[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v14 18/23] x86: L2 CAT: implement get value flow.
This patch implements L2 CAT get value interface in domctl. Signed-off-by: Yi Sun <yi.y.sun@xxxxxxxxxxxxxxx> Reviewed-by: Jan Beulich <jbeulich@xxxxxxxx> --- v14: - rebase domctl.c on latest codes: bool_t is replace by bool. v11: - remove "get_val' assignment because it has been replaced by generic codes. (suggested by Jan Beulich) v10: - remove cast in domctl. (suggested by Jan Beulich) v9: - reuse 'cat_get_val' for L2 CAT to reduce redundant codes (suggested by Roger Pau) - changes about 'uint64_t' to 'uint32_t'. (suggested by Jan Beulich) v5: - remove type check in callback function. (suggested by Jan Beulich) v4: - create this patch because of codes architecture change.
