Applications and Porting / Intel oneAPI Deep Neural Network Library (oneDNN), basic Power ISA support.
« on: June 30, 2020, 05:59:11 am »
The patch is scheduled for the next release, v1.6:
https://github.com/oneapi-src/oneDNN/pull/767

Not a big deal, it just uses the compiler’s auto-vectorizer as it does on ARM, but it does compile cleanly and passes all tests.

Operating Systems and Porting / Re: Screen Saver disappeared
« on: April 22, 2020, 04:38:45 am »
The screenshot is not sharp enough to read the error message. After zooming in, squinting, and some help from search engines, this is what I managed to make out:

The XScreenSaver daeomon doesn’t seem to be running on display "??". Launch it now?

In cases like this it’s helpful to type the message as text too. Makes it easier for anyone that wants to help you.

This seems related to the Linux distribution you’re running. My guess is that it was triggered by some other inadvertent change, not switching from the built-in to the dedicated graphics card.

I would try searching for that error message, together with the name and version of the Linux distribution you’re using:

That might uncover some way of setting the XScreenSaver daemon (or that of any other screen saver) to run at startup.

Applications and Porting / Intel RealSense (depth cameras) SDK 2.0
« on: January 21, 2020, 11:21:50 am »
My tiny patch to make the Intel RealSense SDK 2.0 compile on POWER just got accepted.
A couple of weeks ago I got an Intel D435 depth camera, which plugs through USB 3, and it’s working perfectly now with my BlackBird.

I thought about listing it in the Wiki but being a USB device I did not see any good place to mention it and it might not be worth the trouble, as lots of USB devices just work without any special consideration.
Here it might fit better; just want to make sure there are some search results if someone is considering using those cameras with BB/Talos.

Blackbird / Re: Keyboard unresponsive at boot menu (Petitboot)

Thanks both, yes that’s exactly what’s happening. If I turn the jumper on the menu works as expected.

Blackbird / Keyboard unresponsive at boot menu (Petitboot)
« on: December 09, 2019, 04:28:07 am »
Is this a known issue?
My BB works fine otherwise, but at the boot menu the only key that seems to do anything is CTRL+ALT+DEL, so at least I can reboot.
Any other key interrupts the automatic boot, but otherwise does nothing.

I have tried different keyboards, also plugged directly instead of through a USB HUB.

I remember this working a couple of weeks ago as I was setting it up.
Is this affected by the on-board VGA disable jumper? That’s the only change I’ve made to the motherboard since then. I haven’t updated or modified the firmware (boot/BMC flash), just installed Linux in a SATA drive, which works perfectly fine and I’m using now to write this message.
