* The function ksprintn(), which is used to convert numbers to ASCII, is notarchie1999-06-061-8/+14
| | | | | reentrant because it returns a static buffer. This results in a race condition when/if an interrupt handler calls log(), printf() etc. Fix this.

* Store formatted panic string in static buffer to make it available laterache1998-09-061-1/+14
| | | | | for savecore. Previous code give only panic format to savecore
* Fixed the formatting of some tables (mainly the one produced by psbde1998-08-101-2/+2
| | | | | | | | | | in ddb) which I broke by changing %8[l]x to %8p. Hacked the central printf routine to not add an "0x" prefix for %p formats if the field width is nonzero. The tables are still horribly misformatted on 64-bit machines. Use %p instead of %8p to print pointers when the field width isn't important.
* Cast pointers to uintptr_t/intptr_t instead of to u_long/long,bde1998-07-151-2/+2
| | | | | | | respectively. Most of the longs should probably have been u_longs, but this changes is just to prevent warnings about casts between pointers and integers of different sizes, not to fix poorly chosen types.
* Fixed (un)sign extension bugs in %+n format. -4 becamebde1998-07-081-7/+16
| | | | | | | | | | | | | | | (long)(u_long)(u_int)-4 = 0x00000000fffffffc on machines with 32-bit ints and 64-bit longs. Restored %z format for printing signed hex. %+x shouldn't have been used since it is an error in userland. Prepared to nuke %n format by cloning it to %r. %n shouldn't have been used because it means something completely different in userland. Now %+r is equivalent to ddb's original %r, and %r is equivalent to ddb's original %n. Ignore '+' flag in combination with unsigned formats %{o,p,u,x}.
* Some cleanups related to timecounters and weird ifdefs in <sys/time.h>.phk1998-05-281-4/+45
| | | | | | | | | | | | | | | | | | | | Clean up (or if antipodic: down) some of the msgbuf stuff. Use an inline function rather than a macro for timecounter delta. Maintain process "on-cpu" time as 64 bits of microseconds to avoid needless second rollover overhead. Avoid calling microuptime the second time in mi_switch() if we do not pass through _idle in cpu_switch() This should reduce our context-switch overhead a bit, in particular on pre-P5 and SMP systems. WARNING: Programs which muck about with struct proc in userland will have to be fixed. Reviewed, but found imperfect by: bde

(I'm sure Søren will do the syscons part RSN). I've still got one occasion where the system stalled, but my attempts to trigger the situation artificially resulted int the expected behaviour. It's hard to track bugs without the console and DDB available. :-/
