There was a time when care had to be taking when buying hardware if the goal was to run Linux on it. The situation has improved considerably in recent decades, and unsupported hardware is more the exception than the rule. That has, for many years, been especially true of Intel hardware; that company has made a point of ensuring that its offerings work with Linux. So it is a bit surprising that the IPU6 image processor shipped with Alder Lake CPUs lacks support in Linux, and is unlikely to get it anytime soon. The problem highlighted here goes beyond just Intel, though.

It is fair to say that some projects are rather more concerned about preserving ABI compatibility than others; the GNU C Library (glibc) project stands out even among those that put a lot of effort into preserving interface stability, So it may be a bit surprising that a recent glibc change is being blamed for breaking a number of applications, most of which are proprietary games. There is, it seems, a class of glibc changes that can break applications, but which are not deemed to be ABI changes.
