| |
From: Andreas Herrmann <andreas.herrmann3@amd.com>
Commit 24d9b70b8c679264756a6980e668b96b3f964826 (x86: Use PCI method for enabling AMD extended config space before MSR method) added a message when IO access to PCI ECS was enabled via access to the NB_CFG PCI register. This can lead to a bogus message like
[ 0.365177] Extended Config Space enabled on 0 nodes
which is misleading because IO ECS access is subsequently enabled for AMD CPUs (that support this) by modifying the corresponding NB_CFG MSR.
Furthermore it's not "Extended Config Space" that is enabled by this register setting. It's the IO access that is enabled for extended configruation space.
IMHO the ambiguous message needs to be cancelled.
