Peter Maydell 4f2eff36ad hw/intc/armv7m_nvic: Fix ICSR PENDNMISET/CLR handling
The PENDNMISET/CLR bits in the ICSR should be RAZ/WI from
NonSecure state if the AIRCR.BFHFNMINS bit is zero. We had
misimplemented this as making the bits RAZ/WI from both
Secure and NonSecure states. Fix this bug by checking
attrs.secure so that Secure code can pend and unpend NMIs.

Peter Maydell 5a53e2c1dc hw/intc/armv7m_nvic: Don't hardcode M profile ID registers in NVIC
Instead of hardcoding the values of M profile ID registers in the
NVIC, use the fields in the CPU struct. This will allow us to
give different M profile CPU types different ID register values.

This commit includes the addition of the missing ID_ISAR5,
which exists as RES0 in both v7M and v8M.

(The values of the ID registers might be wrong for the M4 --
this commit leaves the behaviour there unchanged.)

Marcel Apfelbaum fc67208f22 hw/pci-bridge: fix pcie root port's IO hints capability
The gen_pcie_root_port mem-reserve and pref32-reserve properties are
defined as size (so uint64_t), but passed as uint32_t when building
the 'IO hints' vendor specific capability.
Passing 4G (or more) gets truncated and passed as a zero reservation.
Is not a huge issue since the guest firmware will always compare the
hints with the default value and take the maximum.

Fix it by passing the values as uint64_t and failing to init the
gen_pcie_root_port id invalid values are used.

Define two functions to update the interrupt state, and call them
on loadvm.  This removes the need to migrate the state as part of

Pavel Pisa d18957dbcc net/can: simple messages transport implementation for QEMU
The CanBusState state structure is created for each
emulated CAN channel. Individual clients/emulated
CAN interfaces or host interface connection registers
to the bus by CanBusClientState structure.

The CAN core is prepared to support connection to the
real host CAN bus network. The commit with such support
for Linux SocketCAN follows.

Implementation is as simple as possible.  There is no state to be
migrated, and messages prioritization and queuing are not considered
for now.  But it is intended to be extended when need arises.

Mark Cave-Ayland 51f233ec92 misc: introduce new mos6522 VIA device and enable it for ppc builds
The MOS6522 VIA forms the bridge part of several Mac devices, including the
Mac via-cuda and via-pmu devices. Introduce a standard mos6522 device that
can be shared amongst multiple implementations.

This is effectively taking the 6522 parts out of cuda.c and turning them
into a separate device whilst also applying some style tidy-ups and including
a conversion to trace-events.

Mark Cave-Ayland ce19480e91 cuda: factor out timebase-derived counter value and load time
Commit b981289c49 "PPC: Cuda: Use cuda timer to expose tbfreq to guest" altered
the timer calculations from those based upon the hardware CUDA clock frequency
to those based upon the CPU timebase frequency.

In fact we can isolate the differences to 2 simple changes: one to the counter
read value and another to the counter load time. Move these changes into
separate functions so the implementation can be swapped later.

Mark Cave-Ayland a797ec500a cuda: set timer 1 frequency property to CUDA_TIMER_FREQ
Now that we have successfully decoupled the timebase frequency and the hardware
timer frequency, set the timer 1 frequency property to CUDA_TIMER_FREQ and alter
get_next_irq_time() to use it rather than the hard-coded constant.

In addition to this we must now switch the tb_diff calculation over to use the
timebase frequency now that the hardware clock frequency and the timebase
frequency are different.
