Subject: [PATCH V3 05/10] powerpc/mm: Add translation mode information in /proc/cpuinfo
Date: Tue, 21 Mar 2017 22:59:55 +0530 [thread overview]
Message-ID: <1490117400-9891-5-git-send-email-aneesh.kumar@linux.vnet.ibm.com> (raw)
In-Reply-To: <1490117400-9891-1-git-send-email-aneesh.kumar@linux.vnet.ibm.com>
With this we have on powernv and pseries /proc/cpuinfo reporting
timebase : 512000000
platform : PowerNV
model : 8247-22L
machine : PowerNV 8247-22L
firmware : OPAL
MMU : Hash
