I've searched some very old HDs but haven't found anything interesting so far.

could be a compilation problem, as I used a different gcc, will try using another one.

@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

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

@Hans Quote: 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.

@Hans Quote: 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.

@Hans Quote: 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.

@geennaam FROM the 460ex UM: Quote:
The DDR controller utilizes 34-bits of the 36-bit PLB address.
The most significant 2 bits of the 36-bit PLB address (bits 28 and 29 of the upper 32 bit address) allow the 34-bit address to have an alias on the low latency and high bandwidth PLB slave segments.
Accesses with the upper two bits set to 0b00 are made over the low latency (LL) slave interface and accesses with the upper two bits set to 0b10 are made over the high bandwidth (HB) slave interface.
The internal SATA controller under AOS4.1 works in PIO mode because we didn't find any developer willing to write a DMA driver for it (it requires gather/scatter lists) Under Linux it works in DMA mode.

@geennaam AFAIK, under AOS4.1 DDR and PCIE are located on the LL PLB segment (and mirrored on the HB) since it uses the settings from U-Boot:
#if defined(CONFIG_440SP) || defined(CONFIG_440SPE) || \
defined(CONFIG_460EX) || defined(CONFIG_460GT) || \
defined(CONFIG_460SX)
/*
* Enable high bandwidth access
* This is currently not used, but with this setup
* it is possible to use it later on in e.g. the Linux
* EMAC driver for performance gain.
*/
mtdcr(SDRAM_PLBADDULL, 0x00000000); /* MQ0_BAUL */
mtdcr(SDRAM_PLBADDUHB, 0x00000008); /* MQ0_BAUH */

@amiganuts
you can type it from the serial terminal, just boot without any media attached (sata/usb etc) and at the end of the hw init sequence you will have the uboot prompt on your serial terminal.
