parse_mtd_partitions(9)

💅 parse_mtd_partitions(9) — like, the Kernel API Manual, bestie 🎀

okay so this is a kernel API page (manual section 9, iykyk) and it's all about parse_mtd_partitions — the little function that goes "hmm, what partitions live on this MTD device?" and then actually registers them. no cap, it's giving matchmaker energy. 🌸

---

✨ NAME ✨

parse_mtd_partitions — parse and register MTD partitions 🦋

---

✨ SYNOPSIS ✨

int parse_mtd_partitions (struct mtd_info *master , const char *const
*types , struct mtd_part_parser_data *data );

literally copy that exactly, don't @ me 💅

---

✨ ARGUMENTS ✨

• master — the master partition (describes whole MTD device). it's the main character of the device, the whole thing, not a slice of it 👑
• types — names of partition parsers to try, or NULL if you're feeling spontaneous 🙈
• data — MTD partition parser-specific data. the extra lil' bag of stuff the parser might want 🎀

---

✨ DESCRIPTION ✨

so here's the vibe: this function tries to find & register partitions on the MTD device master. 🫶

it does that using the MTD partition parsers you listed in types. but — and this is the plot twist — if types is NULL, then the default list of parsers gets used instead. and what's in that default list? only the "cmdlinepart" and "ofpart" parsers ATM. that's it. that's the whole default squad. ⭐

---

✨ NOTE ✨

bestie, heads up 💀 — if there's more than one parser in types, the kernel only takes the partitions parsed out by the first parser. first one wins, everyone else is just standing there. periodt.

Also, this function may return:

• a negative error code in case of failure 😭
• the number of found partitions otherwise 🎉🔥

---

✨ SEE ALSO ✨

• Kernel file ./drivers/mtd/mtdpart.c
• __mtd_del_partition(9)
• mtd_part_get_compatible_parser(9)

okay that's the whole page, you ate that 💖 ngl this one was actually cute. stay hydrated, go parse some partitions, and remember: first parser takes all. 🌈
