Raspberry Pi Is Running Well On Wayland/Weston

[Teho]

Why does the RPI needs its own backend? I thought wayland/weston was supposed to be rather hardware agnostic as long as there was support in the graphics driver.

Please enlighten me!

These two blog post explain why. It's about supporting the hardware specific features of the VideoCore in Raspberry Pi.

Silvermont CPUs have at most 4 cores. 8-core version is missing.

Yeah, but it might still be competitive with Qualcomm Krait and Samsung Exynos.
Apparently the Silvermont is targeted for tablets and is said to have good performance and battery.

A 4 GHz ARM would probably get toasted by a 3 GHz Intel.
Intel is making some good Atom processors to compete with ARM though. Like the upcoming one built on the Silvermont architecture.
I think it will be pretty competitive with ARM processors.

That would be great. I'm dreaming of a 4Ghz ARMv8 processor with 8 cores for the desktop. Much lower power consumption than Intel and AMD and good performance.

But yeah, that would be really nice though.
Imagine it passively cooled too.

Drivers need to support X server \ Wayland \ Mir internally. It's why Intel was in the position to reject the Mir patches.

Well, I think. I was just informed otherwise at least in one case. I guess it depends on the driver...

IBM CPUs cost like 10 times more than Intel ones

Yeah lol. Note the edit I added just before you posted
10 times is actually a very cheap estimate. The IBM Power 750 Express server we were just consulted to buy retails at 36K

Sounds like an IBM POWER7. The instruction set is RISC like ARM's and they have plenty of 4Ghz\8 cores offerings.

p.s. it's a joke... obvious one to me but I just realised I might stair up some trouble... IBM jokes... Well, it was funny a decade ago

Raspberry Pi is old legacy ARMv6.

I would love to see a single-board computer with ARMv8 and 64-bit.
