Thank you for the tip but I don't use directly QEMU, I try to use fs-uae with QEMU-PPC.so to use Classic-OS4 under Unbuntu-PPC.

ah..understand but the fs-uae is not for ppc but only for x86
the ppc version is only 68k without the qmu parts :(
if you will able to run it with some tricks le me know because will be a great news .

"fs-uae is not for ppc but only for x86"

Sure ?

http://forum.hyperion-entertainment.biz/viewtopic.php?f=35&t=2668

But better to stop the off-topic to don't pollute the Xeno74 thread

@xeno74

umm... do you have did the "git clone of https://github.com/FrodeSolheim/qemu-uae"
it is need for ppc emulation but need the last fs-uae from git too". you need to clone both in the same directory example /uae/qemu-uae /uae/fs-uae and after start compiling.
On my wheezy last fsuae dont make :(
look like there is a problem in the bash script

Quote:
cd . && -r -Z store /home/luigi/Scaricati/fs-uae/fs-uae.dat share
/bin/bash: -r: command not found



before was working was pretty fast in 68k only but nothing comparable with jit from Almos.

As you can see here, I have compiled the latest qemu-uae & fs-uae dev20 but when used to start OS4 it crashs.

For me the problem is with last git version of FS-uae the "archive source" compile ok without problem but as Frode say the two git is needed for the qemu ppc . The git qemu look like compile without errors make the qemu-ppc.so but the problem that i encounterd is with the FS-uae main.

Guillaume do you have the kvm enabled on X1000 ? can be this the problem there.

@tlosm

The "PR" KVM kernel module isn't loaded automatically. If you want to use "PR" KVM on your AMIGA one X1000, then you'll have to load the "PR" KVM kernel module first.

sudo modprobe kvm-pr

"Guillaume do you have the kvm enabled on X1000 ? can be this the problem there."

Not better with the modprobe command of Xeno74

@xeno74

It works but I have a new behavior with this RC.

At boot, I have a message "eth0: Could not attach to phy" that I didn't see before and when the Ubuntu desktop is displayed it is looking for network.
After a while, I have a notification "Wire network is unplugged" but the network works well (I'm posting from RC6).

I made 3 boots and to be sure I retested with 3.17 and neither kernel message nor "network unplugged" notification.
During my previous RC test (the RC4), it worked well but I don't save it (I overwrite the 3.18 kernel during each RC test)

I use the RTL8139 PCI card.

Thank you ;)

@zzd10h

Thank you for testing the RC6 and thank you for your report because of the network behavior. Could you connect your network to the PASEMI (Vitesse VSC8221) network chip, please? I'd like to know if it works with the RC6 on your A1-X1000.

Thanks in advance,

Christian

I made more test.
eth0 = pasemi
eth1 = rtl8139

1) booting with pasemi plugged.
-message "eth0 could not attach to phy"
-no "search for wifi" icon
-no "wire network unconnected"
-network OK
----> except the new message "eth0 could not attach to phy", all is like before

2) booting with rtl8139 plugged
-message "eth0 could not attach to phy"
-"search for wifi" icon present at upper rigth corner (see capture.png)
-after a while, a "network unplugged" notification occurs (see capture)
-network OK

I think I have found the problem today.

Download: vmlinux-3.18.0-rc6-2-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

Could you test it again, please?

Thanks a lot for your help.

Cheers

Christian

Done and it works well. No more eth0 message during boot and no more Wifi research.

By curiosity, what was the problem ?

Thank you

@zzd10h

I have figured out, that the new address configuration for the device-tree is responsible for the behavior of the PASEMI network chip. The kernel developers changed the source code for the address configuration last week because it was a historical hack that treated missing ranges properties as the equivalent of an empty one. But our A1-X1000 needs this hack. I have reverted the changes today and now, the PASEMI network chip works without this strange behavior.
