Subject: Re: [RFC][PATCH 3/3] x86: make MP a required-feature on 64-bit
Date: Fri, 20 Jun 2014 10:50:25 -0700 [thread overview]
Message-ID: <53A47461.4050409@zytor.com> (raw)
In-Reply-To: <20140620174345.GD11391@pd.tnic>
Looking at the AMD init code, there is a whole bunch of other 32/64-bit
differences that are clearly bogus. I also see that amd_k7_smp_check()
doesn't even *exist* on 64 bits, and that init_amd_k7() which calls
amd_k7_smp_check() only is ever called for family == 6, despite having
tests for family 7 and above in it.
Urgh.
Borislav, any way that you would be willing to take this on, or get
someone from AMD to clean up this mess?
