I've found only some snippets of code from the AmigaOneG3SE u-boot source code, maybe the following code may help:

In our tests, the SIL 3112 is unreliable when used with a Sam460 board, the exact cause is unkwown.

There is a Pericom 8150B PCI Bridge on Sam440ep mini-itx and flex boards, maybe it's testing it ?

Try the Sam440ep_setup utility from OS4Depot:

http://os4depot.net/share/utility/shell/sam440ep_setup.lha

if it help with your dragging open drawer windows slowness, which is in part due the HD 5450 used which has a PCI-PCIe bridge onboard.

@balaton

the sm502 driver set chip endianess to big endian writing 0 into register 0x005c.
This seems not to work in PCI mode (the chip remain in little endian mode), but maybe on the Pegasos emulation there is some side effect ?

The Sii3112 card is likely to show instability on Sam460 boards, replace it with a 3512 or 3114.

the driver assumed to always run on a 460, and used CPU time base 64-bit register for time delay

- bigger screen resolutions support
- corrected the problem with the boot delay on Peg2 emulation
- better read/write and blitting performance on real hardware
- some bug fixings

if you're using the SM502 driver, you can try the upcoming 53.12 available on the beta-ml later today

While the ATOMBIOS ASICInit function should theoretically initialize the card from zero, we found that cards typically wouldn't work properly unless the motherboard's firmware did the lowlevel initialization first

I've ported ATOMBIOS into Sam460 U-boot version, and ASICInit indeed seems to initialize correctly the card but ATM I cannot get any videomode working. Do I need to call the classic x86 BIOS emulation before calling ASICInit, or something else need to be done to have a basic 640x480 screen mode ?

There is a good chance that it will be available on OS4Depot and/or on ACube web site, after finishing some other improvements.

I wasn't aware of that. So the SM502's blitter won't copy or use the alpha channel? That's a weird thing to do.

The chip uses a different 16-bit layer for alpha. Maybe these is a way to implemet some sort of alpha support compatible with graphic.library...

Anyway, I've a new driver version which, on real hardware (not emulated) greatly improve CPU and DMA trasfer speed.

Following up on this, the problem is that the emulated hardware is an SM501, which is limited to 16-bit colour output. We're lucky that the SM502 driver can handle the SM501, or it wouldn't work at all. We could get 32-bit if the SM502 were emulated instead.

The SM502 driver under AmigaOS4.1 is limited to 16-bit since its 32-bit mode AFAIK isn't support by graphics.library.
The chip uses 4 bytes, 3 bytes for RGB, and the last byte isn't used at all.
From my tests, AOS4.1 support 24-bit modes (3 bytes) or 32-bit modes (4 bytes with alpha) but not 32-bit modes without alpha.
The result is that trasparency doesn't work.

Re: NVMe device driver

@geennaam

Testing a Lexar Professional NM700 M.2 2280 PCIe Gen3x4 NVMe 256GB SSD on a Sam460le, with a PCIe 1x adapter, into the PCIe 1x slot.

U-Boot and AOS4.1 recognize the device, but on the AOS4.1 side I cannot format nor partition it.

Tried with different FS and different partition size, without results.

When I put the same NVMe and adapter into a PC, it works correctly.
After formatting it (FAT32 or NTFS for example) and put back in the Sam460, the icon device is showed on WB, but cannot copy any file, got the following error on the serial:

[NVMe] Create CQ Failed

If you need addition info let me know.
