Description IBM Bug Proxy 2010-06-23 13:01:11 UTC 
=Comment: #0=================================================
SUBRATA MODAK <Subrata Modak <subrata.ibm.com>> - 
Active Memory Sharing seems not enabled in Fedora 13 ppc64 even with the Internal Build 
tree which is supposed to be synced now with the Fedora 13 GA tree.

Machine Information:
# uname -a
Linux alien5.ltc.austin.ibm.com 2.6.33.4-106.fc13.ppc64 #1 SMP Mon May 24
14:08:08 EDT 2010 ppc64 ppc64 ppc64 GNU/Linux

# cat /etc/issue
Fedora release 13 (Goddard)
Kernel \r on an \m (\l)
# grep -i CONFIG_PPC_SMLPAR /boot/config-2.6.33.4-106.fc13.ppc64 
# CONFIG_PPC_SMLPAR is not set
# grep -i CONFIG_CMM /boot/config-2.6.33.4-106.fc13.ppc64 
# echo $?

# grep -i CONFIG_SPARSEMEM_VMEMMAP /boot/config-2.6.33.4-106.fc13.ppc64 
CONFIG_SPARSEMEM_VMEMMAP_ENABLE=y
CONFIG_SPARSEMEM_VMEMMAP=y

Following changes in the config file are needed to support Active Memory Sharing:
CONFIG_PPC_SMLPAR=y
CONFIG_CMM=y

Following change in the config is needed to support DLPAR memory remove:
CONFIG_SPARSEMEM_VMEMMAP=n

This kernel is still not available with our Internal Builds. Will test once the
mentioned kernel is available.
