Could someone please ack this? We need this before getting HuC. GuC submission has regressions so the submission is not getting enabled. But we need to have GuC loaded to be able to use HuC.

It is ok if command submission is not happening through GuC but GuC "has to" be loaded for HuC to function. Guc_submission parameter enables the command submission through GUC. But, guc_loading parameter ensures not only that the GuC is loaded but also that HuC can now function. >> >> Anusha >>>-- >>>Chris Wilson, Intel Open Source Technology Centre >> _______________________________________________ >> Intel-gfx mailing list >> Intel-gfx@xxxxxxxxxxxxxxxxxxxxx >> https://lists.freedesktop.org/mailman/listinfo/intel-gfx > > > > -- > Rodrigo Vivi > Blog: http://blog.vivi.eng.br -- Rodrigo Vivi Blog: http://blog.vivi.eng.br _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
