Current kernels tell the firmware that they can handle having memory represented in the /ibm,dynamic-reconfiguration-memory node, which is a more compact representation than having it represented in multiple /[EMAIL PROTECTED] nodes. Therefore firmware reports most of the memory in the /ibm,dynamic-reconfiguration-memory node you have here: > linux-2.6.26-rc1: > > <snip> > 0 > dev / ls > ... > 000000caf1b8: /PowerPC,[EMAIL PROTECTED] > 000000cb0120: /[EMAIL PROTECTED] > 000000cb83d8: /ibm,dynamic-reconfiguration-memory and only gives you one /[EMAIL PROTECTED] node, which represents the real memory area. See sections C.6.2.3 and C.6.6.2 of PAPR for more information.
