TOS RAM test routine ?

[exxos]

@stephen_usher and / or @Badwolf

From what I can tell the normal memory routine of "own address test" and some other tests are normally done, but all but own address are skipped in this version. So I assume this is what TOS306 is doing.

I am also not really sure it is showing the proper amount of TTram as well.

EDIT:

This one may fix the RAM amount issue.. I think there was a "typo" in the RAM detect code :shrug:

No speed up with either this one or the 4.img.

Latter shows the correct memory count, though.

I think you're chasing your tail here. Go back to the original source, enable the cache and call it a day!

At the end of the day, hatari will not emulate the massive speed up of accessing TT-RAM in the 536 so I can only do a comparative. None is faster than the original so far.

That is odd as in Hatari 1.9.0 TTram test of 10MB is the same or a fraction faster than TOS306 now.

Cool beans.

It is enabled, has been for a while now.

It won't be faster than 306, but it's definitely not slower than 306 now. So don't know why you get those results as they differ to what I am getting here.

Yes, but I mean I don't think there's been any improvement with all the fiddling since, so IIYW I'd just go back to known good (albeit slow) starting position and only turn on the cache.

But that's just my tuppenceworth. I get nervous when a tweak doesn't do exactly what I'm expecting and I leave it in anyway :P

Does anyone have a single image file of PAK030 TOS ?

[stephen_usher]

Here you are...

[Badwolf]

Here you are...

After tweaking the version at 0x02, if I boot this in Hatari with the same configuration I used for Exxos' ROM image, it runs considerably quicker. Including the ST-RAM test, BTW.

Implies it's just performing fewer tests, to be honest.

Thanks.

PAK takes 2:25mins
ST536 TOS 2:24mins.

So I don't know where Frank got 24 seconds from . He must have a patched TOS which uses a larger block size.

PAK takes 2:25mins
ST536 TOS 2:24mins.

Wow, that's interesting -- and shows why Hatari testing for hardware issues can only take you so far!

EDIT: One thought, does your firmware allow caching of the TOS range?

ummmm. not sure. I know Anders patched stuff to cahe ST-RAM, but not sure if that included ROM.. Will have a look.

This is the routine it runs anyway.

Basically if TP_12 is enabled, it just jumps to testzon8 and just outputs the TTram amount without doing anything else.

Code: Select all

testzone:
        moveq.l   #0,d0
#if !TP_12 /* SKIP_RAM */
        move.l    memtaddr,d1
        cmp.l     memtbot,d1
        bcs.s     testzon8
        cmp.l     memtend,d1
        bcc.s     testzon8
        move.l    #ZONESIZE/4-1,d0
        move.l    d0,d1
        movea.l   memtaddr,a0
        moveq.l   #-1,d2
testzon1:
        move.l    d2,(a0)+
        dbf       d0,testzon1
        movea.l   memtaddr,a0
        move.l    d1,d0
testzon2:
        cmp.l     (a0)+,d2
        dbne      d0,testzon2
        bne.s     testzon7
        movea.l   memtaddr,a0
        move.l    d1,d0
        moveq.l   #1,d2
testzon3:
        rol.l     #1,d2
        move.l    d2,(a0)+
        dbf       d0,testzon3
        movea.l   memtaddr,a0
        move.l    d1,d0
        moveq.l   #1,d2
testzon4:
        rol.l     #1,d2
        cmp.l     (a0)+,d2
        dbne      d0,testzon4
        bne.s     testzon7
