Add script to manage Intel GPU frequencies. It can be used for debugging performance problems or to lock a stable frequency while executing benchmark tests. Typical use cases: - Get all available GPU frequency information $ ./intel-gpu-freq.sh -g all * Hardware capabilities RP0: 1350 MHz RPn: 100 MHz RP1: 400 MHz * Enforcements max: 1350 MHz min: 100 MHz boost: 1350 MHz * Actual act: 100 MHz cur: 400 MHz - Lock frequency to 80% of the maximum allowed by hardware and enable throttling detection $ ./intel-gpu-freq.sh -s 80% -d GPU throttling detected: act=1050 min=1350 cur=1350 RPn=100 GPU throttling detected: act=1100 min=1350 cur=1350 RPn=100 Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@collabora.com> Acked-by: Tomeu Vizoso <tomeu.vizoso@collabora.com> Reviewed-by: Guilherme Gallo <guilherme.gallo@collabora.com> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/15662>

Other repositories are likely forks, and code found there is not supported. Build & install --------------- You can find more information in our documentation (`docs/install.rst <https://mesa3d.org/install.html>`_), but the recommended way is to use Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_): .. code-block:: sh $ mkdir build $ cd build $ meson .. $ sudo ninja install Support ------- Many Mesa devs hang on IRC; if you're not sure which channel is appropriate, you should ask your question on `OFTC's #dri-devel <irc://irc.oftc.net/dri-devel>`_, someone will redirect you if necessary.
