back to article RedSleeve does RHEL-ish clone for ARM

If you are tired of waiting for Red Hat to do an official port of its Enterprise Linux commercial distribution to the ARM architecture, well then Red Sleeve Linux has just what you are looking for. Like many of you, El Reg had no idea that RedSleeve Linux, a port of the upstream RHEL reworked to run on ARM RISC processors …

Re: Raspberry Pi?

Indeed it does run on the Pi. This should get you started on the Pi if you are lucky enough to have received one already:

ARMv5?

ARMv5 really? It's a waste of time for servers as it relies on old HW and doesn't use the HW components of modern processors. There's a reason that no one has done a clone of CentOS on ARM before and that's because the compilers that ship with EL6 don't support ARMv7 or hardware floating point and there's no point dealing with the compatibility of older HW as there's no enterprise software that needs it. Basically it's completely behind the game before it starts and won't use any of the amazing features of the new HW in Calxeda or Dell servers.

Re: ARMv5?

Peter 68, Allow me to correct you on a few points where you appear to have an excess of opinion and a lack of facts and understanding.

1) It doesn't rely on old hardware. You can happily run armv5tel targetted code on ARMv7 CPUs. Targetting armv5tel ensures the widest hardware compatibility.

2) ARMv7 hardware runs armv5tel built code about 2x times faster clock-for-clock than the best ARMv5s (e.g. Marvell Kirkwood). The armv7l targetting doesn't actually gain you much.

3) armv7hl (hard-float) target will gain you performance in FPU heavy applications (rendering, various mathematical analysis applications). RSEL6 is aimed at servers where the benefit is at best questionable (and realistically close enough to non-existent it's not worth mentioning). Apache, PHP web applications, MySQL and other most popular server applications don't benefit a great deal from speeding up floating point operations. Note that the hardware FPU will still be used if available even if you use an armv5tel soft-float target.

4) What features exacly are you referring to that would be unused when running an armv5tel targetted distribution on the Calxeda and Marvell Armada SoCs that the mentioned servers use? Can you name one?

Red Sleeve?

Well played, very well played.

Made me LOL anyway.

Next you'll say...

... you have to _hand_ it to me (in a punny reference to the logo), right? :^)
