💅 convert_hw_matrix(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for convert_hw_matrix, and honestly? it's giving "small function, big job" and I'm obsessed 🎀

🌸 NAME 🌸

convert_hw_matrix — converts HW values into a fixed31_32 matrix 💖

like, that's literally her whole personality. hardware numbers in, fancy fixed-point matrix out. slay.

---

✨ SYNOPSIS ✨

void convert_hw_matrix (struct fixed31_32 *matrix , uint16_t *reg , enum
cm_gamut_coef_format format , uint32_t buffer_size );

no cap, that's the whole signature 🫶

---

🦋 ARGUMENTS 🦋

• matrix — the fixed point 31.32 matrix 💅 this is where the glow-up lands
• reg — array of register values, aka the raw HW gossip 🌸
• format — -- undescribed -- 🙈 yeah bestie, the original docs literally did not describe this one. we're not gonna invent lore for it, that's not the vibe. it's of type enum cm_gamut_coef_format and that's all we're told 💀
• buffer_size — size of the array of register values, so she knows how much reg to read 👑

---

🌈 DESCRIPTION 🌈

Okay so picture this: the hardware has its own little register spec format called S2D13, right? and convert_hw_matrix takes that HW register spec defined format S2D13 and converts it into a fixed-point 31.32 matrix ✨ literally translating hardware-speak into fixed-point matrix-speak. main character energy fr fr 💜

💀 reminder bestie: format is genuinely marked -- undescribed -- in the original. do not come for me, come for the person who wrote the doc 🙈
