I was running dxsysinfo on an AlphaServer 2100 running Steel X4.2-6 (Rev. 186) (aka bl6). The following two lines were printf'd to the DECterm I used to launch dxsysinfo: lock statistics not supported in lockmode 0 or 1 lock statistics not supported in lockmode 0 or 1 Who printed this message? What does it mean? pete

The messages are printed by the /usr/sbin/lockinfo command. Looks
like dxsysinfo trys to gather lockstatistics....

I guess that this is still true for steel.
depending on the lockmode the operating system uses different
code pathes for the lock primitives.
for lockmode 0 which is used when neither Realtime and SMP is
required, the lock prinitives are patched out completly.
lockmode 1 is used when only RT is required. it just uses
an preemption blocking count than.
so in both cases there is no need (way) to maintain statistics
and due to this they can't be collected.

re: .1 Actually, I'm pretty sure sysinfo doesn't do anything at all with lock stats. It get file system stats, swap stats, vm stats and that's about it. Could one of the related calls for these functions have caused this message to be produced? Pete | |||||
