💅 i40e_dbg_dump_desc — a Kernel API Manual moment 🎀

okay so picture this: you're deep in the i40e driver, you're poking at debugfs, and you just have to dump a descriptor. bestie, that's literally what i40e_dbg_dump_desc is for. her whole job? handling the dump desc write into command datum. that's it, that's the gig. no cap. ✨

✨ NAME ✨

i40e_dbg_dump_desc — handles dump desc write into command datum 🫶

like… she takes your debugfs write and turns it into a descriptor dump. main character energy fr fr.

🦋 SYNOPSIS 🦋

void i40e_dbg_dump_desc (int cnt , int vsi_seid , int ring_id , int
desc_n , struct i40e_pf *pf , enum ring_type type );

six arguments. six. she's lowkey high-maintenance but she delivers 💅

🌸 ARGUMENTS 🌸

  • cnt — number of arguments that the user supplied. yeah, she's counting. someone has to keep track of how many things you handed her 🙈
  • vsi_seid — vsi id entered by user. your VSI, your seid, your problem 💖
  • ring_id — ring id entered by user. which ring are we looking at, bestie? 👀
  • desc_n — descriptor number entered by user. the actual descriptor you wanna peek at ✨
  • pf — the i40e_pf created in command write. iconic struct, no notes 🔥
  • type — enum describing whether ring is RX, TX or XDP. three whole vibes: receive, transmit, or XDP. pick one 🌈
ngl, every single one of these comes straight from the user typing stuff into the command write interface. you're the one supplying all of it. she's just the messenger 🧚
