Hi all, I am a CS professor (and, newly, a second-time contributor). I have been using qemu in my courses for over a decade, especially a course that asks students to write major pieces of an OS kernel from starter code.
I have some patches, originally from Austin Clements at MIT, that I have found useful over the years and that may be useful to others. It would also be nice not to have to build a custom qemu each semester. I have cleared upstreaming these with Austin, the original author. This patch set adds an 'info pg' command to the monitor, which prints a nicer view of the page tables. A project in my graduate OS course involves implementing x86 page table support, and my students have found this helpful for debugging. Thank you in advance for your time, Don Porter
