Yes, it is gone with 8.0. Disable the module builds because some of
them like this one probably need compile fixes. If you need a subset
of modules use MODULES_OVERRIDE=list (in /etc/make.conf)
Yes, kernel builds.
I'm still playing with it, but the first results shows that new kernel
can handle 800k incoming packets (well may be more but I have not enough
power right now to generate more packets).
It still answer only to 250K-260K. I guess I'm hitting the limitation of
syncache/syncookies ?
Anyway this netisr2 looks like huge improvement :)
I can't build kernel without option LOCK_PROFILING with your sources:
make -V CFILES -V SYSTEM_CFILES -V GEN_CFILES | MKDEP_CPP="cc -E"
CC="cc" xargs mkdep -a -f .newdep -O2 -frename-registers -pipe
-fno-strict-aliasing -march=nocona -std=c99 -g -Wall -Wredundant-decls
-Wnested-externs -Wstrict-prototypes -Wmissing-prototypes

mkdep: compile failed
*** Error code 1
So I added #include <sys/lock.h>, rebuild kernel and tested again w/o
LOCK_PROFILING, but results are the same.
I'll use again hwpmc and LOCK_PROFILING to see what's going on.
And will try the same benchmark on quad core processor as now numbers of
cores/cpus matter :)
