Re: [Gems-users] OPAL warning

[Luke Yen <lyen@xxxxxxxxxxx>]

Arrvindh,

  This means that Opal does not have mappings for the control registers
like 'g1' in its m_control_map, which is read using getControl() (see pseq.C for
examples).  It can be a problem if the benchmark needs access to those
registers for its execution.  The list of control registers that Opal
currently has mapped is in pstate.C, in control_reg_menomic[].  Note that the global
registers and register windows are implemented separately, in regbox.C/h.
