Changed the fifth parameter to register_intr() from u_int mask into
u_int *maskptr in preparation for new features (shared interrupts and
removable devices, eg. for PCMCIA).
of memory to work without running out of kernel VM (and increasing it to
even more than it is now (96MB) is out of the question. Changed bufpages
calculation to allocation a little less bufer cache (16% of mem-2MB instead
of 20%); this is simply a better figure for most systems.
text. Fixed rounding bug that caused the last page of kernel text to be
read/write instead of read-only. This is important now that tmpstk can
crash into it. Removed +4 bias of tmpstk because it screws up ddb's
ability to traceback correctly.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that
. ``doconfig'' can be written
This requires a new version of the `lsdev' program as well (next commit).
explanation. More doc needed, but not hard to do, if you want to.
A big hand to Martin Renters for the netboot program !
Anybody want to compete on who can "make world" in the shortest
amount of time ? I have 127 i486DX2/66 and 5 P60's I can use
now. And 3 times 66 Gb file servers to support it... :->
Anyway, NFS will be standard in the GENERIC kernel now, so that
people can use the bin-tarball to set up shop.
drivers have a chance to change their IRQ before it is checked.
This was implemented in revision 1.21 and broken in revision 1.26.
Drivers that can change their IRQ should probably be configured
with "irq ?".
else has been probed. This feature could go away again, if we can curb the
problem another way.
if_ed.c, syscons.c: Set the above flag. ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)
bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.
isa.c: Probe devices with the above flag set before the rest. Reduce the
number of "conflict" messages per device to one.

Please test the GENERIC-kernel now, if nobody can make it fail, GENERICAH
and GENERICBT has a finite and short life-expectancy...

scheme of things, so I've changed them to be more appropriate. page in/ous
are now associated with the pager that did them. Nuked v_fault as the
only fault of interest that wouldn't be already counted in v_trap is a VM
fault, and this is counted seperately.
2) Implemented most of the remaining counters and corrected the counting of
some that were done wrong. They are all almost correct now...just a few
minor ones left to fix.
"APM" macro.
machdep.c: Made the APM-descriptors unconditional.
Bruce: if these still conflict with your debugger, please put in a reservation
for your debugger. These three desc. can be anywhere, as long as they are
contiguous, so just move them as needed.
pmap.c: tons of unused vars zapped, various other warnings silenced.
trap.c: unused vars zapped.
vm_machdep.c: A wrong argument, which by chance did the right thing, was
corrected.
that and when it does it will be done differently.
2. The kernel now does a frame setup on entry so it ``looks'' like a
real function call. This will be needed by future boot code and
debuggers.
3. Clean up stack offsets to all be in decimal and use %ebp when copying
parameters in from the boot code.
4. Implement version 1 of the uniform boot code passing mechanism with
support for kernelname passing and nfs_diskless structure passing.
5. Document the 3 different ways the kernel is called depending on what code
is calling it.
must #define NFS before including <sys/mount.h> to pick up some of
the definitions needed for struct diskless. Be sure to undef it after this
so you do not effect other code.
This is kinda sick, but it does the job. Problem found by davidg.
2. New detection code so we know what boot code called us.
3. Remove old DISKLESS support code and halt if we are called by that boot
code as it will NOT work with the new nfs_diskless structure.
This is really in preperation for new boot code and new diskless support.
