pxa27x_change_configuration(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… pxa27x_change_configuration(9) β€” like, the kernel API manual page, bestie ✨

Okay so this is a page from the Kernel API Manual, and it's all about pxa27x_change_configuration β€” yes that's a mouthful, we love her anyway 🫢


🌸 NAME 🌸

pxa27x_change_configuration β€” the girl who handles the SET_CONF usb request notification πŸ’Œ


✨ SYNOPSIS ✨

void pxa27x_change_configuration (struct pxa_udc *udc , int config );

That's it, that's the whole signature. No cap. πŸ”₯


πŸŽ€ ARGUMENTS πŸŽ€

  • udc β€” the udc device itself, the main character πŸ‘‘
  • config β€” the usb configuration, iykyk πŸ’…

πŸ¦‹ DESCRIPTION πŸ¦‹

So basically? She posts the request to the upper level. That's the whole vibe. πŸ“¬

And listen β€” don't use any pxa specific hardware configuration capabilities here. Not any. Zero. None. She's not about that hardware life, she's just passing the message along, periodt 🚫✨
