From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
In the previous patch we switched the lsgpu output to a short and user
friendly format but some users will need a shorthand for getting other
types of device selection filters than the defaut drm.
Add some command line switches to enable this:
$ lsgpu
card0 8086:193B drm:/dev/dri/card0
└─renderD128 drm:/dev/dri/renderD128
$ lsgpu --sysfs
card0 8086:193B sys:/sys/devices/pci0000:00/0000:00:02.0/drm/card0
└─renderD128 sys:/sys/devices/pci0000:00/0000:00:02.0/drm/renderD128
$ lsgpu --pci
card0 8086:193B pci:vendor=8086,device=193B,card=0
└─renderD128
v2:
* Fix pci filter format.
