πŸ’– dwc2_hcd_connect β€” the connect handler (yes bestie, that one) πŸ’–

okay so real talk, this is dwc2_hcd_connect(9), straight out of the Kernel API Manual ✨ β€” it's the lil function that handles connect of the HCD, and honestly? iconic. main character energy fr fr πŸŽ€


✨ SYNOPSIS ✨

void dwc2_hcd_connect (struct dwc2_hsotg *hsotg );

like. it returns nothing (void), it takes one pointer, and it does its little job. no cap. πŸ¦‹


🌸 ARGUMENTS 🌸

  • hsotg β€” Pointer to struct dwc2_hsotg πŸ’… that's it, that's the whole argument, she's simple, she's elegant, she's a pointer to the struct.

πŸ”₯ DESCRIPTION πŸ”₯

okay so this is the important bit and I need you to listen bestie, because this is not a drill 🚨:

Must be called with interrupt disabled and spinlock held 😭

that's it, that's the whole description, but it is load-bearing, like, do NOT come in here with your interrupts enabled and your spinlock just vibing unlocked. that's not the vibe. that's undefined-adjacent chaos energy and we don't do that 🫢


πŸ‘‘ SEE ALSO πŸ‘‘

like, 35 functions. thirty-five. she knows everyone at the party πŸŒˆπŸ’€


and that's the page!! πŸ’–βœ¨πŸ¦‹

this lil slice of kernel lore lives in ./drivers/usb/dwc2, dated October 2026, page version 9 β€” go forth bestie, connect that HCD, but lock your spinlock first πŸŽ€πŸ‘‘πŸ«Ά
