smi_stream_dev installing in wrong directory

[kng]

There seems to be some issue with figuring out where to install the .ko In /lib/modules I have 6.1.21+ 6.1.21-v7+ 6.1.21-v7l+ 6.1.21-v8+ Running kernel (arm_64bit=0): Linux raspi-sat2 6.1.21-v7l+ #1642 SMP Mon Apr 3 17:22:30 BST 2023 armv7l GNU/Linux Running the install.sh (current main branch) a few times results in this:

$ find /lib/modules|grep smi_stream
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/broadcom/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/broadcom/broadcom/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/broadcom/broadcom/broadcom/broadcom/smi_stream_dev.ko.xz
/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom/broadcom/broadcom/broadcom/broadcom/broadcom/broadcom/smi_stream_dev.ko.xz

While it should be in /lib/modules/6.1.21-v7l+/kernel/drivers/char/broadcom/ ? Inserting the module with full path works so the .ko itself is fine.

@kng thanks for the issue. please try the latest commit for the fixed outdir. couldn't reproduce the repetitive broadcom subdirs though... can you share the install log?

Hi, I'm experiencing the same issue with module being installed into wrong /lib/modules subdirectory. I have identical kernel versions installed as @kng listed above on my RPi4. I'm running kernel (output of uname -a): Linux pi4ant2 6.1.21-v7l+ #1642 SMP Mon Apr 3 17:22:30 BST 2023 armv7l GNU/Linux while having the same kernel versions and appropriate modules installed as @kng has: root@pi4ant2:/lib/modules/6.1.21-v7+/kernel/drivers/char/broadcom# ls /lib/modules 6.1.21+ 6.1.21-v7+ 6.1.21-v7l+ 6.1.21-v8+ I think the issue is here in the driver/install.sh script: https://github.com/cariboulabs/cariboulite/blob/000ecd7aaa17dae7644171ef5b83c92c894d89bc/driver/install.sh#L48C25-L48C25

That find (output_dir=$(find "/lib/modules" -type f -name "bcm2835_smi_dev*" -exec dirname {} \;) will output multiple modules subdirectories in case you've got multiple kernels installed, but the following copy command sudo cp -r ${ROOT_DIR}/$BUILD_DIR/smi_stream_dev.ko.xz ${output_dir}/ will only copy module to the first modules subdirectory from the list in output_dir. This happens to be in my case /lib/modules/6.1.21-v7+, while I'm running 6.1.21-v71+.

Moving the module manually to the correct modules subdirectory resolves the issue.

A potential solution might be limiting that find command only to an appropriate subdirectory of /lib/modules, e.g. KERNEL_VERSION=`uname -r` output_dir=$(find "/lib/modules/${KERNEL_VERSION}" -type f -name "bcm2835_smi_dev*" -exec dirname {} \;)
