Thanks! I was in fact eyeing the x86_64 BSP targets. I aim to understand
RTEMS more from a user's perspective - likely using the POSIX API to
build some toy projects and whatnot.

As time goes on, hopefully I'll be able to contribute smaller patches -
does the RTEMS tracker have tickets marked with any keywords indicating
the easier tickets to tackle? (In the spirit of how Github projects tend
to have "good-first-issue" labels for new contributors.)

Patch and screenshot sent to you. Cheers!
