📦 version 7.3.1, in nixpkgs unstable

NAME 💖

okay so this page is ve_spc_cpu_in_wfi(9) from the Kernel API Manual, and it checks whether the specified CPU is in WFI or not. That's the whole vibe. ✨

SYNOPSIS ✨

int ve_spc_cpu_in_wfi (u32 cpu , u32 cluster );

ARGUMENTS 🎀

  • cpu — the mpidr[7:0] bitfield describing CPU affinity level within cluster. yes bestie, it's a bitfield moment. 💅
  • cluster — the mpidr[15:8] bitfield describing cluster affinity level. another bitfield, iconic behavior. 🌸

RETURN 🦋

It returns non-zero if and only if the specified CPU is in WFI. that's the whole return tea, no cap. 💖

DESCRIPTION 🌸

Take care when interpreting the result of this function: a CPU might be in WFI temporarily due to idle, and is not necessarily safely parked. 😭

bestie, please do not take a WFI result as "this CPU is safely parked" — the page literally says take care when interpreting it, because it might just be idle temporarily. 💀

SEE ALSO 💅
