okay so bestie, we're in the Kernel API Manual today and the star of the show is sdma_v4_4_2_ring_get_rptr(9) β say that five times fast, i dare you π«Ά
β¨ NAME β¨
sdma_v4_4_2_ring_get_rptr β get the current read pointer π
like, literally just go grab the read pointer. that's the whole vibe.
πΈ SYNOPSIS πΈ
uint64_t sdma_v4_4_2_ring_get_rptr (struct amdgpu_ring *ring );
yup, that's it. one arg, returns a uint64_t, slays every time β¨
π¦ ARGUMENTS π¦
ringβ amdgpu ring pointer π« (the ring in question, the main character, the one we're reading from)
π DESCRIPTION π
Get the current rptr from the hardware. π―
that's it. that's the function. it goes and asks the hardware what the read pointer is at, and the hardware tells it, and everyone moves on with their day. no cap, this one is short and sweet and honestly? iconic. π
