From 901d32bc69f3423ad53947b992f973123faf2622 Mon Sep 17 00:00:00 2001 From: Abhishek Goel Date: Wed, 5 Dec 2018 17:01:04 +0530 Subject: [PATCH] cpupower : Auto-completion for cpupower tool This script adds support for auto-completion for cpupower tool. Added support for auto-completion of all the eight commands for cpupower tool and their all subsequent sub-commands, wherever possible.
