Surfaced during iter7 Track F research: the campaign target hardware
is Rockchip RK3566 silicon (PineTab2). The hantro driver attaches
via the rockchip,rk3568-vpu DT compatible because the RK3566 silicon
is close enough to RK3568 to share that variant. The proper RK3566
mainline driver target (rkvdec2 / vdpu346) has no kernel support yet
— Christian Hewitt's patch series LKML 2025/12/26/206 is unmerged.
Updates the two src/ comments that called the hardware "RK3568":
- context.c: hantro-vpu device-init S_EXT_CTRLS comment now reads
"via rockchip,rk3568-vpu DT compatible (covers RK3568 and RK3566
— PineTab2 silicon — since they're close enough)"
- h264.c: DPB pic_num discussion ends "...never surfaced on PineTab2
(RK3566 via hantro/rk3568-vpu)"
Not a correctness change. Compiles + decodes identically. The
update matters for upstream submission accuracy (bootlin/Rockchip
maintainers will care which silicon the campaign tested on).
