User Zone / Is it okay to hard shutdown with disconnecting power source at Petitboot screen?

« on: February 02, 2020, 10:24:28 am »

I usually drop into skiroot by selecting Exit to shell option in Pettitboot menu then shutdown with `halt`command. Wondering if hard shutdown by disconnecting power source is just as good?

General Discussion / ASUS Hyper M.2 PCI-e X16 V2 Expansion Card and Support for RAID on CPU

« on: February 02, 2020, 08:15:56 am »

I am doing homework for a PCI-e 4.0 X16 card to host many M.2 NVMe SSD in RAID config for my Blackbird /w POWER9 V2 8-core box.

I learn that the ASUS Hyper M.2 PCI-e X16 V2 Expansion Card is one popular choice amongst AMD Ryzen Threadripper platform.

I would like to ask if the Blackbird offers the similar RAID on CPU support? Is there any pro-sumer/enterprise product that offer PCIe 4.0 NVMe SSDs RAID?

Applications and Porting / [DEV] asdf support for ppc64le status

« on: January 27, 2020, 05:04:24 pm »

Hi all

I am in the process to migrate to the Blackbird box I've just built. There are plenty of dev softwares that aren't running yet on Linux ppc64le. Slowly I think we will get there...

Anyway, if you are using `asdf`, I would like to report that following language installed successfully:

* ruby
* erlang
* elixir
* nodejs

Other languages that are used to have issues:

* golang (now supported after the merger of ppc64le support)
* rust (now support after the merger of ppc64le support)

So far so good
