dcn60_build..._with_action(9)

💅 dcn60_build_bandwidth_clocks_block_sequence_with_action — from the Kernel API Manual, section 9, bestie 🎀

okay so like, this is a page straight out of the Kernel API Manual (that's the manual name, not me being dramatic — well, partly) and it's about a function with the LONGEST name ever 💀. Say it with me: dcn60_build_bandwidth_clocks_block_sequence_with_action. Iconic. No notes.

✨ NAME ✨

dcn60_build_bandwidth_clocks_block_sequence_with_action — build the SMU message sequence from the action struct, and like... without mutating clk_mgr state. She's read-only, she's respectful, she does NOT touch your clock manager. periodt 💅

---

🌸 SYNOPSIS 🌸

unsigned int dcn60_build_bandwidth_clocks_block_sequence_with_action
(struct dcn60_clk_mgr_block_sequence *block_sequence , struct
dcn60_bandwidth_clocks_update_action *action , struct clk_mgr
*clk_mgr_base , struct dc_clocks *new_clocks );

yes the whole thing. she's long. she's beautiful. she's giving main character energy 👑

🦋 ARGUMENTS 🦋

• block_sequence — the output array of block sequence steps 🫶 like this is where the steps go, bestie.
• action — the action struct, and ngl it's supposed to be populated by dcn60_make_bandwidth_clocks_update_action. Someone else did the prep work, we're just building here.
• clk_mgr_base — the current clock manager state. It's read-only, okay?? Used for the original values. We look, we don't touch 🙈✨
• new_clocks — the requested clock values, aka what goes into the message parameters. Slay.

---

⭐ RETURN ⭐

the number of steps written to block_sequence — that's it, that's the return value 💖

okay little reminder for the people in the back: clk_mgr_base is read-only in this function. Like, the whole point is not mutating clk_mgr state. do NOT come for her and try to write to it 💀
