It seems missing DMA & HDMI moudels, it's any way to build DMA as a kernel moudels?

now I have successfully compile the i915 module, keypoint is to clean befor every rebuild and build under modules root directory. make M=drivers/gpu/drm/ CONFIG_DRM_I915=m clean make M=drivers/gpu/drm/ CONFIG_DRM_I915=m modules but now i'm faceing another issue, that is i915.ko modules dependency. when i build i915 modules, it comes along with drm.ko drm_kms_helper.ko drm_panel_orientation_quirks.ko I have try to insmod it, but shows error,is it have dependence modules i'm not build? sudo insmod /lib/modules/i915.ko sudo insmod /lib/modules/drm.ko insmod /lib/modules/drm_kms_helper.ko

I'm just J3455 want to enable hw transcoding, i have try to build i915.ko with GPL Source and ToolChain, but shows "Module.symvers" is missing. To use SA6400 insteed of DS920+ because SA6400 is kernel 5.10 so it can enable BBR and FQ.

BBR can cooperated with Queuing Controlle like Fq or Cake. Incase someone need it, there is Fq/Fq_Codel/Fq_Codel/Fq_Pie/Cake models

Do you know how to build the i915 ko? I have J3455-ITX, when I build it come out this error
