t4_memory_rw_init(9)

💅 t4_memory_rw_init(9) ✨

okay so first things first: this is a page from the Kernel API Manual, section 9, and the star of the show is t4_memory_rw_init. she's a little function with a big job and honestly? she ate. 🫶

---

🌸 NAME 🌸

t4_memory_rw_init — grab the memory window's relative offset, base, and size. that's it, that's the whole vibe check. 💖

---

🎀 SYNOPSIS 🎀

int t4_memory_rw_init (struct adapter *adap , int win , int mtype , u32
*mem_off , u32 *mem_base , u32 *mem_aperture );

---

✨ ARGUMENTS ✨

bestie, here's the lineup — six of them, no cap:

• adap — the adapter. yes, the adapter. main character energy. 👑
• win — which PCI-E Memory Window we're using. pick one, babe. 🪟
• mtype — the memory type, and your options are: MEM_EDC0, MEM_EDC1, MEM_HMA, or MEM_MC. literally four whole choices. slay. 💅
• mem_off — the memory relative offset with respect to mtype. 🧭
• mem_base — the configured memory base address. 🏠
• mem_aperture — the configured memory window aperture. 🦋

---

💜 DESCRIPTION 💜

so what does she actually do? she gets the configured memory window's relative offset, base, and size. that's the whole thing. short, sweet, iconic. periodt. 🔥

ngl this one's a getter, not a doer — no wild side effects to warn you about here, the description really is just that one line. 💀

and that's the whole page, bestie 🎀 mwah 💋

tiny sign-off moment: this cutie came from ./drivers/net/ethernet/chelsio... (that's the source/version situation, she's shy and truncated) and the date on her birth certificate says October 2026. iconic. 🌸🦋⭐
