We learned one simple lesson, the past 10 years: if you want good ARM support, it has to come from the vendor. Nobody else can reverse-engineer devicetrees or GPU drivers with a remotely comparable release cadence. Linux has supported new x86 chipsets on day-1 since forever now; compare that to Broadcom or Apple Silicon's "best effort" community support that often takes years to boot into a graphical environment. Forget about stability or regression testing, it's a tinkertoy.

This is a shame because all the ARM licensees worth buying hardware from always have higher margins on smartphones or services. They have no commitment to supporting the PC or server market, let alone the software they use or featureset they depend on. It's no wonder that ARM adoption is stalling on the runway while Power11 gets upstream kernel support and RISC-V displaces integrated ARM ICs. Their only stakeholder is making their money off iPhone apps, not professional software.
