3a7f009abc Implement missing parts of the logic for the POWER PURR
The PURR (Processor Utilization Resource Register) is a register found
on recent POWER CPUs.  The guts of implementing it at least enough to
get by are already present in qemu, however some of the helper
functions needed to actually wire it up are missing.

This patch adds the necessary glue, so that the PURR can be wired up
when we implement newer POWER CPU targets which include it.

efdef95fee Implement PowerPC slbmfee and slbmfev instructions
For a 64-bit PowerPC target, qemu correctly implements translation
through the segment lookaside buffer.  Likewise it supports the
slbmte instruction which is used to load entries into the SLB.

However, it does not emulate the slbmfee and slbmfev instructions
which read SLB entries back into registers.  Because these are
only occasionally used in guests (mostly for debugging) we get
away with it.

However, given the recent SLB cleanups, it becomes quite easy to
implement these, and thereby allow, amongst other things, a guest
Linux to use xmon's command to dump the SLB.

d569956eaf Add a hook to allow hypercalls to be emulated on PowerPC
PowerPC and POWER chips since the POWER4 and 970 have a special
hypervisor mode, and a corresponding form of the system call
instruction which traps to the hypervisor.

qemu currently has stub implementations of hypervisor mode.  That
is, the outline is there to allow qemu to run a PowerPC hypervisor
under emulation.  There are a number of details missing so this
won't actually work at present, but the idea is there.

What there is no provision at all, is for qemu to instead emulate
the hypervisor itself.  That is to have hypercalls trap into qemu
and their result be emulated from qemu, rather than running
hypervisor code within the emulated system.

Hypervisor hardware aware KVM implementations are in the works and
it would  be useful for debugging and development to also allow
full emulation of the same para-virtualized guests as such a KVM.

Therefore, this patch adds a hook which will allow a machine to
set up emulation of hypervisor calls.

81762d6dd0 Clean up PowerPC SLB handling code
Currently the SLB information when emulating a PowerPC 970 is
storeed in a structure with the unhelpfully named fields 'tmp'
and 'tmp64'.  While the layout in these fields does match the
description of the SLB in the architecture document, it is not
convenient either for looking up the SLB, or for emulating the
slbmte instruction.

This patch, therefore, reorganizes the SLB entry structure to be
divided in the the "ESID related" and "VSID related" fields as
they are divided in instructions accessing the SLB.

In addition to making the code smaller and more readable, this will
make it easier to implement for the 1TB segments used in more
recent PowerPC chips.

7447545544 change all other clock references to use nanosecond resolution accessors
This was done with:

    sed -i 's/qemu_get_clock\>/qemu_get_clock_ns/' \
        $(git grep -l 'qemu_get_clock\>' )
    sed -i 's/qemu_new_timer\>/qemu_new_timer_ns/' \
        $(git grep -l 'qemu_new_timer\>' )

after checking that get_clock and new_timer never occur twice
on the same line.  There were no missed occurrences; however, even
if there had been, they would have been caught by the compiler.

There was exactly one false positive in qemu_run_timers:

     -    current_time = qemu_get_clock (clock);
     +    current_time = qemu_get_clock_ns (clock);

which is of course not in this patch.

fc87e18530 KVM: PPC: Add level based interrupt logic
KVM on PowerPC used to have completely broken interrupt logic. Usually,
interrupts work by having a PIC that pulls a line up/down, so the CPU knows
that an interrupt is active. This line stays active until some action is
done to the PIC to release the line.

On KVM for PPC, we just checked if there was an interrupt pending and pulled
a line in the kernel module. We never released it though, hoping that kernel
space would just declare an interrupt as released when injected - which is
wrong.

To fix this, we need to completely redesign the interrupt injection logic.
Whenever an interrupt line gets triggered, we need to notify kernel space
that the line is up. Whenever it gets released, we do the same. This way
we can assure that the interrupt state is always known to kernel space.

This fixes random stalls in KVM guests on PowerPC that were waiting for
an interrupt while everyone else thought they received it already.

2bece2c883 tcg: Optionally sign-extend 32-bit arguments for 64-bit hosts.
Some hosts (amd64, ia64) have an ABI that ignores the high bits
of the 64-bit register when passing 32-bit arguments.  Others
require the value to be properly sign-extended for the type.
I.e. "int32_t" must be sign-extended and "uint32_t" must be
zero-extended to 64-bits.

To effect this, extend the "sizemask" parameter to tcg_gen_callN
to include the signedness of the type of each parameter.  If the
tcg target requires it, extend each 32-bit argument into a 64-bit
temp and pass that to the function call.

