Subject: [PATCH 22/46] tools/testing/cxl: Expand CFMWS windows
Date: Thu, 23 Jun 2022 19:47:47 -0700 [thread overview]
Message-ID: <165603886721.551046.8682583835505795210.stgit@dwillia2-xfh> (raw)
In-Reply-To: <165603869943.551046.3498980330327696732.stgit@dwillia2-xfh>
For the x2 host-bridge interleave windows, allow for a
x8-endpoint-interleave configuration per memory-type with each device
contributing the minimum 256MB extent. Similarly, for the x1 host-bridge
interleave windows, allow for a x4-endpoint-interleave configuration per
memory-type.
Bump up the number of decoders per-port to support hosting 8 regions.
