When the region driver fails while allocating HPA space for a
new region it can be because the parent resource, the CXL Window,
has no more available space.
In that case, the debug user sees this message:
cxl_core:alloc_hpa:555: cxl region2: failed to allocate HPA: -34
Expand the message like this:
cxl_core:alloc_hpa:555: cxl region8: HPA allocation error (-34) for size:0x20000000 in CXL Window 0 [mem 0xf010000000-0xf04fffffff flags 0x200]
Now the debug user can examine /proc/iomem and consider actions
like removing other allocations in that space or reducing the
size of their region request.

CXL Memory Device SW Guide [1] rev1.0 2.11.2 provides instruction on how to
calculate latency and bandwidth for CXL memory device. Calculate minimum
bandwidth and total latency for the path from the CXL device to the root
port. The QTG id is retrieved by providing the performance data as input
and calling the root port callback ->get_qos_class(). The retrieved id is
stored with the cxl_port of the CXL device.
For example for a device that is directly attached to a host bus:
Total Latency = Device Latency (from CDAT) + Dev to Host Bus (HB) Link
Latency + Generic Port Latency
Min Bandwidth = Min bandwidth for link bandwidth between HB
and CXL device, device CDAT bandwidth, and Generic Port
Bandwidth
For a device that has a switch in between host bus and CXL device:
Total Latency = Device (CDAT) Latency + Dev to Switch Link Latency +
Switch (CDAT) Latency + Switch to HB Link Latency +
Generic Port Latency
Min Bandwidth = Min bandwidth for link bandwidth between CXL device
to CXL switch, CXL device CDAT bandwidth, CXL switch CDAT
bandwidth, CXL switch to HB bandwidth, and Generic Port
Bandwidth.

CXL spec v3.0 9.17.3 CXL Root Device Specific Methods (_DSM)
Add support to retrieve QTG ID via ACPI _DSM call. The _DSM call requires
an input of an ACPI package with 4 dwords (read latency, write latency,
read bandwidth, write bandwidth). The call returns a package with 1 WORD
that provides the max supported QTG ID and a package that may contain 0 or
more WORDs as the recommended QTG IDs in the recommended order.
Create a cxl_root container for the root cxl_port and provide a callback
->get_qos_class() in order to retrieve the QoS class. For the ACPI case,
the _DSM helper is used to retrieve the QTG ID and returned. A
devm_cxl_add_root() function is added for root port setup and registration
of the cxl_root callback operation(s).

The CDAT table is very similar to ACPI tables when it comes to sub-table
and entry structures. The helper functions can be also used to parse the
CDAT table. Add support to the helper functions to deal with an external
CDAT table, and also handle the endieness since CDAT can be processed by a
BE host. Export a function cdat_table_parse() for CXL driver to parse
a CDAT table.
In order to minimize ACPICA code changes, __force is being utilized to deal
with the case of a big endian (BE) host parsing a CDAT. All CDAT data
structure variables are being force casted to __leX as appropriate.
