STRUCT PVR_FW_MIPS_DATA(9)

💖 struct pvr_fw_mips_data(9) 💖

okay so bestie, welcome to the Kernel API Manual — this one's a kernel struct page and it's literally the little info bundle that holds all the MIPS-specific data for the PowerVR firmware loader. it's giving "backstage pass to the MIPS boot process" energy, and honestly? iconic. 🧚✨

🌸 SYNOPSIS 🌸

struct pvr_fw_mips_data {
    struct page *pt_pages[PVR_MIPS_PT_PAGE_COUNT];
    u32 *pt;
    dma_addr_t pt_dma_addr[PVR_MIPS_PT_PAGE_COUNT];
    dma_addr_t boot_code_dma_addr;
    dma_addr_t boot_data_dma_addr;
    dma_addr_t exception_code_dma_addr;
    u32 cache_policy;
    u32 pfn_mask;
 };

like, that's the whole shape of it — copy it exactly bestie, no cap, not a single character changed. 💅

🎀 Members 🎀

• pt_pages — these are the pages holding the MIPS pagetable. the actual storage, the real estate, the moments. 🏠
• pt — a pointer to the CPU mapping of the MIPS pagetable, so the CPU can actually get in there and look around. 👀
• pt_dma_addr — the DMA mappings of the MIPS pagetable — same pagetable, DMA-flavoured address era. ✨
• boot_code_dma_addr — the DMA address of the MIPS boot code. the main-character entrance, basically. 👑
• boot_data_dma_addr — the DMA address of the MIPS boot data — everything the boot code needs to slay. 🍓
• exception_code_dma_addr — the DMA address of the MIPS exception code, aka the "when things go sideways" contingency. and they WILL go sideways, so this is highkey important. 💀
• cache_policy — the cache policy for this processor. the vibe check for caching, fr fr. 🌈
• pfn_mask — the PFN mask for MIPS pagetable — the masking moment, we love to see it. 🎀

🦋 SEE ALSO 🦋

• Kernel file ./drivers/gpu/drm/imagination/pvr_fw_mips.h — go read the header bestie, iykyk 🫶

💖 reminder: every field above is listed in the order the struct declares it, and the option-ish names are literal C members — don't go renaming them in your head, the compiler will not be forgiving and neither will i 😭

that's the whole page!! it lives under ./drivers/gpu/drm/imagination, dated October 2026 in the Kernel API Manual — mwah, go forth and boot some MIPS firmware, you've got this 💅✨🦋💖
