Yep. > I think the next step is to add No-Execute (NX) support to GNU Mach. Oh, that could be useful indeed. The good news is that the user/kernel interface already exists: VM_PROT_EXECUTE, it's just not implemented yet within gnumach.. > I'd also suggest adding support for more then 4 GB of RAM to GNU Mach, but > considering that it does not even support more than 1 GB of RAM yet, I'd fix > that before trying to support more than 4 GB of RAM.

It'd be probably better to just support 64bit processors, which will immediately bring support for more than 1GB of RAM. Support for more than 1GB of RAM on a 32bit machine is really clumsy. Linux does it, but it's really a pain. > Also important IMO is ACPI support, which will help when implementing > SMP support. Well, the ACPI part for SMP shouldn't be so hard ; SMP itself will be.
