fman_muram_init(9)

🌸 fman_muram_init 💅

okay so bestie, we're diving into the Kernel API Manual for fman_muram_init(9) — yes, a section-9 function, she's that girl. Let's get into it ✨

---

🎀 NAME 🎀

fman_muram_init — and honestly? The original page just... leaves the description blank. Nothing. Nada. A whole NAME section with no name-explanation. Iconic of her, lowkey. So no cap, there's no one-liner here — the function name is literally all you get, and the rest of the page does the talking. 🫶

---

⭐ SYNOPSIS ⭐

struct muram_info * fman_muram_init (phys_addr_t base , size_t size );

that's the whole vibe check, bestie — she returns a struct muram_info * and takes a phys_addr_t base plus a size_t size. Copy it exactly, no improvising 🔥

---

💖 ARGUMENTS 💖

• base — Pointer to base of memory mapped FM-MURAM. Like, the starting address of the FM-MURAM you've got mapped in. Your launchpad 🚀
• size — Size of the FM-MURAM partition. How much MURAM we're carving out, fr fr.

---

🦋 DESCRIPTION 🦋

So what she actually does: creates a partition in the MURAM. That's the whole job, and she does it slayfully 💅

The routine returns a pointer to the MURAM partition, and here's the part you cannot skip — this pointer must be passed as to all other FM-MURAM function calls. Every single one. She's the main character and everybody else needs her pointer to even function. Periodt. 👑

And a super important heads-up, ngl: no actual initialization or configuration of FM_MURAM hardware is done by this routine. Like, she sets up the partition bookkeeping and nothing else — the hardware itself? Not touched. Don't be out here expecting her to configure things, she's not that kind of function 🙈

---

✨ RETURN ✨

• Pointer to the FM-MURAM object 🎀 — the good ending
• or NULL for Failure 💀 — the bad ending, check your return value bestie

🌈 SEE ALSO 🌈

• Kernel file ./drivers/net/ethernet/freescale/fman/fman_muram.c — go read the source, iykyk 📖
• fman_muram_offset_to_vbase(9) — the offset-to-vbase bestie 🧚
• fman_muram_alloc(9) — the allocator, you'll be needing her 💜
• fman_muram_free_mem(9) — the one who cleans up after you (free your memory, queen) 🍓

---

lowkey reminder bestie: she makes the partition, she hands you the pointer, you pass that pointer everywhere, and the hardware configuration is not her problem 🔥

and that's the page, bestie! 🌸 mwah 💋
