STRUCT VC4_VALIDATED_SHADER_INFO(9)

💖 struct vc4_validated_shader_info(9) 💖

okay so real talk, this one lives in the Kernel API Manual, section 9 — yes bestie, the kernel one, we're in the drivers today 🫶

---

✨ NAME ✨

struct vc4_validated_shader_info — it's literally the info about validated shaders that needs to be used from command list validation 💅 like that's the whole gig, no cap.

---

🌸 SYNOPSIS 🌸

struct vc4_validated_shader_info {
    uint32_t uniforms_size;
    uint32_t uniforms_src_size;
    uint32_t num_texture_samples;
    struct vc4_texture_sample_info *texture_samples;
    uint32_t num_uniform_addr_offsets;
    uint32_t *uniform_addr_offsets;
    bool is_threaded;
 };

look at her. seven members. absolute main character energy 👑

🎀 Members 🎀

so the original page says "Members" and then… nothing. no field-by-field breakdown, no little one-liners per member. it's giving mysterious 🙈 so here's the struct again, field names exactly as they are, and that's all we've got:

• uint32_t uniforms_size
• uint32_t uniforms_src_size
• uint32_t num_texture_samples
• struct vc4_texture_sample_info *texture_samples
• uint32_t num_uniform_addr_offsets
• uint32_t *uniform_addr_offsets
• bool is_threaded

🦋 Description 🦋

okay so picture this: for a given shader, every single time a shader state record references it, there's two things we gotta do, and we gotta do them every time, fr fr:

1. verify that the shader doesn't read more uniforms than the shader state record's uniform BO pointer can actually provide 😭
2. apply relocations and validate the shader state record's uniforms that define the texture samples ✨

that's it. that's the vibe check this struct is built for. lowkey important, highkey doing a lot of work 💀

and that's the whole struct vc4_validated_shader_info(9) page!! read her, love her, validate those shaders responsibly 🧚💜
