ENUM C3_ISP_PARAMS_BLOCK_TYPE(9)

💅 enum c3_isp_params_block_type(9) — the glow-up

okay so this is from the Kernel API Manual, and bestie it is literally the cheat sheet for telling the C3 ISP driver which parameter block is which. no cap, it's a whole enum and it ate. ✨

✨ NAME ✨

enum c3_isp_params_block_type — the enumeration of C3 ISP parameter blocks 🎀

---

🦋 SYNOPSIS 🦋

enum c3_isp_params_block_type {
    C3_ISP_PARAMS_BLOCK_AWB_GAINS ,
    C3_ISP_PARAMS_BLOCK_AWB_CONFIG ,
    C3_ISP_PARAMS_BLOCK_AE_CONFIG ,
    C3_ISP_PARAMS_BLOCK_AF_CONFIG ,
    C3_ISP_PARAMS_BLOCK_PST_GAMMA ,
    C3_ISP_PARAMS_BLOCK_CCM ,
    C3_ISP_PARAMS_BLOCK_CSC ,
    C3_ISP_PARAMS_BLOCK_BLC ,
    C3_ISP_PARAMS_BLOCK_SENTINEL

};

like yes the blank line before the closing brace is supposed to be there, we don't question the kernel's aesthetic choices 💅

🌸 Constants 🌸

each of these is a little icon in the group chat, bestie — here's who's who:

• C3_ISP_PARAMS_BLOCK_AWB_GAINS — white balance gains 💖
• C3_ISP_PARAMS_BLOCK_AWB_CONFIG — the AWB statistic format configuration, and it covers all the blocks that control how stats are generated 🔥
• C3_ISP_PARAMS_BLOCK_AE_CONFIG — the AE statistic format configuration, again for all the blocks that control how stats are generated 🌈
• C3_ISP_PARAMS_BLOCK_AF_CONFIG — the AF statistic format configuration, same deal, all the blocks that control how stats are generated ⭐
• C3_ISP_PARAMS_BLOCK_PST_GAMMA — post gamma parameters 🎀
• C3_ISP_PARAMS_BLOCK_CCM — color correction matrix parameters 👑
• C3_ISP_PARAMS_BLOCK_CSC — color space conversion parameters 🦋
• C3_ISP_PARAMS_BLOCK_BLC — black level correction parameters 💜
• C3_ISP_PARAMS_BLOCK_SENTINEL — the first non-valid block index 🙈 (she's the boundary, the end of the line, the "you shall not pass")

---

💀 Description 💀

so the vibe here is: every single block configures one specific processing block of the C3 ISP. that's it, that's the tweet. and the block type is what lets the driver correctly interpret the parameters block data — without it the driver would be out here guessing and we simply do not do guessing in this house 😭
