For Fedora, linux-hardware.org says 78% use EFI and 16% have Secure Boot enabled. Not a very good data set, though Fedora telemetry wouldn’t be either.
Of ~ 1K linux boxes in&around my env -- bare metal & VM, servers & desktops -- ~ 550 are now running fully updated F34. Of those, ~ 95% are AMD; remainder are Intel. No ARM. Of the total, per a quick survey, ~ 15% have _no_ avx/avx2 support ~ 40% have avx-only support rest have avx/avx2 support NONE of the no-avx or avx-only machines are "suffering" from any performance problems for their current business/technical usage. Here, the 1st response to "my OS suddenly no longer supports this hardware" will seldom-if-ever be to replace the hardware. At best, I'll freeze the machine's s/w base @ last-supported, and look to replace the OS. There are real/significant costs to H/W upgrade/replacement -- both capital & expense; Planning & budgeting for them is often on a multi-year timeframe. Particularly at scale. And my env is relatively quite small on the global stage. This seemingly endless stream of drop-the-old-hardware discussions, even if reasonable for some, is a cause for tangible concern that I've gotten myself into a tactical, eggs-in-one-basket mess. Again. With RockyLinux today at GA, time to explore/compare a 'plan B' & whether it provides some differently sensible support planning. Or whether YA-x-distro firedrill is inevitable.
