surface.h: av1 substruct (picture + tile_group_entries[AV1_MAX_TILES=128] + num_tile_group_entries counter) picture.c: dispatch VAPictureParameterBufferAV1 + VASliceParameterBufferAV1 into surface->params.av1.*; call av1_set_controls in EndPicture path av1.h: minimal interface (av1_set_controls signature) av1.c: stub set_controls returning -1 with diagnostic; _Static_assert on v4l2_ctrl_av1_tile_group_entry size = 16 (Janet hygiene) meson.build: av1.c + av1.h in source list Verified on ampere with /tmp/test_av1.ivf via LIBVA_DRIVER_NAME=v4l2_request: v4l2-request: ampere-av1: vpu981 AV1 decoder at /dev/video4 + /dev/media3 v4l2-request: ampere-av1: av1_set_controls stub — Phase 2.1 will implement ... [av1] Failed to end picture decode issue: 1 (operation failed). [av1] HW accel end frame fail. [dec:av1] Error submitting packet to decoder: Input/output error Clean graceful failure — vpu981 probe works, dispatch reaches av1.c, stub returns ERROR, ffmpeg falls back to SW. No crash, no IOMMU fault, no kernel taint. Next: Phase 2.1 implementation of fill_sequence + fill_frame + fill_film_grain + fill_tile_group_entries (~700 LoC mirror of Kwiboo v4l2_request_av1.c, applying F1/F2/F3 implementation-time corrections from Janet review v2).
