ice_check_ph...p_ready_e810(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

ice_check_phy_tx_tstamp_ready_e810 — bestie, this one just checks the Tx memory status register 🎀

Oh and hey, we're in the Kernel API Manual today, not the normal user-facing one — different vibe, same queen energy 👑

✨ SYNOPSIS ✨

int ice_check_phy_tx_tstamp_ready_e810 (struct ice_hw *hw );

🫶 ARGUMENTS 🫶

  • hw — pointer to the HW struct. that's it. that's the whole argument list, she's low maintenance 💅

🌸 DESCRIPTION 🌸

okay so here's the tea, and it's honestly kind of iconic: the E810 devices do not have a Tx memory status register. like, at all. not a thing. it's giving "we forgot" but no, it's intentional 🦋

and ngl you should know this is intentionally different behavior from ice_get_phy_tx_tstamp_ready_e810, which always says that all bits are ready. so if you went in expecting these two to vibe the same way, they don't, and that was a whole choice ✨

this function gets called in cases where code will trigger interrupts if timestamps are waiting — so like, real consequences, not just for show 😭

and it should not be called for E810 hardware. fr fr. read that one twice, bestie 💀

🔥 RETURN 🔥

0.

that's it. that's the return value. zero. it said what it said 👑
