target/ppc/kvm.c calls out to code in hw/ppc/spapr*.c; that code is
not present and fails to link if CONFIG_PSERIES is not enabled.
Adjust kvm.c to depend on CONFIG_PSERIES instead of TARGET_PPC64,
and compile out anything that requires cap_papr, because only
the pseries machine will call kvmppc_set_papr().

Printing a "PowerPC" in front of each CPU name is not helpful at all:
It is confusing for the users since they don't know whether they
have to specify these letters for the "-cpu" parameter, too, and
it also takes some precious space in the dense output of the CPU
entries. Let's simply remove this now and use two spaces at the
beginning of the lines for the indentation of the entries instead,
and add a "Available CPUs" in the very first line, like most other
target architectures are doing it for their CPU help output already.

Hardware clears the MSR[ME] bit when delivering a machine check
interrupt, so that is what QEMU does.
The spapr environment runs in supervisor mode though, and receives
machine check interrupts after they are processed by the hypervisor,
and MSR[ME] must always be enabled in supervisor mode (otherwise it
could checkstop the system). So MSR[ME] must not be cleared when
delivering machine checks to the supervisor.
The fix to prevent supervisor mode from modifying MSR[ME] also
prevented it from re-enabling the incorrectly cleared MSR[ME] bit
when returning from handling the interrupt. Before that fix, the
problem was not very noticable with well-behaved code. So the
Fixes tag is not strictly correct, but practically they go together.
Found by kvm-unit-tests machine check tests (not yet upstream).

The GDB server protocol assigns an arbitrary numbering of the SPRs.
We track this correspondence on each SPR with gdb_id, using it to
resolve any SPR requests GDB makes.
Early on we generate an XML representation of the SPRs to give GDB,
including this numbering. However the XML is cached globally, and we
skip setting the SPR gdb_id values on subsequent threads if we detect
it is cached. This causes QEMU to fail to resolve SPR requests against
secondary CPUs because it cannot find the matching gdb_id value on that
thread's SPRs.
This is a minimal fix to first assign the gdb_id values, then return
early if the XML is cached. Otherwise we generate the XML using the
now already initialised gdb_id values.

translations, so there is nothing to flush. The exception is multiple
software TLBs that cover the same address and address space, but that is

does not give an obviously better outcome in that case either.

The 440 tlbwe (write entry) instruction misses several cases that must
flush the TCG TLB:
- If the new size is smaller than the existing size, the EA no longer
covered should be flushed. This looks like an inverted inequality
test.
- If the TLB PID changes.
- If the TLB attr bit 0 (translation address space) changes.
- If low prot (access control) bits change.
Fix this by removing tricks to avoid TLB flushes, and just invalidate
the TLB if any valid entry is being changed, similarly to 4xx.
Optimisations will be introduced in subsequent changes.

This implements the core timebase state machine, which is the core side
of the time-of-day system in POWER processors. This facility is operated
by control fields in the TFMR register, which also contains status
fields.
The core timebase interacts with the chiptod hardware, primarily to
receive TOD updates, to synchronise timebase with other cores. This
model does not actually update TB values with TOD or updates received
from the chiptod, as timebases are always synchronised. It does step
through the states required to perform the update.
There are several asynchronous state transitions. These are modelled
using using mfTFMR to drive state changes, because it is expected that
firmware poll the register to wait for those states. This is good enough
to test basic firmware behaviour without adding real timers. The values
chosen are arbitrary.

One of the functions of the ChipTOD is to transfer TOD to the Core
(aka PC - Pervasive Core) timebase facility.
The ChipTOD can be programmed with a target address to send the TOD
value to. The hardware implementation seems to perform this by
sending the TOD value to a SCOM address.
This implementation grabs the core directly and manipulates the
timebase facility state in the core. This is a hack, but it works
enough for now. A better implementation would implement the transfer
to the PnvCore xscom register and drive the timebase state machine
from there.

The ISA changed around v2.03 to bring TB and TBU reads into the SPR

but will be phased out). Later, VTB was added which is an entirely

From the earliest PowerPC ISA, TBR (later SPR) 268 has been called TB
and accessed with mftb instruction. The problem is that TB is the name
of the 64-bit register, and 32-bit implementations can only read the
lower half with one instruction, so 268 has also been called TBL and
it does only read TBL on 32-bit.
