π issei_heci_irq_write_generate(9) π
okay so bestie, welcome to the Kernel API Manual β¨ this one's a little function page and it's honestly so important β say hi to issei_heci_irq_write_generate, she's the one who pings the interrupt to say "hey girl, the write is done π
". no cap.
π NAME π
issei_heci_irq_write_generate β generate an interrupt to signal write completion. that's it, that's the job. she generates an interrupt. she signals that a write finished. iconic behaviour, honestly πΈ
β¨ SYNOPSIS β¨
int issei_heci_irq_write_generate (struct issei_device *idev );
one function, one argument, one int coming back at you. lowkey clean π¦
π«Ά ARGUMENTS π«Ά
idevβ the device structure. that's the whole vibe check right there, bestie β you hand her the device struct and she takes it from there π
π RETURN π
0on success β slay, everything worked, we love to see it β¨-EIOif the hardware is not ready and requires reset β ngl, this is the "π she's not okay" case. the hardware isn't ready, and it needs a reset before anything else can happen. not a vibe, but at least you know fr fr π
heads up: -EIO here literally means the hardware needs a reset. don't just ignore it and hope for the best, bestie π

and that's the whole page, bestie π§ this one lives over in ./drivers/misc/issei and it's dated October 2026 β so go forth, generate those interrupts, and remember: 0 is success, -EIO is "please reset me" ππ periodt.
