current logic is hardcoded, as in the original spkmodem-recv. with this change, small differences are observed and averaged, then the detection thresholds are adjusted accordingly. the existing macros serve as a baseline, but real signals differ. with this change, we therefore account for possible drift in timings, which can change in real-time; the old code could possibly get out of sync beccause of that, which may have resulted in corrupt characters on the screen. this change therefore should make the output a bit more stable. the detection window is continually adjusted, so that the output timings don't drift. the tolerances are automatically adjusted based on base timings (see new define in patch) Signed-off-by: Leah Rowe <leah@libreboot.org>

Libera IRC
Libreboot provides libre boot firmware on supported motherboards. It replaces proprietary vendor BIOS/UEFI implementations, by
- Using coreboot to initialize the hardware (e.g. memory controller, CPU, etc.) while minimizing unwanted functionality (e.g. backdoors such as the Intel Management Engine)
- ... which runs a payload such as SeaBIOS, GRUB, or U-Boot
- ... which loads your operating system's boot loader (BSD and Linux-based systems are supported).
Why use Libreboot, and what is coreboot?
A lot of users who use libre operating systems still use proprietary boot firmware, which often contain backdoors and bugs, hampering user freedom and right to repair.
coreboot provides libre boot firmware by initializing the hardware then running a payload. However, coreboot is notoriously difficult to configure and install for most non-technical users, requiring detailed technical knowledge of hardware.
Libreboot solves this by being a coreboot distribution (in the same way that Alpine Linux is a Linux distribution). It provides a fully automated build system that downloads and compiles pre-configured ROM images for supported motherboards, so end-users could easily fetch images to flash onto their devices.
Libreboot also produces documentation aimed at non-technical users and excellent user support via IRC.

You can check bugs listed on the bug tracker.
You may use Codeberg pull requests to send patches with bug fixes or other improvements. This repository hosts the code for the main build system. The website lives in a separate repository.
Development is also done on the IRC channel.
