π dpm_resume_noirq(9) β from the Kernel API Manual, bestie π«Ά
okay so picture this: it's a kernel manual page, it's called dpm_resume_noirq, and it is literally the glow-up moment for your devices. welcome to the group chat, we're learning power management π
β¨ NAME β¨
dpm_resume_noirq β Execute "noirq resume" callbacks for all devices. no cap, that's the whole vibe πΈ
π¦ SYNOPSIS π¦
void dpm_resume_noirq (pm_message_t state );

π₯ DESCRIPTION π₯
bestie, here's the tea β β dpm_resume_noirq invokes the "noirq" resume callbacks for all the devices hanging out in dpm_noirq_list, and then it lets device drivers' interrupt handlers be called. yes, that's right, we're bringing the interrupts back online πβ¨ the devices are waking up and honestly? main character energy.

go read them all, i'll wait π§π
so yeah, that's the whole page β every flag-free, argument-having, callback-invoking detail, preserved exactly. iykyk π
okay and one last thing before you close the tab π this whole lil doc lives in ./drivers/base/power, it's stamped October 2026, and its name is dpm_resume_noirq(9) β slay, periodt, bye bestie πβ¨π¦
