"Support" exists (for power management and load balancing); but it's not like a normal user-space program can tell the kernel "prefer (but don't restrict to) a little core for this work"; and not like programmers can do something like "#pragma CPU_type_preference(little)" in a few places and let the compiler propagate the optimization hints throughout the call graph.

Oh, so at some point in the future we can just say "software for CPUs without AVX-512 is legacy software" to change the motivation for it, and limited support for heterogeneous CPUs (pinning older software that doesn't use AVX-512 to E cores) becomes good?

use that AVX512 hardware, since 99% of users (today and not in 15+ years

Perhaps; but that only dilutes my objection without invalidating it. There'd have to be some programmers where "some performance improvement" (from AVX2) doesn't justify the hassle but "more performance improvement" (from AVX-512) will; and some programmers who'd benefit from things AVX2 doesn't provide (mask registers, half-precision floats).

Of course a majority of user-space is people that don't care much about performance in the first place; and some people that push SIMD code out of their program into libraries to make porting easier; which skews the stats towards the "99% in libraries".

To be honest; I think Alder Lake is mostly backwards. You'd want P cores for sequential/non-parallelizable work where you don't have much reason to care about AVX-512, and E cores with AVX-512 for doing parallelizable work efficiently (at lower clock frequency, etc).

Using a 256-bit ALU for AVX-512 on E cores doesn't help much if the entire point of having E cores is to do more in parallel per cycle at a lower frequency.

It'd only take (e.g.) 5th generation Xbox having custom "homogenous Zen 4" chips. Once Windows supports homogenous CPUs (for XBox games) Windows supports homogenous CPUs (for everything), and everyone else (Linux) gets stuck with it whether they like it or not. It certainly wouldn't be the first time a game console did something unusual (PlayStation 3),

Ern, no? In the real world, (some) high performance software developers use GPGPU despite the fact that it has the worse and most hacky "programmer/user experience" you could possibly imagine; and nobody says "Oh, let's just use the parts of the ISAs that are common between CPU and GPU" because there are no common parts.

Do you think this would suddenly change if it was (e.g.) eight 80x86 P cores with AVX-512 and sixteen 80x86 E cores with AVX-2048 (and there were common parts of the ISA)?
