      devlink: Support for pipeline debug (dpipe) · 1555d204
      Arkadi Sharshevsky 提交于
      The pipeline debug is used to export the pipeline abstractions for the
      main objects - tables, headers and entries. The only support for set is
      for changing the counter parameter on specific table.
      
      The basic structures:
      
      Header - can represent a real protocol header information or internal
               metadata. Generic protocol headers like IPv4 can be shared
               between drivers. Each driver can add local headers.
      
      Field - part of a header. Can represent protocol field or specific ASIC
              metadata field. Hardware special metadata fields can be mapped
              to different resources, for example switch ASIC ports can have
              internal number which from the systems point of view is mapped
              to netdeivce ifindex.
      
      Match - represent specific match rule. Can describe match on specific
              field or header. The header index should be specified as well
              in order to support several header instances of the same type
              (tunneling).
      
      Action - represents specific action rule. Actions can describe operations
               on specific field values for example like set, increment, etc.
               And header operation like add and delete.
      
      Value - represents value which can be associated with specific match or
              action.
      
      Table - represents a hardware block which can be described with match/
              action behavior. The match/action can be done on the packets
              data or on the internal metadata that it gathered along the
              packets traversal throw the pipeline which is vendor specific
              and should be exported in order to provide understanding of
              ASICs behavior.
      
      Entry - represents single record in a specific table. The entry is
              identified by specific combination of values for match/action.
      
      Prior to accessing the tables/entries the drivers provide the header/
      field data base which is used by driver to user-space. The data base
      is split between the shared headers and unique headers.

      Introduce devlink infrastructure · bfcd3a46
      Jiri Pirko 提交于
      Introduce devlink infrastructure for drivers to register and expose to
      userspace via generic Netlink interface.
      
      There are two basic objects defined:
      devlink - one instance for every "parent device", for example switch ASIC
      devlink port - one instance for every physical port of the device.
      
      This initial portion implements basic get/dump of objects to userspace.
      Also, port splitter and port type setting is implemented.
