STRUCT RKISP1_EXT_PARAMS_HST_CONFIG(9)

📦 version 7.3.1, in nixpkgs unstable

💅 struct rkisp1_ext_params_hst_config(9) — Kernel API Manual, but make it make sense

okay so bestie, gather round 🫶 this is a page straight out of the Kernel API Manual, and it's about one very specific little struct. We're talking struct rkisp1_ext_params_hst_config — the RkISP1 extensible params Histogram config. That's the whole vibe. Lowkey iconic, highkey niche. Let's go ✨

🌸 NAME 🌸

struct rkisp1_ext_params_hst_config — the RkISP1 extensible params Histogram config. no cap, that's literally what it is 💖

🎀 SYNOPSIS 🎀

struct rkisp1_ext_params_hst_config {
    struct rkisp1_ext_params_block_header header;
    struct rkisp1_cif_isp_hst_config config;
 };

look at her. two members. clean. main character energy 👑

🦋 Members 🦋

  • header — the RkISP1 extensible parameters header, fr fr. go check rkisp1_ext_params_block_header for the deets 💅
  • config — the Histogram statistics configuration itself. see rkisp1_cif_isp_hst_config if you wanna know what's inside 🍓

✨ Description ✨

So what is this thing? It's the RkISP1 extensible parameters Histogram statistics configuration block. periodt. 💀

And how do you know you're looking at one? It's identified by RKISP1_EXT_PARAMS_BLOCK_TYPE_HST_MEAS — that's the little name tag it wears at the party 🎀 iykyk.

🧚 SEE ALSO 🧚

okay this list is long long, but we do not skip, we do not summarize, we list every single one because that's the assignment 😭💜 source: kernel file ./include/uapi/linux/rkisp1-config.h.

like I said. long long. but we ate and left no crumbs 🍓🔥

ngl if you got here looking for the histogram block, you found her. go read rkisp1_cif_isp_hst_config(9) next, bestie 💖

and that's the page!! 🌈 sign-off time: this one lives in ./include/uapi/linux, dated October 2026, and the header/footer both say struct rkis...s_hst_config(9) (the man page truncated it, not me 💀). slay, go configure some histograms, mwah 🫶👑✨
