ENUM MHI_CH_TYPE(9)

💅 enum mhi_ch_type(9) — straight from the Kernel API Manual, bestie

okay so picture this: you're in the kernel API manual (yes, that one), and you've stumbled onto enum mhi_ch_type. It's literally just the vibe check for MHI channels — like, what kind of channel even are you? Let's get into it 🫶

✨ NAME ✨

enum mhi_ch_type — channel types, periodt 💅

---

🦋 SYNOPSIS 🦋

enum mhi_ch_type {
    MHI_CH_TYPE_INVALID ,
    MHI_CH_TYPE_OUTBOUND ,
    MHI_CH_TYPE_INBOUND ,
    MHI_CH_TYPE_INBOUND_COALESCED

};

---

🎀 Constants 🎀

girl, there are exactly four of them and they each have main character energy in their own way:

• MHI_CH_TYPE_INVALID — the "no thoughts, head empty" option 💀 it's the invalid channel type, i.e. not a real one.
• MHI_CH_TYPE_OUTBOUND — outbound channel to the device 🚀 your stuff, heading to the device.
• MHI_CH_TYPE_INBOUND — inbound channel from the device 🌸 the device's stuff, coming back to you.
• MHI_CH_TYPE_INBOUND_COALESCED — the icon, the moment 👑 this is a coalesced channel — it lets the device combine multiple packets and send them as a single large packet to reduce CPU consumption. highkey efficient, ngl.
