Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:

Description

Dashing job to subscribe to MQTT messages.

MQTT is a lightweight publish/subscribe messaging transport. This job allows Dashing to subscribe to these messages and send them as events. There is no associated widget as the data can take any form - commonly numbers, but not necessarily. The script as laid out below sends events with value, current (the same contents) and last values so can be plugged directly into the Numbers or Meter widgets using the data-id in the dashboard file. The send_event could easily be modified if required.

Set up

Add to Gemfile:

LIRC patch instruction/how-to for USB Infrared Toy from Dangerous Prototypes

This is a instruction to patch the usb infrared toy driver into lirc sources. Most of the work is done by Peter Kooiman

Requirements

Debian based OS (only tested on rapbian)
root privileges
USB Infrared Toy

Raspberry pi dashboard

This is what we did to setup a few dashboards at platanus

You'll need

Raspberry Pi
Dashing Service
Wifi stick (optional)
