ARMv8.1?

I have RPi-3/Jessie here, so if you tell me the magic command to check I'll find out.

lshw is usually a goldmine on most linux systems (don't know about the pi3)

Finally, Zippy drives his 1958 RAMBLER METROPOLITAN into the faculty 
dining room.

It's a Cortex A53 so I believe that makes it v8.0.

Yes, a good point, working throught that manual now.

Thankyou

If you are running a 32 bit OS, it will look like a 32 bit processor, and won't give you any information on it's 64 bit capabilities.

You also don't need to install lshw, lscpu comes as standard on Raspbian.

Which on a Pi3 gives:

12GHz? that's pushing...

Only 12 GHz?

As the units are given as MHz I make the numbers to be 12 THz and the formating well borked.

Now is that formating "borked" due to the posters locale or really borked? Tries lscpu and a zero and 2b, it's locale and four 4 decimal places.

Dave.

Have you had a lok at /proc/cpuinfo?

-TV

Not b0rked, perfectly fine & correct (for my locale). See my follow-up.

Fun:

I have not even taken it out of the box, which will wait until I'm au fait with the machine code.

Remember you'll need a 64 bit OS, instructions here:-

No region has 4 noughts after a comma separator, dear.

That?s nothing to do with the locale, the program just asks for four decimal places.

--

That depends on what function the comma is performing. As a decimal point there can be any number of digits after it. As a thousands seperator only three digits (in base 10 at least...).

--
Cheers 
Dave.

It looks as though more nationalities use a comma for the decimal point than use a full stop, which surprised me a bit. See here:
