ice_vsi_determine_xdp_res(9)

💖 NAME 💖

okay bestie, welcome to the ice_vsi_determine_xdp_res(9) page from the Kernel API Manual. This function is literally called ice_vsi_determine_xdp_res, and its whole job is: figure out how many Tx qs can XDP have. No cap. ✨

✨ SYNOPSIS ✨

int ice_vsi_determine_xdp_res (struct ice_vsi *vsi );

🫶 ARGUMENTS 🫶

• vsi — the VSI to determine the count of XDP Tx qs. That's the whole argument, and it's iconic. 💅

🧚 DESCRIPTION 🧚

so here's the vibe check: this function returns 0 if the Tx qs count is higher than at least half of the CPU count. If it's not, you get -ENOMEM instead. periodt. 😭

bestie, keep that exact condition in mind: higher than at least half of the CPU count is the slay case, and -ENOMEM is the other case. fr fr. 🫶
