Improved non-statistical (GUPROF) profiling: - use a more accurate and more efficient method of compensating for overheads. The old method counted too much time against leaf functions. - normally use the Pentium timestamp counter if available. On Pentiums, the times are now accurate to within a couple of cpu clock cycles per function call in the (unlikely) event that there are no cache misses in or caused by the profiling code. - optionally use an arbitrary Pentium event counter if available. - optionally regress to using the i8254 counter. - scaled the i8254 counter by a factor of 128. Now the i8254 counters overflow slightly faster than the TSC counters for a 150MHz Pentium :-) (after about 16 seconds). This is to avoid fractional overheads. files.i386: permon.c temporarily has to be classified as a profiling-routine because a couple of functions in it may be called from profiling code. options.i386: - I586_CTR_GUPROF is currently unused (oops). - I586_PMC_GUPROF should be something like 0x70000 to enable (but not use unless prof_machdep.c is changed) support for Pentium event counters. 7 is a control mode and the counter number 0 is somewhere in the 0000 bits (see perfmon.h for the encoding). profile.h: - added declarations. - cleaned up separation of user mode declarations. prof_machdep.c: Mostly clock-select changes. The default clock can be changed by editing kmem. There should be a sysctl for this. subr_prof.c: - added copyright. - calibrate overheads for the new method. - documented new method. - fixed races and and machine dependencies in start/stop code. mcount.c: Use the new overhead compensation method. gmon.h: - changed GPROF4 counter type from unsigned to int. Oops, this should be machine-dependent and/or int32_t. - reorganized overhead counters. Submitted by: Pentium event counter changes mostly by wollman

Multiple changes stacked as one commit since they all depend on one another. First, change sysinstall and the Makefile rules to not build the kernel nlist directly into sysinstall now. Instead, spit it out as an ascii file in /stand and parse it from sysinstall later. This solves the chicken-n- egg problem of building sysinstall into the fsimage before BOOTMFS is built and can have its symbols extracted. Now we generate the symbol file in release.8. Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two effects: 1. Userconfig is always entered, rather than only after a -c (don't scream yet, it's not as bad as it sounds). 2. Userconfig reads a message string which can optionally be written just past the boot blocks. This string "preloads" the userconfig input buffer and is parsed as user input. If the first command is not "USERCONFIG", userconfig will treat this as an implied "quit" (which is why you don't need to scream - you never even know you went through userconfig and back out again if you don't specifically ask for it), otherwise it will read and execute the following commands until a "quit" is seen or the end is reached, in which case the normal userconfig command prompt will then be presented. How to create your own startup sequences, using any boot.flp image from the next snap forward (not yet, but soon): % dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO USERCONFIG irq ed0 10 iomem ed0 0xcc000 disable ed1 quit WAKKA_WAKKA_DOO Third, add an intro screen to UserConfig so that users aren't just thrown into this strange screen if userconfig is auto-launched. The default boot.flp startup sequence is now, in fact, this: USERCONFIG intro visual (Since visual never returns, we don't need a following "quit"). Submitted-By: phk & jkh
