Generate framework compatibility matrix from fqnames

README.md

Generate framework compatibility matrix from fqnames

• Download these 2 files
• Compile AOSP without fcm from stock and wait for check_vintf to error out
• Delete Python prefix from all lines (e.g. checkvintf E 06-24 00:30:22 49120 49120 check_vintf.cpp:554])
• Paste the result in fqnames.txt
• Launch the script

fqnames.txt

# Add here a list of fqname
# You can get it if you try to build AOSP without a fcm
# check_vintf will print a list of needed entries
# This currently works with AIDL and HIDL
# Here an example from Xiaomi SM8150 common tree

This is my fqnames, i think it's formated properly https://nekobin.com/nevutivuvu

Should be fixed now

Hey, it doesn't work when there is aidl type entry
example: android.hardware.power.IPower/default (@2)

ye. I too faced it

Hey, it doesn't work when there is aidl type entry example: android.hardware.power.IPower/default (@2)

Remove those values with braces . It should be android.hardware.power.IPower/default

Hey, it doesn't work when there is aidl type entry example: android.hardware.power.IPower/default (@2)

The ouput is:

<hal format="aidl" optional="true">
    <name>android.hardware.power</name>
    <version>2</version>
    <interface>
        <name>IPower</name>
