ice_get_phy_tx_tstamp_ready(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ice_get_phy_tx_tstamp_ready β€” Kernel API Manual πŸŽ€

okay so bestie, welcome to the glow-up era of the kernel API docs ✨ this one lives in the Kernel API Manual, and honestly? it's giving "tiny function, big responsibilities." let's get into it 🫢


🌸 NAME 🌸

ice_get_phy_tx_tstamp_ready β€” Read PHY Tx memory status indication πŸ”₯

like, it literally just goes and asks the PHY "hey queen, are your Tx timestamps ready or not?"


πŸ¦‹ SYNOPSIS πŸ¦‹

int ice_get_phy_tx_tstamp_ready (struct ice_hw *hw , u8 block , u64
*tstamp_ready );

no cap, that's the whole signature. three things in, one int out πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • hw β€” pointer to the HW struct. your main character struct, the one with all the hardware lore 🏠
  • block β€” the timestamp block to check πŸ‘€ like, which block of timestamps are we vibe-checking rn
  • tstamp_ready β€” storage for the PHY Tx memory status information πŸ“¦ this is where the answer gets tucked away, so it better be pointing somewhere real

✨ DESCRIPTION ✨

Check the PHY for Tx timestamp memory status. that's the whole mission, bestie 🧚

This reports a 64 bit value which indicates which timestamps in the block may be captured. and here's the decoder ring, iykyk:

  • A set bit means the timestamp can be read. go off, read it πŸ‘‘
  • An unset bit means the timestamp is not ready and software should avoid reading the register. like, do NOT touch it, it's not ready for you yet πŸ™ˆ
fr fr though β€” an unset bit is not an invitation, it's a boundary. software should avoid reading the register. respect the bit 🚫
