Subject: Re: [PATCH] powerpc: update ibm,client-architecture
Please give this a more appropriate name.
Any suggestions?
In order to boot with more than 64 cores on machines that support the
ibm,client-architecture RTAS call a new field has been added to the
structure. This patch updates that field and adds a few others in the
process.
Please detail what these are here.
OK.
+ W(NR_CPUS/4), /* max cores supported */
4?
4 is the new 2. Since you don't know the actual threads per core at
this point in boot you have to be conservative and go with the maximum
number of any processor. See page 4 of these charts:

Can we do this now or remove the comment. Maybe UTS_RELEASE or
something like that.
I'll just remove the comment for now.