This ABI feature is required by sparc64, ppc64 and s390x.

c3d420ead1 target-ppc: fix RFI by clearing some bits of MSR
Since commit 2ada0ed, "Return From Interrupt" is broken for PPC processors
because some interrupt specifics bits of SRR1 are copied to MSR.

SRR1 is a save of MSR during interrupt.
During RFI, MSR must be restored from SRR1.
But some bits of SRR1 are interrupt-specific and are not used for MSR saving.

This is the specification (ISA 2.06) at chapter 6.4.3 (Interrupt Processing):
"2. Bits 33:36 and 42:47 of SRR1 or HSRR1 are loaded with information specific
    to the interrupt type.
 3. Bits 0:32, 37:41, and 48:63 of SRR1 or HSRR1 are loaded with a copy of the
    corresponding bits of the MSR."

Below is a representation of MSR bits which are not saved:
0:15 16:31 32  33:36    37:41      42:47     48:63
——— | ——— | — X X X X — — — — — X X X X X X | ————
0000 0000 |    7   |   8   |   3   |   F    | 0000

History:
In the initial Qemu implementation (e1833e1), the mask 0x783F0000 was used for
saving MSR in SRR1. But all the bits 32:47 were cleared during RFI restoring.
This was wrong. The commit 2ada0ed explains that this breaks Altivec.
Indeed, bit 38 (for Altivec support) must be saved and restored.
The change of 2ada0ed was to restore all the bits of SRR1 to MSR.
But it's also wrong.

Explanation:
As an example, let's see what's happening after a TLB miss.
According to the e300 manual (E300CORERM table 5-6), the TLB miss interrupts
set the bits 44-47 for KEY, I/D, WAY and S/L. These bits are specifics to the
interrupt and must not be copied into MSR at the end of the interrupt.
With the current implementation, a TLB miss overwrite bits POW, TGPR and ILE.

Fix:
It shouldn't be needed to filter-out bits on MSR saving when interrupt occurs.
Specific bits overwrite MSR ones in SRR1.
But at the end of interrupt (RFI), specifics bits must be cleared before
restoring MSR from SRR1. The mask 0x783F0000 apply here.

Discussion:
The bits of the mask 0x783F0000 are cleared after an interrupt.
I cannot find a specification which talks about this
but I assume it is the truth since Linux can run this way.
Maybe it's not perfect but it's better (works for e300).

c821c2bd4f PPC/KVM: make iothread work
When running with --enable-io-thread the timer we have doesn't help,
because it doesn't wake up the CPU thread. So instead we need to
actually kick it.

While at it I refined the logic a bit to not dumbly trigger a timer
every 500ms, but rather do it more often after an interrupt got injected.
If there's no level based interrupt to be expected, we don't need the
timer anyways.

This makes qemu-system-ppc with --enable-io-thread work when using KVM.

d4c430a80f Large page TLB flush
QEMU uses a fixed page size for the CPU TLB.  If the guest uses large
pages then we effectively split these into multiple smaller pages, and
populate the corresponding TLB entries on demand.

When the guest invalidates the TLB by virtual address we must invalidate
all entries covered by the large page.  However the address used to
invalidate the entry may not be present in the QEMU TLB, so we do not
know which regions to clear.

Implementing a full vaiable size TLB is hard and slow, so just keep a
simple address/mask pair to record which addresses may have been mapped by
large pages.  If the guest invalidates this region then flush the
whole TLB.

ea375f9ab8 KVM: Rework VCPU state writeback API
This grand cleanup drops all reset and vmsave/load related
synchronization points in favor of four(!) generic hooks:

- cpu_synchronize_all_states in qemu_savevm_state_complete
  (initial sync from kernel before vmsave)
- cpu_synchronize_all_post_init in qemu_loadvm_state
  (writeback after vmload)
- cpu_synchronize_all_post_init in main after machine init
- cpu_synchronize_all_post_reset in qemu_system_reset
  (writeback after system reset)

These writeback points + the existing one of VCPU exec after
cpu_synchronize_state map on three levels of writeback:

- KVM_PUT_RUNTIME_STATE (during runtime, other VCPUs continue to run)
- KVM_PUT_RESET_STATE   (on synchronous system reset, all VCPUs stopped)
- KVM_PUT_FULL_STATE    (on init or vmload, all VCPUs stopped as well)

This level is passed to the arch-specific VCPU state writing function
that will decide which concrete substates need to be written. That way,
no writer of load, save or reset functions that interact with in-kernel
KVM states will ever have to worry about synchronization again. That
also means that a lot of reasons for races, segfaults and deadlocks are
eliminated.

cpu_synchronize_state remains untouched, just as Anthony suggested. We
continue to need it before reading or writing of VCPU states that are
also tracked by in-kernel KVM subsystems.

