-PROBLEM DESCRITION
I’ve compiled a new uvcdriver.ko
https://github.com/Giuliano69/uvc_driver-for-Quanta-HD-User-Facing-0x0408-0x4035-
but I’m facing this error once I try to install the module
giuliano@Astra2A:~$ sudo rmmod uvcvideo && sudo modprobe uvcvideo
modprobe: ERROR: could not insert 'uvcvideo': Exec format error
and dmesg shows:
[25961.151982] usbcore: registered new interface driver uvcvideo
[26323.125534] usbcore: deregistering interface driver uvcvideo
[26323.189294] uvcvideo: disagrees about version of symbol module_layout
Googling on internet, the problem seems to happens when we want to use a module compiled for a different kernel version.
These are the TWO modinfo from the old and new uvcvideo modules https://pastebin.com/tSj8Exm6
Basically
OLD module: vermagic: 5.15.0-56-generic SMP mod_unload modversions
NEW module: vermagic: 5.15.64 SMP mod_unload modversions
-HOST CONFIGURATION
I’m using this kernel
giuliano@Astra2A:~$ cat /proc/version_signature
Ubuntu 5.15.0-56.62-generic 5.15.64
BUT on the closest kernel I found on Ubuntu archive is 5,15 and seems to be different: https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git/linus--linux/refs/tags
to allow Eclipse to compile the kernel, I had to pass this commands:
scripts/config --disable CONFIG_SYSTEM_REVOCATION_KEYS
scripts/config --disable SYSTEM_REVOCATION_KEYS
scripts/config --disable SYSTEM_TRUSTED_KEYS
the kernel is compiling without errors and the uvcvideo.ko is produced
-kindly ASK
-WHERE cane I found an Ubuntu kernel SOURCE to exactly match the version I’m running ?
-HOW can FORCE the uvcdriver.c to match mi kernel version ?
-Have I got OTHER ways to make the kernel module I’m compiling, match my running system ?
