✨ host1x_get_dma_mask 💅

okay so this is a page from the Kernel API Manual, and honestly? it's a short one, so we can absolutely get through it together bestie 🫶

🌸 NAME 🌸

host1x_get_dma_mask — literally just query the supported DMA mask for host1x, that's the whole vibe 🎀

---

⭐ SYNOPSIS ⭐

u64 host1x_get_dma_mask (struct host1x *host1x );

like yes, that's the entire signature, no cap 💖

---

🦋 ARGUMENTS 🦋

• host1x — the host1x instance you're asking about. that's it. that's the argument ✨

👑 DESCRIPTION 👑

okay so pay attention here bestie because this is the one (1) thing this page wants you to remember:

note that this returns the supported DMA mask for host1x, which can be different from the applicable DMA mask under certain circumstances 🔥

like, read that again. supported ≠ applicable. they can diverge and the circumstances are, and I quote, "certain" 🙈 so don't go assuming they're the same thing, fr fr 💀
