scmi_xfer_raw_channel_get(9)

💅 scmi_xfer_raw_channel_get(9) 💅

okay so welcome to the Kernel API Manual, bestie — this is the page for scmi_xfer_raw_channel_get, and it’s giving very specific-channel-reference energy. 💖

🌸 NAME 🌸

scmi_xfer_raw_channel_get — helper to get a reference to the proper channel to use for a specific protocol_id Raw transaction. Periodt. ✨

✨ SYNOPSIS ✨

struct scmi_chan_info * scmi_xfer_raw_channel_get (const struct
       scmi_handle *handle , u8 protocol_id );

🎀 ARGUMENTS 🎀

• handle — pointer to the SCMI entity handle. 🫶
• protocol_id — identifier of the protocol. 💫

🦋 DESCRIPTION 🦋

Note that in a regular SCMI stack, usually, a protocol has to be defined in the DT to have an associated channel and be usable. But in Raw mode any protocol in range is allowed, re-using the Base channel, so as to enable fuzzing on any protocol without the need of a fully compiled DT. No cap. 🔥

💜 RETURN 💜

A reference to the channel to use, or an ERR_PTR. That’s the whole return vibe. 😭
