okay bestie, welcome to the Kernel API Manual, section 9 β yes, the big-kid kernel section, we're literally in the driver guts rn and it's giving main character energy π₯
β¨ NAME β¨
jpeg_v1_0_decode_ring_get_rptr β get read pointer π
πΈ SYNOPSIS πΈ
uint64_t jpeg_v1_0_decode_ring_get_rptr (struct amdgpu_ring *ring );
no cap, that's the whole signature β she takes one arg and hands you back a uint64_t π«Ά
π¦ ARGUMENTS π¦
ringβ anamdgpu_ringpointer. yep, that's it, that's the entire vibe check π
β DESCRIPTION β
Returns the current hardware read pointer. that's the whole thing, bestie β she reads the rptr straight off the hardware and gives it to you. iconic, lowkey, no notes π
π SEE ALSO π
the kernel file itself lives at ./drivers/gpu/drm/amd/amdgpu/jpeg_v1_0.c β go say hi to her, she's the source of truth fr fr π
and here's the whole squad, all in the same (9) section because they're all family:

like, get rptr, get wptr, set wptr, insert start, insert end, emit a fence, emit an ib, early init, sw init, sw fini, start, parse cs β the full ring lifecycle ate and left zero crumbs π
ngl the page title up top is doing that truncatedjpeg_v1_0_de...ing_get_rptrthing (the terminal had to cut her off, so rude π) β the real full name isjpeg_v1_0_decode_ring_get_rptr, don't let the ellipsis gaslight you π
that's the tea! β this lil beauty comes from ./drivers/gpu/drm/amd/amdgpu, dated October 2026, and she's slaying in the Kernel API Manual section 9 πβ¨ππ¦ bye bestie, go read some pointers π«Ά
