💜 ice_vc_isvalid_ring_len(9) 💜

okay so first things first, this page lives in the Kernel API Manual (that's the manual name, bestie, that's where you'll find it) and it's all about one tiny little function that does one tiny little vibe check. she's small but she's important, iykyk 🎀

✨ NAME ✨

ice_vc_isvalid_ring_len — and that's it. that's the whole name section. no description, no little tagline, just her name sitting there like main character energy. honestly? iconic. she said "my work speaks for itself" 💅

🌸 SYNOPSIS 🌸

bool ice_vc_isvalid_ring_len (u16 ring_len );

so she takes one u16 and hands you back a bool. yes/no. valid/not valid. slay or don't slay. that's the whole deal 🦋

🎀 ARGUMENTS 🎀

  • ring_len — the length of the ring. that's the whole description. it's the ring length, bestie, the length of the ring. she's not gonna elaborate ✨

💖 DESCRIPTION 💖

okay so what does she actually do? she checks whether the ring count is valid, and "valid" here means one (1) of exactly two things:

  • it's a multiple of ICE_REQ_DESC_MULTIPLE, or
  • it's zero

that's it. that's the whole check. zero is fine, multiples of ICE_REQ_DESC_MULTIPLE are fine, everything else gets a hard no 🙈 literally just a vibe check for your ring length, no cap 🔥

🫶 SEE ALSO 🫶

like all her besties, she's in the kernel file ./drivers/net/ethernet/intel/ice/virt/queues.c and she runs with a whole friend group:

go read them all, they're all slaying in their own little lanes 🌈

this page's source/version line is ./drivers/net/ethernet/intel/i... and it's dated October 2026 — so like, mark your calendars, and if you ever need her again she's filed under ice_vc_isvalid_ring_len(9) 💜✨ no cap, periodt. 🧚‍♀️
