software OS4   software OS4 : Sam440ep_setup 1.3 released
   posted by m3x on 7-Feb-2012 0:04:43 (5898 reads)
Sam440ep_setup is a little utility to optimize performance on your Sam440ep board (mini-itx and flex versions)

What's new:

use a more aggressive instruction cache speculative prefetching setting.
This allows a faster execution for some software, for example the following
Blender speed test increased performance by 10%-20%:


bldyn -b projects/bricks_and_water_plugin.blend -o ram:pool -F JPEG -f 0

As a sidenote some values returned by Ragemem are incorrect (MIPS) or lower
(L2 cache read64/write64) when this setting is enabled.
To disable this setting, add NOCCR argument to the command line.

@m3x:

is it possible to enable UDMA for the HDD when loading the kicklayout-modules to speed boot up a lot?

Just because of the recent benchmarks...

RAGEMEM v0.37 - compiled 11/06/2010

CPU: AMCC PPC440EP 1.3 @ 666 Mhz
Caches Sizes: L1: 32 KB - L2: none - L3: none

Copying AKsack.wav to RAM: (via DOS) happens under 2s (counting seconds in my head).
How could I time the copying more accurately?

UPDATE:
uptime
copy...
uptime
-script shows that copying happens below 2s
need more details ... want to beat those PowerMacs ...

@Cool_amigaN

You may try with this tool:

http://www.os4depot.net/share/development/edit/kickedit.lha

Just copy the current kicklayout with the "Clone" button in the Kicklayout box (to have a safe configuration to boot from in case something go wrong) and remove the unused modules.
On a standard Sam440ep without any additional PCI card you can remove the following from the kicklayout:

3dfxVoodoo.chip
it8212ide.device.kmod
lsi53c8xx.device.kmod
sii0680ide.device.kmod
sii3112ide.device.kmod
sii3512ide.device.kmod
siliconmotion502.chip
uhci.usbhcd

copy AKsack.wav ram:
echo $_RunTime

BTW: where I can download that wav file from ?

To enable UDMA in U-Boot, the rewrite of the 3114 driver is needed (it's not a trival change) and I lack the time for this...

@m3x

Link to the wav can be found for example here:
http://amiga-news.de/en/news/AN-2012-02-00011-EN.html

And thanks for the timing tip.
The copy took 1.54s. part-RAM
And 3.0s part-part
Snappy...
(but did not outperform those PowerMacs. )

2D benchmark:
http://hdrlab.org.nz/benchmark/gfxbench2d/OS/AmigaOS/Result/605

UDMA for UBoot .... sounds like we need a bounty ...

Sounds good! Count me in with 20 EUR!

How much money M3X expect to do this Part?

I'm quite sure M3X said he lacked time (not money) for doing UDMA for UBoot.

@Troels

When there's some money to be made, it would be easier to find time.
(at least it's true for me)
