STRUCT TTM_POOL_ALLOC_STATE(9)

🌸 NAME 🌸

okay so bestie, welcome to the manual page for struct ttm_pool_alloc_state (that's section 9 of the Kernel API Manual, iykyk) — it's literally the current state of the tt page allocation process 💅

✨ SYNOPSIS ✨

struct ttm_pool_alloc_state {
    struct page **pages;
    struct page **caching_divide;
    dma_addr_t *dma_addr;
    pgoff_t remaining_pages;
    enum ttm_caching tt_caching;
 };

🎀 Members 🎀

• pages — pointer to the next tt page pointer you're gonna populate 👉 she's your write cursor, basically
• caching_divide — pointer to the first page pointer whose page has a staged-but-not-committed caching transition going from write-back to tt_caching 🦋 (yes, "staged but not committed" — she's in her situationship era, not official yet)
• dma_addr — pointer to the next tt dma_address entry to populate, if there is one ✨
• remaining_pages — how many pages are still left to populate 🔥
• tt_caching — the requested cpu-caching for the pages being allocated 👑
