STRUCT PISP_BE_HOG_CONFIG(9)

💖 struct pisp_be_hog_config(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is the page for struct pisp_be_hog_config, aka the PiSP Back End HOG config. yes, HOG. no, not the animal. we'll get there. 🐷✨

---

🌸 NAME 🌸

struct pisp_be_hog_config — PiSP Back End HOG config, and she is exactly what she says on the tin 🫶

---

✨ SYNOPSIS ✨

struct pisp_be_hog_config {
    __u8 compute_signed;
    __u8 channel_mix[3];
    __u32 stride;
 };

ngl bestie, that's the whole struct. three fields. short, sweet, iconic. 💅

---

🎀 Members 🎀

• compute_signed — set it to 0 for unsigned gradients, or 1 for signed. that's it, that's the vibe check. ⭐
• channel_mix — the channels' proportions to use. it's a [3] array, so there are three of them, and they're doing proportions. main character energy honestly. 🌈
• stride — stride in bytes between blocks directly below. literally just walk down a block and count the bytes. slay. 🦋

🧚 Description 🧚

Histogram of Oriented Gradients configuration. yes THAT HOG — oriented gradients, being histogrammed, in your PiSP Back End. she's a config struct, she's doing her job, and she's doing it well. 💜

no cap: this is a config struct in the uapi headers, so it's the ABI face of the thing — treat the layout with respect. 👑
