cgd 94907fa254 adjust to deal with expression support for optional file specs 1996-03-17 13:21:09 +00:00
thorpej 5c67e5fad9 New device attachment scheme:
- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

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 ba893940d3 savectx() now justs syncs the pcb, it no longer needs to copy the stack.

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.

into consideration.
1996-03-13 21:21:00 +00:00
mark 043ef25c23 Remove cpu_set_init_frame macro. This is no longer needed now

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
stack at the beginning of cpuswitch().

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

mark 30bb966970 Cleaned up the boot() function. Removed some of the garbage,

called while still cold.
1996-03-08 21:37:01 +00:00

mark a3aaf2a2c0 Removed old (and commented out) diagnostic code from
undefinedinstruction() that verified the function was not

to be called in UND32 mode.
1996-03-08 20:54:25 +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
