Lucas Stach ea754657eb etnaviv: drm: use COARSE clock for BO cache timing
By using the the COARSE variant of the clock we can avoid a syscall
to fetch the current time on platforms where the more accurate
version of the clock can not be accelerated through the VDSO. The
most relevant platform with this restriction is ARM32 without the
architected timer extension, e.g. the NXP i.MX6.

The COARSE clock degrades the accuracy of the timing to Linux
jiffies, which means it adds a worst-case jitter of 10ms, which is
basically noise in relation to the 1sec holding time of the cache
and the irregular call pattern of etna_bo_cache_cleanup().

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
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://docs.mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://docs.mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install

appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
