Yes, I used the correct port. I also create a new user but I'm not sure if freebsd@minicloud.parqtec.unicamp.br is the correct host I should connect to!

Yes, I used the correct port. I also create a new user but I'm not sure if freebsd@minicloud.parqtec.unicamp.br is the correct host I should connect to!

I do not remember exactly whar was set as user for the FreeBSD image, but ssh user@minicloud.parqtec.unicamp.br -p 40xxxshould work.

@jr-santos98 can you help here ^

Hi, I just received an email saying my account (just created 2 weeks ago) is ending. I have not even had time to use it yet. I need it for a 2 year research project for the UK NHS. Can someone from the management team please setup my account NOT to expire for 2 years please?

@jr-santos98 please, add @DavidARivkin in the long term users list ^

@mamonet_gitlab This FreeBSD image is not closed, it needs to be configured. For this, they created these tutorials: https://wiki.freebsd.org/powerpc/QEMU
After you follow it, you will be able to connect via ssh as you normally do with the other images on Minicloud.

@jr-santos98
@rpsene Done.

@rpsene
@bencz we are going to renew the certificate.

@bencz

@rpsene
@/all certificates are now fixed.

Does anyone know of a code generation tool for PPC64, like xbyak https://github.com/herumi/xbyak or vxil https://git.linaro.org/arm/vixl.git/about/ ?
Rafael Sene
@rpsene
@JoelLinn I will poke some folks inernally. I’m not sure whether or not there is somethign similar. In the past I used to work on the Power SDK, where we implemed a Migration Advisor tool which aimed to help moving from x86_64 to ppc64le by suggesting source code fixes and improvements.

too bad that there is no support for qemu-system-ppc64 support, on Windows 10 hosts

Иван Сердюк
@oceanfish81_twitter

I'm using that Debian image from @JoelLinn ..., just making a stress test...

@bencz , are you running under Qemu (on Windows 10, as I might suspect)?

Rafael Sene
@rpsene
@oceanfish81_twitter is there Qemu for Windows?
there is, learned something new today.
Иван Сердюк
@oceanfish81_twitter
Anyone here interested to contribute into the support of POWER ABI, for https://go.googlesource.com/gollvm/ project ?
Rafael Sene
@rpsene
N
@oceanfish81_twitter let me check if we have someone looking at it, give me some days to reply.
I know we have folks working on LLVM for Power.
Иван Сердюк
@oceanfish81_twitter

@oceanfish81_twitter is there Qemu for Windows?

Yes, I am able to run the "cloud" image (from @JoelLinn ) - I use https://qemu.weilnetz.de/w64/2020/qemu-w64-setup-20201124.exe

Иван Сердюк
@oceanfish81_twitter
I can confirm that it runs 32bit ppc and ppc64 machines - but for some reasons not allowing to boot pseries-2.8 and above (I had to boot 2.7). Also relic 32bit power distros boot "Mac99 " virtual machine.
It is interesting that the situation is that same on Linux hosts, to be fully awenest
I do not know the cause - but I could try to check something specific (like tracing, exporting logs, writing reports). If you could instruct me about what should I do
...I am dealing with gollvm issues, for some time - so yes, I would much appreciate if someone could join existing committers
POWER is one of few architectures that has predictive future evolution, in sense of both system-on-chip and system-on-board solutions - so supporting Go on POWER would be of help
Rafael Sene
@rpsene
@oceanfish81_twitter GO is supported on Power. I forwared your ask about gollvm to the Toolchain management at IBM, stay tunned for a reply on this.

Probably you are talking about Bluemix cloud.
Thanks, I could be reached via emailing: ivan.serdyuk.1988@gmail.com

@cherrymui and @thanm are dealing with gollvm, from Google's side (x86_64 and Aarch64 are currently supported - and I am still interested to fight for i686 support)

@oceanfish81_twitter
@JoelLinn , why binfmt is required?
Иван Сердюк
@oceanfish81_twitter
@JoelLinn , how to reconfigure systemd services' timeouts (depending on a predictive performance of the hardware/server or Qemu) ?
Joel Linn
@JoelLinn
Binfmt for what? Building the ppc64 BE image? Thats if you dont run on ppc64, it allows to chroot into the image with qemu-user-static.

Well, I don't imagine why installing pip assumes chroot'ing - but there was a warning, so that is why I asked

Alexandre Bencz
@bencz
@oceanfish81_twitter Yes, I use on Windows 10
Just change the ISO image file and the qcow2 file on qemu parameters
Иван Сердюк
@oceanfish81_twitter
Where could I check the matrix of emulated/supported POWER instructions, for Qemu?
Alexandre Bencz
@bencz
@oceanfish81_twitter As far as I know, it supports all instructions ... even Power8 ... and does not support Amazon instructions as they are not documented by IBM

And what about https://www.ibm.com/support/knowledgecenter/POWER6/iphb2/iphb2hypervisor.htm ?
AltiVec?

@sebastianbiallas , would you explain about Altivec ?
Иван Сердюк
@oceanfish81_twitter

@bencz , do you know anything about

... what is the status of https://wiki.qemu.org/Features/tcg-multithread , for supporting ppc64 guests, under Qemu ?
