Version 0.2 of patches to bge(4). I'm not totally happy with it, but comments welcome. I need better explanations of usage for the man page.
I've dropped bge_rxd completely here as it was suggested to not even bother adjusting it. http://people.freebsd.org/~sbruno/bge_config_update_1.txt > I didn't notice before that these are tunables and not sysctls. That's > much more broken. Actually tuning using them like I do with sysctls > would take ~10000 reboots. Tunables are bogus for anything that isn't > needed for booting. Optimizations are needed for booting. > Done and changed. Things seem to do the right thing when adjusted. > Technical bugs include: > - wrong defaults are claimed for *coal_ticks. The defaults are 150, but > are claimed to be 150 milliseconds. These values are dimensionless, > but since ticks take 1 microsecond each, 150 gives 150 microseconds, > not 150 milliseconds. man page updated to reflect usec timing. checked the tech docs as well and confirmed microseconds. > - *coal_bds is claimed to be a count of packes (sic). Actually, it is a > count of buffer descriptors. Small packets take 1 bd, but normal > packets take 2, and jumbo packets many (?). The best tuning may be > depend on the average bds/packet. man page updated with wording that attempts to say this. > - the new tunables are in the wrong namespace (hw instead of dev) fixed > - the new tunables are too global (bge instead of bge.N) fixed > > There are only 2 bge tunables now, and they only have half of these bugs: > - hw.bge.allow_asf is in the wrong namespace > - hw.bge.allow_asf is too global Maintainer disagrees with this. > - dev.bge.%d.msi seems to be correct. > Both of the old tunables are needed for boot-time configuration. > > Bruce Sean
