wmi_buffer_block(9)

💅 wmi_buffer_block(9) — a Kernel API Manual moment 🎀

okay bestie, welcome to the Kernel API Manual entry for wmi_buffer_block, and ngl this one is lowkey iconic. it's giving "is this address even real" energy, and honestly? we're obsessed. ✨

---

🌸 NAME 🌸

wmi_buffer_block — check address validity for WMI buffer, and remap it if needed, periodt 💅

---

🦋 SYNOPSIS 🦋

void __iomem * wmi_buffer_block (struct wil6210_priv *wil , __le32 ptr_ , u32 size );

---

🎀 ARGUMENTS 🎀

• wil — driver data 🫶 like, the whole context of the driver, bestie
• ptr_ — the internal (linker) fw/ucode address. yes, fw/ucode, both, that's literally what it says ⭐
• size — if it's non zero, we validate that the block does not exceed the device memory (bar). zero? no block check, iykyk 🙈

---

💖 DESCRIPTION 💖

so, a valid buffer should be DWORD aligned. that's the vibe check. ✨

then it returns the address for accessing that buffer from the host. and if the buffer is not valid? it returns NULL. no cap, that's it, that's the whole function. 💀
