Subject: [PATCH v9 3/5] powerpc/hv-24x7: Add sysfs files inside hv-24x7 device to show processor details
Date: Mon, 18 May 2020 17:34:50 +0530 [thread overview]
Message-ID: <20200518120452.15082-4-kjain@linux.ibm.com> (raw)
In-Reply-To: <20200518120452.15082-1-kjain@linux.ibm.com>
To expose the system dependent parameter like total number of
sockets and numbers of chips per socket, patch adds two sysfs files.
"sockets" and "chips" are added to /sys/devices/hv_24x7/interface/
of the "hv_24x7" pmu.
