Added support for reallocating level 1 page tables when cpu_swapin() is
called.
 1996-03-08 20:58:40 +00:00
mark a3aaf2a2c0 Removed old (and commented out) diagnostic code from 
undefinedinstruction() that verified the function was not
called in UND32 mode. We now always expect undefinedinstruction()
to be called in UND32 mode.
 1996-03-08 20:54:25 +00:00
mark 7c5f0f1407 Removed declarations of external variables no used in the file. 1996-03-08 20:49:47 +00:00
mark e03778a035 Updated irq names, replaced reserved irq 1 with irq softclock. 1996-03-08 20:44:13 +00:00
mark c5e6adffe0 Removed dead wood from swi and undefined vector entry point code. 1996-03-08 20:37:59 +00:00
mark d2a9bb0b96 Config files updated to specify interrupt numbers for wd, fd, com and 
lpt drivers.
 1996-03-08 20:35:28 +00:00
mark ea1eb0f702 Added calls to spl_setmasks(). 
Remove the irq_setmasks() routine. This was coded in assembly months ago
and this C version is now out of date.
Added code for delivering IRQ_SOFTCLOCK.
 1996-03-08 20:35:08 +00:00
cgd 8d459740a7 kill some 'notyet's so that <machine/bus.h> is used 1996-03-08 20:26:59 +00:00
cgd 91d7642d30 implement bus_mem_map() and bus_mem_unmap() functions. 1996-03-08 20:19:48 +00:00
cgd 0b56afadf3 make this idempotent. bus.h needs to include it, and other things which 
may include something that includes bus.h may include it as well.
 1996-03-08 20:15:23 +00:00
mark 2a40f64a5d Fixed the formatting of the debug output. 1996-03-08 20:14:48 +00:00
cgd 6826c7bf48 bus memory and I/O space access functions/macros, to be used by 
machine-independent code for more sane access to bus resources.
New functions will be added to this set, in the future, as appropriate,
but this is a good starting set.  Defines:
	bus_{io,mem}_{map,unmap}
	bus_{io,mem}_{read,write}_{1,2,4,8}
functions, and several types to go with them.
 1996-03-08 20:11:23 +00:00
mark 95b04c378b Updated for new spl macros. 
Added missing #ifdef DIAGNOSTIC round the checks in setrunqueue().
Remove dead commented out code fragments.
Removed checksumming of kernel stack during context switches.
 1996-03-08 20:03:12 +00:00
mark 7a9dc6a41a Inclusion of machine/psl.h is no longer dependant on _LOCORE being not 
defined.
 1996-03-08 19:08:28 +00:00
mark 5254468ebb setjmp() and longjmp() now use a buffer whose size is that of label_t 
rather than one that was 44 bytes bigger. No wonder DDB was not working
properly.
 1996-03-08 19:03:11 +00:00
mark 33405882d3 The microtime() function now works fine all the time. 
Removed some old commented out code.
 1996-03-08 18:57:41 +00:00
mark 868a5d45f6 Updated diagnostic code regarding the changes in the splxxx() functions 
and determining the current spl level.
 1996-03-08 18:54:55 +00:00
mark 85d00ef7b5 Added a couple of miscellaneous spl functions e.g. dumping spl 
masks.
 1996-03-08 18:41:52 +00:00
mark 2d5be5faa9 Commit of the new assembly spl functions splx(), raisespl() and 
lowerspl() to go with the new spl macros in psl.h
 1996-03-08 18:03:15 +00:00
mark 90a4655005 Added files for the generic sbic driver. (sbic.c) 
Added files for the asc driver (asc.c)
Added assembly file for spl functions (spl.S)
Added machine dependant debugger commands file. (db_machdep.c)
 1996-03-08 18:02:23 +00:00
mark 409de3efcc spl.c is no longer needed. Most of its functions have been replaced 
with macros in psl.h. The spl functions splx() raisespl() and lowerspl()
are now coded in assembly.
 1996-03-08 17:50:46 +00:00
mark 9deb24c84d Corrected spelling mistakes in comments. 1996-03-08 17:11:13 +00:00
mark 57fbb17f0e Replaced the splxxx() functions prototypes with macros. 
Added prototypes for two new functions raisespl() and lowerspl().
Added definititions of the various spl levels.
 1996-03-08 16:35:17 +00:00
mark 50b27325dd Removed all the early (and now redundant) keyboard polling and interrupt 
buffer. The new polling function for cngetc() works a lot better and
is stable.
 1996-03-08 16:28:54 +00:00
mark 7b3a5bb292 Fixed prototype declaration of shell(). 1996-03-08 16:25:07 +00:00
mark 1014c385d8 Added NetBSD tag. 1996-03-08 16:24:51 +00:00
mark 00af8622e0 Added NetBSD tag. Reformatted source kernel in line with the style 
guide.

mark 095bb565ba Files for the new Acorn SCSI driver that uses the generic SBIC driver 
code. This is a much better version that does not trash your HD.
 1996-03-07 23:54:28 +00:00
mark 3506c48c2a opps forgot to remove this as well. Part of the old and BUGGED Acorn 
SCSI driver.
 1996-03-07 23:50:33 +00:00
mark 169a40e0cf These files represent the old and BUGGED Acorn SCSI driver. 
They are replaced with a new Acorn SCSI driver based on the SBIC
generic SCSI code.
 1996-03-07 23:45:24 +00:00
ragge 6e51b1e47e Support for VAX 8600/8650 added. Works with lots of Unibus adapters, 
and will probably work with Massbus adapters as well. (Not tested,
but it's the same code as for 11/780). Ubareset's may cause crashes
on 8600 also like 11/780, but they are more uncommon. No support
for console RL02 yet, but it's likely to come.
