Subject: [PATCH] x86_64: checking aperture report for node instead of cpu v2
Date: Tue, 15 Jan 2008 10:31:45 -0800 [thread overview]
Message-ID: <200801151031.46279.yinghai.lu@sun.com> (raw)
In-Reply-To: <20080115132253.GC7025@elte.hu>
[PATCH] x86_64: checking aperture report for node instead of cpu v2
currently when gart iommu is enabled by BIOS or previous we got
"
Checking aperture...
CPU 0: aperture @4000000 size 64MB
CPU 1: aperture @4000000 size 64MB
"
we should use use Node instead.
we will get
"
Checking aperture...
Node 0: aperture @4000000 size 64MB
Node 1: aperture @4000000 size 64MB
"
