Profiling QEMU during Fedora 35 for PPC64 boot revealed that
6.39% of total time was being spent in helper_insns_inc(), on a
POWER9 machine. To avoid calling this helper every time PMCs had
to be incremented, an inline implementation of PMC5 increment and
check for overflow was developed. This led to a reduction of
about 12% in Fedora's boot time.

Add 2 new PMC related HFLAGS:
- HFLAGS_PMCJCE - value of MMCR0 PMCjCE bit
- HFLAGS_PMC_OTHER - set if a PMC other than PMC5-6 is enabled
These flags allow further optimization of PMC5 update code, by
allowing frequently tested conditions to be performed at
translation time.

The significant difference in performance when REPT is low and LOOP is
high I think is due to the fact that the new implementation has a higher
translation time, as when using a helper only 5 TCGop are used but with
the patch a total of 10 TCGop are needed (Power lacks a direct mul_vec
equivalent so this instruction is implemented with the help of 5 others,
vmuleu, vmulou, vmrgh, vmrgl and vpkum).

ISA v2.06 adds new variations of wait, specified by the WC field. These
are not all compatible with the prior wait implementation, because they
add additional conditions that cause the processor to resume, which can
cause software to hang or run very slowly.
At this moment, with the current wait implementation and a pseries guest
using mainline kernel with new wait upcodes [1], QEMU hangs during boot if
more than one CPU is present:
qemu-system-ppc64 -M pseries,x-vof=on -cpu POWER10 -smp 2 -nographic
-kernel zImage.pseries -no-reboot
QEMU will exit (as there's no filesystem) if the test "passes", or hang
during boot if it hits the bug.
ISA v3.0 changed the wait opcode and removed the new variants (retaining
the WC field but making non-zero values reserved).
ISA v3.1 added new WC values to the new wait opcode, and added a PL
field.
This patch implements the new wait encoding and supports WC variants
with no-op implementations, which provides basic correctness as
explained in comments.

Initial intent for the spr_tcg header was to expose the spr_read|write
callbacks that are only used by TCG code. However, although these
routines are TCG-specific, the KVM code needs access to env->sprs
which creation is currently coupled to the callback registration.
We are probably not going to decouple SPR creation and TCG callback
registration any time soon, so let's rename the header to spr_common
to accomodate the register_*_sprs functions that will be moved out of
cpu_init.c in the following patches.

An Event-Based Branch (EBB) allows applications to change the NIA when a
event-based exception occurs. Event-based exceptions are enabled by
setting the Branch Event Status and Control Register (BESCR). If the
event-based exception is enabled when the exception occurs, an EBB
happens.
The following operations happens during an EBB:
- Global Enable (GE) bit of BESCR is set to 0;
- bits 0-61 of the Event-Based Branch Return Register (EBBRR) are set
to the the effective address of the NIA that would have executed if the EBB
didn't happen;
- Instruction fetch and execution will continue in the effective address
contained in the Event-Based Branch Handler Register (EBBHR).
The EBB Handler will process the event and then execute the Return From
Event-Based Branch (rfebb) instruction. rfebb sets BESCR_GE and then
redirects execution to the address pointed in EBBRR. This process is
described in the PowerISA v3.1, Book II, Chapter 6 [1].
This patch implements the rfebb instruction. Descriptions of all
relevant BESCR bits are also added - this patch is only using BESCR_GE,
but the next patches will use the remaining bits.

PM_RUN_INST_CMPL, instructions completed with the run latch set, is
the architected PowerISA v3.1 event defined with PMC4SEL = 0xFA.
Implement it by checking for the CTRL RUN bit before incrementing the

translation block each time SPR_CTRL is written. A small tweak in
pmu_increment_insns() is then needed to only increment this event
if the thread has the run latch.

The PMU is already counting cycles by calculating time elapsed in
nanoseconds. Counting instructions is a different matter and requires
another approach.
This patch adds the capability of counting completed instructions (Perf
event PM_INST_CMPL) by counting the amount of instructions translated in
each translation block right before exiting it.
A new pmu_count_insns() helper in translation.c was added to do that.
After verifying that the PMU is counting instructions, call
helper_insns_inc(). This new helper from power8-pmu.c will add the
instructions to the relevant counters. It'll also be responsible for
triggering counter negative overflows as it is already being done with
cycles.
To verify whether the PMU is counting instructions or now, a new hflags
named 'HFLAGS_INSN_CNT' is introduced. This flag will match the internal
state of the PMU. We're be using this flag to avoid calling
helper_insn_inc() when we do not have a valid instruction event being
sampled.

(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.
