Subject: [RESEND PATCH 0/3] x86: structs for cpuid info in x86
Date: Wed, 17 Sep 2014 15:54:11 +0300 [thread overview]
Message-ID: <1410958454-7501-1-git-send-email-namit@cs.technion.ac.il> (raw)
In-Reply-To: <20140917124501.GC5358@nazgul.tnic>
The code that deals with x86 cpuid fields is hard to follow since it performs
many bit operations and does not refer to cpuid field explicitly. To
eliminate the need of openning a spec whenever dealing with cpuid fields, this
patch-set introduces structs that reflect the various cpuid functions.
Thanks for reviewing the patch-set.
