DESCRIPTION
This module defines the data structures used for information flow between
wind river Hypervisor and a Virtual Board. There are three structures employed
for this purpose:
\ms
\m -
configuration
\m -
status
\m -
control
\me
The configuration structure is the first data exchanged between a given virtual
board and Hypervisor kernel. The pointers to the status and control structures are
derived from the configuration structure. It contains pointers to the status,
control and other information about resources assigned to a virtual board.
The configuration data is shared accross the cores in the same virtual board unlike
the data in the control and status structure which may be different for each core.
The information in the configuration structure is static in the sense that the data
it contains remain unmodified at least during the life of a boot cycle.
The status structure is used to inform a virtual core at runtime about the state it
is excecuting (interrupts, vmmu, elapsed time etc...).
The control structure is put in place as a fast method to pass information from
the VB to Hypervisor or vis-versa. For examples during a virtual board context
switch the control structure allows to store the incoming virtual board context
setting before the virtual board sends a Hypercall using VBI_CTX_LOAD().
Hypervisor passes (as parameter) a pointer of the configuration structure to the
entry function of the virtual core and a boot option flag.
The VBI library provides a initialization function vbiInit() to ensures that
Hypervisor version number is compatible with the VBI library in use. If the versions
match then the configuration, status and control pointers are stored respectively to
wrhvVbConfig, wrhvStatus and wrhvVbControl.
Therefore a virtual board must always call vbiInit() before accessing any data
provided by Hypervisor nor send a hypercall to it. Refer to to vbiInit() description
in the VBI API description document for more information.
Once the VBI library is initialized the virtual board should employ the provided
macros in order to access the fieds in wrhVbConfig, wrhvVbStatus and wrhvVbControl
data structures. Accessing these structures via the VBI function guaranties source
level compatibily between VBI versions.
A guest OS should port vbiInit(), the access macros along with the necessary header
files where the data structrures layout is defined.
To be aware:
\ms
\m -
Changing the order of the field this structure may have serious impact on the
integrity of the system. It exists hand crafted macros to match the C
structures offset. Therefore any change should be reflected in the macros
\m -
When a virtual core boots the VMMU is not enbled but a programmer may choose
to turn-on the VMMU. In that scenario proper care must be taken to ensure that
the address where the control, status or configureation structure is reflected
in the VMMU mapping. Technically these area should be treated as I/O region
therefore it is encouraged that they are identity mapped.

*
* VB_CONTROL - Virtual board cores control structure
*
* VB_CONTROL is a data type that defines a virtual core's control structure.
* This is called the control structure because a core uses to modify it's
* state. The code running in the context of a virtual core puts the desired
* setting in this control and passes to Hypervisor via the Hypercall mechanism.
* It is suggested to use the provided APIs for manipulating the virtual core
* control structure instead of directly accessing it's members.
* Typically use cases for this structure are for following:
*\ms
*\m -
* During context switch for setting the incoming context's register state.
* For more information about this refer to VBI_CTX_LOAD() description in the
* architecture supplement API documentation.
*\m -
* Locking/unlocking the virtual core interrupts.
*\m -
* Loading the VMMU configuration data.
*\m -
* VIOAPIC configuration registers.
*
*\me
* The control structure definition is generic accross the various architecture
* flavours supported by Hypervisor with the exception of the emulated registers.
* There is an architecture specific extention available via a pointer of type
* VB_ARCH_STATUS_REGS to accomodate the registers unique for a given hardware
* platform.
* However that does imply that other fields defined in this structure are used
* in every architecture. A field is considered generic if it is usefull at least to
* two CPU families but not necessary to all CPUs.
* The VIOAPIC is the only field that is meaning full accross all architectures.
* Note that some architectures like Intel with VT technology don't require emulated
* registers. The pointer of emulated registers is included only if
*_WRHV_ARCH_HAS_CTRL_REGS flag is defined. The control structure is mapped
* with read/write access attribute for the purpose of serving as duplex
* communication channel between Hypervisor and a virtual core. This mechanism
* is fall back when it is not possible to use registers for transmitting data
* from the virtual core to Hypervisor or vis-versa. More information about
* VB_ARCH_CONTROL_REGS may be found in the architecture supplement document.
