i40e_write_qword(9)

💅 i40e_write_qword — the i40e_write_qword(9) kernel API page, bestie edition

okay so this is a kernel API manual page for i40e_write_qword(9), from the i40e section of the kernel docs (section 9, kernel API, iykyk). Basically it's the "replace HMC context qword" girlie. Let's get into it ✨

✨ NAME ✨

i40e_write_qword — replace HMC context qword 💫

🎀 SYNOPSIS 🎀

void i40e_write_qword (u8 *hmc_bits , struct i40e_context_ele *ce_info ,
u8 *src );

like. that's the whole signature. void return, three args, slay. no cap, that's literally it 🫶

🌸 ARGUMENTS 🌸

• hmc_bits — pointer to the HMC memory. that's the destination bestie, the actual bytes you're writing into 💖
• ce_info — a description of the struct to be read from. it's the little info card that tells you what you're working with, okay? 🎀
• src — the struct to be read from. the source. the origin. the main character of this whole operation fr 👑

ngl, ce_info and src have the exact same description in the original page — yes, i noticed too, and no, i'm not changing it. facts are facts 💀

🦋 SEE ALSO 🦋

the kernel file where this lives:

Kernel file ./drivers/net/ethernet/intel/i40e/i40e_lan_hmc.c

and the whole friend group, all of them, in order, no one left out 🫶:

• i40e_align_l2obj_base(9)
• i40e_calculate_l2fpm_size(9)
• i40e_init_lan_hmc(9)
• i40e_remove_pd_page(9)

like okay, i40e_write_byte, i40e_write_word, i40e_write_dword, and now i40e_write_qword — the size family ate and left no crumbs 🔥
