💅 geni_se_resources_init(9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel API manual page, it's called geni_se_resources_init(9), and it's literally about waking up a GENI SE device's whole resource situation. let's get into it ✨

---

✨ NAME ✨

geni_se_resources_init — the girl whose entire job is initializing resources for a GENI SE device. she's the setup bestie. 🎀

---

🌸 SYNOPSIS 🌸

int geni_se_resources_init (struct geni_se *se );

---

💖 ARGUMENTS 💖

• se — a pointer to the geni_se structure, i.e. the actual GENI SE device being represented. that's the main character right there 👑

---

🦋 DESCRIPTION 🦋

so what does this function actually do? it initializes all the various resources the GENI Serial Engine (SE) device needs to function, and honestly it's giving project manager energy:

• it handles the clock resources — that's the core clock and the SE clock, both of them, no skipping 🕐
• it sorts out the interconnect paths for communication
• it retrieves the optional and mandatory clock resources (yes, both kinds, she's thorough)
• it adds an OF-based operating performance point (OPP) table
• it sets up the interconnect paths with default bandwidths
• and to top it all off, it sets a flag called has_opp to indicate whether OPP support is actually available for the device 💅

like, she does a lot. no cap.

🔥 RETURN 🔥

• 0 on success 🎉
• a negative errno on failure 😭
