ipa_endpoint_replenish(9)

🌸 NAME 🌸

ipa_endpoint_replenish — Replenish endpoint receive buffers 💖 and yes bestie, this is straight outta the Kernel API Manual 🫶✨

✨ SYNOPSIS ✨

void ipa_endpoint_replenish (struct ipa_endpoint *endpoint );

🫶 ARGUMENTS 🫶

• endpoint — the endpoint that's getting replenished, periodt 🎀

💖 DESCRIPTION 💖

okay so the IPA hardware can hold a fixed number of receive buffers for an RX endpoint, and that number is based on the number of entries in the underlying channel ring buffer 🦋 no cap, that's the whole vibe check.

if an endpoint's "backlog" is non-zero, it tells you how many more receive buffers can be supplied to the hardware 👑 literally the receipts.

and heads up: replenishing for an endpoint can be disabled, and in that case buffers are not queued to the hardware 💀 so yeah, that's the important part, iykyk.
