✨ ttm_object_device_release(9) ✨

okay so bestie, welcome to the ttm_object_device_release page β€” major Kernel API Manual energy, and honestly? it's a tiny little function with one job and it does it iconically πŸ’…


🌸 NAME 🌸

ttm_object_device_release β€” the function that releases all the data held by a ttm_object_device. that's it. that's the whole vibe. clean, simple, ate πŸŽ€


πŸ¦‹ SYNOPSIS πŸ¦‹

void ttm_object_device_release (struct ttm_object_device **p_tdev );

like, look at her. void return, one pointer-to-a-pointer argument. no cap, she's lowkey elegant 🫢


πŸ’– ARGUMENTS πŸ’–

  • p_tdev β€” a pointer to a pointer to the ttm_object_device object you're releasing. and listen, this is the important part: *p_tdev is gonna get set to NULL by this function. so don't be out here using it after, okay? it's giving dangling pointer trap if you're not paying attention πŸ™ˆ

πŸ”₯ DESCRIPTION πŸ”₯

So what does it actually do? It releases all the data associated with a ttm_object_device. all of it. every last crumb. πŸ“

Typically you'd call this from driver::unload, right before the device private data structure gets destroyed β€” like, the cleanup crew showing up before the demolition crew, y'know? main character energy for the teardown phase πŸ‘‘

fr fr, remember: after this runs, *p_tdev is NULL. that's not a bug, that's the whole design. respect it πŸ’…
