amdgpu_ring_init(9)

🌸 NAME 🌸

amdgpu_ring_init(9) — okay bestie, this is from the Kernel API Manual, and the function is amdgpu_ring_init: init driver ring struct. ✨

✨ SYNOPSIS ✨

int amdgpu_ring_init (struct amdgpu_device *adev , struct amdgpu_ring
*ring , unsigned int max_dw , struct amdgpu_irq_src *irq_src , unsigned
int irq_type , unsigned int hw_prio , atomic_t *sched_score );

🫶 ARGUMENTS 🫶

• adev — the amdgpu_device pointer, aka the GPU situation you're working with 💖
• ring — the amdgpu_ring structure holding ring information 🎀
• max_dw — maximum number of dw for the ring alloc, so set that limit bestie ✨
• irq_src — interrupt source to use for this ring 🦋
• irq_type — interrupt type to use for this ring 🌸
• hw_prio — ring priority, and it's giving NORMAL/HIGH 💅
• sched_score — optional score atomic shared with other schedulers, no cap 👑

💅 DESCRIPTION 💅

So what this does is initialize the driver information for the selected ring, for all asics. That's the whole vibe. ✨

It returns 0 on success, and an error on failure. Periodt. 💖
