zynqmp_pm_get_chipid(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… zynqmp_pm_get_chipid(9) β€” like, the whole glow-up

okay so bestie, welcome to the Kernel API Manual ✨ This one's about zynqmp_pm_get_chipid(9), and no cap, it's short but it's iconic. Let's get into it πŸŽ€


🌸 NAME 🌸

zynqmp_pm_get_chipid β€” Get silicon ID registers πŸ”₯

Like, it literally goes and grabs the silicon ID registers for you. That's the whole vibe. iykyk πŸ’…


πŸ¦‹ SYNOPSIS πŸ¦‹

int zynqmp_pm_get_chipid (u32 *idcode , u32 *version );

so you call it, you hand it two pointers, and it returns an int (which is the status, we'll get to that πŸ‘€). The spacing in there is exactly as the manpage says it β€” do not come for me 🫢


✨ ARGUMENTS ✨

Two args, both of them pointers to u32, both of them literally the whole point of the function:

  • idcode β€” the IDCODE register πŸ’– Like, this is where the IDCODE lands.
  • version β€” the version register πŸŽ€ Yeah. The version goes here.

that's it, that's the arguments, and yes they're both required β€” you're passing pointers in, so no sneaky NULL-ish games being described here, mkay? πŸ™ˆ


πŸ’œ RETURN πŸ’œ

So the function returns the status of the operation, AND it drops the idcode and version registers into idcode and version respectively. Like a little two-for-one deal πŸ”₯ Status out the return, data out the pointers. Obsessed, honestly.


🌈 SEE ALSO 🌈

okay this is the part where the manpage just absolutely spills β€” it's giving main character energy, it's giving "I know everyone at this party" πŸ’€ Every one of these, no skipping, no summarising, periodt:

Kernel file ./drivers/firmware/xilinx/zynqmp.c and friends:

And the directory it all lives in: ./drivers/firmware/xilinx 🧚


ngl bestie, that SEE ALSO list is longer than my attention span, but we got through it together πŸ«ΆπŸ’–
