pk 0b1cba4b0b Implement cpu_set_kpc() and use its machinery to by-pass a child out 
of the kernel from cpu_fork().

veego b9f085f78f Restore a local change from our old libg++ to fix a compile warning 1996-03-13 23:07:35 +00:00
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
mark cb6f3bb55c Removed references to the kstack double mapping from the old debug 
shell.
 1996-03-13 21:45:54 +00:00
mark 32f0b6e092 curpcb is declared in pcb.h so don't declare it here. 
removed debug printing when faulting in new page tables for the user
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.
 1996-03-13 21:25:04 +00:00
mark 7045f47891 The kstack pte fields no longer exist so remove them. 1996-03-13 21:22:32 +00:00
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(). 
Arrange for the child process to return to user land via child_return()
on leaving cpuswitch().
Added function cpu_set_kpc().
 1996-03-13 21:16:15 +00:00
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.

christos b92fe0f4c4 Kernel version of longjmp does not take the return value of setjmp as 
an argument. It always returns 1.
 1996-03-13 21:08:09 +00:00
christos b4a31b1fc7 Kernel version of longjmp() does not take the return value of setjmp() as 
an argument. setjmp() always returns 1.
 1996-03-13 21:06:38 +00:00
mark f96ae702d7 Added switchframe structure to describe the stack frame pushed on the 
stack at the beginning of cpuswitch().
 1996-03-13 21:06:34 +00:00
mark c353f32f10 _mcount() can now be declared inline. 1996-03-13 21:04:55 +00:00
mark fb4eacf0a5 Removed comments describing debugging code that has long since gone. 
Added new comments for parts of the undefined vector entry point.

mark 1e97524220 SCSI scanner device added to the list of SCSI devices configured. 1996-03-13 20:57:45 +00:00
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.

jonathan dc6fdf6cdc First commit of Per Fogelstrom's port to the Acer pica r4400/isa machine. 1996-03-13 04:58:04 +00:00
fvdl f5e6df1ed0 Disable invalidating of directory offsets cookies. Should fix one or two 
directory problems.

XXX There is no clean solution to the cookie/cookieverifier validity mess.
    Together with the disabled strict cookie check, this puts us back at
    what v2 did in this case. Slightly better solution possible by
    consequently storing 64bit cookies in other places too.

fvdl 146f96c2ce Make readdirsize default to rsize if rsize is explicitly specified, 
and readdirsize isn't.

scottr b4225290a4 Use 851-specific instructions only #if defined(M68020). 1996-03-12 23:46:32 +00:00
is 905b10d4bc M68060 additional frame formats and bits. Closes PR 1174. 
This shouldn't break anything; I find ... grep ... all the relevant
kernel sources subdirecotry trees I could think of for the defines
that don't use the new FSLW or FPF6 prefix. But in case it does anyway,
tell me immediately.

scottr 6208752b50 Oops; fix typo. 1996-03-12 21:34:57 +00:00
phil 6867e1fda1 Sync with previous changes to Makefiles ... 1996-03-12 21:28:52 +00:00
scottr d504ec531e Add "options M68020" so that 68851-specific code is only compiled when 
we want it (we don't support the 020 without an 851 anyway).  Note that
M68030 no longer implies support for 020+851.

This also allows us to compile with -m68030 iff M68020 isn't specified
in the config file.
