okay so real talk, this is a page from the Kernel API Manual, and the star of the show is amdgpu_fence_driver_sw_init(9) β say that five times fast, i literally dare you π
β¨ NAME β¨
amdgpu_fence_driver_sw_init β bestie, this is the one that inits the fence driver for all possible rings. every single one. all of them. no cap π
π¦ SYNOPSIS π¦
int amdgpu_fence_driver_sw_init (struct amdgpu_device *adev );
like, it hands you back an int, and it wants exactly one thing. lowkey simple, highkey important π
β ARGUMENTS β
adevβ the amdgpu device pointer. that's it. that's the whole vibe check. your device, your pointer, your girl π«Ά
π₯ DESCRIPTION π₯
so what it does is init the fence driver for all possible rings β and yes, that means all asics. every single one of them, no exceptions, we're not playing favorites here π
but here's the tea: not all asics have all rings. some of these chips are out here living their best minimalist life with fewer rings than the others, and that's totally fine, we don't judge. so each asic will only start the fence driver on the rings it actually has, using amdgpu_fence_driver_start_ring π§
and then β the moment we've all been waiting for β it returns 0 for success. zero. the good zero. the iconic zero. when you see that 0 you know she ate π
ngl, don't sleep on that 0 β in kernel land, zero is the happy ending πβ¨
