dce121_cloc...xgmi_ss_info(9)

💫 dce121_clock_patch_xgmi_ss_info — like, the whole scoop 💫

okay bestie, so we're in the Kernel API Manual (section 9, dce121_cloc...xgmi_ss_info(9), iykyk) and this is genuinely one of those little functions that just quietly does its job and slays 🎀

✨ NAME ✨

dce121_clock_patch_xgmi_ss_info — saves the XGMI spread spectrum info. that's it, that's the vibe 💅

---

🌸 SYNOPSIS 🌸

void dce121_clock_patch_xgmi_ss_info (struct clk_mgr_internal
*clk_mgr_dce );

no return value, no drama — it's a void function, she just does the thing and leaves 🦋

---

🧚 ARGUMENTS 🧚

• clk_mgr_dce — the clock manager internal structure. that's the one and only thing you hand her 🫶

---

🔥 DESCRIPTION 🔥

okay so picture this: the function reads the XGMI spread spectrum info from VBIOS and then saves it inside the dce clock manager. lowkey important stuff ✨

here's the twist though — this operation will overwrite the existing dprefclk SS values if the vBIOS query succeeds. if it doesn't succeed? she does nothing. not a single thing. respects the boundaries fr fr 🙈

oh and also, she sets the ->xgmi_enabled flag. main character energy, honestly 👑
