Intel DSP platform drivers are used by many different devices. For user space to differentiate them, ASoC machine drivers may use the DMI info (vendor-product-version-board) as card long name. Possible card long names are: DellInc.-XPS139343-01-0310JH ASUSTeKCOMPUTERINC.-T100TA-1.0-T100TA Circuitco-MinnowboardMaxD0PLATFORM-D0-MinnowBoardMAX ...
And user space can define configuration files like longname\longname.conf for a specific device.
Do you mean a file name containing a backslash? I didn't find the relevant code in your patch...
No, the file name doesn't contain a backslash. It means we're using the card long name as both the directory name that contains the UCM config file and the name of the config file itself. E.g. for the laptop Dell XPS 13, UCM will try to find a directory "DellInc.-XPS139343-01-0310JH", and then find the file " DellInc.-XPS139343-01-0310JH.conf" under the directory. If it cannot find the this file, it will fall back to open file "broadwell-rt286.conf" under directory "broadwell-rt286".
Ah, a backslash as on DOS. Use a slash for Linux instead :)
