All, The latest version of L4 (from CVS) and probably earlier ones, check for the debug extensions. Does it actually use them? I ask this since Bochs, does not set the DE bit in the CPUID or support these extensions.
I have done a search for usage of DRx (where x is 0-7) in the source, but couldn't find any references. Is it safe to just remove the check for DE?
In Hazelnut we have no references to dr4 and dr5. Checking for the DE flag should therefore not be necessary.
I'm also trying to run Hazelnut under bochs.
Luke, will you let me know if you have any success?
