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

ppc64.bat

Just change the ISO image file and the qcow2 file on qemu parameters

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

@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

qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-cfpc=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-sbbc=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ibs=workaround
qemu-system-ppc64: warning: TCG doesn't support requested feature, cap-ccf-assist=on
?

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

Иван Сердюк

@oceanfish81_twitter

@agraf , any comments?

Rafael Sene

@rpsene

@ullbeking_gitlab I asked the developers of Qemu/KVM on Power to join this chat to help answerring some of the questions.

Иван Сердюк

@oceanfish81_twitter

thanks a lot, @rpsene

Daniel Henrique Barboza

@danielhb

@oceanfish81_twitter the TCG warnings you're seeing are related to KVM specific capabilities related to Spectre mitigation. The messages are annoying but are benign AFAIC. I'll check the code to be sure

About the MTTCG support for pSeries, the last status I heard about is that it works, but I haven't tested myself. If you find any problems running MTTCG let me know and/or post a bug in https://bugs.launchpad.net/qemu and the community can look into it as well

Иван Сердюк

@oceanfish81_twitter

@danielhb , thanks for clarifying. Could you explain why qemu-system-ppc64le was not ported to Windows 10 (yet) ?

Alexandre Bencz

@bencz

@oceanfish81_twitter I use qemu-ppc6el on windows 10 ...

Иван Сердюк

@oceanfish81_twitter

@oceanfish81_twitter I use qemu-ppc6el on windows 10 ...

And where did you get one?

wow it saved just now, tried a dozen times over the last hours and got a number of different errors. don't know if it was spurious or one of the options i played with

welll.. you can use the MiniCloud...

there is a ppc64BE image on it...

Debian PPC64 - BE

Rafael Sene

@rpsene

@JoelLinn let me known if you need any specific image at Minicloud.

Joel Linn

@JoelLinn

I just rebuilt the deb 11 ppc64 be image as I noticed people are actually using it and i get pinged in random github issues and wanted to test it

Иван Сердюк

@oceanfish81_twitter

@JoelLinn let me known if you need any specific image at Minicloud.

And why are those Minicloud instance are all targeting Qemu?
Why no bare metal hosting options?

I just rebuilt the deb 11 ppc64 be image as I noticed people are actually using it and i get pinged in random github issues and wanted to test it

Too bad that there is no Qemu emulation of POWER variation, which allows virt. capabilities. Otherwise we could test CNCF projects

Junior Santos

@jr-santos98

@jr-santos98 build a newer image with the debian cloud image scripts https://wolke.linn.io/s/AKxqLySKCDfTRYY

@JoelLinn I realized just now that it is the developing version of Debian. Because of this, in addition to adding the new image, I too renamed and added build date. The new image was named "Debian 11/sid ppc64 - BE (01/2021)"

Joel Linn

@JoelLinn

is there any way to extend the account oneself? I figured logging in now and then doesnt suffice

Rafael Sene

@rpsene

@JoelLinn nope, you need to request. @jr-santos98 can you handle this and add @JoelLinn as a long term user?

Junior Santos

@jr-santos98

@rpsene @JoelLinn Done! User added as a long term user.

Alexandre Bencz

@bencz

We are starting the development of a new backend for the ELENA language ( https://github.com/ELENA-LANG/elena-lang ) compiler, to generate ppc64le code, and all tests are being done on Unicamp's servers, so, thank you very much for the free access to the servers

Rafael Sene

@rpsene

nice!
