Minggui Cao 42d5533e6f HV: makefile: to avoid duplicated build libs
1. improve makefile to avoid duplicated build libs when make
in acrn-hypervisor/hypervisor directory to build HV only.

2. for debug/release library just select one makefile to build

Li, Fei1 cc47dbe769 hv: uart: enable early boot uart
Enable uart as early as possible to make things easier for debugging.
After this we could use printf to output information to the uart. As for
pr_xxx APIs, they start to work when init_logmsg is called.

Conghui Chen 4d88b2bb65 hv: bugfix for sbuf reset
The sbuf is allocated for each pcpu by hypercall from SOS. Before launch
Guest OS, the script will offline cpus, which will trigger vcpu reset and
then reset sbuf pointer. But sbuf only initiate once by SOS, so these
cpus for Guest OS has no sbuf to use. Thus, when run 'acrntrace' on SOS,
there is no trace data for Guest OS.
To fix the issue, only reset the sbuf for SOS.

Conghui Chen 513c9f8744 HV: vuart: move the vuart code to dm directory
As there is a requirement for conmunication between VMs on uart port,
but for Pre-launched VM, the only way is to create vuart for each VM and
connect them at hypervisor side. So, the vuart code should be moved from
/debug to /dm so that they can also be used in release version.
For the console related code, as no need to support in release version,
so leave them at debug directory.

Conghui Chen 235d886103 HV: vuart: enable vuart console for VM
In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.

Zide Chen aee9f3c666 hv: reset per cpu sbuf pointers during vcpu reset
When shutting down SOS VM, the shared sbuf is released from guest OS, but
the per cpu sbuf pointers in hypervisor keep inact. This creates a problem
that after SOS is re-launched, hypervisor could write to the shared
buffer that no longer exists.

This patch implements sbuf_reset() and call it from reset_vcpu() to
reset sbuf pointers.

Min Lim 9e917057e9 profiling: split profiling_vmexit_handler into two functions
This patch fixes incorrect vm_id captured when sampling PMU data. Currently,
the vm_id gets attributed to ACRN hypervisor, rather than actual guest vm_id.

The issue is identified that the existing code captures the guest vm info
after vmexit_hander function is completed, in which the profiling module
points its context to VMM. When the vmexit happens by PMI, the guest context
should be captured so that the attribution to proper guest vm can happen.

This change will also allow to capture more accurate TSC when vmexit happens.
