How to enable IIO sensor HAL and Sensor multi HAL for different sensors?

vick_chang — Mon, 29 Aug 2022 08:22:17 GMT

We’re porting Gsensor and Light sensor on A11, I tried to enable IIO sensor HAL for light sensor and use other HAL for Gyro sensor.

Hence, we may need Sensor multi HAL.

Did you have a guide for how to enable ?

IIO sensor HAL in NXP
Sensor multi HAL

==============================================

I have tried to add below in evk_8mq.mk

PRODUCT_PACKAGES += \

android.hardware.sensors@2.0-service.multihal \

android.hardware.sensors@2.0-service.multihal.rc \

android.hardware.sensors@2.0-nxp-IIO-Subhal \

and add below in manifest.xml

<name>android.hardware.sensors</name>

<transport>hwbinder</transport>

<name>ISensors</name>

<instance>multihal/</instance>

</interface>

<fqname>@2.0::ISensors/multihal</fqname>

</hal>

=====================================

And I get build errors:

checkvintf I 08-29 03:03:49 116 116 check_vintf.cpp:84] List 'out/target/product/evk_8mq/product/etc/vintf/': No such file or directory

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] files are incompatible: The following instances are in the device manifest but not specified in framework compatibility matrix:

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] android.hardware.sensors@2.0::ISensors/multihal

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] android.hardware.sensors@2.0::ISensors/multihal/

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] Suggested fix:

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] 1. Update deprecated HALs to the latest version.

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] 2. Check for any typos in device manifest or framework compatibility matrices with FCM version >= 5.

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] 3. For new platform HALs, add them to any framework compatibility matrix with FCM version >= 5 where applicable.

checkvintf E 08-29 03:03:49 116 116 check_vintf.cpp:554] 4. For device-specific HALs, add to DEVICE_FRAMEWORK_COMPATIBILITY_MATRIX_FILE or DEVICE_PRODUCT_COMPATIBILITY_MATRIX_FILE.: Success

INCOMPATIBLE
