f912953539 HV:treewide:Update exec_vmread/exec_vmwrite and exec_vmread64/exec_vmwrite64
In the hypervisor, VMCS fields include 16-bit fields,
32-bit fields, 64-bit fields and natural-width fields.
In the current implement,  there are exec_vmread/exec_vmwrite
used for accessing 32-bit fields, 64-bit field and
natural-width fields. This usage will confue developer.
So there are many type casting for the return value and
parameters vmread/vmwrite operations.

Since exec_vmread/exec_vmwrite and exec_vmread64/exec_vmwrite64
are the same, update current exec_vmread/exec_vmwrite
implement into exec_vmread64/exec_vmwrite64 implement
and add MACRO define for exec_vmread/exec_vmwrite in
head file;
To access 64-bit fields in VMCS, callers use
exec_vmread64/exec_vmwrite64;
Update related variables type for vmread/vmwrite operations;
Update related caller according to VMCS fields size.

Note:Natural-width fields have 64 bits on processors
that support Intel 64 architecture.To access natural-width
fields in VMCS, callers still use exec_vmread/exec_vmwrite,
keep the current implementation.

V1--V2:
        This is new part of this patch serial to only
        update 64-bit vmread/vmread opertions and related
        caller, for netural width fields, still use exec_vmread
	or exec_vmwrite.
V2-->V3:
	Fix few mistake updations for netural fields in VMCS,
	just keep exec_vmread/exec_vmwrite to access them;
	Fix few mistake updations for 64-bit fields in VMCS.
V3--V4:
	Add "016ll" for 64-bit variable in log function;
	Few updates for coding style;
	Rename lssd32_idx as tr_sel in VMX module.
V4-->V5:
	Use CPU_NATURAL_LAST in the vm_get_register and
	vm_set_register to make condition statement more
	understandable.

69ebf4c6e6 HV: vioapic: cleaning up integral-type-related violations
This patch cleans up the integral-type-related violations after the access
pattern to RTEs is unified. Major changes include:

    1. vioapic_mmio_read(), vioapic_mmio_write() and vioapic_mmio_rw() assumes
       the size of the register to be accessed is always 4, which is checked in
       vioapic_mmio_access_handler(). Thus they no longer takes the unused
       ''size'' parameter.

    2. Typical integral-type-related violation fixes including 'U' suffixes,
       type of local variables, conversion specification in format strings, etc.

v1 -> v2:

    * Drop duplicated definitions to IOAPIC register offsets.
    * Drop the ''size'' parameter of vioapic_mmio_[read|write] and
      vioapic_mmio_rw since vioapic_mmio_access_handler() ensures that size is
      always 4.

a1069a5117 HV: ioapic: unify the access pattern to RTEs
There are two different ways the current implementation adopts to access ioapic
RTEs:

    1. As two 32-bit registers (typically named ''low'' and ''high''), or

    2. As one 64-bit register (typically named ''rte'').

Two issues arise due to the mixed use of these two patterns.

    1. Additional conversions are introduced. As an example, ioapic_get_rte()
       merges two RTE fragments into a uint64_t, while some callers break it
       back to ''low'' and ''high'' again.

    2. It is tricky to choose the proper width of IOAPIC_RTE_xxx constants. SOS
       boot failure is seen when they are 32-bit due to the following code:

           /* reg is uint64_t */
           vioapic->rtbl[pin].reg &= ~IOAPIC_RTE_REM_IRR;

       while making them 64-bit leads to implicit narrowing when the RTEs are accessed
       in the low & high pattern.

This patch defines a union ''ioapic_rte'' and unifies the access pattern
to IOAPIC and vIOAPIC RTEs.

v1 -> v2:

    * Instead of two 32-bit ''low'' and ''high'', define a union that allows
      either 32-bit or 64-bit accesses to RTEs.

 - add a range check to ensure that there is no overflow

d0c61ce424 HV: trace: integral type cleanup
In the current trace.h, the entries use proper unsigned types while some
function prototypes and local variables still use plain 'int', resulting in
implicit signedness conversions.

