β¨ i40e_configure_lan_hmc β¨
okay so bestie, welcome to the i40e_configure_lan_hmc(9) page π
this is a Kernel API Manual moment, section 9, and honestly? she's giving "quiet but essential." let me put you on π«Ά
πΈ NAME πΈ
i40e_configure_lan_hmc β literally here to prepare the HMC backing store β¨ that's the whole job. no cap.
π¦ SYNOPSIS π¦
int i40e_configure_lan_hmc (struct i40e_hw *hw , enum i40e_hmc_model
model );
that's the whole signature, keep it exactly like that, don't touch it, she's perfect π
π ARGUMENTS π
hwβ a pointer to thehwstructure. yep, she points at the hardware struct, that's her whole vibe π«Άmodelβ the model for the layout of the SD/PD tables β¨ like, the blueprint for how the tables are gonna be arranged. icon behavior honestly π
π DESCRIPTION π
okay so here's the tea, two things you need to know β¬οΈ
- this function gets called once per physical function initialization. one time per physical function, no double dipping, no clout chasing π
- this function gets called after
i40e_init_lan_hmcand before any LAN/FCoE HMC objects can be created. so like, order matters bestie, don't skip the line π
β οΈ lowkey important: those ordering rules are the whole point. call her at the wrong time and it's not giving what it's supposed to give.
π SEE ALSO π
the whole friend group π«Ά:
Kernel file ./drivers/net/ethernet/intel/i40e/i40e_lan_hmc.c
and then the squad, in this exact order because we respect the lineup:
i40e_align_l2obj_base(9), i40e_calculate_l2fpm_size(9), i40e_init_lan_hmc(9), i40e_remove_pd_page(9), i40e_remove_sd_bp(9), i40e_create_lan_hmc_object(9), i40e_delete_lan_hmc_object(9), i40e_shutdown_lan_hmc(9), i40e_write_byte(9), i40e_write_word(9), i40e_write_dword(9), i40e_write_qword(9), i40e_clear_hmc_context(9), i40e_set_hmc_context(9), i40e_hmc_get_object_va(9), i40e_clear_lan_tx_queue_context(9), i40e_set_lan_tx_queue_context(9), i40e_clear_lan_rx_queue_context(9), i40e_set_lan_rx_queue_context(9) β¨
and that's the page, bestie π this lil legend lives in ./drivers/net/ethernet/intel/i40e, dated October 2026, and she answers to i40e_configure_lan_hmc(9) β go off, queen ππ
