DRM Splash Screen Updated To Simply Drawing A Colored Background, Displaying A BMP Image
Back in October was an initial proposal for a DRM splash screen client for the Linux kernel that would be primarily useful for embedded systems for rendering a simple "splash screen" when updating the system firmware/software, early display activation at boot, during system recovery, or similar processes. Sent out today was a second revision to the DRM splash screen code.
There is already Plymouth as a great boot splash screen solution for Linux systems while this DRM splash screen primarily aims to fill different niches mainly in the embedded space when needing to display a simple graphic or similar. Stemming from objections raised during the original round of code review, user-driven functionality like configurable messages and a progress bar was dropped from this proposed code. Those solutions are best off left to user-space tooling.
With these v2 patches, the stripped down functionality of the splash DRM client is left for drawing a simple colored background or loading a BMP image. The BMP image can be supplied via built-in to the kernel or loaded from the file-system or supplied by the EFI BGRT as the boot-up logo found with most modern systems.
Those interested in this proposed DRM splash client functionality can learn more about it via the v2 patch series.
