Subject: Re: + restore-missing-sysfs-max_cstate-attr.patch added to -mm tree
Date: Mon, 7 Jan 2008 14:12:59 -0500 [thread overview]
Message-ID: <200801071412.59964.lenb@kernel.org> (raw)
In-Reply-To: <4782400D.2040802@rtr.ca>
1. Why does VMware need max_cstate=1 to load quickly?
It should not, and the fact that it does means
that something somewhere is seriously broken.
2. Why does the "max_csate=1" workaround help only
on the dual-core boxes, while the single-core
boxes still fail to load quickly?
I'm glad that we deleted run-time access to max_cstate --
it seems to have exposed a real bug that needs fixing
and has gone unreported until now.
Indeed, when the real bug is fixed, I propose that
we again move to delete max_cstate as a run-time API.
