Hi Guys,

Has anyone been doing any development in the area of enabling 4G for
any PC that doesn't have an option in the BIOS?  The Mac OS X sees the
full 4G, but Linux does not.

tdamac ~ # uname -a
Linux tdamac 2.6.30-rc7-dirty #3 SMP Fri Jun 5 21:24:29 MDT 2009
x86_64 Intel(R) Core(TM)2 CPU T7400 @ 2.16GHz GenuineIntel GNU/Linux

I'm curious if there's some simple piece of code that can disable
legacy PCI assignment of that extra 1G that Mac OS X does, but not the
Linux kernel?  I know I disabled something called legacy mode or
something, in one of my 64 bit machines, and the 4G then showed up.
But, seeing the Mac uses EFI, I'm unable to do that.

If no one has done any development in that area, does anyone have any
idea where to look up the technical aspects of adding this code, and
where in the kernel I would put it if I found out how to do it?

Thanks.

I bet you should set CONFIG_HIGHMEM64G or use x86-64 kernel because of
1G of memory hole somewhere below 4G.

My dmesg is below.  Unfortunately, I will not be able to help with
testing for a bit now.  I just got my memory today, and it's either
bad, there's something wrong with the Macbook, or the memory doesn't
work with the Macbook as Kingston claims it does.  So, I have to send
it in for RMA I guess.

The e820 map is the way that the BIOS tells us what memory is available. 
  Here it's only showing about 3040MB of usable memory, all below 4GB. 
The usual way that it should work with 4GB of RAM is that the portion of 
the  memory corresponding to the address space occupied for PCI devices, 
etc.  gets relocated above 4GB. However either the chipset in your 
machine doesn't support memory hole remapping, the BIOS doesn't bother 
to use it or it doesn't bother to tell Linux where it is..

Do you know if Mac OS X is actually use all 4GB, or is it doing the 
"well, we can see there's actually 4GB installed but we won't mention 
that we can't use it all" trick, like some Windows does?

That is very well possible.  It did appear to have over 3G free, if I
recall correctly.  I'll try booting into Mac OS X again and see.

That's my graphics card though, not my motherboard chipset.  The
chipset is ICH7.

ICH7 is the southbridge. 945 is the northbridge and includes the memory 
controller. It can only access 4GB of address space, which includes PCI 
and any other memory mapped resources. This means that it's not possible 
to use 4GB of RAM.
