Subject: [PATCH] x86: hpet: Don't default CONFIG_HPET_TIMER to be y for X86_64
Date: Thu, 27 Mar 2014 15:45:09 +0800 [thread overview]
Message-ID: <1395906309-7519-1-git-send-email-feng.tang@intel.com> (raw)
On many new phone/tablet platforms like Baytrail/Merrifield etc,
the HPET are either defeatured or has some problem to be used
as a reliable timer. As these platforms also have X86_64, we
should not make HPET_TIMER default y for all X86_64.
