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

 



These patches add HuC loading support. The GuC is required to 
authenticate the HuC. The userspace patches that check for a 
fully loaded HuC firmware and use it can be found at:

v4: Added action_lock initialization fix provided by Arek
(Hiler Arkadiusz) to the first patch in the series- Make the
GuC fw loading helper functions general.

code reorganization efforts by Arek-

v6: rebased. Organize the code-move contents of intel_huc.h to intel_uc.h. Update functions
intel_huc_load(),intel_huc_init() and intel_uc_fw_fetch() to accept dev_priv instead of dev.
