It doesn’t sound like anyone outside of Intel and Microsoft actually knows how this works. How are Linux and the BSDs going to be able to support this?

[yvdriess → mnd999]

The way it usually goes, Intel submits a kernel patch.

Only when they are motived enough, PowerVR, Kaby Lake Vulkan?

[wmf → pjmlp]

Those products sold almost no units. Alder Lake will be Intel's mainstream CPU so there should be Linux support.

[pjmlp → wmf]

PowerVR had Linux support, just not the way FOSS advocates wanted it.

Android phones have had big.LITTLE a while now, you would hope that scheduler support has matured in that time.

[bitL → Thev00d00]

Android phones don't have real multitasking; SailfishOS might be a better example.

[vbezhenar → bitL]

Android phones run real Linux kernel with real multitasking. How multitasking exposed in UI is a different question.

[bitL → vbezhenar]

That's a bit like saying "your car has 5 gears but you can only use the first one". In practice you have 1 gear.

[detaro → bitL]

No, that doesn't make any sense.

The system and apps on it make use of multiple cores, that's all that matters for the scheduling point.

[dgan → mnd999]

Do they need to support this? Another proprietary blob that takes decisions what process to run where? Just asking

[mnd999 → dgan]

If Windows is making changes at scheduler level to support it, I would think yes, they do.
