Amigaworld.net News   Amigaworld.net News : AEROS for Pi beta 3 available on SD-card
   posted by phoenixkonsole on 9-Jul-2013 9:41:59 (2510 reads)
Yesterday i finished beta 3 of AEROS for Pi (a AROS hosted distribution based on debain (for now)). Upload for registered users is slowly progressing - will be ready today or at latest tomorrow.

http://www.youtube.com/watch?v=gfgJcJcV7HY

Click READ MORE --->


New in the beta 3 are:
Some new app with Icons and icons for already installed apps as follows:
Gimp 2.8 (yes i used it to make some icon on the pi... ; ) )
Audaciuos (Winamp like audio player)
LibreOffice
Dillo (brower which starts instantly and is ok for Amiga releated websites)
Netsurf (better compatibility and somewhere between Dillo and Midori in terms of performance)
Midori
VLC (don't expect wonders! Remember to buy codecs from the raspberry guys on raspberry.org)
DOSBOX (damn feels like on ATOM systems ; ) )
E-UAE (yes but no AROS68k yet - will follow with next version together with PUAE)
Leafpad (Text Editor, lightweight)
SCUMMVM + Beneath a stell sky + Flight of the Amazon queen
TUXPaint - nice painting app for kids with stamps and nice effects
and more...

Remember you can access everything mentioned above(and more) alternatively with a right click on the black task bar.

I found some applications to be very responsive and some which start instantly, even on a relative slow sd-card. If you know alternatives to some apps feel free to tell me those ; )

All in all AEROS for Pi (even if based on debian) is already quite leightweight.
Debian + AROS consume in total 68MB of RAM whereas 32MB of it are "reserved for AROS" which again shows 28MB free of 32MB which means in total AEROS need 40MB RAM ; ) Not bad. WICD Networkmangaer consumes 11MB of RAM and will be replaced with an better alternative.

Slitax is an good alternative to debian. The whole Linux part could be loaded into 30MB of RAM. This means everything being loaded to RAM and so no SD-banging.

To make it a bit user-friendly you can now access raspi-config via icon.
With this tool you can expand the partition to the whole free space on your sd-card and configure overscan and other Pi related things.

Linux windows have now the close icon on the left side as AROS apps.

Good work!

However, seems to be too slow to be really useable (application loading, GFX redraw etc.).

How fast is DosBox on Pi? Could you try DHRY2OD benchmark (See post 57)?

Ok will try it.

Remember:
This is arm soft float. Hard float will be 10-20% faster.
Raspi's GPU isn't supported for 2D accelerated desktop stuff.
This will change with Wayland/Xwayland -> and this fixes the problem.

The A8 cortex in the Efika MX matches the SAM440 @733 under debian.
The pi's ARM11 cpu matches more a Pentium II 200. Maybe 400 when overclocked.

I will posts some results in a few minutes.

Ah, that explains not so fluent GFX. Then, it wasn´t that bad. Maybe with faster disk access, it could be useable. As I read in some book about PC hardware (published in 1991): fast GFX and fast HDD are most important factor, if you want built computer with "fast" feeling. True even in 2013.

According to some benchmarks under RiscOS is Pi comparable to Pentium II 300-350 MHz, still only half as fast as SAM440.

Thanks. It seems this DosBox port doesn´t like cycles=max setting. 0.09 DMIPS is in 8 bit territory (roughly equal to fixed setting of 60 CPU cycles).

Hard to say, what fixed CPU cycles settings would be ideal. Maybe somewhere between 1500 and 2500 CPU cycles.

DHRY2OD uses all possible optimalisations, DHRY2ND uses no optimalisations.

Again, thanks for your time.

0.23 DMIPS. That is exactly 8088 4.77 MHz (or 150 CPU cycles). As I wrote, it seems cycles=max setting is not ideal for this port of DosBox, fixed setting could give better results, but it is hard to fine tune desired value (eg. I run some of my games with good music and increase CPU cycles by ctrl-F12 until sound starts to be wrong).

Patiently awaiting a version for Ouya if that is ever possible. Thanx

Sorry I can't support a competitor. It is against my nature ; )
