Re: GNSS support for Qualcomm PCIe modem device

[Muhammad Nuzaihan <zaihan@unrealasia.net>]

Hi Slark,

I just implemented it in the wwan subsystem since it works for me (even 
without flow control). I wanted to port it to use GPS subsystem, 
however, debugging in GPS subsystem is too troublesome, especially when 
the driver crashes.

Unless i can have some VM with direct access to the Quectel hardware so 
i don't need to keep rebooting my machine if it crashes.

For now, i am getting GNSS/NMEA data from Quectel with MHI wwan 
modifications.

Regards,
Zaihan
