If the HCR_EL2.IMO or FMO bits are set, accesses to ICC_
system registers are redirected to be accesses to ICV_
registers (the guest-visible interface to the virtual
interrupt controller). Implement this behaviour for the
ICV_ registers which are simple accessors to the underlying

The GICv3 virtualization interface includes system registers
accessible only to the hypervisor which form the control
interface for interrupt virtualization. Implement these
registers.
The function gicv3_cpuif_virt_update() which determines
whether it needs to signal vIRQ, vFIQ or a maintenance
interrupt is introduced here as a stub function -- its
implementation will be added in a subsequent commit.

As the first step in adding support for the virtualization
extensions to the GICv3 emulation:
* add the necessary data fields to the state structures
* add the fields to the migration state, as a subsection
which is only present if virtualization is enabled
The use of a subsection means we retain migration
compatibility as EL2 is not enabled on any CPUs currently.

Using -cpu cortex-a9 (or any other unsupported CPU) with the virt

in commit 9ac4ef77, which incorrectly added a NULL terminator when
converting the VirtBoardInfo array into a simple array of strings

a termination condition based on ARRAY_SIZE, so the NULL is
spurious and causes the strcmp() to segfault if we reach it.

The dp8393x has several 32-bit values which are formed by concatenating

with ((s->reg[HI] << 16) | s->reg[LO]) can result in an unintended
sign extension because "x << 16" is of type 'int' even though s->reg
is unsigned, and so if the expression is used in a context where
it is cast to uint64_t the value is incorrectly sign-extended.
Fix this by using accessor functions with a uint32_t return type;
this also makes the code a bit easier to read.
This should fix Coverity issues 1307765, 1307766, 1307767, 1307768.

versions already depend on HW_COMPAT_2_8 (see commit e353aac51b).
Therefore adding the "x-file-slots" compat values to HW_COMPAT_2_8

kernel booting, is also not versioned.

We'd like to raise the value of FW_CFG_FILE_SLOTS. Doing it naively could
lead to problems with backward migration: a more recent QEMU (running an
older machine type) would allow the guest, in fw_cfg_select(), to select a
high key value that is unavailable in the same machine type implemented by
the older (target) QEMU. On the target host, fw_cfg_data_read() for
example could dereference nonexistent entries.
As first step, size the FWCfgState.entries[*] and FWCfgState.entry_order
arrays dynamically. All three array sizes will be influenced by the new
field FWCfgState.file_slots (and matching device property).
Make the following changes:
- Replace the FW_CFG_FILE_SLOTS macro with FW_CFG_FILE_SLOTS_MIN (minimum
count of fw_cfg file slots) in the header file. The value remains 0x10.
- Replace all uses of FW_CFG_FILE_SLOTS with a helper function called
fw_cfg_file_slots(), returning the new property.
- Eliminate the macro FW_CFG_MAX_ENTRY, and replace all its uses with a
helper function called fw_cfg_max_entry().
- In the MMIO- and IO-mapped realize functions both, allocate all three
arrays dynamically, based on the new property.
- The new property defaults to FW_CFG_FILE_SLOTS_MIN. This is going to be
customized in the following patches.
