Intel AMT/ME Deduplication #72

Closed texhex closed 5 years ago

texhex commented 6 years ago

As @datagutten found out, there are several (not directly related) devices that share the same AMT/ME engines which would make it possible to deduplicate those downloads to a common folder. E.g.:

The pull request #71 with these changes will be accepted, but only the changes for the Folio devices will have their ME shared, all others will be rolled back. That's because I fear that, if an update to ME files in the shared folder "x360 1030" is applied, no operator is aware of the fact that this will also have an effect on a ZBook.

Clearly, this deduplication has advantages in terms of storage and update effort, but for any operator not aware of the dependencies I fear this to cause confusion.

Maybe we could find one common indicator between those models that share the same ME version. Maybe the chipset name? If so, we could create a folder based on that, e.g. "Q45 ME-AMT". But I'm unsure if this would be easily understand for the operators.

When checking for a common indicator, we can use the list in HPSBHF03571 and which devices are listed as getting their update from Softpaq #82486.

The only common indicator I found is that they all seem to use an "Intel 7th generation processors", but I doubt that this ME will match any iX-7xxx.

Also, except for the ZBook, HP does not mention the chipset.

This issue was now opened for several weeks, without any response. I will close it within the next days if not someone comes up with an idea how to solve this.
