FS_xxx ops in libsa is also used to load secondary bootloaders (not a kernel that might require module info) on several ports, including x86, and I guess in that case ioctl or the "fsmod" variable is not necessary as before.

The '020 saves the mid-instruction state for some faults (as well as the actual fault reason) so they can be recovered. (Just don't continue on a cpu with a different mask level.)

Re: CVS commit: src/sys/arch/x68k/stand/boot_ustar
Dennis, while the MC68020 did not have an MMU onboard there where Motorola PMMUs out there (MC68851). In the beginning there was an FPGA solution that emulated a subset of the MC68851 PMMU via the Coprocessor interface. Later when the PMMU became available it was also used in designs. E. g. I put an XC68851 (pre-production sample) into my Mac II around 1988 and could run A/UX (or whatever it was called). Early versions of NetBSD did work too. So there was some 'common' MMU support for the '20 via the PMMU coprocessor support. Sun had it's own MMU, though. The MC68851 came late to the market, that's probably the cause why so many non-Motorola solutions existed for the 68020.

That generic x68x requires a 68030 makes sense since that's the first CPU where the code can count on knowing how the MMU works. A 68020 would have a manufacturer-specific MMU, while for the 68010 there is only sun2. There is no reason to restrict the instruction set to that of the 68000 in any case since NetBSD won't run on that. I once had a 68000 board that ran a 4.3 BSD kernel, but it was a 4.3 BSD kernel with all the process scheduling hacked out so that it ran exactly 1 compiled-in user space process, without memory protection. I used it as an ntp server. Dennis Ferguson

dennis wrote: That generic x68x requires a 68030 makes sense since that's the first CPU where the code can count on knowing how the MMU works. Well, it's not a guess but the design of NetBSD/x68k. A 68020 would have a manufacturer-specific MMU, Note there is Motorola MC68851 PMMU for 68020 and some hp300 and mac68k machines have it (and we support them). There is no reason to restrict the instruction set to that of the 68000 in any case since NetBSD won't run on that. In this prinary bootloader case, 68000 was intended to be supported to print wrong MPU warning for users, while it isn't implemented yet. Actually X68000 EXPERT (emulated by XM6i) can run the primary boot_ustar in NetBSD/x68k 6.1.3 boot floppy and it loads the secondary boot. (though it fails in the secondary boot without proper warning yet) Anyway, AFLAGS+= -Wa,-march=m68000 -Wa,-mcpu=m68000 works both with gcc 4.5 and 4.8 (and same binaries are generated) so I'll put it back to the Makefile. --- Izumi Tsutsui

Here is my guess: - NetBSD/x68k supports only X680x0 machines with MC68030 and higher processors. - Normal X68000 machines (i.e. all X680x0 except X68030) have MC68000, so 030 accelerators are required for the X68000 models, i.e. XVI, SUPER, EXPERT, PRO, and ACE. (BTW the normal X68030 has MC68EC030 so users also have to replace its CPU to with MC68030 to use NetBSD/x68k) - On the other hand, probably early x68k developers considered that some stupid users could try to boot NetBSD/x68k on X68000 without 030 and bootloaders should have some sanity checks. - All primary bootloaders except the boot_ustar have 020 checks: http://nxr.netbsd.org/xref/src/sys/arch/x68k/stand/boot_ufs/boot.S?r=1.10#65 but the boot_ustar (for boot floppy) doesn't due to size restriction, so -mc68000 was intentionally specified for it: http://mail-index.netbsd.org/source-changes/2001/10/01/0037.html - However, the secondary boot doesn't have proper 68000 check (yet?): http://nxr.netbsd.org/xref/src/sys/arch/x68k/stand/boot/srt0.S?r=1.2#60 Nowadays all (aged) X680x0 geeks know it won't work on normal X68000, so probably it's safe to remove it. (I'm not sure if -mc68000 actually emits different code though) Note a possible change in gcc 4.8 that causes this trouble is: http://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/m68k/m68k.c?annotate=173256#l482 I guess that gcc 4.5 passes only explicitly specified -m680x0 (which seems equivalent to -march=m680x0) options (i.e. as(1) will use its default -mcpu), but gcc 4.8 always passes both -march and -mcpu per the specified -m options to gcc(1) (m68k_cpu_entry is always set?) so passing only -Wa,-m[c]680x0 on gcc 4.8 makes as(1) complain arch vs cpu mismatch. That's the reason why passing both -march=m68030 and -mcpu=m68030 solves build failure on mvme68k 060 kernels with both gcc 4.5 and 4.8. In this boot_ustar case, passing only -Wa,-mcpu=m68000 fails with gcc 4.5, and passing only -Wa,-march=m68000 (or -Wa,-m68030) fails with gcc 4.8. --- Izumi Tsutsui

I'm pretty sure NetBSD could never run on a 68000 since the 68000 had no memory management unit. The 68010 and 68020 didn't have memory management units either, but Sun did proprietary MMUs for both (that's sun2 and sun3, respectively) and I think other companies may have done MMUs for the 68020. The 68030 was the first CPU in the series to come with an MMU built in. That generic x68x requires a 68030 makes sense since that's the first CPU where the code can count on knowing how the MMU works. A 68020 would have a manufacturer-specific MMU, while for the 68010 there is only sun2. There is no reason to restrict the instruction set to that of the 68000 in any case since NetBSD won't run on that. I once had a 68000 board that ran a 4.3 BSD kernel, but it was a 4.3 BSD kernel with all the process scheduling hacked out so that it ran exactly 1 compiled-in user space process, without memory protection. I used it as an ntp server. Dennis Ferguson
