| This module implements the IR protocol for Daikin's air conditioning units. | |
| It is based on this work: | |
| <https://github.com/blafois/Daikin-IR-Reverse> | |
| And contains some additional improvements, such as: | |
| - Implementation of the low layer (IR signal protocol). | |
| The low-level IR protocol is not explained very well by blafois; | |

This document describes a process to quickly setup a Linux VM for testing or kernel development.
The VM requires no disk image, instead it boots off a directory on the host (using virtiofs). This is:
The Spanish government loves (or loved) using JavaScript in their tax forms.
This gist contains the JS blocks in the official tax form 145 PDF, version 1.0/2022. Enjoy.
The code is reproduced verbatim, except for normalizing the encoding (latin-1 to utf-8) and the newlines (CRLF to LF).
Using some iconv command + unix2dos should give you back the exact bytes in the PDF, except for one thing:
there's a stray CR without accompanying LF in object828.js:139. Yeah, idk.
virglrenderer is a library that gives emulators the necessary tools to implement a [virtio-gpu][] device, in particular one with 3D support. See capability sets below for a summary of the APIs virglrenderer can implement for the guest.
It directly implements the logic behind some 3D commands like GET_CAPSET, CTX_CREATE, CTX_SUBMIT_3D, CREATE_RESOURCE_BLOB, and though it closely follows the semantics of virtio-gpu in most cases, it is in theory independent of virtio or any other transport.
Main user is [qemu][qemu-gpu-impl], but there also appears to be a [standalone virtio-gpu vhost-user][qemu-vhost-impl] implementation that uses virglrenderer in qemu/contrib.
virglrenderer's public header is at [src/virglrenderer.h][public-header]. This document attempts to outine the public API and contract, but you should look at the header for an authoritative source of truth since semantics described here could be slightly wrong or have changed, a
