π pch_udc_read...e_interrupts(9) β¨
okay bestie, so this is a page straight out of the Kernel API Manual β yes, the big serious one β and it's about one lil function that just wants to tell you what the device is yelling about. no cap, it's shorter than my attention span, so let's go π«Ά
πΈ NAME πΈ
pch_udc_read_device_interrupts β literally just read the device interrupts. that's it. that's the whole vibe check π
π SYNOPSIS π
u32 pch_udc_read_device_interrupts (struct pch_udc_dev *dev );
so you hand it a dev, it hands you back a u32. slay. iconic signature behavior periodt.
π¦ ARGUMENTS π¦
devβ reference to structure of typepch_udc_regsβ okay so this is your pointer to the device thingy, and it's the only thing you gotta pass in. she's low maintenance π
and then there's the Retern β yes, spelled like that in the original, leaving it exactly as found, iykyk π β which gives you the device interrupts. that's your return value, bestie. the interrupts. in a u32. go read em π
β SEE ALSO β
okay this list is long, like, main-character-long, so buckle up. everything under the kernel file ./drivers/usb/gadget/udc/pch_udc.c plus a whole friend group of structs and functions:

like I said. a lot. but every single one of them is here, fr fr, nothing skipped π
ngl there's no OPTIONS section, no environment variables, no exit statuses, no examples, no bugs, no authors and no license line on this one β she's a tiny page and we love her for it π
and that's the whole page, bestie!! π§β¨ take care of her β she lives in ./drivers/usb/gadget/udc, dated October 2026, and she's filed under the Kernel API Manual. mwah ππΈπ
