rpmh_rsc_invalidate(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this is literally the page for rpmh_rsc_invalidate, and it’s giving “short but important” energy.

---

🌸 NAME 🌸

rpmh_rsc_invalidate — Invalidate sleep and wake TCSes. periodt 💖

---

✨ SYNOPSIS ✨

call it exactly like this, no cap:

void rpmh_rsc_invalidate (struct rsc_drv *drv );

---

🫶 ARGUMENTS 🫶

• drv — The RSC controller. that’s the whole argument, bestie 🎀

---

🔥 DESCRIPTION 🔥

okay so real talk: the caller must ensure that no other RPMH actions are happening when this function is called. because otherwise, the device may immediately become used again even before this function exits. like, it can come right back and be used again before this function is even done. no cap, that’s the caveat 💀

⚠️ so yeah: caller’s responsibility. keep the RPMH action vibe check clean when you call this, or the device may immediately become used again even before this function exits.
