💅 qcom_scm_call_atomic(9) — Kernel API Manual ✨

Okay bestie, gather ’round — this is the Kernel API Manual page for qcom_scm_call_atomic(9), and no cap, every detail is staying. 🫶

🌸 NAME 🌸

qcom_scm_call_atomic — atomic variation of qcom_scm_call(), periodt. 💖

✨ SYNOPSIS ✨

The signature, exactly as it appears — no edits, no vibes-based renaming, fr fr:

int qcom_scm_call_atomic (struct device *dev , const struct
       qcom_scm_desc *desc , struct qcom_scm_res *res );

🎀 ARGUMENTS 🎀

• dev — device. That’s the whole note, bestie. 🫶
• desc — descriptor structure containing arguments and return values. It’s giving “the receipts and the results.” 💅
• res — structure containing results from the SMC/HVC call. This is where the tea comes back. ☕✨

🦋 DESCRIPTION 🦋

Okay so here’s the lowkey main character move: qcom_scm_call_atomic sends a command to the SCM and waits for the command to finish processing. That’s it. That’s the vibe. 💫

And the key little sparkle: this can be called in atomic context. So yeah, it’s literally the atomic variation, and that atomic-context line is the whole moment — no cap. 🔥
