lldb doesn't know what register set exists - if you do 'register read' you'll see that there are no registers. Maybe gdbserver doesn't implement the target.xml request (it's their packet definition! c'mon!)
Download the x86_64 target def file from http://llvm.org/svn/llvm-project/lldb/trunk/examples/python/ and load it in your .lldbinit file or on the cmd line lldb -O 'settings set plugin.process.gdb-remote.target-definition-file /path/to/def-file.py' > On Dec 4, 2017, at 5:56 PM, David Manouchehri via lldb-dev > <lldb-dev@lists.llvm.org> wrote: > > My apologizes if this is mentioned somewhere already, couldn't find > anything on the subject; it seems that gdb-remote doesn't work very > well (or at all in my tests) with gdbserver. > > Tim Hammerquist was also able to reproduce issues when attempting to > use gdb-remote with gdbserver.
