Will Puppy work with Intel DUO core?

[divisionmd]

Oh perfect! Great news!

But how do i check so Puppy 2.17 actually uses the multicore?

When im trying to activate "multicore processors" from Vmware player within Puppy it tells me its not activated.

Best regards,

Use cat /proc/cpuinfo to produce an output similar to the following. If you have 2 cores there should be 2 processor descriptions like in the example output below - one for processor 0 and one for processor 1.

Code: Select all

{/proc/cpuinfo out cut from post above}

I think at least two basic conditions must be true before you will get the cpuinfo output posted.

condition 1 == 2 cores
AND
condition 2 == kernel compiled to support it

Else only cpu 0 will be displayed and no hint of a cpu 1

-----------

Or hopefully, I misunderstand the context due to a brevity factor and not seeing where to put it into context.

[Leachim]

Sorry, my posting was a bit misleading! I meant that you will only get a similar output if your kernel supports multiprocessing!

Otherwise it might show a single entry. This entry might contain the word "dual core" but the second core will not be used until there are two entries displayed!

When i type that i get this:

processor : 0
vendor_id : GenuineIntel
cpu family : 6

Does it mean Puppy has found and is using the Duo core?

Quite to the contrary. It says you have Intel(R) Core(TM) Duo CPU T2350 @ 1.86GHz, which you do.

But no CPU 1 is listed. In this instance we start count from 0

@Leachim, I'd appreciate it greatly if you could do a little hand holding and point me to where I could get the cutting edge kernel that would work with version 2.17

[divisionmd]

Ok so this means Puppy has not detected both cpus?

Thanks,

Hello,

Ok, so its possible to use duo core cpus then? but i need to attach a patch to the kernel, something to make it work?

Please explain on how to do this. Is there a .pup file i can use to patch my Puppy 2.17? then to use duo core.

Thanks,

Best regards,
Johan

[divisionmd]

Hello All!

Can any Puppy expert put a final word on this question?

- I run puppy from a Duo core Pc and when i type "cat /proc/cpuinfo" it only lists one CPU.

- Can i in some way fix this so Puppy detects and uses both? if so how can i do this.

Thanks,

Best regards,
Johan

I am no puppy expert by any measure, but take this as an interim answer to your question:
1. Standard puppy (and most of puplets out there) can only use one core, even if your computer has multiple cores.
2. Yes you can fix it, find a new "kernel" that is configured for multiprocessing (=SMP kernel). Leachim already gave the link above of where to get it. It is not yet packaged, so it's rather tough to use.

cheers!
Posted from Puppy 3.01 running on Pentium Dual-core (with only one core working, the other is sleeping).

[divisionmd]

Thanks James Bond!

Then i will try to get that patch to work on my Puppy 2.17. Have you tried it?

I will follow leachim´s link and read more.. .

This forum probably old but this may be helpful. Found this forum helpful to get Puppy 5.2.5 on a core dual 3.2ghz Gateway 510xl (intel equipment). I had two Puppy cd's, 4.3.1 and a 5.1 that did not work, , said, something like, "vm linuz load failed," and stopped, somewhere said, "failed to load partition." For what it's worth. Read here that it could be the Puppy CD was defective in some way, didn't believe it but as a last ditch effort to load Puppy on what seams a powerful but 2004 machine, I downloaded Puppy 5.2.5, burned it to a cd on my mac (old ancient g4 with outdated panther, cross my palm and I'll tell you more Steve Jobs), then booted (bios set to boot cd first) and it continued past trouble spot. Soon flashed the puppy.iso words across the screen real fast...then it was a blank dark screen for about 30 seconds ...it's do'n something, the monitor switch still showed green. Then got the Puppy flash pic. and loaded the desktop, no problem connecting with auto dhc and is running great. Found Puppy Linux does run on this core dual Intel processor and board, at least Puppy 5.2.5 does.

... Found Puppy Linux does run on this core dual Intel processor and board, at least Puppy 5.2.5 does.

I not sure it this will make anything better, but there is one Puppy that is "geared" toward multi-core processors.

It is ICE Puppy. I have been using this version of Puppy built for these modern multi-core processors since the author of the distro began offering this to the community. I continue to use it in LiveCD mode since I began.

Its a special Puppy for 32bit Multi-cores. And, there is a PUP525 version for multi-cores, as well, called PUP539.

Hope it helps.

[puppyluvr]

Hello,
Actually, there are several builds on the multicore/highmem enabled kernels...
Stu90`s 525 lite for example...
Someone is even doing a Compiz build...
But IcePuppy is the cream of the crop...
14 and 15 cover both older or newer hardware...
Very comprehensive forum thread as well...

[mill0001]

Hi,
I've been using lupu_525 with quad core cpu since it came out. It works just fine. I put parameter: max_cpus=x (where x is your number of cores) on kernel line of menu.lst. You can see if all cores are active by typing htop in terminal. Have fun.
