β¨ NAME β¨
amdgpu_fence_need_ring_interrupt_restore β a lil helper function whose whole entire job is to check whether fence driver interrupts need to be restored. that's it. that's the gig π
πΈ SYNOPSIS πΈ
bool amdgpu_fence_need_ring_interrupt_restore (struct amdgpu_ring *ring
);
literally one function, one argument, returns a bool. she's lowkey minimal and I respect it π
π¦ ARGUMENTS π¦
ringβ the ring that to be checked, iykyk. that's the one you're handing over, bestie π
β DESCRIPTION β
so here's the tea β β interrupts for rings that belong to GFX IP don't need to be restored when the target power state is s0ix. not me learning power states at 2am π
and then the actual answer: return true if you need to restore interrupts, false otherwise. simple, clean, iconic π
