hw/s390x/s390-pci-bus.c: Use g_assert_not_reached() in functions taking an ett
The s390-pci-bus.c code, Coverity complains about a possible overflow
because get_table_index() can return -1 if the ett value passed in is
not one of the three permitted ZPCI_ETT_PT, ZPCI_ETT_ST, ZPCI_ETT_RT,
but the caller in table_translate() doesn't check this and instead
uses the return value directly in a calculation of the guest address
to read from.
In fact this case cannot happen, because:
* get_table_index() is called only from table_translate()
* the only caller of table_translate() loops through the ett values
in the order RT, ST, PT until table_translate() returns 0
* table_translate() will return 0 for the error cases and when
translate_iscomplete() returns true
* translate_iscomplete() is always true for ZPCI_ETT_PT
So table_translate() is always called with a valid ett value.
Instead of having the various functions called from table_translate()
return a default or dummy value when the ett argument is out of range,
use g_assert_not_reached() to indicate that this is impossible.

hw/arm/virt: Basic CXL enablement on pci_expander_bridge instances pxb-cxl
Code based on i386/pc enablement.
The memory layout places space for 16 host bridge register regions after
the GIC_REDIST2 in the extended memmap. This is a hole in the current
map so adding them here has no impact on placement of other memory regions
(tested with enough CPUs for GIC_REDIST2 to be in use.)
The high memory map is GiB aligned so the hole is there whatever the
size of memory or device_memory below this point.
The CFMWs are placed above the extended memmap. Note the existing
variable highest_gpa is the highest GPA that has been allocated at
a particular point in setting up the memory map. Whilst this caused
some confusion in review there are existing comments explaining this
so nothing is added.
The cxl_devices_state.host_mr provides a small space in which to place
the individual host bridge register regions for whatever host bridges are
allocated via -device pxb-cxl on the command line. The existing dynamic
sysbus infrastructure is not reused because pxb-cxl is a PCI device not
a sysbus one but these registers are directly in the main memory map,
not the PCI address space.
Only create the CEDT table if cxl=on set for the machine. Default to off.

hw/cxl: Make the CXL fixed memory windows devices.
Previously these somewhat device like structures were tracked using a list
in the CXLState in each machine. This is proving restrictive in a few
cases where we need to iterate through these without being aware of the
machine type. Just make them sysbus devices.
Restrict them to not user created as they need to be visible to early
stages of machine init given effects on the memory map.
This change both simplifies state tracking and enables features needed
for performance optimization and hotness tracking by making it possible
to retrieve the fixed memory window on actions elsewhere in the topology.
In some cases the ordering of the Fixed Memory Windows matters.
For those utility functions provide a GSList sorted by the window index.
This ensures that we get consistency across:
- ordering in the command line
- ordering of the host PA ranges
- ordering of ACPI CEDT structures describing the CFMWS.
Other aspects don't have this constraint. For those direct iteration
of the underlying hash structures is fine.
In the setup path for the memory map in pc_memory_init() split the
operations into two calls. The first, cxl_fmws_set_mmemap(), loops over
fixed memory windows in order and assigns their addresses. The second,
cxl_fmws_update_mmio() actually sets up the mmio for each window.
This is obviously less efficient than a single loop but this split design
is needed to put the logic in two different places in the arm64 support
and it is not a hot enough path to justify an x86 only implementation.

hw/cxl-host: Add an index field to CXLFixedMemoryWindow
To enable these to be found in a fixed order, that order needs to be known.
This will later be used to sort a list of these structures so that address
map and ACPI table entries are predictable.
