radeontop

Show the utilisation of the default AMD GPU

$ radeontop

Enable colored output

$ radeontop --color

Select a specific GPU (the bus number is the first number in the output of lspci)

$ radeontop --bus [bus_number]

Specify the display refresh rate (higher means more GPU overhead)

$ radeontop --ticks [samples_per_second]

radeontop [-chmv] [-b bus] [-d file] [-l limit] [-i secs] [-p device] [-t ticks]

RadeonTop shows the utilization of your GPU, both in general and by blocks.

Supported cards are R600 and up.

-b, --bus bus

If you have multiple cards, use this parameter to select a specific one. For lspci output 01:00.0 VGA compatible controller, bus would be 1.

-c, --color

Enables colorized output.

-d, --dump file

Instead of displaying the data, dump it to file. Use - for stdout. The file is appended to, so it’s safe to specify the same filename for consecutive runs.

Use SIGTERM or SIGINT for graceful termination.

-h, --help

Displays help.

-i, --dump-interval seconds

Wait for N seconds between data output.

-l, --limit limit

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, --path device

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, --ticks ticks

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.

C, c

Toggle colorized output.

Q, q

Quit.
