💖 ice_ptp_lock(9) 💖

okay bestie, we're in the Kernel API Manual and this page is ice_ptp_lock(9) — tiny function, big lock energy. no cap. 💅

✨ NAME ✨

ice_ptp_lock — acquire the PTP global semaphore register lock.

🌸 SYNOPSIS 🌸

bool ice_ptp_lock (struct ice_hw *hw );

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW struct. that's the whole argument, bestie. 🫶

🦋 DESCRIPTION 🦋

Acquire the global PTP hardware semaphore lock. Returns true if the lock was acquired, false otherwise. literally the whole vibe.

The PFTSYN_SEM register sets the busy bit on read, returning the previous value. so here's the tea ☕: if software sees the busy bit cleared, that means this function acquired the lock — and the busy bit is now set. if software sees the busy bit set, it means that another function acquired the lock. 💀

when you're done, software must clear the busy bit with a write to release the lock for other functions. please don't gatekeep the lock, bestie. 🙈
