[Mesa-dev] [PATCH v2 2/4] egl, dri: Propagate context priority hint to driver->CreateContext
Chris Wilson
chris at chris-wilson.co.uk
Tue Apr 11 16:11:55 UTC 2017
Jump through the layers of abstraction between egl and dri in order to
feed the context priority attribute through to the backend. This
requires us to read the value from the base _egl_context, convert it to
a DRI attribute, parse it again in the generic context creator before
passing it to the driver as a function parameter.
In order to not require us to pass back the actual value of the context
priority after creation, we impose that drivers should report the
available set of priorities during screen setup (and then they may chose
to fail if given an invalid value as that should have been checked at
the user boundary.)
