[PATCH 03/21] drm/i915/gem: Set the watchdog timeout directly in intel_context_set_gem

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

 



Instead of handling it like a context param, unconditionally set it when
intel_contexts are created.  This doesn't fix anything but does simplify
the code a bit.
