You can set ESP_RTOS as hwthread. Then when gdb connects, you can execute info threads to see individual cores. And you can switch to the core by thread 1  or thread 2

Thank you! Could this be put in the official ReadTheDocs as well?

Since this is not a common use case for our users, I am not sure where to put this information.

It is mentioned in the official document, section 20.7. https://openocd.org/doc/html/GDB-and-OpenOCD.html

Thanks for the verification. I am closing this.
