[Intel-gfx] [PATCH v2] drm/i915/guc: Retry GuC load for all load failures

[Chris Wilson]

Quoting Robert M. Fosha (2019-03-29 23:17:46)
> Currently we only retry to load GuC firmware if the load fails due to
> timeout. On Gen9 GuC loading may fail for different reasons, not just
> hang/timeout. Direction from the GuC team is to retry for all cases of
> GuC load failure on Gen9, not just for timeout.

Worst case is we get the same error 3 times before giving up.
