πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– amdgpu_device_pm_notifier β€” the Kernel API Manual page, bestie edition πŸ’–

okay so this is straight out of the Kernel API Manual, and the star of the show is amdgpu_device_pm_notifier(9). it's giving "tiny function, big job" energy and i'm obsessed. let's get into it 🫢


✨ NAME ✨

amdgpu_device_pm_notifier β€” the notification block for Suspend/Hibernate events. literally its whole personality is "hey, the system's about to nap, lemme handle that" 😴


🌸 SYNOPSIS 🌸

int amdgpu_device_pm_notifier (struct notifier_block *nb , unsigned long mode , void *data );

that's the whole signature, no cap. screenshot it πŸ“Έ


πŸŽ€ ARGUMENTS πŸŽ€

  • nb β€” notifier block. yeah. the block. the notifier one. that's the description, bestie, i'm not gonna invent lore πŸ’…
  • mode β€” suspend mode. this is the one that tells you what kind of sleepy time we're talking about.
  • data β€” data. iconic, unbothered, says nothing. we love a mysterious king πŸ”₯

πŸ¦‹ DESCRIPTION πŸ¦‹

okay so real talk: this function gets called when the system is about to suspend or hibernate. like, the kernel hits it up right before the nap begins ✨

and what's it doing with that precious pre-nap moment? it's setting the appropriate flags so that eviction can be optimized in the pm prepare callback. that's it. that's the job. lowkey a king for it πŸ‘‘

no extra behaviour, no secret agenda β€” that's the entire documented scope. don't go making things up about it, that's not the vibe πŸ™ˆ

🌈 SEE ALSO 🌈

the kernel file lives here: ./drivers/gpu/drm/amd/amdgpu/amdgpu_device.c β€” go bother it directly if you want the source tea β˜•

and now the cast of everyone else in the amdgpu cinematic universe, in the exact order the manual gives them (yes, all of them, i would never do you dirty like that):


and that's the page!! no options section, no exit statuses, no env vars β€” just a little notifier doing its one job, and honestly? respect. πŸ’œ
