Hi,

wanted to let people know I'm trying to sort out a few issues, if anyone can help or knows anything that might help, please help!!

Mesa, https://github.com/threader/mesa-ppc-debian
Mesa has been dead in the water since the transition from UMS (User Mode Setting) to KMS (Kernel Mode setting) for PPC Linux, and mostly floating upside-down in a moist pit of sewage prior to that change. I finally managed to google my way to something that sorta works. The endian patches by Michel Dànzer - http://lists.freedesktop.org/archives/mesa-dev/2013-December/050218.html

I'm aware of the Mesa project for X1000 , however r300 was still broken there last time i tried. I did not try the Xorg.conf or use radeon.agpmode= -1 ( Forced treat as PCI) which i need do now.... Anyway, it results in 500~ 750 fps glxgears. Half to 1/3 the speed of which it ran on Debian Sneeze( in 2012/13), once configured...

Mac-On-Linux, https://github.com/threader/Mac-On-Linux
Not seen an update since 2011, and it's showing some age, it and i'm presented with a nice, black screen upon loading the mol video driver which it does entering OSX-. However, MOL is the only way to actually install OSX 10.x on linux, Qemu cannot do that, it can boot osx after you've installed and configure it correctly, but not install....

Thanks a lot, some things i were not aware of here.

So with this i can drop the big endian fix and colour ?

3D acceleration doesn't work with your Radeon chip. The problem is, the r300_dri.so that is shipped with the unofficial Mesa version is the Gallium driver. This only works with DRI2. Unfortunately it seems your ATi Radeon chip isn't compatible with DRI2, so all of the 3d rendering is done via softpipe. I compiled Mesa 7.11.2 classic (DRI 1) for old graphics cards.

Download: http://www.file-upload.net/download-10830613/Mesa-7.11_Debian7.7_classic_dri.tar.gz.html

I compiled it for Debian 7.7. I hope it works for you.

Installation instructions:

Copy the unpacked Mesa directory to /usr/local:

Quote:

cp -R Mesa7.11.2-without-gallium /usr/local

mv /usr/lib/powerpc-linux-gnu/dri/r300_dri.so /usr/lib/powerpc-linux-gnu/dri/r300_dri.so.bak

Quote:

cp /usr/local/Mesa7.11.2-without-gallium/lib/dri/r300_dri.so /usr/lib/powerpc-linux-gnu/dri

There is a new version of Mac-on-Linux available. It works with KVM so you need a Linux kernel with KVM support.

Download: mol-kvm_0.9.73.0-ubuntu_powerpc.deb



OS X works with QEMU/KVM too. But it isn't as fast as Mac-on-Linux/KVM.

Hi, thank you for for the detailed reply, however degrading isn't an option, i quickly run past packages that require both the newer mesa and X11. It's now doing 800 fps with some things in the xorg.conf left out, and thats mesa 10.6.3. Also to use acceleration the way you described wouldn't you need to have an older kernel which supports UMS?

Btw, using MOL and Qemu, anyone have problems with certain ram values? had unexplained problems allocating 768 megs to the VM, popped it down to 512 and 256 and alll issues wee gone, bump it up to the 300's and into problems it runs.


Btw, i spotted i had converted the semaphore in MOL to a mutex at some point... Rolling back that change apparently did nothing... So why i had done that i donno, any changes made to your Mol?

No, I haven't. My virtual OS X machines (Tiger+Panther) have 2GB ram.

No, I didn't make any changes to MoL. It's a new MoL version with KVM support.

Ok, i've got the desktop running with compositor now, very snappy and fast, though as you can see there are bugs, glitched as i was about to take the screenshot too.. for some reason to xscreensaver lock screen...

@mike

is this new version of MOL working on AmigaOne or X-1000 ? AFAIR none of the linux distro would enable DRI on AmigaOne machines (because of missing cache coherency and another thing I can not remember).

@lionstorm

I think he mentions it is on the X-1000. I too would really like to have MOL working on my AmigaOne though!

The kernel has an AmigaOne option still.

That version of mol ran a few years ago, though i've not had any success with kernel 4.0.x.... and now the mol video driver seems to crash the machine, some debugging is needed, , but as far as i know it runs with kernel 3.x - though i dont have time to recompile a 3.x kernel and test.. as a full debian kernel build takes years. qemu works , and is up to date,

For the AMIGA one X1000 you need the kernel 3.17 or higher to use MoL with the KVM "PR" kernel module.

Edit: MoL/KVM works very well on the AMIGA one X1000. I can use Mac OS X Tiger and Panther.

Ok, good stuff, i compiled linux 4.1.x yesterday, still fast and good, crashes are a bit less, it still can crash when under heavy load (cpu and gpu), but not as frequent, i have a few more days to figure stuff out before i leave everything again for now.

I went to dig out what i thought would be the second non applied patch to mesa for big endian, only to discover this was appleid,, does the x1000 ubuntu mesa have any other patches im not aware of for BE?
Btw, Is KVM for the G5 still removed from main?

Mesa is a big topic. Please look in the following thread: forum.hyperion-entertainment.biz.

Yes, KVM for the G5 was removed.

Actually this MOL version should also run on the original AmigaOne given that some of the kernels I released lately on the sf.net/projects/amigaone-linux/files/debian package repository also support KVM (with a bad hack though). I tried MoL for KVM on my A1SE some months ago and it was very sluggish. On the other side I could do a full Debian Linux installation within QEmu under KVM and that was running just fine (probably because of the text-only output).

And you're right: DRI is more or less a hopeless case on the original AmigaOne. I only had DRI1 working on the A1SE with all other DMA-capable devices operating in PIO mode only.

That's why some of my new kernels support KVM. On the other side I also started to compile SMP kernel (for multi processor machines) recently. That my sound weird for the original AmigaOne machines, but these SMP kernel run a lot more stable on some machines (especially with G4 CPUs), but unfortunately do not support KVM on 6xx/74xx CPUs yet.

Great! I'll check that out. I have my AmigaOne Set up to quad boot into Etch, Lenny, Squeeze or OS4.1 FE depending on the boot menu selection you choose.

What do you recommend for me to be able to get MOL working? I finally purchased an official Apple OSX 10.4 Tiger....

Thanks!

Oops...wrong again.....My AmigaOne can boot into
1) Amiga OS4.1 FE
2) Lenny Mint8 kernel 2.6.31-1
3) Lenny kernel 2.6.18
4) Lenny MOL-cache kernel 2.6.18 (MOL never worked though!)
5) Squeeze Mint 9.2 kernel 3.1
6) Wheezy kernel 3.1 (EXT4)


So, I am typing this from my Wheezy Debian boot....

Again, which kernel / Debian version is recommended for MOL?

I see you have this one ... linux-image-3.2.0-4-book3s-amigaone+ does that one support Wheezy and the MOL.deb linked in the previous post?

Scott

It looks like you have three different boot images for AmigaOne on sourceForge as follows:

boot.img.amigaone-2.6.32-5-book3s-amigaone
boot.img.amigaone-3.2.0-0.bpo.4-book3s-amigaone+
boot.img.amigaone-3.10.0-0.bpo.2-book3s-amigaone+

but the readme info only talks about the 2.6.32 image which does not show support for kvm. I assume one or both of the other two kernel images have your "bad hack" to support KVM then?

So, if I install one of these kernels in my wheezy partition and set up the a1boot.conf file to add it as a boot entry for my microA1, boot into it, will I then be able to use the MOL deb file provided above with it to get MOL working?

Thanks,

Scott

I recommend at least Debian Wheezy, as this is the version for which I compiled the kernels till now.

Quote:

IIRC I downloaded a complete OS X upgrade package the last time I installed OS X (in case you have a version below 10.4.11). Otherwise you will get old until all system updates have been downloaded and installed one after another.

Even better!

Uhhh, I can't remember.

It comes with KVM support enabled, but I don't know if it comes with the hack to actually make KVM work on the AmigaOne. Maybe you better use the v3.16.7-ckt9-3eb8u1 kernel that I compiled for Debian Jessie (I yet have to do a proper backport version for Debian Wheezy).

Forget about these boot images.

The new kernel packages are designed to be installed on a system equipped with the new amigaos4-slb bootloader scripts. So a good start would be to convert your Debian Wheezy installation to these bootloader scripts, as they allow to install kernel packages with a one-liner resp. a simple click in the package manager!
Thus the right way to install such a kernel package is to add the Debian repository on sf.net/projects/amigaone-linux/files/debian to your installation's sources.list file and then install the kernel package using the package manager. Please read the readme.txt in the "Files" section on sf.net/projects/amigaone-linux for how to do this. You would have to use "jessie" instead of "wheezy" as distribution to get the v3.16.7... kernel version.

However this reminds me that I have to upload the amigaos4-slb Debian package (which contains the bootloader scripts) to the Debian repository first, so that people can actually install it on their systems. I guess I also need to write a conversion guide for existing installations, right?

Honestly I cannot guarantee that it works. As I mentioned before: I tried it on my A1SE some months ago, but wasn't satisfied with its performance and stability.
Also I don't know about the dependencies of this MoL package. Thus I would first try to install the MoL package just to see, if it installs cleanly. It that works you can go on with the bootloader scripts and kernel package installation.

BTW: Do you have a uA1 with FX or GX CPU?

I set up the sources.list and keyring to add your sf.net/projects/amigaone-linux stuff, and that went okay. I recall seeing only one kernel version available under the aptitude kernel section, and I didn't know what to do from there.
On my wheezy partition, if I just do an apt-get upgrade it will upgrade me to jessie? Will my current kernel ... I think it is 3.1 or 3.2, work with jessie? I don't want to get into a situation where I cannot boot into my wheezy partition if i try to update to jessie......

IIRC the script files Hypex was working on which you had given him to autoscript the boot updates didn't work...it had some bugs. The first one I recall was that the boot folder is actually under /boot/boot and NOT under /boot for A1 machines..... the slb goes to /boot/boot/a1boot.conf to get the config parameters, and the script Hypex had went to /boot and didn't find anything, and then updated everything in the wrong place.
Not sure if your new script looks under /boot/boot like it is set up for A1s or just /boot which will not work.
