ice_save_agg_tc_bitmap(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_save_agg_tc_bitmap — like, the aggregator TC bitmap saver (kernel API manual, section 9, bestie)

okay so real talk, this one lives in the Kernel API Manual, section 9, and it's called ice_save_agg_tc_bitmap(9). Say it with me: it saves the aggregator TC bitmap. That's the whole job. Slay. ✨

🌸 SYNOPSIS 🌸

int ice_save_agg_tc_bitmap (struct ice_port_info *pi , u32 agg_id ,
unsigned long *tc_bitmap );

Three args, one int coming back at you. Iconic signature, no notes. 🫶

🎀 ARGUMENTS 🎀

  • pi — the port information structure. Your whole port's vibe, basically.
  • agg_id — the aggregator ID. Which aggregator we're talking about, iykyk.
  • tc_bitmap — an 8 bits TC bitmap. Eight bits. Not seven, not nine. Eight. 💅

💖 DESCRIPTION 💖

So this function saves the aggregator TC bitmap. That's it, that's the function. Lowkey minimal, highkey important. 🦋

⚠️ okay bestie, listen — you need to call this one with the scheduler lock held. Not optional. Not "eh, probably fine." Held. Periodt. 🔒

👑 SEE ALSO 👑

the kernel file, first of all, because that's where the source lives:

./drivers/net/ethernet/intel/ice/ice_sched.c

and then literally the entire ice scheduler extended family showed up to the group chat, fr fr:

that's the whole roster, bestie. no cap, I counted. 🌈

anyway the source dir is ./drivers/net/ethernet/intel/ice, this page is dated October 2026, and it's filed under ice_save_agg_tc_bitmap(9). drink water, hold the scheduler lock, bye bestie 💜🧚‍♀️
