cdns3_gadget_ep0_enable(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… cdns3_gadget_ep0_enable πŸ’…

okay so this is a page straight out of the Kernel API Manual β€” yes bestie, the kernel has its own manual and it's giving official documentation energy ✨


🌸 NAME 🌸

cdns3_gadget_ep0_enable β€” and honestly? the original page left the description totally blank here 😭 so like, the name is the whole personality. it's the enable-ery for endpoint zero, and the details are right below, keep scrolling 🫢


πŸ¦‹ SYNOPSIS πŸ¦‹

int cdns3_gadget_ep0_enable (struct usb_ep *ep , const struct
       usb_endpoint_descriptor *desc );

so it takes two things and hands you back an int, periodt πŸ’…


πŸŽ€ ARGUMENTS πŸŽ€

  • ep β€” pointer to the endpoint zero object πŸ‘‘ this is the main character, the ep0 itself
  • desc β€” pointer to the usb_endpoint_descriptor πŸ“ the descriptor that describes the endpoint

⭐ DESCRIPTION ⭐

okay so here's the tea, and it's important: this function shouldn't be called by a gadget driver. like, at all. not even a little. 🚫

the reason? endpoint 0 is always active. it's already on. it never needed your help. it's that friend who's been ready to go for twenty minutes while you're still looking for your shoes πŸ™ˆ

so yeah β€” no cap, there is genuinely nothing for you to enable here, which is why the gadgets drivers out there should just leave it alone and let ep0 do its thing πŸ’–

the kernel file lives at ./drivers/usb/cdns3/cdns3-ep0.c and here's the whole squad:

eighteen functions, zero skips, we read the whole list 🫑


⚠️ tiny vibe check reminder: don't call this from a gadget driver. ep0 is already up and running, bestie. it's fine. it's thriving. πŸ’€
