✨ qcom_pbs_trigger_event(9) ✨

okay bestie, this is a page straight out of the Kernel API Manual and it's about qcom_pbs_trigger_event — literally the function that kicks off the PBS RAM sequence 🎀

💖 NAME 💖

qcom_pbs_trigger_event — trigger the PBS RAM sequence, no cap 🦋

---

🌸 SYNOPSIS 🌸

int qcom_pbs_trigger_event (struct pbs_dev *pbs , u8 bitmap );

🧚 ARGUMENTS 🧚

• pbs — pointer to the PBS device 👑
• bitmap — the bitmap, yes that's it, that's the whole description, it's giving minimal and honestly? iconic 💅

🦋 DESCRIPTION 🦋

so this function is the main character: it's used to trigger the PBS RAM sequence to be executed by the client driver. it's giving "press play on the whole operation" energy ✨

the PBS trigger sequence goes like this, step by step, iykyk:

1. setting the PBS sequence bit in PBS_CLIENT_SCRATCH1 🎀
2. initiating the SW PBS trigger 🔥
3. checking the equivalent bit in PBS_CLIENT_SCRATCH2 for the completion of the sequence 👀
4. if PBS_CLIENT_SCRATCH2 == 0xFF, the PBS sequence failed to execute 💀

bestie pls note step 4 — that 0xFF is the fail signal, so if you see it, the sequence did NOT slay 😭

⭐ RETURN ⭐

• 0 on success 💖
• < 0 on failure 🙈