This patch makes the following conversions:

    * evid: int -> uint32_t,
    * n_data & cpu: 8-bit bit-field -> uint8_t,
    * local variable holding the value from strnlen_s(): int -> size_t.

Note: In the following definition:

    struct trace_entry {
        uint64_t tsc; /* TSC */
        uint64_t id:48;
	....

c477138f19 HV: ioapic: convert pins to uint8_t
Currently IOAPIC pins are represented using various types, including uint16_t,
int, uint8_t and uint32_t. This patch converts all pins to uint8_t since the
maximum number of interrupt input pins per IOAPIC is limited to 240. The special
value IOAPIC_INVALID_PIN is defined to indicate that a valid pin cannot be
found.

This type clean up also has the following impacts.

    * The values in the ''legacy_irq_to_pin'' table are piggybacked with their
      trigger mode. This patch splits them as the piggyback prevents us from
      using a uint8_t[] for this table, and these two information are never used
      at the same time.

    * The ''offset'' parameter in ioapic_read_reg32 & ioapic_write_reg32 are
      promoted to uint32_t to minimize explicit type conversions and keep
      aligned with the type of formal parameters of mmio_(read|write)_long.

7a66c317b5 HV: Remove vm->attr.name
We define attr.name in struct vm and named as ("vm_%d", attr.id). attr.name only
be used in debug tool vm_list. It does't deserve to do so in OS created flow
(aka function create_vm). It's better to handle this in vm_list tool.

cc50165018 HV:treewide:Cleanup the type for parameters of bitmap
operations

For reducing sign conversion in hypervisor:
Update parameters of bitmap operations as unsigned type;
Update the input of related caller as unsigned type when the
caller's input parameter is const variable or the variable is
only used by bitmap operations.

V1-->V2:
        (1) Explicit casting for the first parameter
            of all bitmap operations;
        (2) Remove mask operation for explicit casting
            of all bitmap operations, since masking is
            useless. Otherwise, this trucation is dangerous.
V2-->V3:
        (1) Explicit casting for all bitmap operations parameter;
        (2) Masking bit offset with 6-bit;
        (3) Add few comments about bit offset.
V3-->V4:
        add '\' for some statement of bitmap macro

bfe47a7a91 HV: trace: Add nr of data and cpuid to trace_entry
Later patch will refactor acrntrace to make trace data output as raw data(binary)
and introduce a new tool(acrntrace_format) to parse raw data to human-readable
file.

Adding nr of data and cpuid to trace_entry will make it easy for acrntrace_format

5b43521461 hv: trap vm0 write/read pm1a/pm1b registers
ACRN needs to trap the pm1a/pm1b written/read from VM0. So we
could know when should we put the system to S3.

We will have two path back to VM0:
 - S3 enter/exit sucess. Will reset VM0 and jump to VM0 wakeup vec
   with real mode
 - S3 enter/exit failed. Will return to the next instruction of
   pm1a/pm1b register writing. VM0 will read the pm1a/pm1b evt
   register to check whether it's waked up or not.

 - reset BSP of VM0
 - set the BSP entry to saved VM0 wakeup vec and set BSP to real mode
 - start BSP

To match trampoline_spinlock release on ACRN Sx resume path, acquire
trampoline_spinlock if ACRN Sx enter fails.

02d819144e hv: add enter_s3
enter_s3 is main function for ACRN to enter S3 state with following
process:
 - pause vm0
 - save the wakeup vec of vm0 and set wakeup vec of ACRN. So
   resume from S3 will jump to ACRN wakeup
 - offline APs
 - update the main entry of trampoline to resume entry. After BSP
   is resume from S3, it will jump to resume entry instead of AP
   startup routine
 - turn off vmx
 - suspend devices
 - enter S3.

exit S3 with following process:
 - release trampoline_spinlock which is hold in trampoline code
 - resume devices
 - enable vmx
 - update the main entry of trampoline to AP startup routine.
 - online APs.

The following operations will be resume vm0 which will be added
in next patch.
