Red Hat Patch Proposal To Split FBDEV Core Support

Phoronix - Fri, 08/27/2021 - 18:34
For nearly the past decade there has been calls for deprecating the Liux kernel's frame-buffer "FBDEV" device code though the code remains within the kernel.

But a patch proposal out of Red Hat would further split-up the FBDEV core support to allow less of it to be built...

So, yeah, I had to figure out how many weeks between 2021-08-01 and 2021-12-31 inclusive.

This is the perfect sort of problem to solve with a tiny Groovy script.
