STRUCT SPE_SHADOW(9)

✨ struct spe_shadow(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a struct page, it's short, it's sweet, and it's literally just a mirror. let's get into it 🫶

🌸 NAME 🌸

struct spe_shadow — the logical spe shadow register area. that's it, that's the whole vibe. it's the shadow. of the spe registers. logical ones. ✨

🦋 SYNOPSIS 🦋

struct spe_shadow {
    u8 padding_0140[0x0140];
    u64 int_status_class0_RW;
    u64 int_status_class1_RW;
    u64 int_status_class2_RW;
    u8 padding_0158[0x0610-0x0158];
    u64 mfc_dsisr_RW;
    u8 padding_0618[0x0620-0x0618];
    u64 mfc_dar_RW;
    u8 padding_0628[0x0800-0x0628];
    u64 mfc_dsipr_R;
    u8 padding_0808[0x0810-0x0808];
    u64 mfc_lscrr_R;
    u8 padding_0818[0x0c00-0x0818];
    u64 mfc_cer_R;
    u8 padding_0c08[0x0f00-0x0c08];
    u64 spe_execution_status;
    u8 padding_0f08[0x1000-0x0f08];
 };

no cap, look at all those padding_ fields — they're the layout girlies keeping everything at the exact right offset so the real registers line up. respect the padding, she's doing the work 💀

🎀 Members 🎀

👑 Description 👑

okay the actual tea: this struct is a Read-only shadow of spe registers. that's the whole description, bestie. read-only. shadow. spe registers. periodt. 🙈

so like, you don't write to this, you observe it — it's the reflection in the mirror, not the mirror itself, and it's giving supporting-character energy in the best way 🌈

⭐ heads up bestie: this page doesn't list any errors, exit statuses, or env vars, so there's nothing more to spill — what you see is what you get 💜

and that's the whole page 🎀 dropping the footer deets so you have them: this lives under ./arch/powerpc/platforms/ps3, dated October 2026, and it's struct spe_shadow(9) all the way down. slay, bye 💖🦋✨
