dwc2_hsotg_ep0_mps(9)

✨ NAME ✨

okay so bestie, welcome to dwc2_hsotg_ep0_mps(9) — this is a page straight out of the Kernel API Manual, and it's basically a tiny little translator: it takes a max packet size and turns it into a register setting. that's the whole vibe. 💅

✨ SYNOPSIS ✨

like, here's the signature, no cap, copy it exactly:

u32 dwc2_hsotg_ep0_mps (unsigned int mps );

it hands you back a u32 (the register setting, obvs) and it takes exactly one lil argument. that's it. that's the function. 🎀

✨ ARGUMENTS ✨

• mps — the maximum packet size, measured in bytes. that's the number you're feeding in so it can get translated into the register setting. 🦋

✨ SEE ALSO ✨

okay so this is the part where the page name-drops literally everyone in the friend group. the kernel file doing the work here is ./drivers/usb/dwc2/gadget.c, and honestly the whole squad shows up — iykyk:
