geni_icc_set_bw_ab(9)

💅 geni_icc_set_bw_ab — the kernel API manual, but make it make sense

okay so bestie, we're in the kernel API manual ✨ — this page lives in the geni_icc_set_bw_ab section (that's section 9, the kernel API one), and it's all about setting average bandwidth on every ICC path and then actually applying it. yes girl, all of them. 🎀

---

✨ NAME ✨

geni_icc_set_bw_ab — Set average bandwidth for all ICC paths and apply 💫

---

🌸 SYNOPSIS 🌸

int geni_icc_set_bw_ab (struct geni_se *se , u32 core_ab , u32 cfg_ab ,
u32 ddr_ab );

like, it takes a struct geni_se *, three u32s, and hands you back an int. that's the whole vibe check. 🦋

---

🫶 ARGUMENTS 🫶

• se — pointer to the concerned serial engine. that's the main character right there 👑
• core_ab — average bandwidth in kBps for the GENI_TO_CORE path 💖
• cfg_ab — average bandwidth in kBps for the CPU_TO_GENI path 🌸
• ddr_ab — average bandwidth in kBps for the GENI_TO_DDR path 🦋

note the units bestie, they're kBps for all three. do not come at me with bytes per second. 😭

---

🔥 DESCRIPTION 🔥

So what it does is sets bandwidth values for all the ICC paths, and then applies them. that's it, that's the function. slay. ✨

but the tea ☕: the DDR path is optional, and it only gets set if it exists. so if there's no DDR path, it just… doesn't set it. no cap, it's conditional like that. 💅

---

⭐ RETURN ⭐

• 0 on success 🎉 literally the best feeling
• a negative error code on failure 💀 (yes, negative. don't @ me)
