The "01_modem-quectel.patch" extends the quectel:plugin to provide firmware
setting status during the FW upgrading process.
EM120/160 PCIe modules have been already supported without this patch.
I got the confirmation from Quectel engineers about the above.
For the regression test, we found 2
Before I was relying on the information presented here and the changelog
in the upload to consider regression risk. Today I reviewed the patches
in more detail expecting to find what has been described. What's going
on in 01_modem-quectel.patch? This says "add support for EM120/160 PCIe
modules"
Hello, is there anything needs me to provide for moving to the next
step?

OK, so you currently have nothing in your Test Plan to verify this part
of the changes you're proposing? Please either fix the Test Plan, or if
testing this is impractical for some reason then we can discuss that and
decide what mitigation might be appropriate, but in this case the
omission and
By investigating the mentioned patches directly, the existing behavior
should not be changed:
* The patch for Quectel EM160 4G
There is only one patch, all changes are for the Quectel modems.
* Patches for Foxconn T99W175
There are 5 patches,

Agreed, but I would expect SRU information against every change being
made, that would then receive
How do you intend to verify that (3) has worked correctly?

Ok. For clarity, my understanding of these patches are that they do the
following things:
1) Add a feature to ModemManager to support uploading firmware to these modems
2) Increase a timeout that was found to be insufficient when doing a firmware
update
3) Add a bunch of mappings from

Title:
Support manual firmware upgrading
These patches are used for newer Foxconn/Quectel modems :
* whose drivers are using the WWAN subsystem in the kernel 5.13. ( this OEM
project uses customized kernel )
* communicated to the ModemManager service via the MBIM protocol
These patches will not be used if the modem can't meet the above
Applying these changes should have no risk:
* These changes are only for specific modems.(Foxconn and Quecktel)
* These changes are used when the platform's vendors do the firmware upgrading
for specific modems "manually".
We can try to find other modems then provide the regression test report
Is there a risk that applying these changes will regress the behavior of
these modems on systems which have NOT applied the firmware updates?
Can the testcase include a check for this?
