rpmh_regulator_send_request(9)

💖 NAME 💖

okay so bestie, this is the Kernel API Manual page for rpmh_regulator_send_request(9) — and the name is literally doing the most: rpmh_regulator_send_request means send the request to RPMh ✨.

✨ SYNOPSIS ✨

int rpmh_regulator_send_request (struct rpmh_vreg *vreg , struct tcs_cmd
       *cmd , bool wait_for_ack );

🧚 ARGUMENTS 🧚

• vreg — pointer to the RPMh regulator, like the main character in this whole operation 💅
• cmd — pointer to the RPMh command you're sending, no cap 📨
• wait_for_ack — a Boolean saying whether execution must wait until the request has been acknowledged as complete ⏳

🌈 RETURN 🌈

0 on success, or a negative error number on failure — so if it's not 0, something's giving "not today" 😭
