If you have multiple cards, use this parameter to select a specific one. For lspci output 01:00.0VGAcompatiblecontroller, bus would be 1.
-c,--color
Enables colorized output.
-d,--dumpfile
Instead of displaying the data, dump it to file. Use - for stdout. The file is appended to, so itβs
safe to specify the same filename for consecutive runs.
Use SIGTERM or SIGINT for graceful termination.
-h,--help
Displays help.
-i,--dump-intervalseconds
Wait for N seconds between data output.
-l,--limitlimit
Quit after dumping limit lines. Only valid in dump mode. Default is to dump until terminated; use
SIGTERM or SIGINT for graceful termination.
-m,--mem
Forces the use of the /dev/mem path, in case autodetection fails. Useful for the proprietary driver.
-p,--pathdevice
Open the DRM device node specified by device path. Usually it is located at /dev/dri/card0 or
/dev/drm0. If this option used, --bus and --mem are ignored.
-t,--ticksticks
How many times per second to sample the data. The default is 120. Higher numbers mean more accurate
output and more overhead.
-v,--version
Displays the program version.
