Log Message:

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 87f4fe7653baf55b5c2f2753fe6003f473c07342.
This reverts commit 775a412bf83f6bc0c5c02091ee06cf649b34c593.

qemu-timer: introduce timer attributes
Attributes are simple flags, associated with individual timers for their
whole lifetime. They intended to be used to mark individual timers for
special handling when they fire.
New/init functions family in timer interface updated and refactored (new
'attribute' argument added, timer_list replaced with timer_list_group+type
combinations, comments improved to avoid info duplication). Also existing
aio interface extended with attribute-enabled variants of functions,
which create/initialize timers.

qemu-timer: avoid checkpoints for virtual clock timers in external subsystems
Adds EXTERNAL attribute definition to qemu timers subsystem and assigns
it to virtual clock timers, used in slirp (ICMP IPv6) and ui (key queue).
Virtual clock processing in rr mode can use this attribute instead of a
separate clock type.

target-i386: kvm: do not initialize padding fields
The exception.pad field is going to be renamed to pending in an upcoming
header file update. Remove the unnecessary initialization; it was
introduced to please valgrind (commit 7e680753cfa2) but they were later
rendered unnecessary by commit 076796f8fd27f4d, which added the "= {}"
initializer to the declaration of "events". Therefore the patch does
not change behavior in any way.

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.

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:

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.

Make hyperv_testdev slightly easier to follow and enhance in future.
For that, put the hyperv sint routes (wrapped in a helper structure) on
a linked list rather than a fixed-size array. Besides, this way
HvSintRoute can be treated as an opaque structure, allowing for easier
refactoring of the core Hyper-V SynIC code in followup pathches.

hyperv: allow passing arbitrary data to sint ack callback
Make sint ack callback accept an opaque pointer, that is stored on
sint_route at creation time.
This allows for more convenient interaction with the callback.
Besides, nothing outside hyperv.c should need to know the layout of
HvSintRoute fields any more so its declaration can be removed from the
header.

hyperv: only add SynIC in compatible configurations
Certain configurations do not allow SynIC to be used in QEMU. In
particular,
- when hyperv_vpindex is off, SINT routes can't be used as they refer to
the destination vCPU by vp_index
- older KVM (which doesn't expose KVM_CAP_HYPERV_SYNIC2) zeroes out
SynIC message and event pages on every msr load, breaking migration
OTOH in-KVM users of SynIC -- SynIC timers -- do work in those
configurations, and we shouldn't stop the guest from using them.
To cover both scenarios, introduce an X86CPU property that makes CPU
init code to skip creation of the SynIC object (and thus disables any
SynIC use in QEMU) but keeps the KVM part of the SynIC working.
The property is clear by default but is set via compat logic for older
machine types.
As a result, when hv_synic and a modern machine type are specified, QEMU
will refuse to run unless vp_index is on and the kernel is recent
enough. OTOH with an older machine type QEMU will run fine with
hv_synic=on against an older kernel and/or without vp_index enabled but
will disallow the in-QEMU uses of SynIC (in e.g. VMBus).

hyperv: make overlay pages for SynIC
Per Hyper-V spec, SynIC message and event flag pages are to be
implemented as so called overlay pages. That is, they are owned by the
hypervisor and, when mapped into the guest physical address space,
overlay the guest physical pages such that
1) the overlaid guest page becomes invisible to the guest CPUs until the
overlay page is turned off
2) the contents of the overlay page is preserved when it's turned off
and back on, even at a different address; it's only zeroed at vcpu
reset
This particular nature of SynIC message and event flag pages is ignored
in the current code, and guest physical pages are used directly instead.
This happens to (mostly) work because the actual guests seem not to
depend on the features listed above.
This patch implements those pages as the spec mandates.
Since the extra RAM regions, which introduce migration incompatibility,
are only added at SynIC object creation which only happens when
hyperv_synic_kvm_only == false, no extra compat logic is necessary.

hyperv: add synic message delivery
Add infrastructure to deliver SynIC messages to the SynIC message page.
Note that KVM may also want to deliver (SynIC timer) messages to the
same message slot.
The problem is that the access to a SynIC message slot is controlled by
the value of its .msg_type field which indicates if the slot is being
owned by the hypervisor (zero) or by the guest (non-zero).
This leaves no room for synchronizing multiple concurrent producers.
The simplest way to deal with this for both KVM and QEMU is to only
deliver messages in the vcpu thread. KVM already does this; this patch
makes it for QEMU, too.
Specifically,
- add a function for posting messages, which only copies the message
into the staging buffer if its free, and schedules a work on the
corresponding vcpu to actually deliver it to the guest slot;
- instead of a sint ack callback, set up the sint route with a message
status callback. This function is called in a bh whenever there are
updates to the message slot status: either the vcpu made definitive
progress delivering the message from the staging buffer (succeeded or
failed) or the guest issued EOM; the status is passed as an argument
to the callback.
