πŸ’… ice_ptp_exec_tmr_cmd β€” Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual entry for ice_ptp_exec_tmr_cmd πŸŽ€ this one is short, it's sweet, and it's lowkey the "GO" button for the whole PTP timer situation.


🌸 NAME 🌸

ice_ptp_exec_tmr_cmd β€” Execute all prepared timer commands πŸ‘‘

like... all of them. at once. synchronously. no cap 🫢


✨ SYNOPSIS ✨

void ice_ptp_exec_tmr_cmd (struct ice_hw *hw );

πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to HW struct. literally just the hardware struct pointer, she's the main character here πŸ’œ

πŸ’– DESCRIPTION πŸ’–

so what she does is: write the SYNC_EXEC_CMD bit to the GLTSYN_CMD_SYNC register, and then flush the write immediately ⚑

that immediate flush is the whole vibe β€” it's what triggers the hardware to begin executing all of the source and PHY timer commands synchronously 🌈 like a little starting pistol for your timers, periodt.

no waiting around, no "I'll get to it later" energy. the write goes out, the hardware hears it, everybody moves in sync πŸ’…


🌟 SEE ALSO 🌟

the kernel file for this lives at ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c πŸ“ β€” go read her, she's iconic.

whew. okay. that's the whole squad πŸ’€πŸ’–


fr fr though β€” if you only remember one thing: SYNC_EXEC_CMD β†’ GLTSYN_CMD_SYNC, flush immediately, everything runs in sync. she's a simple girl with a big job 🧚

okay that's the page!! mwah πŸ’‹ this one came from ./drivers/net/ethernet/intel/ice, dated October 2026, and her full government name is ice_ptp_exec_tmr_cmd(9) πŸŽ€ go forth and sync your timers bestie β­πŸ’œ
