Hello,
Our iMX8MP SoMs (Verdin and Toradex SMARC) fail to boot after
commit e0203ddf9af7 ("media: verisilicon: Avoid G2 bus error while decoding H.264 and HEVC").
On rare occasions, it's still able to boot.
It fails after having registered g1 VPU, probably when it tries to
register g2 VPU.
Ming: Any ideas on how to proceed here?

This is quite a nasty bug you triggered here! I think the issue is that
the newly added imx8mq_vpu_shared_resources[] is of type __initconst
where as it should be __initconst_or_module. You can test this
assumption if you switch from a module [M] build for the hantro_vpu
driver to a builtin [x] build.

Marco

I will correct __initconst to __initconst_or_module.
Thank you for pointing out the issue.
