Do you think it is worth defining an interface for GuC to return the sw
ctx_id it will be using for a ctx, say at ctx registration time?
Umesh, I came across these in GuC documentation:
guc_pcv1_context_parameters_set_h2g_data_t::context_id
guc_pcv2_context_parameters_set_h2g_data_t::context_id
Also in the code we have in prepare_context_registration_info_v70 'ctx_id =
ce->guc_id.id' which seems to be assigned in new_guc_id. So wondering if
this is what we need and we already have it?
this id is different from what GuC programs into the lrca.
Thanks,
Umesh
Thanks.
