dwc2_core_init(9)
π dwc2_core_init(9) β the kernel API manual, bestie edition π
okay so picture this: you're deep in the kernel, in the Kernel API Manual, and you've got this one function that's basically the main character of the DWC_otg controller setup arc. yeah. that one. let's get into it π«Ά
β¨ NAME β¨
dwc2_core_init β literally initializes the DWC_otg controller registers and gets the core all dolled up and ready for device mode or host mode operation π
like it's not just "poke a register," it's the whole glow-up. the core wakes up, the registers get set, and it's ready to serve either role. versatile icon behavior only π
π SYNOPSIS π
int dwc2_core_init (struct dwc2_hsotg *hsotg , bool initial_setup );
it returns an int, bestie. write that down. π
π¦ ARGUMENTS π¦
hsotgβ the programming view of the DWC_otg controller. this is your whole controller, the vibe, the entire situation. you hand it over and the function does its thing with it πΈinitial_setupβ abool, and the tea is simple: if it'strue, then this is the first init for this instance. first time's the charm, no cap. if it's not true, then it's not the first init, and that's also valid π
π₯ SEE ALSO π₯
okay so this function does not roll alone β it's giving ensemble cast energy, and the whole squad lives in the kernel file ./drivers/usb/dwc2/hcd.c. here's everybody, and yes, i listed all of them, because we don't do "etc." in this house π€

bestie reminder: the whole gang above is listed under that kernel file ./drivers/usb/dwc2/hcd.c, so if you're out here looking them up, that's where the party's at π§
and that's the page!! no notes, it ate, periodt π
this has been brought to you by ./drivers/usb/dwc2, dated October 2026 β mwah, go init something iconic π
