I have make in '/usr/src/lib/libpthread', I found some new things in '/usr/lib' as follow: lrwxr-xr-x 1 root wheel 11 Dec 11 16:04 libkse.so -> libkse.so.1 -r--r--r-- 1 root wheel 68780 Dec 11 16:04 libkse.so.1 -r--r--r-- 1 root wheel 164448 Dec 11 16:04 libkse_p.a -r--r--r-- 1 root wheel 153854 Dec 11 16:04 libkse.a So if I program. How can I use the kse? I can use pthread(3) as traditional manner, only using '-lpthread' instead of '-pthread' in my makefile, right? when I use /usr/src/tools/KSE/ksetest/ksetest program , it always cause my box crash. I have report this issue to Julian. I am seeing KSE(2), I have some puzzles about that. 1. upcall is really means what? Does it represent through 'km_func'? if it were true, the 'km_func' is indicated by whom? UTS, Kernel, or user program, I do not know. 2. When one process has more than one KSEG, the signal should be delivered to which KSEG? The manual said it is indeterminate. I do not know how the signal could be delivered to the special KSEG exactly? Thank you!
