Hi, This series by Or adds devlink per-port resource support. See detailed description by Or below [1].
Regards, Tariq [1] Currently, devlink resources are only available at the device level. However, some resources are inherently per-port, such as the maximum number of subfunctions (SFs) that can be created on a specific PF port. This limitation prevents user space from obtaining accurate per-port capacity information. This series adds infrastructure for per-port resources in devlink core and implements it in the mlx5 driver to expose the max_SFs resource on PF devlink ports. Patch #1 refactors resource functions to be generic Patch #2 adds port-level resource registration infrastructure Patch #3 registers SF resource on PF port representor in mlx5 Patch #4 adds devlink port resource registration to netdevsim for testing Patch #5 adds dump support for device-level resources Patch #6 includes port resources in the resource dump dumpit path Patch #7 adds port-specific option to resource dump doit path Patch #8 adds selftest for devlink port resource doit Patch #9 documents port-level resources and full dump Patch #10 adds resource scope filtering to resource dump Patch #11 adds selftest for resource dump and scope filter Patch #12 documents resource scope filtering Userspace patches for iproute2: https://github.com/ohartoov/iproute2/tree/port_resources V5: - Link to V4: https://lore.kernel.org/all/[email protected]/ - Change resource scope attribute from bitmask to u32 - Remove max value and valid mask define for scope attribute - Handle the case where a device is unregistered or a port is removed in the middle of a multi-callback dump (Sashiko's comment) - Replace port_number with port_index and add an index_valid bool to the dump state to track the port resources phase of the dump (Sashiko's comment) Or Har-Toov (12): devlink: Refactor resource functions to be generic devlink: Add port-level resource registration infrastructure net/mlx5: Register SF resource on PF port representor netdevsim: Add devlink port resource registration devlink: Add dump support for device-level resources devlink: Include port resources in resource dump dumpit devlink: Add port-specific option to resource dump doit selftest: netdevsim: Add devlink port resource doit test devlink: Document port-level resources and full dump devlink: Add resource scope filtering to resource dump selftest: netdevsim: Add resource dump and scope filter test devlink: Document resource scope filtering Documentation/netlink/specs/devlink.yaml | 32 +- .../networking/devlink/devlink-resource.rst | 70 ++++ .../net/ethernet/mellanox/mlx5/core/devlink.h | 4 + .../mellanox/mlx5/core/esw/devlink_port.c | 37 +++ drivers/net/netdevsim/dev.c | 23 +- drivers/net/netdevsim/netdevsim.h | 4 + include/net/devlink.h | 10 +- include/uapi/linux/devlink.h | 11 + net/devlink/devl_internal.h | 5 + net/devlink/netlink.c | 2 + net/devlink/netlink_gen.c | 24 +- net/devlink/netlink_gen.h | 8 +- net/devlink/port.c | 2 + net/devlink/resource.c | 314 +++++++++++++++--- .../drivers/net/netdevsim/devlink.sh | 79 ++++- 15 files changed, 568 insertions(+), 57 deletions(-) base-commit: c149d90e260ca1b6b9175468955a15c4d95a9f3b -- 2.44.0
