On newer HW (Xe2 onwards + PVC) it is possible to get extra information when a CAT error occurs, specifically a dword reporting the error type. To enable this extra reporting, we need to opt-in with the GuC, which is done via a specific per-VF feature opt-in H2G. On platforms where the HW does not support the extra reporting, the GuC will set the type to 0xdeadbeef, so we can keep the code simple and opt-in to the feature on every platform and then just discard the data if it is invalid. Note that on native/PF we're guaranteed that the opt in is available because we don't support any GuC old enough to not have it, but if we're a VF we might be running on a non-XE PF with an older GuC, so we need to handle that case. We can re-use the invalid type above to handle this scenario the same way as if the feature was not supported in HW. Given that this patch is the first user of the guc_buf_cache on native and VF, it also extends that feature to non-PF use-cases. v2: simpler print for the error type (John), rebase v3: use guc_buf_cache instead of new alloc, simpler doc (Michal) Signed-off-by: Daniele Ceraolo Spurio <daniele.ceraolospurio@intel.com> Cc: Nirmoy Das <nirmoy.das@intel.com> Cc: John Harrison <John.C.Harrison@Intel.com> Cc: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: Nirmoy Das <nirmoy.das@intel.com> #v1 Reviewed-by: Michal Wajdeczko <michal.wajdeczko@intel.com> Reviewed-by: John Harrison <John.C.Harrison@Intel.com> Link: https://lore.kernel.org/r/20250625205405.1653212-3-daniele.ceraolospurio@intel.com
