I'm not sure about "remote debugging" but the commit I'm referring is titled

I noticed that or1k entry is missing in gdbserver/configure.srv until gdb 12.

I guess git has the answer:

$ git tag --contains 4933265c3f71b9134363d0c05f09542d5cc677f4
binutils-2_38
binutils-2_39
gdb-12-branchpoint
gdb-12.1-release

Best regards,
Romain
