Subject: [PATCH 13/14] topology: Create core_threads sysfs attribute
Date: Tue, 26 Feb 2019 01:20:11 -0500 [thread overview]
Message-ID: <8c68d2dfd5d516316444b1a25fe550bb42733eb8.1551160674.git.len.brown@intel.com> (raw)
In-Reply-To: <e2810a5317d3a109a98204e883fd1461f77b9339.1551160674.git.len.brown@intel.com>
From: Len Brown <len.brown@intel.com>
Create CPU topology sysfs attributes:
"core_threads" and "core_threads_list"
These attributes represent all of the logical CPU threads that share the
same core.
These attriutes is synonymous with the existing "thread_siblings" and
"thread_siblings_list" attribute, which will be deprecated.
