qman_alloc_cgrid_range(9)

💖 NAME 💖

okay bestie, welcome to the Kernel API Manual ✨ this page is all about qman_alloc_cgrid_range(9) — literally allocating a contiguous range of CGR IDs. no cap, that's the vibe. 💅

🌸 SYNOPSIS 🌸

okay so the function's whole energy is this one line, and you gotta keep it exact:

int qman_alloc_cgrid_range (u32 *result , u32 count );

periodt. don't go "fixing" the spacing, bestie — it's giving original. 🫶

🎀 ARGUMENTS 🎀

• result — the API sets this to the base CGR ID of the allocated range 💖 so yeah, this is where the answer lands.
• count — the number of CGR IDs required. literally how many you're asking for, bestie.

🦋 DESCRIPTION 🦋

here's the whole plot, no extra lore: it returns 0 on success, or a negative error code. 😭 that's it. that's the tea. ngl, kind of iconic in its simplicity.
