🌸 NAME 🌸

gfx_v7_0_ring_test_ring — basic gfx ring test, no cap 💅

🎀 SYNOPSIS 🎀

int gfx_v7_0_ring_test_ring (struct amdgpu_ring *ring );

🦋 ARGUMENTS 🦋

  • ring — the amdgpu_ring structure that's holding all the ring info 🫶 like it literally carries the whole ring's lore, and we're passing it in so the function knows which ring it's testing, periodt.

✨ DESCRIPTION ✨

okay so here's the whole situation 🌈 — you allocate a scratch register and then you write to it using the gfx ring (CIK). that's it, that's the move 💫

it's giving basic gfx ring test, and its whole job is to verify that the ring is actually working 😤 like, is the ring okay? is it alive? we're checking. very main character energy of it honestly.

it's used by gfx_v7_0_cp_gfx_resume — so yeah, whenever the driver is resuming the gfx command processor, this little icon comes out to make sure things are slaying correctly 👑

returns 0 on success 🟢, error on failure 🔴. that's the deal, fr fr.
