✨ NAME ✨

ionic_get_cmb — Reserve cmb pages

like, it goes and grabs you some cmb pages. that's the job. no cap. 💅

---

🌸 SYNOPSIS 🌸

int ionic_get_cmb (struct ionic_lif *lif , u32 *pgid , phys_addr_t
*pgaddr , int order , u8 stride_log2 , bool *expdb );

here's the whole squad of parameters, look at them, they're all getting along 🫶

---

🦋 ARGUMENTS 🦋

• lif — Logical interface. the main character of this whole function, honestly.
• pgid — First page index. emphasis on first, she's the leader of the pack.
• pgaddr — First page bus addr (contiguous). yeah bestie, contiguous, they're all squished together 💜
• order — Log base two number of pages (PAGE_SIZE). it's giving exponent energy.
• stride_log2 — Size of stride to determine CMB pool. this one decides which pool you're swimming in 🏊
• expdb — Will be set to true if this CMB region has expdb enabled. her lil boolean moment ✨

🔥 RETURN 🔥

zero or negative error status

translation: 0 means slay, anything negative means it did not slay. check it always, i'm begging 😭
