cik_init(9)
π cik_init(9) β like, the whole Kernel API Manual moment β¨
okay so bestie, buckle in, because we're talking about cik_init, and she is literally the main character of driver startup π
πΈ NAME πΈ
cik_init β asic specific driver and hw init. yes that's it. that's the whole vibe. asic-specific driver stuff plus hardware init, and honestly? she ate π
β¨ SYNOPSIS β¨
int cik_init (struct radeon_device *rdev );
that's the whole signature, icon, no cap π«Ά
π¦ ARGUMENTS π¦
rdevβ aradeon_devicepointer. that's it. that's the whole argument. she takes one (1) pointer and she's off π
π DESCRIPTION π
okay so here's what's actually going down: cik_init sets up the asic specific driver variables and programs the hw to a functional state β and that's for CIK, just so we're clear π§
she gets called at driver startup, like the first day of school but for your GPU π
Returns 0 for success, and errors for failure. so like, 0 = slay, anything else = not slay π
π₯ SEE ALSO π₯
the kernel file is literally right here, go look at it:
./drivers/gpu/drm/radeon/cik.c
and now, the friend group β every single one of them, no skipping, we don't do that here π

like, that's the whole guest list, and yes I invited everyone π iykyk
π and that's the page!! brought to you straight out of./drivers/gpu/drm/radeon, dated October 2026, and styled ascik_init(9)β she's iconic, she's booked, she's periodt πβ¨
