Kimi-K3 enablement on gfx1250: - Opt-in AITER FlyDSL MXFP4 SiTU MoE backend (--moe-backend aiter_flydsl_mxfp4_bf16); SiTUv2 auto resolves to a8w4 on gfx1250. - Pin the KDA chunk kernels to num_stages=1 on gfx1250. - Route gfx1250 MLA prefill to AITER's Triton flash attention. - Keep gfx1250 on the Triton KDA decode; AITER's Gluon KDA decode is not yet validated there. On gfx1250 serve with AITER_FORCE_A8W4=1 and --kda-prefill-backend triton: AITER picks a8w4 there from that flag alone (a4w4 otherwise), and the auto KDA prefill picks AITER's Gluon chunk_kda, which fails to compile there.
