+ Define a CXL Fixed Memory Window (CFMW).
+
+ Described in the CXL 2.0 ECN: CEDT CFMWS & QTG _DSM.
+
+ They are regions of Host Physical Addresses (HPA) on a system which
+ may be interleaved across one or more CXL host bridges. The system
+ software will assign particular devices into these windows and
+ configure the downstream Host-managed Device Memory (HDM) decoders
+ in root ports, switch ports and devices appropriately to meet the
+ interleave requirements before enabling the memory devices.
+
+ ``targets.X=target`` provides the mapping to CXL host bridges
+ which may be identified by the id provied in the -device entry.
+ Multiple entries are needed to specify all the targets when
+ the fixed memory window represents interleaved memory. X is the
+ target index from 0.
+
+ ``size=size`` sets the size of the CFMW. This must be a multiple of
+ 256MiB. The region will be aligned to 256MiB but the location is
+ platform and configuration dependent.
+
+ ``interleave-granularity=granularity`` sets the granularity of
+ interleave. Default 256KiB. Only 256KiB, 512KiB, 1024KiB, 2048KiB
+ 4096KiB, 8192KiB and 16384KiB granularities supported.
+
+ Example:
+
+ ::
+
+ -machine cxl-fmw.0.targets.0=cxl.0,cxl-fmw.0.targets.1=cxl.1,cxl-fmw.0.size=128G,cxl-fmw.0.interleave-granularity=512k
