scx_rescue_charge(9)

💖 NAME 💖

scx_rescue_charge — charge the rescuee’s runtime, bestie. (Yup, this is scx_rescue_charge(9) from the Kernel API Manual, and it’s giving very specific scheduler energy. 💅✨)

✨ SYNOPSIS ✨

void scx_rescue_charge (struct rq *rq , s64 delta_exec );

🎀 ARGUMENTS 🎀

• rq — the rq that the rescuee is running on. That’s the one, bestie.
• delta_exec — the runtime being charged. Literally the amount going on the tab. 💸

🦋 DESCRIPTION 🦋

It also ends the rescue once the admitted slice has been served in full. Ending on served time rather than slice exhaustion bounds both the rescue and the charging when a scheduler extends the rescuee’s slice. No cap — that timing detail is doing main character work. 👑
