ice_check_ph...ready_eth56g(9)

💅 ice_check_phy_tx_tstamp_ready_eth56g — like, the whole manual page, bestie

okay so this is ice_check_ph...ready_eth56g(9) from the Kernel API Manual, section 9, and honestly? it's a little baddie of a function. the way it just... checks Tx memory status for all the ports at once? main character energy fr fr. 🎀

Let's get into it. ✨

🌸 NAME 🌸

ice_check_phy_tx_tstamp_ready_eth56g — checks the Tx memory status for every single port, no port left behind, periodt. 💅

🦋 SYNOPSIS 🦋

int ice_check_phy_tx_tstamp_ready_eth56g (struct ice_hw *hw );

that's it. one argument. clean. iconic. 🔥

⭐ ARGUMENTS ⭐

hw — pointer to the HW struct. that's literally the whole vibe, she just wants the hardware struct and she'll handle the rest 💖

✨ DESCRIPTION ✨

okay so here's the tea 🍵 — this function goes and checks PHY_REG_TX_MEMORY_STATUS for all of the ports. every last one of them. group chat, everyone tagged. 🫶

and a set bit? that means a timestamp is waiting there. like, it's in the queue, it's ready, it's giving "pick me" energy. 🌈

👑 RETURN 👑

so what does she give you back?

1 if any port has at least one timestamp ready bit set — yes, even just one port, she counts it, no gatekeeping 🙈
0 otherwise — nothing's waiting, ghost town, no timestamps, rest well bestie 💀
a negative error code if she's unable to read the bitmap — like she tried to read it and the bitmap just wasn't giving 😭

ngl the "negative error code" case is your reminder to actually check the return value before you assume everything's fine. she WILL tell you something went wrong, bestie, don't ignore her 💅
