💌 psp_send_platform_access_msg(9) — Kernel API Manual 🎀

okay bestie, welcome to the Kernel API Manual, and today's main character is psp_send_platform_access_msg 💅 (the header lowkey abbreviates it as psp_send_pla...m_access_msg(9) because even manpage titles get tired, iykyk).

✨ NAME ✨

psp_send_platform_access_msg — send a message to control platform features 🦋

🌸 SYNOPSIS 🌸

int psp_send_platform_access_msg (enum psp_platform_access_msg , struct
psp_request *req );

🎀 ARGUMENTS 🎀

  • psp_platform_access_msg — -- undescribed -- 🙈 (yes literally, the docs just say undescribed, we are NOT going to make something up, that would be fake news)
  • req — -- undescribed -- 😭 (same energy, no description in the source, so no cap from me)
fr fr, both of these are listed as -- undescribed -- in the original. That's the whole vibe check on them. 💀

💖 DESCRIPTION 💖

So this function is intended to be used by drivers outside of ccp to communicate with the platform 🫶. That's the whole gig. It's the little messenger that lets those outside drivers talk to the platform, iconic behaviour honestly ✨.

🔥 RETURN 🔥

the tea on what you get back ☕:

  • 0 — success 👑 slay
  • -EBUSY — mailbox in recovery or in use 😮‍💨 (it's going through something, give it a sec)
  • -ENODEV — driver not bound with PSP device 💀 not me showing up uninvited
  • -ETIMEDOUT — request timed out ⏰ the request literally ghosted you
  • -EIO — unknown error (see kernel log) 🌈 mysterious and unbothered, go check the log bestie
