| |
This series provides knobs which will enable users to minimize memory consumption of mlx5 Functions (PF/VF/SF). mlx5 exposes two new generic devlink params for EQ size configuration and uses devlink generic param max_macs.
Patches summary: - Patch-1 Introduce log_max_current_uc_list_wr_supported bit - Patches-2-3 Provides I/O EQ size param which enables to save up to 128KB. - Patches-4-5 Provides event EQ size param which enables to save up to 512KB. - Patch-6 Clarify max_macs param. - Patch-7 Provides max_macs param which enables to save up to 70KB
In total, this series can save up to 700KB per Function.
--- changelog: v2->v3: - change type of EQ size param to u32 per Jiri suggestion. - separate ifc changes to new patch v1->v2: - convert io_eq_size and event_eq_size from devlink_resources to generic devlink_params
Shay Drory (7): net/mlx5: Introduce log_max_current_uc_list_wr_supported bit devlink: Add new "io_eq_size" generic device param net/mlx5: Let user configure io_eq_size param devlink: Add new "event_eq_size" generic device param net/mlx5: Let user configure event_eq_size param devlink: Clarifies max_macs generic devlink param net/mlx5: Let user configure max_macs generic param
