For\nexample, some two port devices will report as functions 0 and 2.\n\nWhen distributing RSS and FDIR masks, which are global resources across\nthe active devices, it is required to have a contiguous PF id, which can\nbe described as a logical PF id. In the case above, function 0 would\nhave a logical PF id of 0, and function 2 would have a logical PF id of\n1.\n\nCc: stable@dpdk.org\n\nUsing logical PF id can properly describe which slice of resources can\nbe used by a particular PF.\n\nSigned-off-by: Dan Nowlin <dan.nowlin@intel.com>\nSigned-off-by: Qi Zhang <qi.z.zhang@intel.com>\n---\n drivers/net/ice/base/ice_common.c | 19 +++++++++++++++++++\n drivers/net/ice/base/ice_flex_pipe.c | 2 +-\n drivers/net/ice/base/ice_type.h | 1 +\n 3 files changed, 21 insertions(+), 1 deletion(-)", "diff": "diff --git a/drivers/net/ice/base/ice_common.c b/drivers/net/ice/base/ice_common.c\nindex 641859f752..6004c95625 100644\n--- a/drivers/net/ice/base/ice_common.c\n+++ b/drivers/net/ice/base/ice_common.c\n@@ -2535,6 +2535,23 @@ ice_parse_func_caps(struct ice_hw *hw, struct ice_hw_func_caps *func_p,\n \tice_recalc_port_limited_caps(hw, &func_p->common_cap);\n }\n \n+/**\n+ * ice_func_id_to_logical_id - map from function id to logical pf id\n+ * @active_function_bitmap: active function bitmap\n+ * @pf_id: function number of device\n+ */\n+static int ice_func_id_to_logical_id(u32 active_function_bitmap, u8 pf_id)\n+{\n+\tu8 logical_id = 0;\n+\tu8 i;\n+\n+\tfor (i = 0; i < pf_id; i++)\n+\t\tif (active_function_bitmap & BIT(i))\n+\t\t\tlogical_id++;\n+\n+\treturn logical_id;\n+}\n+\n /**\n * ice_parse_valid_functions_cap - Parse ICE_AQC_CAPS_VALID_FUNCTIONS caps\n * @hw: pointer to the HW struct\n@@ -2552,6 +2569,8 @@ ice_parse_valid_functions_cap(struct ice_hw *hw, struct ice_hw_dev_caps *dev_p,\n \tdev_p->num_funcs = ice_hweight32(number);\n \tice_debug(hw, ICE_DBG_INIT, \"dev caps: num_funcs = %d\\n\",\n \t\t dev_p->num_funcs);\n+\n+\thw->logical_pf_id = ice_func_id_to_logical_id(number, hw->pf_id);\n }\n \n /**\ndiff --git a/drivers/net/ice/base/ice_flex_pipe.c b/drivers/net/ice/base/ice_flex_pipe.c\nindex fd98b3837d..8a6fc8a9a5 100644\n--- a/drivers/net/ice/base/ice_flex_pipe.c\n+++ b/drivers/net/ice/base/ice_flex_pipe.c\n@@ -3432,7 +3432,7 @@ static void ice_init_prof_masks(struct ice_hw *hw, enum ice_block blk)\n \tper_pf = ICE_PROF_MASK_COUNT / hw->dev_caps.num_funcs;\n \n \thw->blk[blk].masks.count = per_pf;\n-\thw->blk[blk].masks.first = hw->pf_id * per_pf;\n+\thw->blk[blk].masks.first = hw->logical_pf_id * per_pf;\n \n \tice_memset(hw->blk[blk].masks.masks, 0,\n \t\t sizeof(hw->blk[blk].masks.masks), ICE_NONDMA_MEM);\ndiff --git a/drivers/net/ice/base/ice_type.h b/drivers/net/ice/base/ice_type.h\nindex 56ee628f10..b1e03b10ff 100644\n--- a/drivers/net/ice/base/ice_type.h\n+++ b/drivers/net/ice/base/ice_type.h\n@@ -1132,6 +1132,7 @@ struct ice_hw {\n \tu8 revision_id;\n \n \tu8 pf_id;\t\t/* device profile info */\n+\tu8 logical_pf_id;\n \n \tu16 max_burst_size;\t/* driver sets this value */\n \n", "prefixes": [ "01/12" ] }
