srpt_get_ioc(9)

🌸 srpt_get_ioc — NAME ✨

okay so bestie, srpt_get_ioc literally writes the IOControllerprofile to a management datagram 💅 that's the whole vibe, no cap.

🎀 SYNOPSIS 🎀

void srpt_get_ioc (struct srpt_port *sport , u32 slot , struct ib_dm_mad
*mad );

💖 ARGUMENTS 💖

• sport — the HCA port the MAD came in through 🫶 like, that's the entry point, okay?
• slot — the slot number that got specified in the DM_ATTR_IOC_PROFILE query ✨
• mad — the datagram that's gonna get sent back as the response to DM_ATTR_IOC_PROFILE 💌 it's the reply, it's the moment, it's giving main character energy

🦋 DESCRIPTION 🦋

sooo this is where you go read the receipts 📖 go look at section 16.3.3.4 IOControllerProfile in the InfiniBand Architecture Specification — that's the lore, bestie. also peep section B.7, table B.7 in the SRP r16a document. iykyk 👑
