ENUM RPPX1_PARAMS_BLOCK_TYPE(9)

💅 enum rppx1_params_block_type(9) — from the Kernel API Manual, section 9, bestie ✨

okay so real talk, this page lives in the Kernel API Manual (section 9 ofc) and it's all about the RPP-X1 extensible params block types. it's giving "enum era" and honestly? iconic. let's get into it 🎀

✨ NAME ✨

enum rppx1_params_block_type — the RPP-X1 extensible params block types. that's it, that's the vibe 💖

};

look at that list. eighteen whole constants. she ate and left no crumbs 🔥

🌸 Constants 🌸

every single one of them, in order, no skipping, periodt:

• RPPX1_PARAMS_BLOCK_TYPE_WBMEAS_POST — AWB Measurement Configuration. the autowhite-balance measuring block, living its best POST life 💫
• RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE1 — PRE1 pipe White Balance Gains. gains go brrr in the first pipe 🫶
• RPPX1_PARAMS_BLOCK_TYPE_AWBG_PRE2 — PRE2 White Balance Gains. same energy, second pipe ✨
• RPPX1_PARAMS_BLOCK_TYPE_AWBG_POST — MAIN_POST White Balance Gains. main-character POST gains, obviously 👑
• RPPX1_PARAMS_BLOCK_TYPE_EXM_PRE1 — PRE1 pipe Exposure Measurement. exposure gets measured over here 📏
• RPPX1_PARAMS_BLOCK_TYPE_EXM_PRE2 — PRE2 pipe Exposure Measurement. and over here too 💜
• RPPX1_PARAMS_BLOCK_TYPE_HIST_PRE1 — PRE1 pipe Histogram Measurement. histogram moment, PRE1 edition 🍓
• RPPX1_PARAMS_BLOCK_TYPE_HIST_PRE2 — PRE2 pipe Histogram Measurement. histogram moment, PRE2 edition 🌈
• RPPX1_PARAMS_BLOCK_TYPE_HIST_POST — POST pipe Histogram Measurement. histogram moment but make it POST 💅
• RPPX1_PARAMS_BLOCK_TYPE_BLS_PRE1 — PRE1 pipe Black Level Subtraction. black levels? subtracted. no cap 🖤
• RPPX1_PARAMS_BLOCK_TYPE_BLS_PRE2 — PRE2 pipe Black Level Subtraction. subtracted again, PRE2 flavored ✨
• RPPX1_PARAMS_BLOCK_TYPE_CCOR_POST — POST pipe Color Correction. fixing up your colors, POST pipe style 🎨
• RPPX1_PARAMS_BLOCK_TYPE_LSC_PRE1 — PRE1 pipe Lens Shading Correction. shady lens? corrected 🔆
• RPPX1_PARAMS_BLOCK_TYPE_LSC_PRE2 — PRE2 pipe Lens Shading Correction. same but PRE2, iykyk 🌸
• RPPX1_PARAMS_BLOCK_TYPE_GA_HV — Human Vision Pipe Gamma Out Correction. for the human eyeballs 👀💖
• RPPX1_PARAMS_BLOCK_TYPE_GA_MV — Machine Vision Gamma Out Correction. for the robot eyeballs 🤖✨
• RPPX1_PARAMS_BLOCK_TYPE_LIN_PRE1 — PRE1 pipe Linearization (Sensor De-gamma). un-gamma-ing the sensor, PRE1 🧚
• RPPX1_PARAMS_BLOCK_TYPE_LIN_PRE2 — PRE2 pipe Linearization (Sensor De-gamma). un-gamma-ing the sensor, PRE2 💫

💀 NOTE 💀

Only append to the enumeration as the numbers are uAPI.

fr fr, this is the important one bestie — only append. the numbers are uAPI and they are NOT up for negotiation. do not reorder, do not insert in the middle, do not pass go. append at the end or catch these hands 😭💅
