💅 zynqmp_pm_get_node_status(9) — Kernel API Manual core 💖

okay bestie, gather round. this is the Kernel API Manual page for zynqmp_pm_get_node_status, and it's literally the PM call to request a node's current power state. no cap, it's giving “power-status check, but make it kernel.” ✨

🌸 NAME 🌸

zynqmp_pm_get_node_status — PM call to request a node's current power state.

✨ SYNOPSIS ✨

int zynqmp_pm_get_node_status (const u32 node , u32 *const status , u32
*const requirements , u32 *const usage );

Lowkey that line break is exactly how the manpage serves it, and we're keeping it. 🫶

🎀 ARGUMENTS 🎀

• node — ID of the component or sub-system in question. It's the “who are we checking?” param. 💅
• status — Current operating state of the requested node. The main-character output, periodt. 👑
• requirements — Current requirements asserted on the node, used for slave nodes only. Bestie, that “slave nodes only” is important. 🎯
• usage — Usage information, used for slave nodes only. This one comes with its own little enum moment:
  • PM_USAGE_NO_MASTER — No master is currently using the node.
  • PM_USAGE_CURRENT_MASTER — Only requesting master is currently using the node.
  • PM_USAGE_OTHER_MASTER — Only other masters are currently using the node.
  • PM_USAGE_BOTH_MASTERS — Both the current and at least one other master is currently using the node.

💖 RETURN 💖

Returns status, either success or error+reason. That's the whole vibe: success or error+reason. No in-between. 💀
