This patch starts an IBM Power8+ compatible PMU implementation by adding
the representation of PMU events that we are going to sample,
PMUEventType. This enum represents a Perf event that is being sampled by
a specific counter 'sprn'. Events that aren't available (i.e. no event
was set in MMCR1) will be of type 'PMU_EVENT_INVALID'. Events that are
inactive due to frozen counter bits state are of type
'PMU_EVENT_INACTIVE'. Other types added in this patch are
PMU_EVENT_CYCLES and PMU_EVENT_INSTRUCTIONS. More types will be added
later on.
Let's also add the required PMU cycle overflow timers. They will be used
to trigger cycle overflows when cycle events are being sampled. This
timer will call cpu_ppc_pmu_timer_cb(), which in turn calls
fire_PMC_interrupt(). Both functions are stubs that will be implemented
later on when EBB support is added.
Two new helper files are created to host this new logic.
cpu_ppc_pmu_init() will init all overflow timers during CPU init time.

We should not have TCG code in powerpc_excp because some kvm-only
routines use it indirectly to dispatch interrupts. See
kvm_handle_debug, spapr_mce_req_event and
spapr_do_system_reset_on_cpu.
We can re-introduce the change once we have split the interrupt
injection code between KVM and TCG.

When Altivec support was added to the e6500 kernel in 2012[1], the
QEMU code was not changed, so we don't register the VPU/VPUA
exceptions for the e6500:
qemu: fatal: Raised an exception without defined vector 73
Note that the error message says 73, instead of 32, which is the IVOR
for VPU. This is because QEMU knows only knows about the VPU interrupt
for the 7400s. In theory, we should not be raising _that_ VPU
interrupt, but instead another one specific for the e6500.
We unfortunately cannot register e6500-specific VPU/VPUA interrupts
because the SPEU/EFPDI interrupts also use IVOR32/33. These are
present only in the e500v1/2 versions. From the user manual:
e500v1, e500v2: only SPEU/EFPDI/EFPRI
e500mc, e5500: no SPEU/EFPDI/EFPRI/VPU/VPUA
e6500: only VPU/VPUA
So I'm leaving IVOR32/33 as SPEU/EFPDI, but altering the dispatch code
to convert the VPU #73 to a #32 when we're in the e6500. Since the
handling for SPEU and VPU is the same this is the only change that's
needed. The EFPDI is not implemented and will cause an abort. I don't
think it worth it changing the error message to take VPUA into
consideration, so I'm not changing anything there.

because the instructions are using GEN_VSX_HELPER_R3, which adds 32

QEMU installs a custom U-Boot in-memory descriptor to share board
information with Linux, which means that the QEMU machine was
initially designed to support booting Linux directly without using the
loaded FW. But, it's not that simple because the CPU still starts at
address 0xfffffffc where nothing is currently mapped. Support must
have been broken these last years.
Since we can not find a "ppc405_rom.bin" firmware file, request one to
be specified on the command line. A consequence of this change is that
the machine can be booted directly from Linux without any FW being
loaded. This is still broken and the CPU start address will be fixed
in the next changes.

The PPC 405 CPU is a system-on-a-chip, so all 405 machines are very similar,
except for some external periphery. However, the periphery of the 'taihu'
machine is hardly emulated at all (e.g. neither the LCD nor the USB part had
been implemented), so there is not much value added by this board. The users
can use the 'ref405ep' machine to test their PPC405 code instead.

"fdt_addr_r=1800000\0"
"ramdisk_addr_r=1900000\0"
The taihu is one of these boards, the ref405ep is not but we don't
have much information on it and both boards have a very similar
address space layout.
Also, if loaded at address 0, U-Boot will partially overwrite the
uImage because of a bug in get_ram_size() (U-Boot v2015.10) not
restoring properly the probed RAM contents and because the exception
vectors are installed in the same range. Finally, a gzipped kernel
image will be uncompressed at 0x0. These are all good reasons for not
mappping a kernel image at this address.
Change the kernel load address to match U-Boot expectations and fix

(Applies to 7441, 7445, 7450, 7451, 7455, 7457, 7447, 7447a and 7448)
The QEMU-side software TLB implementation for the 7450 family of CPUs
is being removed due to lack of known users in the real world. The
last users in the code were removed by the two previous commits.
A brief history:
The feature was added in QEMU by commit 7dbe11acd8 ("Handle all MMU
models in switches...") with the mention that Linux was not able to
handle the TLB miss interrupts and the MMU model would be kept
disabled.
At some point later, commit 8ca3f6c382 ("Allow selection of all
defined PowerPC 74xx (aka G4) CPUs.") enabled the model for the 7450
family without further justification.
We have since the year 2011 [1] been unable to run OpenBIOS in the
7450s and have not heard of any other software that is used with those
CPUs in QEMU. Attempts were made to find a guest OS that implemented
the TLB miss handlers and none were found among Linux 5.15, FreeBSD 13,
MacOS9, MacOSX and MorphOS 3.15.
All CPUs that registered this feature were moved to an MMU model that
replaces the software TLB with a QEMU hardware TLB
implementation. They can now run the same software as the 7400 CPUs,
including the OSes mentioned above.

The e600 CPU is a successor of the 7448 and like all the 7450s CPUs,
it has an optional software TLB feature.
We have determined that there is no OS software support for the 7450
software TLB available these days. See the previous commit for more
information.
This patch disables the SPRs and instructions related to software TLB
from the e600 CPU.
No functional change intended. These facilities should be used by the
OS in interrupt handlers for interrupts that QEMU never generates.

(Applies to 7441, 7445, 7450, 7451, 7455, 7457, 7447 and 7447a)*
We have since 2011 [1] been unable to run OpenBIOS in the 7450s and
have not heard of any other software that is used with those CPUs in
QEMU. A current discussion [2] shows that the 7450 software TLB is
unsupported in Linux 5.15, FreeBSD 13, MacOS9, MacOSX and MorphOS
3.15. With no known support in firmware or OS, this means that no code
for any of the 7450 CPUs is ever ran in QEMU.
Since the implementation in QEMU of the 7400 MMU is the same as the
7450, except for the software TLB vs. hardware TLB search, this patch
changes all 7450 cpus to the 7400 MMU model. This has the practical
effect of disabling the software TLB feature while keeping other
aspects of address translation working as expected.
This allow us to run software on the 7450 family again.
*- note that the 7448 is currently aliased in QEMU for a 7400, so it
is unaffected by this change.

separate float{32,64}_maddsub_update_excp functions with a
single float_invalid_op_madd function.
Fix VSX_MADD by passing sfprf to float_invalid_op_madd,
whereas the previous *_maddsub_update_excp assumed it true.

In GEN_FLOAT_B, we called helper_reset_fpstatus immediately
before calling helper_fri*. Therefore get_float_exception_flags
is known to be zero, and this code can be simplified.

This is the proper type for the enumeration.

There's no reason the callers can't tail call to one function.
Leave it up to the compiler either way.

We were returning nanval for any instance of invalid being set,
but that is an incorrect for VXCVI. This failure can be seen
in the float_convs tests.
