Remove #ifdef'ed out hp300 specific stuff. Remove leftover "last kernel PT page" settings derived from hp300. Whilehere, also remove VM definitions for obsolete COMPAT_HPUX stuff. All hp300 machines has RAMs at a region from the highest address i.e. 0xFFFFFFFF to smaller address (as HP claims "it's the MSB first"), so kernels have to prepare PA==KVA mappings as the "last PT page" to guarantee the running kernel works both before and after the MMU is turned on. For such a special mapping, we have to set up necessary segment table and page table during early startup, in pmap_bootstrap() invoked from locore.s. On the other hand, NeXT machines have RAMs at a region from 0x40000000 to below (i.e. to larger address) so we still need a PA==KVA mapping. However currently NetBSD/next68k just uses the transparent translation registers to achieve the PA==KVA mapping, so unlike hp300 we don't have to prepare special segment table and page table for it. Note many other m68k ports (like luna68k, news68k, x68k etc.) have RAMs at a region from 0x00000000 so usually we can assume PA==KVA and don't have to bother to prepare such speicial mappings. No user visible changes (except now freed wasted pages for the tables). Tested on my NeXTstation slab. |

NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ freenode.
