Efika + MOS 2.1 = Awesome!
« on: September 14, 2008, 02:38:46 PM »
Hey Folks,

I got MorphOS 2.1 running on my Ekika yesterday. I looks like they fixed all the stability issues! I've been running all day with no crashes at all, Its pretty awesome. I havent tried the sound out yet though.

Couple of questions:

Whats a good dock/startbar program for MorphOS? I suprised that it doesnt come with one.

Has anyone figured out how to use graphic card memory as regular Ram yet? :-D  Its funny that my 9250 has the same amount of ram as the Efika.

Visit the "Objects" menu of Ambient.

AFAIK it is not yet possible, maybe with a later update. Would be very useful, though. Think of those times as you could fall back to Chipmem when you ran out of Fastmem.

You have Ambient panels, check the Objects menu.

Don't bet on it.

Hey, Thanks for the replies.

I've got panels now. I dont think I ever would have found that without asking!

I just tried the sound out. Its a pretty weak signal. I might have to hook it to a pre-amp or booster of some kind. I'm also getting noise from the harddrive as well. It sounds just like the noise I used to get when I had my A1200 hooked up to a Hi-fi.

I guess that makes it a pretty real Amiga experience :lol:

It would be possible indeed, but reading gfxcard memory is typically really slow.

To get an idea how slow it would be run "memtest vmem" (from shell). The 'verify'-speed is the readspeed.

Relatively it'd be much slower than falling back to chipmem on an amiga.

It doesn't seem to be slow compared speeds on real Amiga ;) I guess it would be big help in EFIKA's situation still...

VRAM storage device is (was?) possible on Linux, it should be on MOS?
Then at least ENV: could be assigned here I guess.

All this to store a few kB from Env:? :)

There's lots of similar patches in Aminet :) http://aminet.net/search?query=add+mem
Maybe someone makes little 3rd-party patch ;)

58 MB/sec. on my ancient R7500 compared to the quadruple in regular memory. This should give a better relationship on any newer Radeon which means it is at least in speed regions or even ahead of swapping to the harddrive. Should be considered though.

No way. That must be write speed. Even my Pegasos2 with Radeon 8500LE only does 37 MB/s read.

I confirm strong noise related to hdd activity as well as to gfx activity (e.g. Songplayer with vu-meter (bars) is almost unuseable due to noise.).
The overall audio out signal strength is not too weak (ccheck the Mixer settings).
I'll experiment a bit with better shielding next weekend (when I also get a new gfx card for my Efika) - I hope to get the noise reduced by that.
But aside from the sound issues (which seem to be hardware related) I confirm, that the Efika with MorphOS 2.1 is quite some big fun!

Anyway. It is read speed:

Ram Disk:> memtest vmem
Video memory testing locks the bitmap while testing, please wait patiently...
Allocated memory at 0xea551000 -> 0xebe50fff, 26214400 bytes
Writing 0x00000000... 210 MB/sec.
Verifying 0x00000000... 58 MB/sec.
Writing 0xffffffff... 217 MB/sec.
Verifying 0xffffffff... 58 MB/sec.
Memory is ok!

[EDIT]

Just to clarify: This is a result from EFIKA system?

[/EDIT]

Heh, it's nice to be wrong here :-D Or alternatively something is screwy with memtest. I seem to remember some very poor read performance (more like 14MB/sec read).

If this is true, I guess it might be worth looking into this, then.
