ENUM PRU_TYPE(9)

💅 enum pru_type(9)

okay bestie, welcome to the Kernel API Manual — this one's short and sweet, it's the enum pru_type(9) page, and honestly it ate. It's just the PRU core type identifier, living over in ./include/linux. Let's get into it ✨

✨ SYNOPSIS ✨

enum pru_type {
    PRU_TYPE_PRU ,
    PRU_TYPE_RTU ,
    PRU_TYPE_TX_PRU ,
    PRU_TYPE_MAX

};

like, that's the whole vibe. four constants, no drama 🎀

🌸 CONSTANTS 🌸

• PRU_TYPE_PRU — this is the Programmable Real-time Unit. the OG, the main character 👑
• PRU_TYPE_RTU — the Auxiliary Programmable Real-Time Unit. the little helper bestie that shows up when you need it 🫶
• PRU_TYPE_TX_PRU — the Transmit Programmable Real-Time Unit. it transmits. it's giving communication icon 📡
• PRU_TYPE_MAX — literally just keep this one at the end, okay? it's the boundary marker, it holds the door 💅

no cap, PRU_TYPE_MAX is not a real type you go use — it sits at the end as the limit. respect the placement fr fr 🙈

go read those if you wanna go deeper, iykyk 📚💜

and that's the whole page, bestie — iconic, brief, no notes 🌈

sign-off szn: this one's from ./include/linux, dated October 2026, and yeah — it lives in the Kernel API Manual. periodt 💖
