Subject: Question about commit 8cf9926c537c (thunderbolt: Reset only non-USB4 host routers in resume)
Date: Thu, 25 Dec 2025 15:22:29 +0800	[thread overview]
Message-ID: <a6babdfa-a8ba-4e5e-82c2-0779a0943220@kylinos.cn> (raw)

Hi Mika,

Sorry to bother. I have a question about the above commit that I 
couldn't figure out, and I'd really appreciate it if you could help.

The commit message says: "There is no need to reset the USB4 host 
routers on resume because they are reset already."But aside from 
`nhi_probe`,

I haven't found where this reset occurs in the resume path. Could you 
please clarify where this automatic reset happens or the rationale 
behind it?


Thank you for your time.

Best regards,

jiayi
