Requirement: in CPU partition VM (RTVM), vtune or perf can be used to
sample hotspot code path to tune the RT performance, It need support
PMU/PEBS (Processor Event Based Sampling). Intel TCC asks for it, too.
It exposes PEBS related capabilities/features and MSRs to CPU
partition VM, like RTVM. PEBS is a part of PMU. Also PEBS needs
DS (Debug Store) feature to support. So DS is exposed too.
Limitation: current it just support PEBS feature in VM level, when CPU
traps to HV, the performance counter will stop. Perf global control
MSR is used to do this work. So, the counters shall be close to native.

NMI is used to notify LAPIC-PT RTVM, to kick its CPU into hypervisor.
But NMI could be used by system devices, like PMU (Performance Monitor
Unit). So use INIT signal as the partition CPU notification function, to

Also remove unused NMI as notification related code.

Tracked-On: #6690

The launch script generator today (and the scripts that it generates) is
fundamentally built on the concept of PCI device classes, with the
restriction that at most one PCI function per class can be passed through
to a post-launched VM. This has put inproper constraint on the scenarios
users can set up, especially on server platforms or those with SR-IOV
capable devices.
As it is too tedious to change such deep-rooted concept, this patch
rewrites the launch script generator and refines the structure of the
generated scripts so that PCI functions are identified only by their
BDF.
This change serves as a mandatory step to align the way how passthrough
devices are configured for pre-launched and post-launched VMs, which
eventually allows us to present a unified view in the configurator for
assigning passthrough device.
v2 -> v3:
* Rename sos_id to service_vm_id and user_vmid to user_vm_id.
* Refine a couple of info messages in the launch script template.
v1 -> v2:
* Fix wording issues identified during review.
* Exit when the out_dir is an existing regular file.

When the virtio-XXX pci devices fall back to legacy PCI intx,
the pci_irq_assert is called to inject the interrupt and then
the pci_irq_deassert is used to mark the completion of PCI interrupt.
Currently the HV vIOAPIC uses the pin_state for the interrupt injection
of legacy PCI intx. In such case it will fail to inject the PCI legacy
intx and the guest system fails to be booted when adding the boot option
of "pci=nomsi".
PCI legacy INTx usually use active low level trigger mode as it is Open-Drain
state and allows multitple interrupt signals to share a single line.
https://wiki.osdev.org/PCI_Local_Bus_Signals
In such case DM needs to set the correct state for the PCI device so that the
HV vIOAPIC can help to inject the PCI legacy intx.
BTW: When the MSI/MSIX is used for PCI device, it uses another mechanism
to inject the interrupt. It is harmless to configure the initial state.

'mevent_lmutex' is initialized as default type,
while attempting to recursively lock on this
kind of mutext results in undefined behaviour.
Recursively lock on 'mevent_lmutex' can be detected
in mevent thread when user tries to trigger system
reset from user VM, in this case, user VM reboot hang.
The backtrace for this issue:
#1 in mevent_qlock () at core/mevent.c:93
#2 in mevent_delete_even at core/mevent.c:357
===>Recursively LOCK
#3 in mevent_delete_close at core/mevent.c:387
#4 in acrn_timer_deinit at core/timer.c:106
#5 in virtio_reset_dev at hw/pci/virtio/virtio.c:171
#6 in virtio_console_reset at
hw/pci/virtio/virtio_console.c:196
#7 in virtio_console_destroy at
hw/pci/virtio/virtio_console.c:1015
#8 in virtio_console_teardown_backend at
hw/pci/virtio/virtio_console.c:1042
#9 in mevent_drain_del_list () at
core/mevent.c:348 ===> 1st LOCK
#10 in mevent_dispatch () at core/mevent.c:472
#11 in main at core/main.c:1110
So the root cause is:
mevent_mutex lock is recursively locked by mevent thread
itself (#9 for this first lock and #2 for recursively lock),
which is not allowed for mutex with default attribute.
This patch changes the mutex type of 'mevent_lmutex'
from default to "PTHREAD_MUTEX_RECURSIVE", because
recrusively lock shall be allowed as user of mevent
may call mevent functions (where mutex lock maybe required)
in teardown callbacks.
