Huge congratulations on reaching this milestone! Icaros plays such a vital role in making AROS a truly useable system and I don't think its role in advancing AROS can be overstated. Many, many congratulations.

Cheers,
Nigel.

P.S. It's really good to have summarised the 10-year history of Icaros, and along with that the history of AROS development in this time.

Yes, exactly - and when set the machine would not boot and I had to reset the bios via the jumper. Believe me, I tried every option and there was no way to make native USB work; in the end I bought a PCI USB 2 card so I actually had a functional USB. My original point was that USB (and in addition to that point SATA) are so fundamental to getting a machine working. If you look through these posts you see more and more modern machines failing on the SATA and as mentioned my experience with a couple of recent machines is that USB does not work at all or if at all in a flakey manner.

Imagine someone new tries AROS on their < 4 year old hardware and their live disk fails due to SATA and their USB boot also fails due to USB. That's it - they most likely will not persevere or seek out old hardware to try to get things working (even if said old hardware is merely up in the loft), the disk will go in the bin and they'll move on. Now, don't get me wrong - I've never presumed to tell the devs what they should be doing; it's their time and energy they are expending and their right to do what interests them, but as Steve opened a debate as to what drivers might benefit from some love I put my penny's worth in. However, I must admit to being worried that once the 'iMica generation' of hardware has bit the digital dust it may be damn hard to find systems, particularly laptops and netbooks, that will allow even the basic functionality of AROS.

Cheers,
Nigel.

Most boards you can change USB3 into USB2 via EHCI/OHCI/XHCI BIOS settings so USB3 is NICE but not necessary for AROS

Certainly that works on my X99 board

I really think our biggest limitation is the lack of modern VGA drivers :(


It's been a few months since I last played with the Gigabyte board due to real-life events, but as I remember trying to set the controller to 'legacy' USB stopped AROS from booting at all (boot stalled during kernel setup).

Cheers,
Nigel.

USB1.1 and USB2.0 should work so I don't understand the statement that "its not for USB 3 devices, it's just for USB full stop."

USB3 devices should work with USB2 host controllers (slower ofcourse)

"Basically AROS has no driver for modern xhci controllers.
" I know that and that is the reason why I started the work for it years ago. It was obvious back then that older USB host controllers will become obsolete.

The state of the AROS XHCI driver as far is that AROS is able to enumerate the XHCI controllers, Trident will list them and Poseidon will know that they are SuperSpeed and will bind hubss.class to them (hubss.class is just a copy paste from hub.class at this moment)

XHCI driver knows its port count and is able to detect device insertion and soon after crash. Ring buffers need some love (implement correctly) Memory allocations are bad in XHCI driver (lots of different alignment needs) I could have just allocated a lot more memory than needed and align the start of allocated memory but that would be wastefull.

Also the XHCI driver higher level code is coded based on the USB2 drivers. Those are difficult to understand because of the massive switch statement that they house. So as to understand the driver mechanics better I implemented a hosted version of usb driver. It is much easier to understand as it is abstracted and has no huge switch statement.

I no longer have any dedicated native AROS machine but if I had I would take the higher level code as a reference from VUSBHC driver and implement that in XHCI driver.


On the Gigabyte board nothing works - not USB 1, 2 or 3. Neil has the same board and confirms AROS simply cannot use the onboard USB at all. On the Acer, to be fair, a memory stick can be opened - but when accessing its contents the machine quickly crashes so that's not too useable either.

Cheers,
Nigel.

Stop using motherboards with VIA-chipset. Or it might be that the motherboard (BIOS) doesn't list the USB PCI device in correct order as stated on USB specifications. Those are really ancient motherboards.


These are not VIA - one is Gigabyte, the other an Acer laptop, both less than a year old and bought new. Basically AROS has no driver for modern xhci controllers.

Nigel.

I've found formatting USB sticks to be very hit and miss. It's been a while since I did that, but here's some notes I made for myself the last time I managed to do it successfully:

(1) Wipe partions off disk with Linux partition editor; put on MSDOS 'disk label' but do not add partion.
(2) Do Install AROS with 'use free space'; DO NOT remove USB before 'Use existing AROS partitions' (with format).
(3) After install, reboot machine.
(4) May loose partition format but will keep partition structure; if so, redo 'Use existing AROS partitions' (with format).

I just used a Linux live DVD for part (1).

It does rather sound like your AROS does not like your machine's SATA chipeset. I've recently bought a machine for which the SATA chipset was not recognised at all; I had to buy a SATA/IDE PCIe card to allow hard drive access. Does you machine have any free PCI or PCIe slots?

Cheers,
Nigel.

I think 10-mile high statues should be built to honour the devs and distro builders. In solid gold, of course

On a more practical note, I feel the biggest current driver issues is USB 3 - the two machines we've bought in the last couple of years have this and AROS simply cannot make use of their USB.

Cheers,
Nigel.

That's a useful tip to remember (who'd have though an incorrectly configured AHI could bork Janus?) Thanks for letting us know.

Cheers,
Nigel.

The 68k configuration from the AmigaForever distribution may need some tweaking to work with Janus. Have you tried starting in windows mode rather than full screen to see if it can at least get the 68k system booted? Another thing to try is to start up Janus without any drives selected to check the emulation shows the 'insert boot disk' animation - that would confirm Janus is working.

Cheers,
Nigel.
