ice_get_tx_topo_user_sel(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_get_tx_topo_user_sel — like, the kernel API manual, but make it make sense ✨

Okay bestie, so this one is a little function from the ice driver's manual page (section 9, the kernel API one, iykyk) and honestly? It's giving "one job, does it well." Let's get into it 🫶

🌸 NAME 🌸

ice_get_tx_topo_user_sel — literally just reads the user's choice out of flash 💾✨

🦋 SYNOPSIS 🦋

int ice_get_tx_topo_user_sel (struct ice_pf *pf , uint8_t *layers );

🎀 ARGUMENTS 🎀

  • pf — pointer to the pf structure. That's the party you're working with, bestie 💅
  • layers — the value that gets read from flash is gonna be saved right here. So this is where the tea lands 🍓

🔥 DESCRIPTION 🔥

So what it does is: it reads the user's preference for the Tx Scheduler Topology Tree from the PFA TLV. That's it. That's the whole vibe. No cap, it's just fetching your fave from flash so the rest of the driver knows what you picked 🌈

⭐ RETURN ⭐

Returns zero when the read was successful — slay 🎉 — and negative values otherwise 😭 (so like, if you see a negative number, the read did not eat).

💜 SEE ALSO 💜

Heads up bestie 🫶 the source path in the original shows up truncated as ./drivers/net/ethernet/intel/i... before the date — that's just the page footer doing its thing, not a typo on your end 💀
