The GuC compatibility version that we read from the CSS header in native/PF and the GuC VF version that we get when a VF handshakes with the GuC are the same version number, so we should store it into the same structure. This makes all the checks based on the compatibility version automatically work for VFs without having to copy the value over. For completion, also copy the wanted version and set the path to a known string to indicate that the FW is PF-loaded. This way all the info will be coherent when dumped from debugfs. v2: several code cleanups and style changes (Michal), rebase on bootstrap changes. v3: s/min/wanted/, clarify that handshake must happen before we can get the VF versions (Michal) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Cc: Lukasz Laguna <lukasz.laguna@intel.com> Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Link: https://lore.kernel.org/r/20250603235432.720833-10-daniele.ceraolospurio@intel.com
