scx_missing_caps(9)

💖 NAME 💖

okay so welcome to scx_missing_caps(9), straight outta the Kernel API Manual ✨ this one is literally “the caps in @needed that @sch lacks on @cpu” — that’s the whole name, bestie, and it ate.

🎀 SYNOPSIS 🎀

u64 scx_missing_caps (struct scx_sched *sch , s32 cpu , u64 needed );

✨ ARGUMENTS ✨

• sch — the sched to test. yes, this is the one getting the vibe check.
• cpu — the cpu to test on. location check, basically.
• needed — bitmask of SCX_CAP_* values. the little list of caps we care about.

🦋 DESCRIPTION 🦋

Return the caps in needed that sch lacks for cpu, and 0 if it holds them all. no cap left behind, periodt. if sch already has every single one, you get 0; otherwise you get the missing caps. iconic behavior tbh.
