Hello
ktrace tends to be useless when dealing with sysctl calls. I made a patch
that traces sysctl activity, like this:
108 1 sysctl CALL __sysctl(0xbfbfecb0,3,0xbfbfdad0,
0xbfbfdacc,0,0)
108 1 sysctl MIB 1.1118.1120
108 1 sysctl GIO read 7 bytes
"amdpm0\0"
108 1 sysctl RET __sysctl 0
Or, with a write operation:
303 1 sysctl CALL __sysctl(0xbfbfec30,3,0xbfbfebf0,
0xbfbfebd4,0xbfbfebec,4)
303 1 sysctl MIB 10.764.4
303 1 sysctl GIO read 4 bytes
"\0\0\0\0"
303 1 sysctl GIO wrote 4 bytes
"\0\0\0\0"
303 1 sysctl RET __sysctl 0
Here is the patch: http://ftp.espci.fr/shadow/manu/mib2.patch
Is it okay to commit?
