jdolecek 2fa1ccfa6e bootpath_build(): implement slighly more clever algorith to find boot 
flags in the bootpath: only treat the rest as boot flags if the '-'
follows whitespace (space or tab)

This should fix the "boot disk4 netbsd-20001004-RFHS8036" lossage
Hubert Feyer pointed out in private e-mail.

eeh 6638fc7c06 Fix interrupt lossage problem and some cosmetic changes. 2000-10-04 22:18:25 +00:00
pk d26132e2be cpu_initialize: global registers aren't preserved across calls to 
prom_printf(), so replace %g3 with %l7 (which isn't used despite
the `usage' comment).

Also, clean up white-space turds.

0x0000000001000000 -- 0x00000000f0000000, below the PROM where the
PROM thinks we should be.

eeh d21456569e Fix INTR_SETUP() to properly distinguish kernel and user addresses. 
Make microtime() return the correct time on %tick machines.

Re-enable debug stuff in dostart for now to detect kernel mapping issues.

eeh 1090c8a9cf probeget() actually handles 64-bit values so fix the prototype. 2000-09-28 19:16:35 +00:00
eeh 0ca74ba0d8 Fix the `trap type 0x10' problem. Apparently, something has changed and 
now makes use of lockmgr().  Since we broke into the debugger from an interrupt,
we don't have a curproc, so when lockmgr() tries to find our PID it barfs,
causing another break into DDB which then calls the mysterious code that
calls lockmgr() again.....

So set doing_shutdown while we're in DDB so lockmgr ignores locks.

jdolecek 49c105ffdb add new macro BOOT_FLAG() (defined in <sys/boot_flag.h>) - this 
maps standard boot flags to corresponding RB_* values
use BOOT_FLAG() in port's MD code as appropriate

as discussed on tech-kern, add new boot flags -v, -q for booting
verbosely or quietly, and corresponding AB_VERBOSE/AB_QUIET
boot flags; also add FreeBSD-compatible bootverbose macro and
NetBSD-specific bootquiet macro

for hpcmips, use new bootverbose instead of it's own hpcmips_verbose

Tested on i386, and to limited extend (compile of affected files) also for
mvme68k, hp300, luna68k, sun3.

thorpej 72a24b4eae Add an align argument to uvm_map() and some callers of that 
routine.  Works similarly fto pmap_prefer(), but allows callers
to specify a minimum power-of-two alignment of the region.
How we ever got along without this for so long is beyond me.
