Roman Kagan 701189e311 hyperv: factor out arch-independent API into hw/hyperv
A significant part of hyperv.c is not actually tied to x86, and can
be moved to hw/.

This will allow to maintain most of Hyper-V and VMBus
target-independent, and to avoid conflicts with inclusion of
arch-specific headers down the road in VMBus implementation.

Also this stuff can now be opt-out with CONFIG_HYPERV.

Roman Kagan 51f0ac6381 hyperv: make hyperv_vp_index inline
Also make the inverse function, hyperv_find_vcpu, static as it's not
used outside hyperv.c

This paves the way to making hyperv.c built optionally.

Roman Kagan 5116122af7 hyperv: split hyperv-proto.h into x86 and arch-independent parts
Some parts of the Hyper-V hypervisor-guest interface appear to be
target-independent, so move them into a proper header.

Not that Hyper-V ARM64 emulation is around the corner but it seems more
conveninent to have most of Hyper-V and VMBus target-independent, and
allows to avoid conflicts with inclusion of arch-specific headers down
the road in VMBus implementation.

Make sint ack callback accept an opaque pointer, that is stored on

This allows for more convenient interaction with the callback.

Besides, nothing outside hyperv.c should need to know the layout of

Igor Mammedov 8b5e6caf01 call HotplugHandler->plug() as the last step in device realization
When [2] was fixed it was agreed that adding and calling post_plug()
callback after device_reset() was low risk approach to hotfix issue
right before release. So it was merged instead of moving already
existing plug() callback after device_reset() is called which would
be more risky and require all plug() callbacks audit.

Looking at the current plug() callbacks, it doesn't seem that moving
plug() callback after device_reset() is breaking anything, so here
goes agreed upon [3] proper fix which essentially reverts [1][2]
and moves plug() callback after device_reset().
This way devices always comes to plug() stage, after it's been fully
initialized (including being reset), which fixes race condition [2]
without need for an extra post_plug() callback.

Roman Bolshakov b4e1af8961 i386: hvf: Fix register refs if REX is present
According to Intel(R)64 and IA-32 Architectures Software Developer's
Manual, the following one-byte registers should be fetched when REX
prefix is present (sorted by reg encoding index):
AL, CL, DL, BL, SPL, BPL, SIL, DIL, R8L - R15L

The first 8 are fetched if REX.R is zero, the last 8 if non-zero.

The following registers should be fetched for instructions without REX
prefix (also sorted by reg encoding index):
AL, CL, DL, BL, AH, CH, DH, BH

Current emulation code doesn't handle accesses to SPL, BPL, SIL, DIL
when REX is present, thefore an instruction 40883e "mov %dil,(%rsi)" is
decoded as "mov %bh,(%rsi)".

That caused an infinite loop in vp_reset:

Pavel Dovgalyuk ca9759c2a9 replay: don't process events at virtual clock checkpoint
As QEMU becomes more multi-threaded and non-synchronized, checkpoints
move from thread to thread. And the event queue that processed at checkpoints
should belong to the same thread in both record and replay executions.
This patch disables asynchronous event processing at virtual clock
checkpoint, because it may be invoked in different threads at record and
replay. This patch is temporary fix until the checkpoints are completely
refactored.

Artem Pisarenko 05ff8dc32f Revert some patches from recent [PATCH v6] "Fixing record/replay and adding reverse debugging"
That patch series introduced new virtual clock type for use in external
subsystems. It breaks desired behavior in non-record/replay usage
scenarios due to a small change to existing behavior.  Processing of
virtual timers belonging to new clock type is kicked off to the main
loop, which makes these timers asynchronous with vCPU thread and,
in icount mode, with whole guest execution. This breaks expected
determinism in non-record/replay icount mode of emulation where these
"external subsystems" are isolated from the host (i.e. they are
external only to guest core, not to the entire emulation environment).

Example for slirp ("user" backend for network device):
User runs qemu in icount mode with rtc clock=vm without any external
communication interfaces but with "-netdev user,restrict=on". It expects
deterministic execution, because network services are emulated inside
qemu and isolated from host. There are no reasons to get reply from DHCP
server with different delay or something like that.

The next patches revert reimplements the same changes in a better way.
This reverts commit 87f4fe7653.
This reverts commit 775a412bf8.
This reverts commit 9888091404.

Thomas Huth 1a1ff38c55 hw/core/generic-loader: Compile only once, not for each target
The generic-loader is currently compiled target specific due to one
single "#ifdef TARGET_WORDS_BIGENDIAN" in the file. We have already a
function called target_words_bigendian() for this instead, so we can
put the generic-loader into common-obj to save some compilation time.

Thomas Huth c95ac10340 cpu: Provide a proper prototype for target_words_bigendian() in a header
We've got three places already that provide a prototype for this
function in a .c file - that's ugly. Let's provide a proper prototype
in a header instead, with a proper description why this function should
not be used in most cases.

Thomas Huth 97ff87c0ed qemu/compiler: Wrap __attribute__((flatten)) in a macro
Older versions of Clang (before 3.5) and GCC (before 4.1) do not
support the "__attribute__((flatten))" yet. We don't care about
such old versions of GCC anymore, but since Clang 3.4 is still
used in EPEL for RHEL7 / CentOS 7, we should not use this attribute
directly but with a wrapper macro instead.

Helge Deller 5f538f7532 target/hppa: Raise exception 26 on emulated hardware
On PCXS chips (PA7000, pa 1.1a), trap #18 is raised on memory faults,
while all later chips (>= PA7100) generate either trap #26, #27 or #28
(depending on the fault type).

Since the current qemu emulation emulates a B160L machine (with a
PA7300LC PCX-L2 chip, we should raise trap #26 (EXCP_DMAR) instead
of #18 (EXCP_DMP) on access faults by the Linux kernel to page zero.

With the patch we now get the correct output (I tested against real
hardware):
 Kernel Fault: Code=26 (Data memory access rights trap)
instead of:
 Kernel Fault: Code=18 (Data memory protection/unaligned access trap)

Peter Maydell 2ef297af07 coccinelle: new inplace-byteswaps.cocci to remove inplace-byteswapping calls
Add a new Coccinelle script which replaces uses of the inplace
byteswapping functions *_to_cpus() and cpu_to_*s() with their
not-in-place equivalents. This is useful for where the swapping
is done on members of a packed struct -- taking the address
of the member to pass it to an inplace function is undefined
behaviour in C.

Peter Maydell ab44c7b71f target/arm: Initialize ARMMMUFaultInfo in v7m_stack_read/write
The get_phys_addr() functions take a pointer to an ARMMMUFaultInfo
struct, which they fill in only if a fault occurs. This means that
the caller must always zero-initialize the struct before passing
it in. We forgot to do this in v7m_stack_read() and v7m_stack_write().
Correct the error.