Consequently, this patch removes many cpu_synchronize_state calls that
are now redundant, just like remaining explicit register syncs.

For some odd reason we sometimes hang inside KVM forever. I'd guess it's
a race condition where we actually have a level triggered interrupt, but
the infrastructure can't expose that yet, so the guest ACKs it, goes to
sleep and never gets notified that there's still an interrupt pending.

As a quick workaround, let's just wake up every 500 ms. That way we can
assure that we're always reinjecting interrupts in time.

dc333cd609 PPC: tell the guest about the time base frequency
Our guest systems need to know by how much the timebase increases every second,
so there usually is a "timebase-frequency" property in the cpu leaf of the
device tree.

This property is missing in OpenBIOS.

With qemu, Linux's fallback timebase speed and qemu's internal timebase speed
match up. With KVM, that is no longer true. The guest is running at the same
timebase speed as the host.

This leads to massive timing problems. On my test machine, a "sleep 2" takes
about 14 seconds with KVM enabled.

This patch exports the timebase frequency to OpenBIOS, so it can then put them
into the device tree.

f407823616 target-ppc: enable PPC_MFTB for 44x
According to PPC440 user manual, PPC 440 supports ``mftb'' even it's a
preserved instruction:

PPC440_UM2013.pdf, p.445, table A-3

when I compile a kernel (2.6.30, bamboo_defconfig/440EP &
canyonlands/460EX), I can see ``mftb'' by using ppc-xxx-objdump
vmlinux

I have also checked the ppc 440x[456], 460S, 464, they also should support mftb.

The following patch enable mftb for all ppc 440 variants, including:
440EP, 440GP, 440x4, 440x5 and 460

33890b3e0d target-ppc: fix evmergelo and evmergelohi
For 32-bit PPC targets, we translated:

evmergelo rX, rX, rY

as:

rX-lo = rY-lo
rX-hi = rX-lo

which is wrong, because we should be transferring rX-lo first.  This
problem is fixed by swapping the order in which we write the parts of
rX.

Similarly, we translated:

evmergelohi rX, rX, rY

as:

rX-lo = rY-hi
rX-hi = rX-lo

In this case, we can't swap the assignment statements, because that
would just cause problems for:

evmergelohi rX, rY, rX

Instead, we detect the first case and save rX-lo in a temporary
variable:

tmp = rX-lo
rX-lo = rY-hi
rX-hi = tmp

These problems don't occur on PPC64 targets because we don't split the
SPE registers into hi/lo parts for such targets.

7f70c93716 Make the ELF loader aware of backwards compatibility
Most 64 bit architectures I'm aware of support running 32 bit code
of the same architecture as well.

So x86_64 can run i386 code easily and ppc64 can run ppc code.

Unfortunately, the current checks are pretty strict. So you can only
load e.g. an x86_64 elf binary on qemu-system-x86_64, but no i386 one.

This can get really annoying. I first encountered this issue with
my multiboot patch, where qemu-system-x86_64 was unable to load an
i386 elf binary because the elf loader rejected it.

The same thing happened again on PPC64 now. The firmware we're loading
is a PPC32 elf binary, as it's shared with PPC32. But the platform is
PPC64.

Right now there is a hack for this in the ppc cpu.h definition, that
simply sets the type to PPC32 in system emulation mode. While that
works fine for the firmware, it's no good if you also want to load a
PPC64 kernel with -kernel.

So in order to solve this mess, I figured the easiest way is to make
the elf loader aware of platforms that are backwards compatible. For
now I was only sure that x86_64 does i386 and ppc64 does ppc32, but
maybe there are other combinations too.

This patch is a prerequisite for having a working -kernel option on
PPC64.

f6b868fc58 Implement slbmte
In order to modify SLB entries on recent PPC64 machines, the slbmte
instruction is used.

This patch implements the slbmte instruction and makes the "bridge"
mode code use the slb set functions, so we can move the SLB into
the CPU struct later.

This is required for Linux to run on PPC64.

2adab7d6b5 Implement HIOR
A real 970 CPU starts up with HIOR=0xfff00000 and triggers a reset
exception, basically ending up at IP 0xfff001000.

Later on this HIOR has to be set to 0 by the firmware in order to
enable the OS to handle interrupts on its own.

This patch maps HIOR to exec_prefix, which does the same thing
internally in qemu already.

It replaces the previous patch that changed the 970 initialization
constants, as this is the clean solution to the same problem.

This patch removes useless type information in some calls to
tcg_temp_local_new.  It also removes the parameter from the
macro declaration;  if a target has to use a specific non-default
size then it should use tcg_temp_local_new_{i32,i64}.
