I have loaded kext by running below command in terminal.

sudo kextload mykext.kext

You wont be able to find the log file, because there is no such. You should use log utility in terminal: sudo log show

The output of this command is huge.

There are some built-in options that could help you to filter, like --last 5m, but I recomend to write all your driver messages with some stable prefix, like "MyDriver:", so you can use the log with | grep MyDriver:
