dcn60_populate_clk_table(9)

✨ dcn60_populate_clk_table ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about one function: dcn60_populate_clk_table. it's giving "niche kernel lore" and honestly? we're obsessed 🎀

---

💅 NAME

dcn60_populate_clk_table — populate clock table from DAL init table. that's it, that's the whole vibe. 🦋

---

🌸 SYNOPSIS

void dcn60_populate_clk_table (struct clk_mgr_internal *clk_mgr , struct
       clk_limit_table *clk_table , const DalInitTable_t *init_table );

notice the void?? it returns nothing, it just does the thing and dips. main character energy fr fr 👑

---

🫶 ARGUMENTS

• clk_mgr — the clock manager instance. your ✨clock manager girlie✨, right there, handed to you.
• clk_table — the output clock table you're gonna populate. yes, output — this is the one that gets filled in. 🍓
• init_table — the DAL init table, transferred over from PMFW. it arrives as a little gift from the firmware. 💌

---

💖 DESCRIPTION

so what does it actually do? it reads the DPM clock levels straight out of the PPClocks array inside the DalInitTable_t — the same one that PMFW populates via the TABLE_DAL_INIT transfer. no cap, that's the whole job. 🌈

ngl the flow is simple but iconic: firmware hands over DalInitTable_t through TABLE_DAL_INIT, and this function goes shopping in the PPClocks array for those DPM clock levels. 💀✨
