I carried out both of those in fullscreen mode - and the graphic glitch is no longer present. I assume safe to add this to my startup-sequence now.

Not yet
We still need to find out what's exactly causing the problem.... could you please unset both env vars and use only this one instead?

setenv Picasso96/DMABLFromVRAM 0

I tryed to create a drawer in envarc called Picasso96 with file DMABLToVRAM with 0 value in, but it doesn't cure the problem, if you launch the game in full screen 1920x1080 the problem doesn't appear, but if you try to launch the game in window mode or in full screen in some other resolution the problem occur, at the moment i don't know if the problem is in Picasso96 specific to sam460 or in the game

What happen if you set Picasso96/UseDMA to 0 ?

BTW you just need to enter the following line in the Shell before running the game:

setenv Picasso96/UseDMA 0

or

setenv Picasso96/DMABLToVRAM 0

(no need to create a drawer in ENVARC: etc...)

If it works correctly after setting DMABLToVRAM to 0, try increasing the value by steps of 256, until it show the problem again, and report here your finding, thanks !

Should be a news item with a link to a OS4Depot upload.

The agreement with Hans allow us to release the driver only to AmigaOne 500 / Sam460ex owners

If you really want to try a PCI gfx card on your Sam440ep, I suggest you to find a (rather rare) Radeon 9000, with 128-bit RAM bus.

This is the fastest gfx card you may currently use on a Sam440ep (mini-itx or flex model) and it's as fast as the onboard M9 in 3D speed, while Radeon 9200 or 9250 are way slower.

Re: Interrupts across a PCI Bridge

The two other devices have much lower IRQ numbers, in the 40s, I think it was - the 23882 has 66!

66 is the right value for the PCI slot IRQ on a Sam440ep (INTA)
The C2388x use edge or level triggered IRQ ?

On my Cx2388x boards, I get nothing.
I think that this is because the C2388x board uses a PCI bridge, as it's a multi-function card. My understanding is that the interrupt for the CX2388x chip may be INTA# as normal, but by the time it's crossed the bridge, it could be any interrupt.

Are you sure the board use a PCI bridge ?
Could you provvide a Ranger screenshot showing the PCI devices tree on your Sam440ep ?

Please send me a detailed explanation of what happened, what's the current problem, and if needed, photos of the damaged area, at the following address: mtretene at acube-systems dot com

I'll take a look at it when back in office.

Do you have U-Boot 1.3.1d ? In case, can you try reverting back to the 1.3.1c version ?
Have you installed Sam440ep_setup from OS4Depot ?

Modify kicklayout inserting the following line:

MODULE Kickstart/sam460sata.device.kmod

move and rename DEVS:sam460sata.device to Kickstart/sam460sata.device.kmod

Re: Public screen closing bug in OS4.1

I cannot replicate the problem using AOS4.1 beta (upd2 + daily updates)
OWB (3.32) correctly close the screen when the last Ringhio notification fades away, so the bug seems to be fixed.

I noticed this in your comment:

SPR[0x03b2] already set... skipping

There was a bug in my code, this means on your machine the first patch wasn't applied, you may still suffer for low L1 cache write speed.

Please try again with the new 1.1 version I just uploaded on OS4depot:

@ChrisH

Crisot is right, the patch improves only read performance, which has near zero impact on 3D games.
You may noticed some improvments in some SDL games, emulators and amicygnix.

Anyway later today or tomorrow we'll publish a PCI update utility on ACube website which will improve write performance up to 30% (around 64 MB/s on the M9 chip) and with this you'll notice some improvment on 3D too, but don't expect miracles, max 1 or 2 FPS.

For overall better 3D performance, improved 3D drivers are needed.

Read speed is acceptable, but write speed is strange. Once again a problem, or just the PPC460 design?

Right now, it's a "safe" setting which preserve data coherency when DMA is involved (the L2 controller do buses snooping)
We'll do more tests to see if we can "relax" the setting a bit, or if it's better to keep it.

@shadowsun

Good to see the L1 problem solved, the RAM speed now is in line with other Flex 800 machines (before it was wrong)

You need to re run the patch every time you reset the machine.

A bit more info about the "patch": the problem was seen the first time on the new Sam460, slow L1 access speed. After a lot of research, it turned out the problem was a misconfigured register (MMUCR) which sometimes is set incorrectly.

Then we looked at the 440, to see if the problem was there as well, but we never incountered the problem in our lab, until this test results came out from other users, which showed than some 440 may show the problem as well.

A new 440 kernel (currently in betat testing) set the register correctly, but I don't know when it will be released.

In the meantime, my intention, is to put a little executable on OS4Depot next days.

PS. you can contact me here: mtretene _at_ acube-systems.com

Thanks for the test, indeed it seems there is a misconfiguration on your machine.
Could you please try running the little executable from here:

http://www.sam4x0.com/files/mmucr.lha

and try Crisot test again?
