π« sdma_v7_1_ring_get_wptr(9) π«
okay so bestie, welcome to the Kernel API Manual page for sdma_v7_1_ring_get_wptr β yes that's a whole mouthful, no I will not be shortening it, it's iconic and we respect it π
β¨ NAME β¨
sdma_v7_1_ring_get_wptr β literally just get the current write pointer π«Ά
π¦ SYNOPSIS π¦
uint64_t sdma_v7_1_ring_get_wptr (struct amdgpu_ring *ring );
that's it. that's the whole vibe check. she takes one thing and gives you back a uint64_t β¨
π ARGUMENTS π
ringβ amdgpu ring pointer π this is your ring, your main character, the whole reason we're here
πΈ DESCRIPTION πΈ
so what does she actually do? bestie, she gets the current wptr (that's the write pointer, iykyk) straight from the hardware. no cap, that's the entire job. pull the current wptr out of the hardware and hand it to you π₯
not me being obsessed with how simple this one is β some functions are whole sagas, and this one is just "go ask the hardware where the write pointer is at" and honestly? respect ππ

fr fr, go read them, they're all lowkey doing the most and you'll want the context π
okay that's the page!! mwah π this one came straight out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and it's filed under sdma_v7_1_ring_get_wptr(9) β go get that write pointer bestie, slay β¨ππ¦
