[Trisquel-users] Is the AMDGPU driver considered Free Software?

[gert . otten . 1998]

So it's been a while since I've been here, mainly been dealing with  
depression, but that's a personal thing so not gonna get into it here.  
Anyhow, I've been looking for a replacement computer, since this one has a  
proprietary BIOS, NVIDIA graphics, and Intel WiFi. It currently runs  
Trisquel/Mint. Mint for some games that unfortunately require the proprietary  
NVIDIA driver to run decently, as development on Nouveau seems to be somewhat  
stagnating. So after a couple of searches, I found out that the AMDGPU driver  
is now "open source" and part of the kernel. This means that Linux-libre  
should support it too, as Linux-libre supports all hardware that is supported  
by the kernel itself, right? I've been checking out some laptops at both  
Minifree and Technoethical, but also came across Purism, they're working  
towards RYF-certification, though they're not quite there yet. So, I could  
either wait for them to make a fully libre laptop, with decent hardware, or  
build my own PC using one of the RYF-certified motherboards. I came across  
the TET-D16 and the ASUS KGPE D16 on fsf.org, and figured, well, maybe if I  
slap an AMD video card in one of these, I could get a decent gaming  
experience with only libre firmware. Is this true, or is there some caveat?

Thanks in advance to anyone who can help out!
