🌸 t4_get_vpd_params(9) — the Kernel API Manual glow-up 🌸

okay bestie, welcome to section 9 of the Kernel API Manual — yes, the Kernel API Manual, we're in the big leagues now 💅 This little cutie is t4_get_vpd_params, and she's here to read your VPD params and pull out the Core Clock. iconic behavior, honestly.

💖 NAME 💖

t4_get_vpd_params — read VPD parameters & retrieve Core Clock ✨

🦋 SYNOPSIS 🦋

int t4_get_vpd_params (struct adapter *adapter , struct vpd_params *p );

🎀 ARGUMENTS 🎀

  • adapter — the adapter we're gonna read from, bestie. that's the whole vibe check right there.
  • p — the spot where the parameters get stored. like, this is where the lore lands 📥

🌈 DESCRIPTION 🌈

so basically: this function reads the card parameters that are stored in the VPD EEPROM and then retrieves the Core Clock. two-for-one, we love a multitasker 🫶

⚠️ okay but real talk — this can only be called after a connection to the firmware is established. no firmware connection, no params. don't come for her before she's ready 😭

👑 SEE ALSO 👑

first up, the actual home of the code — Kernel file ./drivers/net/ethernet/chelsio/cxgb4/t4_hw.c 📁

and now the extended universe, in order, no skips, no cap:

that's the whole friend group, every single one of them 💀✨

okay and before you go — this page is brought to you by the source/path ./drivers/net/ethernet/chelsio... (the drivers directory said "you get a truncated path, as a treat") and it's dated October 2026. so go forth, read those VPD params, get that Core Clock, and slay 💅👑
