ice_ptp_ts_irq(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_ptp_ts_irq — like, the PTP Tx timestamp IRQ handler, bestie

okay so this is ice_ptp_ts_irq(9) from section 9 of the Kernel API Manual — yes, the kernel API one, we're in the big leagues now 🎀

✨ NAME ✨

ice_ptp_ts_irq — the function that processes the PTP Tx timestamps while it's literally in IRQ context (interrupt vibes only, no sleeping, no napping, no blocking 😴🚫)

🌸 SYNOPSIS 🌸

irqreturn_t ice_ptp_ts_irq (struct ice_pf *pf );

🦋 ARGUMENTS 🦋

  • pf — the board private structure. that's it. that's the whole argument list, she's low-maintenance 💅

⭐ RETURN ⭐

so she returns an irqreturn_t, and it's giving two possible moods:

  • IRQ_WAKE_THREAD — returned when the Tx timestamp read has to be handled down in the bottom half of the interrupt. like, the top half says "not me, take it to the thread bestie" 🫶
  • IRQ_HANDLED — returned otherwise. handled it, done it, ate 💅
