ipr_ioafp_pageC4_inquiry(9)

Okay bestie, this is ipr_ioafp_pageC4_inquiry(9) from the Kernel API Manual, and it’s giving “tiny kernel helper with one very specific job” energy. Let’s get into it 💅✨

🎀 NAME 🎀

ipr_ioafp_pageC4_inquiry — Send a Page 0xC4 Inquiry to the adapter.

One job, one vibe: send that Page 0xC4 Inquiry to the adapter. Periodt.

✨ SYNOPSIS ✨

Here’s the signature, exactly as written, because we do not freestyle kernel signatures in this group chat:

int ipr_ioafp_pageC4_inquiry (struct ipr_cmnd *ipr_cmd );

That’s it. That’s the whole call 🫶

🦋 ARGUMENTS 🦋

• ipr_cmd — ipr command struct. This is the command struct the function gets handed; keep the spelling exactly as shown, bestie.

💖 DESCRIPTION 💖

This function sends a Page 0xC4 inquiry to the adapter to retrieve software VPD information.

Like, it’s literally the “go ask the adapter for its software VPD info” step ✨

Return value: IPR_RC_JOB_CONTINUE / IPR_RC_JOB_RETURN

No cap, those are the return values you’re looking at.

🌈 SEE ALSO 🌈
