Following yesterday's release of Linux 6.4, the FSFLA team has released GNU Linux-libre 6.4-gnu as the newest version of this downstream kernel that aims for "100% freedom" with removing any kernel remnants that depend upon non-free-software microcode/firmware or other binary blobs as well as removing the ability to load proprietary kernel modules.

The release announcement for the GNU Linux-libre 6.4 kernel sums up this cycle's changes as:
"Adjusted cleaning up of x86 microcode docs, x86 Android tablets and QAT crypto drivers to account for moved files in the source tree. Dropped cleaning up of vs6624 driver, removed upstream. Neutered op-tee's, rtl8710b's and qcom's Cloud AI blob loaders. Cleaned up bluetooth nxp protocol support. Cleaned up blob names in qcom aarch64 dts files."

More just neutering of kernel code that relates to potentially non-free-software standards. Downloads and more details on the GNU Linux-libre 6.4 kernel via GNU Linux-libre mascot

With the GNU Linux-libre 6.4 release they also posted this new graphic of Freedo, the Linux-libre mascot. If this picture were to be accurate, that dual monitor setup is likely running without any hardware acceleration considering desktop GPUs for years have required binary blobs for their microcode. The best case would be Freedo rocking out with a decade-old GeForce GTX 700 series graphics card with the Nouveau driver that doesn't require any closed-source microcode for hardware initialization.
