InternalGetDirectGopContext()

CONST CONSOLE_GOP_CONTEXT * InternalGetDirectGopContext

(

VOID

)

Definition at line 635 of file ConsoleGop.c.

OcProvideConsoleGop()

EFI_STATUS OcProvideConsoleGop

(

IN BOOLEAN

Route

)

Ensure installed GOP protocol on ConOut handle.

Definition at line 81 of file ConsoleGop.c.

OcReconnectConsole()

VOID OcReconnectConsole

(

VOID

)

Perform console reconnection.

Definition at line 482 of file ConsoleGop.c.

OcUseDirectGop()

EFI_STATUS OcUseDirectGop

(

IN INT32

CacheType

)

Use direct GOP renderer for console.

Parameters

[in]	CacheType	Caching type, e.g. CacheWriteCombining or -1 to disable.
[in]	Rotation	Rotation scheme in degrees (must be one of 0, 90, 180, 270).

Return values

EFI_SUCCESS

on success.

Definition at line 536 of file ConsoleGop.c.

RotateMode()

STATIC VOID RotateMode	(	IN OUT EFI_GRAPHICS_OUTPUT_PROTOCOL *	This,
		IN UINT32	Rotation )

Translate current GOP mode to custom (rotated) mode. Both original and custom modes are saved.

Parameters

[in,out]	This	GOP protocol to update.
[in]	Rotation	Rotation angle.

Definition at line 269 of file ConsoleGop.c.

SwitchMode()

STATIC VOID SwitchMode	(	IN OUT EFI_GRAPHICS_OUTPUT_PROTOCOL *	This,
		IN BOOLEAN	UseCustom )

Update current GOP mode to represent either custom (rotated) or original mode. In general custom mode is used, but to call the original functions it is safer to switch to original.

Parameters

[in,out]	This	GOP protocol to update.
[in]	Source	Source mode.
