STRUCT RKISP1_CIF_ISP_GOC_CONFIG(9)

💖 struct rkisp1_cif_isp_goc_config — from the Kernel API Manual, section 9 🎀

okay so bestie, you opened the page for struct rkisp1_cif_isp_goc_config, and the manual it lives in is the Kernel API Manual (section 9, the kernel-struct girlies section). we're talking about Gamma Out correction config rn, it's giving "tiny struct, big responsibilities" energy, and honestly? iconic.

---

✨ NAME ✨

struct rkisp1_cif_isp_goc_config — the Configuration used by Gamma Out correction. that's literally what it is, no notes 💅

---

🌸 SYNOPSIS 🌸

like, here's the whole struct, verbatim, don't touch the formatting bestie:

struct rkisp1_cif_isp_goc_config {
    __u32 mode;
    __u16 gamma_y[RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES];
 };

---

🦋 Members 🦋

• mode — the goc mode 🎀 and it comes from enum rkisp1_cif_isp_goc_mode, so go check that one out.
• gamma_y — the gamma out curve y-axis for all color components. every single one. all of them. she's thorough 💜

---

⭐ Description ⭐

okay so here's the nuance, and it's actually lowkey important 👀 the number of entries in gamma_y isn't a fixed number-fixed number — it depends on the hardware revision, as is reported by the hw_revision field of the struct media_device_info that is returned by ioctl MEDIA_IOC_DEVICE_INFO. so like, check your hw rev before you assume anything, fr fr.

• V10 has RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES_V10 entries 🩵
• V12 has RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES_V12 entries 💖
• and RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES is equal to the maximum of the two 👑 (she's the ceiling, she's the bigger sister, she ate)

🫶 reminder bestie: don't hardcode the array count off the wrong revision, that's a vibe check you will fail 😭
