✨ zynqmp_ipi_setup(9) ✨

Okay bestie, welcome to the Kernel API Manual πŸ’– β€” this one's about the ZynqMP IPI mailbox setup, and yes it's as niche as it sounds but we're gonna slay it together.


🌸 NAME 🌸

zynqmp_ipi_setup β€” set up IPI Buffers for classic flow πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

int zynqmp_ipi_setup (struct zynqmp_ipi_mbox *ipi_mbox , struct
       device_node *node );

πŸ’… ARGUMENTS πŸ’…

  • ipi_mbox β€” pointer to IPI mailbox private data structure 🫢
  • node β€” IPI mailbox device node ✨

πŸ‘‘ DESCRIPTION πŸ‘‘

So here's the vibe: this is what you use to set up IPI Buffers for ZynqMP SOC if the user wishes to use the classic driver usage model on new SOC's that only have buffered IPIs. Like, new hardware, old-school flow β€” it's giving legacy-but-make-it-cute πŸ’€

⚠️ Okay important, no cap: bufferless IPIs and mixed usage of buffered and bufferless IPIs are not supported with this flow. Not a single one. Don't try it πŸ™ˆ

This will be invoked with compatible string "xlnx,zynqmp-ipi-mailbox" πŸ”₯


⭐ RETURN ⭐

0 for success, negative value for failure β€” literally the simplest vibe check ever 😭
