cik_fini(9)
π cik_fini(9) β the Kernel API Manual glow-up
okay so bestie, we're in the Kernel API Manual today and the main character is cik_fini. it's a kernel function, it's got one (1) job, and honestly? it does it. let's get into it β¨
β¨ NAME β¨
cik_fini β the asic specific driver and hw fini, aka the little goodbye ritual π
π¦ SYNOPSIS π¦
void cik_fini (struct radeon_device *rdev );
that's it. that's the whole signature. no sneaky extra params, no return value, she just goes π
πΈ ARGUMENTS πΈ
rdevβ aradeon_devicepointer, i.e. your whole entire GPU device struct. hand it over and let her do her thing π«Ά
π DESCRIPTION π
so here's the vibe: cik_fini tears down the asic specific driver variables and then programs the hw to an idle state (CIK). that's the whole arc β variables: packed up, hardware: chill mode, no notes π₯
and when does she get called? at driver unload. which is literally the last thing that happens, so this is her closing-number energy π
ngl this one's short but it's load-bearing β it's the teardown counterpart to cik_init, and yes, both of them are down there in SEE ALSO, iykyk π
π§ SEE ALSO π§
the whole friend group, fr fr β everyone who shares the ./drivers/gpu/drm/radeon group chat π
the file itself lives in:
Kernel file ./drivers/gpu/drm/radeon/cik.c

and that's the page, bestie π one tiny teardown function, one huge friend group. she ate and left no crumbs π
π real ones know this shipped out of./drivers/gpu/drm/radeon, dated October 2026, and it's filed undercik_fini(9)β go drink some water, mwah π«Άπ
