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. A sample output after applying this script - root@ubuntu:~# cpupower f<TAB> root@ubuntu:~# cpupower frequency-<TAB> frequency-info frequency-set root@ubuntu:~# cpupower frequency-set - -d --freq --governor --min --related -f -g --max -r -u root@ubuntu:~# cpupower frequency-set -g <TAB> conservative ondemand performance powersave schedutil userspace root@ubuntu:~# cpupower frequency-set -f <TAB> 2061000 2194000 2327000 2460000 2593000 2726000 2859000 2094000 2227000 2360000 2493000 2626000 2759000 2892000 2128000 2261000 2394000 2527000 2660000 2793000 2926000 2161000 2294000 2427000 2560000 2693000 2826000 2959000 root@ubuntu:~# cpupower frequency-set -f 206<TAB> root@ubuntu:~# cpupower frequency-set -f 2061000 Signed-off-by: Abhishek Goel <huntbag@linux.vnet.ibm.com> Signed-off-by: Bharath Thodla <bharath.thodla@in.ibm.com> Tested-by: Thomas Renninger <trenn@suse.de> Signed-off-by: Shuah Khan <shuah@kernel.org>
