[PATCH] drm/i915: Noop lrc_init_wa_ctx() on recent/future platforms

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Except for graphics version 8 and 9, nothing is done in
lrc_init_wa_ctx(). Assume this won't be needed on future platforms as
well and remove the warning.

Note that this function is not called for anything below version 8 since
those don't use either guc or execlist, i.e. HAS_EXECLISTS() is false.
