[opensuse] Kernel only see 3 of 4GB
I've installed additional 2GB of RAM into my Thinkpad Z61p. My kernel (latest SUSE-10.2-64bit) sees only 3GB of 4GB! Do i have to setup anything to see the whole memory?

I've seen this reported elsewhere (on a ThinkPad T60) and it was basically a restriction in the BIOS that prevented the OS from seeing all 4GB of RAM. You might want to look for a BIOS upgrade, or setting - but I'd be prepared to be disappointed if I were you.

Yes, it is. But in order to get a 32bit kernel that supports PAE, you need to replace the installed kernel-default package by the kernel-bigsmp one. And even then you might not see the whole 4 GiB, because the BIOS reserves some address space for PCI devices.

Some (many) 64-bit processors have 32-bit compatibility modes. And most mainboards support multiple processors. Mainboard BIOSes for boards that support such processors have to be able to be configured for all the processors they support. Since there's no one-size-fits-all approach to this issue if both 64 and non-PAE 32-bit chips or operating system can be used, they make it a BIOS configuration option. So you, as the person who knows what processor, how much RAM and what OS are being used, must take this information and choose a suitable setting for those BIOS options.

Yes, but as i described before, two identical machines, Lenovo Z61p, 4GB RAM, Dial 2 Core T7200 with latest BIOS. Running with Vista 32bit: 4Gig available. Running openSUSE-10.2-64bit: 3Gig available (as with Ubuntu-7-64bit) So maybe BIOS is configured for PAE and has problems with 64bit kernels? Should i test with Vista-64bit?

Broken BIOS I'd suggest. The BIOS has to reserve address space below 4 GiB so that 32 bit devices (i.e. PCI) may be addressed. How much address space is reserved is up to the BIOS. RAM in that range is not accessable unless the BIOS offers an option to remap that range to somewhere *above* the 4 GiB theshold. Only then can an OS kernel access that RAM. So if the BIOS doesn't have such an option, this 'hidden' memory is wasted and could just as well be removed.

That seems unlikely.

That's what I thought too.

Folks, how many times does this need to be repeated? The BIOS *has* to reserve some address space below 4 GiB for I/O puposes, e.g. 32 bit PCI devices. RAM in that range is not accessable. Therefore some BIOSs offer the option to remap that RAM to above the 4GB threshold. In order to access this remapped RAM, you either need a 64bit kernel (if you're using a processor that supports AMD64/EM64T) or a 32bit kernel with PAE enabled (i.e. kernel-bigsmp).

Check to see if there is a setting in the BIOS for Memory Hole remapping. I am far from an expert, but my understanding is that memory for the PCI devices is reserved in the 3 GB to 4GB range.

In openSUSE 10.2 the SMP / non-SMP distinction is gone. Only a generic, SMP-capable kernel is distributed. Furthermore, SMP / non-SMP distinction does not relate to physical memory addressing range. That's PAE, which the 10.2 kernel is also capable of utilizing (on 32-bit processors that have the PAE hardware).

What, then, is KMP? I've never heard of it and cannot find any relevant information on the Web.
I don't know much about the term either... but it means, "Kernel Module Packages".
google "kmp kernel" Novell
Indeed - kmp = kernel module package. I suspect the original reference actually meant the PAE kernel. Even this will not be sufficient, as it seems the problem is a hardware limitation. Besides which, PAE is an ugly (but necessary) workaround to allow 32 bit hardware to utilise >4GB RAM. (Not =4GB, which a non-PAE kernel should be able to handle) Jon -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Yes, of course I did that (and / or variations), and found nothing relevant to physical address extension. I really don't think KMP in any way equates with PAE. Randall Schulz -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

In openSUSE 10.2 the SMP / non-SMP distinction is gone. Only a generic, SMP-capable kernel is distributed.
Look closer and you'll see that there is still more then one kernel supplied with 10.2.
Furthermore, SMP / non-SMP distinction does not relate to physical memory addressing range. That's PAE, which the 10.2 kernel is also capable of utilizing (on 32-bit processors that have the PAE hardware).
You still need kernel-bigsmp to get a kernel that supports PAE. Philipp -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
