Message-Id: <20220712103154.2805695-1-jiri@resnulli.us> Date: Tue, 12 Jul 2022 12:31:54 +0200 From: Jiri Pirko <jiri@...nulli.us> To: netdev@...r.kernel.org Cc: sthemmin@...rosoft.com, dsahern@...il.com, mlxsw@...dia.com Subject: [patch iproute2/net-next] devlink: add support for linecard show and type set From: Jiri Pirko <jiri@...dia.com> Introduce a new object "lc" to add devlink support for line cards with two commands: show - to get the info about the line card state, list of supported types as reported by kernel/driver. set - to set/clear the line card type. Example: $ devlink lc pci/0000:01:00.0: lc 1 state unprovisioned supported_types: 16x100G lc 2 state unprovisioned supported_types: 16x100G lc 3 state unprovisioned supported_types: 16x100G lc 4 state unprovisioned supported_types: 16x100G lc 5 state unprovisioned supported_types: 16x100G lc 6 state unprovisioned supported_types: 16x100G lc 7 state unprovisioned supported_types: 16x100G lc 8 state unprovisioned supported_types: 16x100G To provision the slot #8: $ devlink lc set pci/0000:01:00.0 lc 8 type 16x100G $ devlink lc show pci/0000:01:00.0 lc 8 pci/0000:01:00.0: lc 8 state active type 16x100G supported_types: 16x100G To uprovision the slot #8: $ devlink lc set pci/0000:01:00.0 lc 8 notype Signed-off-by: Jiri Pirko <jiri@...dia.com> --- devlink/devlink.c | 210 +++++++++++++++++++++++++++++++++++++++++- man/man8/devlink-lc.8 | 103 +++++++++++++++++++++ 2 files changed, 310 insertions(+), 3 deletions(-) create mode 100644 man/man8/devlink-lc.8 diff --git a/devlink/devlink.c b/devlink/devlink.c index ddf430bbb02a..1e2cfc3d4285 100644 --- a/devlink/devlink.c +++ b/devlink/devlink.c @@ -294,6 +294,8 @@ static void ifname_map_free(struct ifname_map *ifname_map) #define DL_OPT_PORT_FN_RATE_TX_MAX BIT(49) #define DL_OPT_PORT_FN_RATE_NODE_NAME BIT(50) #define DL_OPT_PORT_FN_RATE_PARENT BIT(51) +#define DL_OPT_LINECARD BIT(52) +#define DL_OPT_LINECARD_TYPE BIT(53) struct dl_opts { uint64_t present;
