Hi All

I need some assistance with the Shannon PCIe Driver compilation, I use these SSD's currently under Ubuntu 20.04 - 5.4.0-104-generic kernel, compiles perfect:

modinfo shannon.ko:

retpoline: Y

name: shannon

vermagic: 5.4.0-104-generic SMP mod_unload modversions

-- DRIVER Source ( I can share newer version from the vendor )

https://github.com/ottok/shannon-direct-io-pcie-driver

--- ESOS master branch

I downloaded the source for master, and build the ESOS system, I also enter the chroot env, and tried to compile the Shanon Driver, the source compiles fine, but doesnt link properly, the mod.o file doesnt get created, also the Module.symvers doesnt look right :

cat Module.symvers -->

Hi,

I don't have a straightforward answer... if you're in the chroot
environment, check your paths and kernel source directories specified.
Some of these third-party drivers use different make variables than
what's standard, so you may need to play a bit to get it built
correctly.
