STRUCT PCH_GBE_TX_RING(9)

💅 struct pch_gbe_tx_ring(9) — like, the whole tx ring situation

okay bestie, so this is a page from the Kernel API Manual and it's all about struct pch_gbe_tx_ring, which is literally the tx ring info. that's the NAME section, we're done with it, slay. 🎀

---

✨ SYNOPSIS ✨

here's the whole vibe, character for character, no cap:

struct pch_gbe_tx_ring {
    struct pch_gbe_tx_desc *desc;
    dma_addr_t dma;
    unsigned int size;
    unsigned int count;
    unsigned int next_to_use;
    unsigned int next_to_clean;
    struct pch_gbe_buffer *buffer_info;
 };

🌸 MEMBERS 🌸

okay so every single field, and what it actually does — paying attention bestie, this is the whole point 👑

• desc — pointer to the descriptor ring memory. it's giving "here's where the actual ring lives" energy ✨
• dma — the physical address of the descriptor ring. yes, physical, not virtual, don't get it twisted 💅
• size — the length of the descriptor ring, and it's measured in bytes 🍓
• count — how many descriptors are chilling in the ring 🔥
• next_to_use — the next descriptor that's gonna get a buffer associated with it. like, the one that's up next 👑
• next_to_clean — the next descriptor to check for the DD status bit. yep, that's the whole description, that's the assignment 🫶
• buffer_info — an array of buffer information structs. plural, an array, many of them 🌈

fr fr read the rx one too, she's the sister struct and she ate 💀

and that's the page!! sign-off time: this lil gem comes from the ./drivers/net/ethernet/oki-sem... corner of the source, and it's dated October 2026 ⭐ genuinely iconic, go read the header file, ily, bye 💖🧚
