The FBLOG driver, which is a kernel frame-buffer driver just for displaying logs from the Linux kernel, continues to be revised and the code's author wants to push the driver into the mainline Linux kernel.
Last month I wrote about FBLOG as a kernel driver just for displaying logs
that was written by David Herrmann -- the developer trying to kill VT support in the kernel (CONFIG_VT
) and has been working on KMSCON
and proposed Wayland with virtual terminals
. In the past month, the FBLOG Linux driver has now undergone three revisions.
This driver to replace fbcon simply prints the kernel log to all connected frame-buffers. The third version of this code incorporates various fixes and improvements raised by developers in recent days. Herrmann says today on the kernel mailing list
, "It would be nice if someone could tell me what tree this will go through or how I can get it into linux-next as I have no idea who is maintaining fbcon. If there are other major or minor issues, please tell me so I can work on them."
Besides what he's already done with the frame-buffer kernel log driver, David is looking at improving the render path using DMA-BUF and partial re-draws plus a panic handler.
