I know nothing about what it takes to develop a laptop. Are these issues (BIOS updates, virtualization support, USB4 support, etc) something the laptop manufacturer needs to develop solutions for in-house? Wouldn't that be the job of Qualcomm? Or are Tuxedo saying that these things aren't supported on the Linux side yet? Qualcomm claimed to be contributing to the kernel last year, so idk if that just hasn't happened yet or if they just lied.
Either way this is disappointing, but understandable. There's no sense in working to release a laptop with previous-gen hardware that's not going to be competitive.
