Issue: For texture with multiple planes, the planes will point to the
same BO with the total size, so current vcn dt_size is incorrect.
(gdb) p/x *((struct si_resource *)(((struct vl_video_buffer *)out_surf)->resources[0]))
...
buf = 0x5555558daa30,
gpu_address = 0xffff800101000000,
bo_size = 0xa2000,
...
}
(gdb) p/x *((struct si_resource *)(((struct vl_video_buffer *)out_surf)->resources[1]))
...
buf = 0x5555558daa30,
gpu_address = 0xffff800101000000,
bo_size = 0xa2000,
...
}
This is because: in function static struct si_texture *si_texture_create_object(),
if (plane0) {
/* The buffer is shared with the first plane. */
resource->bo_size = plane0->buffer.bo_size;
...
radeon_bo_reference(sscreen->ws, &resource->buf, plane0->buffer.buf);
resource->gpu_address = plane0->buffer.gpu_address;
}
