From: Heiko Carstens Date: Mon, 27 Jun 2016 11:19:22 +0000 (+0200) Subject: s390/cpuinfo: show maximum thread id X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=10f4954ae67b3be6dac3cdfb1e0057c3779542be;p=linux-beck.git s390/cpuinfo: show maximum thread id Expose the maximum thread id with /proc/cpuinfo. With the new line the output looks like this: vendor_id : IBM/S390 bogomips per cpu: 20325.00 max thread id : 1 With this new interface it is possible to always tell the correct number of cpu threads potentially being used by the kernel.
