Function Documentation

start_vmm()

int64_t start_vmm ( uint64_t  arg )

noexcept

Start VMM

This function starts the VMM. The driver entry uses the ELF loader to call this "C" function from the kernel. Prior to executing this function, a new stack is provided, and all exceptions are caught prior to completing. To start the VMM, this function calls the vcpu_manager's start function, which begins the processing of starting the vmm.

Precondition

expects: none

Postcondition

ensures: none

Parameters

arg	unused (likely will contain the cpu's core # in the future)

Returns

ENTRY_SUCCESS on success, ENTRY_ERROR_UNKNOWN otherwise.

stop_vmm()

int64_t stop_vmm ( uint64_t  arg )

noexcept

Stop VMM

This function stops the VMM. The driver entry uses the ELF loader to call this "C" function from the kernel. Prior to executing this function, a new stack is provided, and all exceptions are caught prior to completing. To stop the VMM, this function calls the vcpu_manager's stop function, which begins the processing of stopping the vmm.

Precondition

expects: none

Postcondition

ensures: none

Parameters

arg	unused (likely will contain the cpu's core # in the future)

Returns

ENTRY_SUCCESS on success, ENTRY_ERROR_UNKNOWN otherwise.

local_init()

int64_t local_init

(

struct section_info_t *

info

)

Local Init

Initialized a binary / module. This is very similar to _init that GCC uses on Linux.This is called by the driver entry as each module. Each module has this function as it is statically linked with each module as it is compiled by the gcc wrapper

Precondition

expects: info != nullptr

Postcondition

ensures: none

Parameters

info	a pointer to the section info structure that is used by the init funcion.

Definition at line 80 of file misc_no_hyper_or_libcxx.cpp.

local_fini()

int64_t local_fini

(

struct section_info_t *

info

)

Local Fini

Initialized a binary / module. This is very similar to _fini that GCC uses on Linux. This is called by the driver entry as each module. Each module has this function as it is statically linked with each module as it is compiled by the gcc wrapper

Precondition

expects: info != nullptr

Postcondition

ensures: none

Parameters

info	a pointer to the section info structure that is used by the fini funcion.
