From: Ido Schimmel <[email protected]> The switch ASIC has a limited capacity of physical ports that it can support. While each system is brought up with a different number of ports, this number can be increased via splitting up to the ASIC's limit.
Expose physical ports as a devlink resource so that user space will have visibility into the maximum number of ports that can be supported and the current occupancy. With this resource it is possible, for example, to write generic (i.e., not platform dependent) tests for port splitting. Patch #1 adds the new resource and patch #2 adds a selftest. v2: * Add the physical ports resource as a generic devlink resource so that it could be re-used by other device drivers Danielle Ratson (2): mlxsw: Register physical ports as a devlink resource selftests: mlxsw: Add a scale test for physical ports .../networking/devlink/devlink-resource.rst | 14 ++++ drivers/net/ethernet/mellanox/mlxsw/core.c | 77 ++++++++++++++++--- drivers/net/ethernet/mellanox/mlxsw/core.h | 5 ++ .../net/ethernet/mellanox/mlxsw/spectrum.h | 2 +- include/net/devlink.h | 2 + net/core/devlink.c | 4 + .../selftests/drivers/net/mlxsw/port_scale.sh | 64 +++++++++++++++ .../net/mlxsw/spectrum-2/port_scale.sh | 16 ++++ .../net/mlxsw/spectrum-2/resource_scale.sh | 2 +- .../drivers/net/mlxsw/spectrum/port_scale.sh | 16 ++++ .../net/mlxsw/spectrum/resource_scale.sh | 2 +- 11 files changed, 191 insertions(+), 13 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/mlxsw/port_scale.sh create mode 100644 tools/testing/selftests/drivers/net/mlxsw/spectrum-2/port_scale.sh create mode 100644 tools/testing/selftests/drivers/net/mlxsw/spectrum/port_scale.sh -- 2.29.2
