💖 enum v4l2_isp_version(9) — Kernel API Manual 💖

okay bestie, welcome to the Kernel API Manual page for enum v4l2_isp_version(9). It’s giving kernel-constant lore, but make it cute: this one is all about V4L2 ISP serialization format versioning. 🎀

💅 NAME

enum v4l2_isp_version — V4L2 ISP serialization format versioning. periodt.

🌸 SYNOPSIS

enum v4l2_isp_version {
    V4L2_ISP_VERSION_V0 ,
    V4L2_ISP_VERSION_V1

};

🎀 Constants

• V4L2_ISP_VERSION_V0 — First version of the V4L2 ISP serialization format (for compatibility). 🫶
• V4L2_ISP_VERSION_V1 — First version of the V4L2 ISP serialization format. ✨

🦋 Description

So V0 and V1 are identical, and that is literally on purpose — it’s to support drivers compatible with the V4L2 ISP format already upstreamed which use either 0 or 1 as their versioning identifier. Both V0 and V1 refers to the first version of the V4L2 ISP serialization format. no cap. 💅

Future revisions of the V4L2 ISP serialization format should start from the value of 2. 🔥
