hardware OS4   hardware OS4 : Updated 2.6.8 AmigaOne Linux kernel.
   posted by Geri on 7-Dec-2006 9:41:42 (3095 reads)
An updated 2.6.8 AmigaOne Linux kernel is available at amigaone-linux.sourceforge.net together with a patch for the 2.6.8 Debian sarge kernel source package.


Changes in this release:

- Highmem support is working:
You can remove the memory limit in U-boot now.
- EHCI support removed:
The EHCI driver doesn't work on the AmigaOne due to the non coherent cache DMA workaround and I was to lazy to backport a workaround which was contributed by Marcus Comstedt. Many thanks to him for this patch!
- DRI graphics drivers removed:
These drivers were removed, thus you can enable the glx extension of the X server again.
- ISA bridge tweaks:
Recently I experienced problems with USB on my A1, too. Therefore I tried to weak the settings of the VIA southbridge (to match the settings done by OS4). This seems to help a little bit, but after some time the system locks up again. I'm still not sure what the real problem is, but I guess it's either the unfixed CPU bug or an interrupt problem.
Unfortunately I wasn't able to get a response from the (responsible) OS4 developer(s), so I can't really do anything about this. (I remember sg2 writing about a software problem with the i8259 PIC. I would be grateful, if he could enlighten me!)

An updated 2.6.16.x kernel package will follow around the 16th of December (hopefully). It will also include a working EHCI and PC speaker driver.

This is realy nice. Would the USB mass storage module be included with either 2.6.8 or 2.6.16.x? This is much needed and missing from the 2.6.16.27 at the moment AFAIK.

Thanks,
Firbodi

USB mass storage support was included since the first kernel release. I only removed EHCI host controller support, because it crashes with the non cache coherent DMA workaround.

Oh! Thanks! I figured my mass storage set up was not complete. I got it working now.

Thank you for the nice update. Linux is working better than ever on my MicroA1.

I hope you'll support the Sam board as well
Thanks.

Hi,

Can you tell me what I should install/do to get the USB mass storage working?

Thank you.

Install the hal-device-manager and add yourself to the plugdev group. That should do the trick.

Generally, yes. But this depends on whether I can afford the hardware or not (I'm not sure, if I'll buy another AmigaOS4 hardware, as I already have an A1). It would also only make sense, if there is still something to work on. I guess the AMCC 440EP platform is well supported by Linux!?

That sounds like a hardware defect or what do you mean with "don't even receive power when inserted"!?

You have to add your user id to the plugdev group in /etc/groups.

Hi,

You know when we plug something in the USB port like my 512Megs memory stick the LED flick a few moment. The Hardware is OK because it's working fine in OS4.

I alway log as ROOT so I'm not sure it's require to add my user id to the plugdev group in /etc/groups. I'll check that tonight.

Bye!
