[PATCH v2 1/2] drm/i915/huc: Move pending status before debug

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

 



From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>

This avoids confusing log message sequences such as:

 [] i915/skl_huc_ver01_07_1398.bin fw status: fetch SUCCESS, load SUCCESS
 [] HuC DMA transfer wait over with ret 0
 [] i915/skl_huc_ver01_07_1398.bin fw status: fetch SUCCESS, load SUCCESS

v2:

Michal and Michał noticed that there is an impossible condition
introduced by v1, which is also preventing  second attempts of
firmware load after reset. This has now been removed.

I also removed the fetch status check on the fail path which
looks redundant as well.

I've just realized these two patches would create a conflict for
Arek's GuC/HuC tidy series. Feel free to incorporate them into
that work then if it is easier.
