    Default Raspberry Pi Is Running Well On Wayland/Weston

    Phoronix: Raspberry Pi Is Running Well On Wayland/Weston

    The low-cost low-end Raspberry Pi ARM development boards are running quite happily now with Wayland and using its Weston compositor. The performance is better than with an X.Org Server and Raspberry Pi's Eben Upton has called it the future of Linux desktop graphics...

    Raspberry Pi is old legacy ARMv6.

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

    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.

    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

    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!

    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...

    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

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

    The released raspberry's graphics driver is an open source RPC interface to a proprietary firmware and shares none of the FOSS graphics driver infrastructure (drm mesa ...). Therefore a new backend is necessary.

    I'd say if Nvidia is to support wayland, this probably would be how it is done --- release an interface to its proprietary blob and (either nvidia or the wayland developers will) write a weston backend for it.

    The RPI has a CPU and a GPU, but also a hardware compositor, so writing a dedicated backend improves performance a lot (see links posted above, as well as this one).
