The Raspberry Pi Desktop OS 64 bit

Mon Sep 04, 2017 5:58 am

hi,

is There any Raspberry Pi Desktop OS 64 bit? I would be grateful if you could send its download link.

You can get a 64 bit os in nearly every distro (except raspian) I think. What is your normal linux distro of choice?

thanks for replying, my choice was raspbian Jessie and wheezy before, now I should chang it. do you know which 64bit distro is better?

By what criteria do you measure "better"?

Or to put it another way, what is wrong with Raspbian?

Opensuse was I think the first and possibly the best. I have a Ubuntu bias and created a lubuntu ISO for the pi 3 (viewtopic.php?t=190511 ) so you can use that if you just want to try arm64. The boot is really slow compared to raspbian, but that is mainly due to the 'live' nature of the iso, and an actual install is faster to boot.

I don't have any problem with raspbian but I want a 64 bit os and I couldn't find rsbian 64. thus I want to switch another distro. the most important metric to me it's the act of the os on the installation and execution software program.

thanks for reply, I test one distro based on Debian and it was really slow special in booting.

Still puzzled. If there is nothing wrong with the Raspbian OS you are using why do you need to change it?

Normally the only reason for going to a 64-bit version of an OS is so that you can use more RAM. That is not a consideration with the Pi since the hardware is limited to 1GB RAM this is not a reason for going to a 64-bit OS.

There is normally no performance benefit for going to 64-bit, and 64-bit programs are typically larger than the 32-bit equivalent which is not a good thing on the Pi with limited RAM.

You are unlikely to see any improvement in performance on the Pi when going to a 64bit OS, unless the app is 'tuned' to 64bits. There are some areas where 64bits does give slightly better performance, but not many.

Sometimes. I have a program which is 79k in 32-bit mode and 72k in 64-bit mode.

There are twice the number of registers (31 general purpose registers and a very handy zero register), so for example, there is often less need to adjust the stack frame in each function.

Its true that 32-bit Raspbian is perfectly adequate for 99.999% of users.
I fiddle with a little assembler now and then and I much prefer the modern A64 instruction set and the new NEON. Not typical though!

I think a lot of these discussions miss a crucial point: that is the application support. ARM is not a priority for many application developers, but if they are going to have some sort of arm machine then it will probably be arm64. So I think you are more likely to have Firefox jit working in arm64 than armhf etc. Examples of this can already be seen on the forum, see the ff55 and the llvmipe mesa discussions.

I would expect that if they want a Arm board, then the Raspberry Pi is the obvious choice. 15M sold.....that s much bigger market than any officially 64 bit ARM board.

You've clearly never compiled Firefox. They are not going to be working on a pi.

Maybe not for the compiling, but for the testing on a target machine it does make sense.

I don't think it necessarily works like that. From a ff bug report:
I don't think you should expect swift action on this. ARM Linux (other than Android) is a tier-3 platform for us and we do not dedicate resources to it, depending instead on distros to support it and submit patches: https://developer.mozilla.org/en/docs/S ... igurations.
Of the 15m sold, a large number of raspberries will be sitting unused in drawer, a large number will be doing something embedded, a large number are too slow to do anything reasonable on a desktop. Pi usage will be a tiny percentage of the total number of Firefox users.

Probably. But figures like that are impossible to predict with any accuracy. Firefox is a bit pants now anyway. We build and test Chromium (and also add new features), so that is the way to go. If Firefox don't want Raspberry Pi business, that is their lookout. I expect about 30M-40M Raspberry Pi's in the field within 5-7 years. Even with a high 'drawer' rate, that is still a lot of kit. Add in other ARM devices, which is a market that is only going to get bigger, and FF's decision may start to look a bit like the decision to write Scratch 2 in Flash.

Personal opinion, but anyone who isn't interested in ARM platforms for the future might need to look again. Once we have a full desktop class ARM device in the field, the market is going to explode. Cheap, low power, does everything you need. Only disadvantage, no Windows.

The 835 is an Octa-Core 64bit ARM CPU and supports DDR4 memory, so it will be no worse than Atom CPU boxes..

They're only going to get faster though, they have to start (or restart) somewhere.
The knowledge from the IoT Core and Pro Core (I think it's called for the 64bit version) will of course help as they move Windows forward.
I assume there is a large server market of Arm devices they probably wish to tap into at some point.
Cover your bases at this point in time.
