STRUCT VSP1_DU_WRITEBACK_CONFIG(9)

💖 NAME 💖

Hiii bestie, welcome to the Kernel API Manual page for struct vsp1_du_writeback_config(9)! 💅 This is literally struct vsp1_du_writeback_config — VSP writeback configuration parameters — and it’s giving “the little bag of params for writeback setup,” no cap. ✨

🌸 SYNOPSIS 🌸

Here’s the struct in all its glory — copy it exactly, don’t freestyle the types, bestie 🫶:

       struct vsp1_du_writeback_config {
           u32 pixelformat;
           unsigned int pitch;
           dma_addr_t mem[3];
        };

🎀 Members 🎀

Okay so there are exactly three members, and they’re lowkey iconic 💖:

• pixelformat — the plane pixel format (V4L2 4CC), periodt.
• pitch — line pitch in bytes for the first plane, slay.
• mem — DMA memory address for each plane of the frame buffer; it’s mem[3], so yes, three addresses, iykyk. 🦋

Go look at these too, bestie — they’re all linked in the lore 🌈:

okay that’s the whole page, mwah 💅 — source/version line was ./include/media, the date was October 2026, and the footer title was struct vsp1...eback_config(9); bye bestie, go be a main character in kernel land 🫶🎀✨
