mark 46e6b251f1 Raise the spl level while modifing the keyboard autorepeat and delay 
rates.
Added missing = to test for alphabetic characters so that caps lock
applies to Z as well as A-Y.
 1996-03-13 21:51:32 +00:00
mark a2ff705689 Added code to handle indents in monitor definition files. 1996-03-13 21:47:15 +00:00

shell.

mark 32f0b6e092 curpcb is declared in pcb.h so don't declare it here.

process stack.
 1996-03-13 21:41:41 +00:00
mark ba893940d3 savectx() now justs syncs the pcb, it no longer needs to copy the stack. 
cpuswitch() simplified, now pushes and pulls a switchframe structure
on entry and exit. Added extra comments to indicate the states of
various registers throughout cpuswitch().
Added proc_trampoline function.
 1996-03-13 21:39:10 +00:00
mark 5c857a37ef Use the value returned from initarm() to set the stack pointer before 
calling main().
 1996-03-13 21:34:17 +00:00
mark bbf2aa16b5 Removed kstack references. Updated code that sets up the pcb for proc0 
now that double mapping has gone.
initarm() now returns the address to be loaded into the stack pointer
before calling main() to kick things off.
 1996-03-13 21:32:39 +00:00
mark d253d345a2 Since kernel stack double mapping no longer exists there is no 
point in trying to perform a postmortem on it following an panic.
 1996-03-13 21:26:52 +00:00
mark 52f490ccf6 No longer need to allocate hooks for kernel stack double mapping during 
pmap bootstrapping.

mark caf9dd3edc Removed external declaration of kstack. No longer relevant now kstack 
double mapping has been removed.
No longer need to fixup the trap frame address to take double mapping
into consideration.
 1996-03-13 21:21:00 +00:00
mark 043ef25c23 Remove cpu_set_init_frame macro. This is no longer needed now 
cpu_set_kpc() has been implemented.
 1996-03-13 21:18:06 +00:00
mark f9f45be67c Removed all the double mapping code from cpu_fork().

mark 8fbba52c87 Removed option __FORK_BRAINDAMAGE at last. 1996-03-13 21:10:43 +00:00
mark ffa6eab259 Removed the kstack pte fields. These are no longer needed as the kernel 
stack is no longer double mapped.
 1996-03-13 21:08:36 +00:00
mark f96ae702d7 Added switchframe structure to describe the stack frame pushed on the

mark f6c46bc20c Added hooks for the SCSI scanner device driver. 1996-03-13 20:55:21 +00:00
mark d389b21913 Added boot time override for the memory test during probing. This 
memory test apparently causes hangups on some etherH interfaces.
Until this can be debugged with an offending interface the memory
test can be bypassed.
 1996-03-13 20:52:35 +00:00

UND32 mode stack pointer during a context save.
 1996-03-09 17:15:46 +00:00
mark 30bb966970 Cleaned up the boot() function. Removed some of the garbage, 
rewritten parts and made sure it uses cngetc().
Don't try and syn the discs or unmount filesystems if boot() gets
called while still cold.
 1996-03-08 21:37:01 +00:00
mark 657b336f18 Restructured management of L1 page tables. Added support for

 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

 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.

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

 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.
