v4l2_isp_buffer_size(9)

💖 NAME 💖

okay so this is v4l2_isp_buffer_size — the ✨ Kernel API Manual ✨ page for it, and the whole entire job of this macro is Calculate size of v4l2_isp_buffer. that's it, that's the vibe. it does the math so you don't have to 🧮💅

🎀 SYNOPSIS 🎀

v4l2_isp_buffer_size (max_size );

🌸 ARGUMENTS 🌸

• max_size — the total size of the ISP configuration or statistics blocks. like, both of them, that's the number she wants 🫶

🦋 DESCRIPTION 🦋

bestie, here's the situation: users of v4l2-isp are gonna roll up with differing sized data arrays for parameters and statistics, depending on their specific blocks. everybody's built different, no cap. so drivers need to be able to calculate the appropriate size of the buffer to accommodate all the ISP blocks supported by the platform — and that's the whole reason this macro exists. it's literally a convenient tool for the calculation. ✨

the intended users of this function are drivers initializing the size of their metadata (parameters and statistics) buffers. if that's you, hi, this page is for you, main character energy 🔥

👑 SEE ALSO 👑

go look at these, iykyk:

• kernel file ./include/media/v4l2-isp.h
• v4l2_isp_params_validate_buffer_size(9), struct v4l2_isp_params_block_type_info(9), v4l2_isp_params_validate_buffer(9), struct v4l2_isp_stats_block_type_info(9), v4l2_isp_stats_init_buffer(9), v4l2_isp_stats_init_block(9)

💀 that's the whole page fr fr. this one lives in ./include/media, it's from October 2026, and it's part of the Kernel API Manual — so like, <rainbow>slay, go size those buffers</rainbow> 🌈💜 🎀
