dpaa2_io_service_deregister(9)
π dpaa2_io_service_deregister β kernel API manual, but make it make sense
okay so bestie, welcome to the dpaa2_io_service_deregister(9) page π this one lives in the Kernel API Manual, and honestly? the name is a whole spoiler. it's the un-register. the breakup era. the "we're so done" of dpaa2_io_service_register. periodt.
β¨ NAME β¨
dpaa2_io_service_deregister β literally the opposite of 'register'. that's it, that's the whole vibe π«Ά
πΈ SYNOPSIS πΈ
void dpaa2_io_service_deregister (struct dpaa2_io *service ,
struct dpaa2_io_notification_ctx *ctx ,
struct device *dev );
π ARGUMENTS π
serviceβ the given DPIO service. yes girl, that one πctxβ the notification context. the lil' bookkeeping bestie.devβ the device that requests to be deregistered. it's giving "I would like to leave the group chat" energy π
π¦ DESCRIPTION π¦
okay so here's the tea, and it's important tea π₯ β this function should only be called after you've sent the MC command to detach the notification-producing device from the DPIO. like, order of operations is the whole moment here. don't call this first and then go detach, that's not the vibe. MC command first, then dpaa2_io_service_deregister. iykyk π
fr fr though, that "only after" is a real caveat, not a suggestion. respect the sequence β¨
