40cb501a2f mem: format address in hex in the memory controller debug trace
Before it was using the decimal format contrary to
everywhere else in gem5.
This was making it difficult to follow an address in the trace
once going to main memory.

c05e086814 python,scons: Only generate pybind if using python
This reimplements the previously reverted change: Always generate default
create() methods.

The pybind code should only be generated when python is enabled. This
change passes whether python is enabled into the SimObject code creation
method. Then, the params code is optionally included.

Note: Due to some problems in GCC's linker (or something else...) we
need to have a single file with all of the generated code for the
SimObject.

8c48ba9207 arch-riscv: update all pmp rules on pmp addr update
Update in a pmp addr register can have effect on other
pmp rules, for example if TOR mode is used.
According to specs, update in a pmp entry is made using
an update to a pmpaddr reg, followed by an update to pmpcfg
reg which should be followed by sfence.vma. Currently,
in gem5 update in cfg register (combination of 8 pmpcfg
regs.), which should happen after a pmpaddr reg. update,
leads to an update in all pmp rules. However, there seems to
be a case where we receive an interrupt right before execution
of an instruction to update cfg register, which leads to unindented
side-effects of S mode addresses falsely falling into a wrong
pmp region. Updating pmp rules right after pmpaddr update, might
be redundant, but should not break anything otherwise.

e7a941ee08 tests: Re-enable the realview-o3-checker test
We are using the VExpress_GEM5_V1 platform for this test.
This is currently needed as the checker is GICv3 incompatible:

When validating MiscReg cpu interface register (MISCREG_ICC_*) updates
the underlying ISA storage is checked. However the content of some of
those registers is hardcoded in the GICv3 logic

23366a2899 cpu: Dispatch PCEvents to the CheckerCPU SimpleThread
Moving PCEvents scheduling from the system to the Thread [1]
requires us to forward PCEvents to the CheckerCPU thread.

We will otherwise encounter a divergence with the checker when trying to
emulate a SkipFunction in the host (e.g. udelay on Arm).
While the original thread will correctly emulate it and jump to the next
instruction in the binary), the Checker's thread, with no scheduled
PCEvent, will jump straight into the function.

This is fixing realview64-o3-checker.py regression

499a1cc7e8 base-stats,mem: Fix empty Stats::Info names
Sub-groups should not contain empty names. To make sure
that is the case, generate tokens even if the string is
empty.

Before the name 'group1..group2' would generate 2 tokens:
'group1' and 'group2'. As such, validateStatName would
not be able to detect it was an invalid name. With this
change three tokens will be generated: 'group1', '',
and 'group2'. The empty string will then trigger the
item->empty() check, which will successfully inform that
such stat name is not valid.

SLICC was breaking this rule with one of its stats by
creating a sub-group (inTransLatHist) whose parent had
an empty name, so it has been fixed.

18de63cea0 sim: Remove (UN)SERIALIZE_OBJ_PTR
SimObjects keep a static list with all existing
SimObjects. This list is then used to serialize
all objects declared in the system. If these
macros were used then an object would be serialized
more than once, which is not a correct behavior.

19c7429520 sim,util: Remove event dependencies from serialize.hh
With this change serialize.hh is no longer responsible
for the (un)serialization of events. As a general rule,
rules to (un)serialize non-basic types should be defined
at the file that introduces that type. Therefore,
(UN)SERIALIZE_EVENT have been moved to eventq.hh.

Globals has a single instance which must be serialized
and unserialized. Instead of having a stray global
variable handled by Serialization, we pass its management
to Root. As a side effect, Globals is assigned its own
files: sim/globals.(cc/hh).

Finally, 'unserializeGlobals()' is removed, so that
Root can fully handle Globals' serialization. This
breaks checkpoint compatibility, so a checkpoint
upgrader is added.

c493d2c4ad sim,mem-ruby: Handle interleaved device memory
Device memories are used for PCI devices which have their own pools of
backing store memory such as amdgpu device. The check for an address
being in device memory previously did not handle multiple interleaved
memory devices with the same address range. Therefore, the device memory
check would fail if the interleaving masks did not match. This updates
the method to iterate through all device memories that handle the
RequestorID and returns true if any of the device memories contain the
packet address.

e9bac9df87 dev-amdgpu,configs: checkpoint before MMIOs
The flow for Full System amdgpu is the use KVM to boot linux and begin
loading the driver module. However, the amdgpu module requires reading
the VGA ROM located at 0xc0000 in X86. KVM does not support having a
small 128KiB hole at this location, therefore we take a checkpoint and
switch to a timing CPU to continue loading the drivers before the VGA
ROM is read.

This creates a checkpoint just before the first MMIOs. This is indicated
by three interrupts being sent to the PCI device. After three interrupts
in a row are counted a checkpoint exit event occurs. The interrupt
counter is reset if a non-interrupt PCI read is seen.

182ef827c8 cpu: Implement basic HTM capabilities in the CheckerCPU
The O3CPU, which supports transactional memory (HTM), is using
the inHtmTransactionalState and getHtmCheckpointPtr methods
to check if we are in the middle of a transaction and return
false or a nullptr if that's not the case.

We need to avoid aborting simulation (panic) when those methods are
called in the O3CPU + Checker simulation.

This patch is providing the minimal support to re-enable O3 + Checker
runs and it is not providing HTM support in the CheckerCPU (meaning, we
won't be able to use the Checker in a transactional simulation)
