Kernel configuration problems

Kernel configuration problems

[-- Attachment #1.1: Type: text/plain, Size: 2871 bytes --]

I'm trying to add a couple of drivers to the kernel in a Raspberry pi3 build.



I've got the passing of the config options working, but I'm getting warnings from the kernel build that the options are not being applied:





WARNING: linux-raspberrypi-1_4.4.50+gitAUTOINC+04c8e47067-r0 do_kernel_configcheck: [kernel config]: specified values did not make it into the kernel's final configuration:

---------- CONFIG_SND_SOC_MAX9768 -----------------
Config: CONFIG_SND_SOC_MAX9768
From: /home/gwilson/Qt/Qt-5.9.6/Yocto-build-RPi3/build-raspberrypi3/tmp/work-shared/raspberrypi3/kernel-source/.kernel-meta/configs/Scribe.cfg
Requested value:  CONFIG_SND_SOC_MAX9768=y
Actual value:

Config 'SND_SOC_MAX9768' has the following conditionals:

Dependency values are:


---------- CONFIG_MAX1363 -----------------
Config: CONFIG_MAX1363
From: /home/gwilson/Qt/Qt-5.9.6/Yocto-build-RPi3/build-raspberrypi3/tmp/work-shared/raspberrypi3/kernel-source/.kernel-meta/configs/Scribe.cfg
Requested value:  CONFIG_MAX1363=m
Actual value:     # CONFIG_MAX1363 is not set

Config 'MAX1363' has the following conditionals:
  I2C (value: "y")
Dependency values are:
  I2C [y]


My problem is that I don't understand why the options are not being applied.

For the MAX_9768, it depends on I2C=y which is true. I've run the linux kernel menu config and when I get to the Sound SOC support none of the drivers that require I2C support (i.e. 'select SND_SOC_MAX9768 if I2C') are displayed. I don't see anything else that would disable them, the other drivers in the SOC Kconfig that don't depend on I2C or that depend on SPI_MASTER are displayed.

The MAX1363 can be set in the menuconfig to 'm', but still won't set from the scc, cfg files.



Any insight into what's going on here would be greatly appreciated.

I can help with this ... but first, is this a configuration that I can
build myself ? i.e. what branch, what layers and what extra configs
would I need ?

Hi Bruce,

The full build is a Qt Boot2Qt build, so it includes some Qt stuff that isn't part of Yocto, but the kernel is just the linux-raspberrypi kernel. The one kernel that I'm getting in the build is 4.4.


Here is the reported build configuration:


Build Configuration:
BB_VERSION        = "1.32.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "universal"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "raspberrypi3"
DISTRO            = "b2qt"
DISTRO_VERSION    = "2.2.4"
TUNE_FEATURES     = "arm armv7ve vfp thumb neon vfpv4 callconvention-hard cortexa7"
TARGET_FPU        = "hard"
SDKMACHINE        = "x86_64"
meta
meta-poky         = "HEAD:df76669bdd70aa0d903c4211dde731221c7e756d"
meta-raspberrypi  = "HEAD:2a192261a914892019f4f428d7462bb3c585ebac"
meta-oe
meta-python
meta-networking
meta-initramfs
meta-multimedia   = "HEAD:b40116cf457b88a2db14b86fda9627fb34d56ae6"
meta-boot2qt
meta-raspberrypi-extras = "<unknown>:<unknown>"
meta-mingw        = "HEAD:1c2e155111dce94423cc227ea69f7f50f316c78e"
meta-qt5          = "HEAD:49e9d9a73b5c6e3d6eab88dc0005305e85b1a62d"
meta-sakura       = "<unknown>:<unknown>"

I've attached both my .bbappend and my .scc & .cfg files. The .bbappend also references a patch for another driver, but that is working correctly.


Just to be complete the path to the .bbappend & files directory is:


Qt-5.9.6

     Yocto-mirror                                                     # Yocto build mirror

Hi Bruce,

My Mail system sent my reply before I got done with the dir tree. Here is the completed tree:


Qt-5.9.6

                                       linux                               # directory that contains .bbappend
                                              files                         # directory that contains .cfg & .scc files

Hope this all helps.

Thanks,
