ti_sci_get_one_xfer(9)

💖 ti_sci_get_one_xfer(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is literally all about ti_sci_get_one_xfer, and yes, it's giving “allocate one message” main character energy. 🎀✨

🌸 NAME 🌸

ti_sci_get_one_xfer — Allocate one message

✨ SYNOPSIS ✨

struct ti_sci_xfer * ti_sci_get_one_xfer (struct ti_sci_info *info , u16
       msg_type , u32 msg_flags , size_t tx_message_size , size_t
       rx_message_size );

💅 ARGUMENTS 💅

• info — Pointer to SCI entity information.
• msg_type — Message type.
• msg_flags — Flag to set for the message.
• tx_message_size — transmit message size.
• rx_message_size — receive message size.

🦋 DESCRIPTION 🦋

This is the helper function that the various command functions exposed to clients of this driver use when they need to allocate a message traffic event. She's a team player like that. 💖

Depending on pending requests already in the system for the SCI entity, this function can sleep 😴 — yes, literally. It also holds a spinlock to maintain integrity of internal data structures.

bestie, it can sleep and it holds a spinlock — both facts are right there in the description, so respect the vibe. 🫶

🔥 RETURN 🔥

It returns 0 if all went fine 🎉, otherwise you get the corresponding error 😭.
