PlatformDebugLibIoPortDetect()

BOOLEAN EFIAPI PlatformDebugLibIoPortDetect

(

VOID

)

Helper function to return whether the virtual machine has a debug I/O port. PlatformDebugLibIoPortFound can call this function directly or cache the result.

Return values

TRUE	if the debug I/O port device was detected.
FALSE	otherwise

Always return TRUE without detection as the debug I/O port is always present.

Return values

TRUE	The debug I/O port is always present.

Return the result of detecting the debug I/O port device.

Return values

TRUE	if the debug I/O port device was detected.
FALSE	otherwise

PlatformDebugLibIoPortFound()

BOOLEAN EFIAPI PlatformDebugLibIoPortFound

(

VOID

)

Return whether the virtual machine has a debug I/O port. DebugLib.c calls this function instead of PlatformDebugLibIoPortDetect, to allow caching if possible.

Return values

TRUE	if the debug I/O port device was detected.
FALSE	otherwise

At the first call, check if the debug I/O port device is present, and cache the result for later use. At subsequent calls, return the cached result.

Return values

TRUE	if the debug I/O port device was detected.
FALSE	otherwise

Return the result of detecting the debug I/O port device.

Return values

TRUE	if the debug I/O port device was detected.
FALSE	otherwise
