ve_spc_powerdown(9)

🌸 NAME 🌸

okay bestie, welcome to ve_spc_powerdown(9) — straight out of the Kernel API Manual ✨ and it's literally the function that enables/disables cluster powerdown 💅

✨ SYNOPSIS ✨

void ve_spc_powerdown (u32 cluster , bool enable );

🎀 ARGUMENTS 🎀

• cluster — mpidr[15:8] bitfield describing cluster affinity level
• enable — if true enables powerdown, if false disables it

💖 DESCRIPTION 💖

this is the function to enable/disable cluster powerdown, no cap 🫶

but bestie, listen: it is not protected by locking, because it might be used in code paths where normal cacheable locks are not working 😭 so locking must be provided by the caller to ensure atomicity — that's the whole vibe, iykyk 🔥

heads up: no built-in locking here. caller brings the locking if atomicity is the goal 💀
