STRUCT IPU3_UAPI_FLAGS(9)

💅 struct ipu3_uapi_flags(9) — aka the group-chat of "which pipeline needs update"

okay so bestie, welcome to the Kernel API Manual ✨ this one's about struct ipu3_uapi_flags, and honestly? It's giving "one big bitfield of vibes". Every field is literally one bit, and its whole personality is answering the question: does this pipeline need an update or not? No cap.

so every single one of these is a lil one-bit switch. The rule is lowkey the same everywhere: 0 = no update, 1 = update. Periodt. The reserved ones are just sitting there being Not used 💀

• gdc — 0 = no update, 1 = update.
• obgrid — 0 = no update, 1 = update.
• reserved1 — Not used.
• acc_bnr — 0 = no update, 1 = update.
• acc_green_disparity — 0 = no update, 1 = update.
• acc_dm — 0 = no update, 1 = update.
• acc_ccm — 0 = no update, 1 = update.
• acc_gamma — 0 = no update, 1 = update.
• acc_csc — 0 = no update, 1 = update.
• acc_cds — 0 = no update, 1 = update.
• acc_shd — 0 = no update, 1 = update.
• reserved2 — Not used.

• acc_dpc — 0 = no update, 1 = update.
• acc_bds — 0 = no update, 1 = update.
• acc_anr — 0 = no update, 1 = update.
• acc_awb_fr — 0 = no update, 1 = update.
• acc_ae — 0 = no update, 1 = update.
• acc_af — 0 = no update, 1 = update.
• acc_awb — 0 = no update, 1 = update.
• reserved3 — Not used.
• lin_vmem_params — 0 = no update, 1 = update.
• tnr3_vmem_params — 0 = no update, 1 = update.
• xnr3_vmem_params — 0 = no update, 1 = update.
• tnr3_dmem_params — 0 = no update, 1 = update.
• xnr3_dmem_params — 0 = no update, 1 = update.
• reserved4 — Not used.
• obgrid_param — 0 = no update, 1 = update.
• reserved5 — Not used.

bestie note 🫶 the reserved fields are literally Not used — do not come for them, they're just padding holding space so the bit layout stays cute and aligned. Leave them alone, fr fr.
