Hi,
I'm porting x86info to opensolaris. Among many options, x86info try to
access MSR registers(MTRR, TSC, etc.), but x86 CPU allows MSR access
only in RING 0 privilege. In order to allow access from userspace,
there have to be a msr driver in kernel to handle it.
Does opensolaris has such a driver? It should be easy to implement from
technical perspective.
It's not included, but I did exactly the same thing not long ago. You're
welcome to the code if you want it, but it would take some work to actually
include with Solaris (and I'm not sure it would be a great idea to have it there
anyway).
