💅 __zynqmp_clock_get_topology(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little internal helper coming at you straight out of the kernel, and honestly? it's giving "backstage pass" energy. no cap.

🌸 NAME 🌸

__zynqmp_clock_get_topology — the function that grabs the topology data of a clock out of the firmware response data 🎀 lowkey the whole point of the function, and it ate.

🦋 SYNOPSIS 🦋

int __zynqmp_clock_get_topology (struct clock_topology *topology ,
       struct topology_resp *response , u32 *nnodes );

three args, one int, that's the vibe 💜

✨ ARGUMENTS ✨

  • topology — Clock topology. this is where the topology info lands, main character energy fr 🫶
  • response — Clock topology data received from firmware. yes, the firmware handed it over, and yes, we're reading it 👑
  • nnodes — Number of nodes. literally just how many nodes we're dealing with 🔥

💀 RETURN 💀

0 on success, else error+reason — so like, if it's not 0, something went sideways and the reason comes with it 😭 check it, don't ignore it, periodt.
