Re: Current kernel with http://gnats.netbsd.org/39965 and pmap patches

Ok, some good news mixed with bad...

The ATARITT kernel does not load, regardless of if anything is plugged into a serial port or not. Just a blank screen after running loadbsd.ttp.

But the BOOT kernel does boot. And I successfully installed the sets via CD-ROM! The install completes successfully, but when the system is rebooted I just get "Halting..." after the memory test. This is probably from the very first stage of the netbsd bootloader but I'm not really sure. I didn't try doing a complete zero of the disk before the install -- it's conceivable that might help.

One issue that is probably minor... When "/bin/sh MAKEDEV all" is running, I get "df: not found". This does not stop the install though. Probably the df binary just needs to be dropped onto the sysinst floppy.

Major diffrences between ATARITT (or FALCON) and BOOT
which might affect pmap changes are:
- kernel size (due to many MI options)
- options SERCONSOLE
- options RELOC_KERNEL
- options MSGBUFSIZE

I guess the last two items require some special handling
during pmap initialization. (conversion between PA and VA etc.)

I have not checked how RELOC_KERNEL works, but it looks
Sysptmap_pa should be adjusted for it:

I've put new kernels from the latest sources
(which include ffs_update() fix) with this patch:
