Another very important feature related to sam460ex should be 2gb ram support

@tlosm

The links you post are only handled using GIT.

You could insert a link to the GitHub interface instead, for example: https://github.com/dgibson/qemu/releases/tag/ppc-for-4.0-20190226

It's not only accessible to anyone with a browser but also comes with a changelog :)

hi @Leo

i write the git link because i have it from the qemu developers mailing list.
just make copy & past for the git link and the hilight upgrades.

Git is available for all main Os (Linux, MacOsX ppc,x86 and windows) plus for the homebrew systems.

Chrome won't open git:// links: although I have git cli tool installed, clicking on your links just prints an error or nothing (depending on the OS/browser).

That's without mentioning the fact that your links are wrongly parsed by Amigaworld which crops the link in the middle.

But nevermind: that was just a stupid suggestion to make your links accessible to everyone...

Here's a final pull request before the 4.0 soft freeze. Changes
include:
* A Great Renaming to use camel case properly in spapr code
* Optimization of some vector instructions
* Support for POWER9 cpus in the powernv machine
* Fixes a regression from the last pull request in handling VSX
instructions with mixed operands from the FPR and VMX parts of the
register array
* Optimization hack to avoid scanning all the (empty) entries on a
new IOMMU window
* Add FSL I2C controller model for E500
* Support for KVM acceleration of the H_PAGE_INIT hypercall on spapr
* Update u-boot image for E500
* Enable Specre/Meltdown mitigations by default on the new machine type
* Enable large decrementer support for POWER9

Plus a number of assorted bugfixes and cleanups.

Fantastic!
Did you had the chance to try it out on your Threadripper?

Did you noticed any performance improvements while using AmigaOS 4.1, especially for what it concerns floating point operations?
Is it making an emulated Sam460ex more usable at all?

@ALL

a message from Zoltan for all

Hello,
Hardfloat is still disabled for PPC in QEMU 4.0 because no one has
implemented the necessary fixes for it yet. Volunteers are welcome. See:
https://lists.gnu.org/archive/html/qemu-devel/2018-11/msg04974.html

Some AltiVec optimisation are in QEMU 4.0 but those are not useful for
AmigaOS which only runs on sam460ex currently which does not have AltiVec.
It may be useful for some benchmarks under MorphOS on mac99 using
AltiVec/VMX but maybe only the mplayer one as lame_vmx is still floating
point bounded. Other than that there were some other optimisations but
their effect is probably minor.

QEMU 4.0 will have the fixes listed on my qemu/amiga page in the News
section (an IDE fix, the lwsync patch and 2GB memory fix) and the
outstanding issue with some programs crashing (mentioned in known problems
section) that I don't know how to fix because it was only seen with large
programs or OS itself that I can't debug. I don't know about a simple
reproducer that could be easily debugged.

Regards,
BALATON Zoltan

Looking forward to seeing SAM460 emulation running well on my Quad G5.

BTW - Could you recommend a good Linux distro?

Me too use mate 16.04 ppc 32/64bit on G5 quad.

One alternative is Fienix by Casey Cullen, a really ggod boy.
I suggest you to try this as first step, because is more updated and has a lot of impoerant tools like arctix fox browser and others.

Look also here:
