STRUCT TMC_PAGES(9)

✨ struct tmc_pages 💅 (section 9, Kernel API Manual, bestie)

okay so real talk — this is struct tmc_pages, from the Kernel API Manual, section 9, and it's literally just a little cutie container for a Collection of pages used for SG. that's it, that's the whole vibe 🎀

🌸 NAME 🌸

struct tmc_pages — a Collection of pages used for SG. no cap, that's the entire job description 🫶

---

🦋 SYNOPSIS 🦋

struct tmc_pages {
    int nr_pages;
    dma_addr_t *daddrs;
    struct page     **pages;
 };

like… look at her. three members. main character energy, minimal effort ✨ (yes the indentation on that closing brace is exactly like that, we don't fix what isn't broken 💅)

---

👑 Members 👑

• nr_pages — Number of pages in the list. the headcount. the attendance sheet. how many pages we're actually dealing with 📋
• daddrs — Array of DMA'able page address. (yes, "address" singular, that's what the page says, we are not editing the page, we respect the page 🙈) it's the array of DMA-able page addresses, plural energy, singular spelling 🔥
• pages — Array pages for the buffer. the actual struct page ** gang, all lined up for the buffer 🧚 (and yes, "Array pages" — again, not my words, I'm just the messenger 😭)

🌈 SEE ALSO 🌈

• Kernel file ./drivers/hwtracing/coresight/coresight-tmc.h ← go read it, iykyk 📂

like genuinely go click through those, they're the whole friend group 💜
