ENUM ATH5K_DMASIZE(9)

💅 enum ath5k_dmasize(9) — the Kernel API Manual moment

okay so bestie, we're looking at enum ath5k_dmasize today — it's the DMA size definitions one, and the whole vibe is 2^(n+2) ✨ lowkey iconic math.

---

🌸 NAME 🌸

enum ath5k_dmasize — DMA size definitions (2^(n+2)) 🎀

---

✨ SYNOPSIS ✨

enum ath5k_dmasize {
    AR5K_DMASIZE_4B ,
    AR5K_DMASIZE_8B ,
    AR5K_DMASIZE_16B ,
    AR5K_DMASIZE_32B ,
    AR5K_DMASIZE_64B ,
    AR5K_DMASIZE_128B ,
    AR5K_DMASIZE_256B ,
    AR5K_DMASIZE_512B

};

🦋 Constants 🦋

like, the whole squad, one by one:

• AR5K_DMASIZE_4B — 4Bytes 🍓
• AR5K_DMASIZE_8B — 8Bytes 🍓
• AR5K_DMASIZE_16B — 16Bytes 🌸
• AR5K_DMASIZE_32B — 32Bytes 🌸
• AR5K_DMASIZE_64B — 64Bytes (Default) 👑 this one's the main character, no cap
• AR5K_DMASIZE_128B — 128Bytes 💜
• AR5K_DMASIZE_256B — 256Bytes 💜
• AR5K_DMASIZE_512B — 512Bytes 🔥

---

💖 Description 💖

so these are literally used to set the DMA burst size on hw. that's the whole job. she's employed 💅

---

💀 Note 💀

⚠️ some platforms can't handle more than 4Bytes — be careful on embedded boards, fr fr. like do not just send it on an embedded board, that's giving chaos 😭
