• Legacy pin interrupts

— For devices that use legacy methods for interrupt routing (such as either through direct wiring to the I/OxAPIC input pins, or through INTx messages), the I/OxAPIC hardware generates the interrupt-request transaction. To identify the source of interrupt requests generated by I/OxAPICs, the interrupt-remapping hardware requires each I/OxAPIC in the platform (enumerated through the ACPI Multiple APIC Descriptor Tables (MADT)) to include a unique 16-bit source-id in its requests. BIOS reports the source-id for these I/OxAPICs via ACPI

My NVIDIA GTX 980 Ti being idle eats 53 W (out of 250 W max). Here's how to put to to a power saving mode at 30 W consumption and keep it prepared to run at higher performance automatically when there's a computation running.

ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

Go to your computers/phones settings
Ensure Bluetooth is turned on
