		size_t	width,
		size_t	height,
		rgb_t	colour

virtual

Todo:: This needs to properly handle the case where there's more than one byte per pixel? (or less, I guess)

Here is the caller graph for this function:

bool VbeDisplay::getCurrentScreenMode ( Display::ScreenMode & sm )

virtual

Returns the current screen mode.

Returns: True if operation succeeded, false otherwise.

Reimplemented from Display.

Definition at line 129 of file VbeDisplay.cc.

void * VbeDisplay::getFramebuffer ( )

virtual

Returns a pointer to a linear framebuffer. Returns 0 if none available.

Warning: Not intended to be used - use the buffer functions instead.

Reimplemented from Display.

Definition at line 118 of file VbeDisplay.cc.

bool VbeDisplay::getPixelFormat ( Display::PixelFormat & pf )

virtual

Returns the format of each pixel in the framebuffer, along with the bits-per-pixel.

Returns: True if operation succeeded, false otherwise.

Reimplemented from Display.

Definition at line 123 of file VbeDisplay.cc.

bool VbeDisplay::getScreenModes ( List< Display::ScreenMode * > & sms )

virtual

Fills the given List with all of the available screen modes.

Returns: True if operation succeeded, false otherwise.

Reimplemented from Display.

Definition at line 135 of file VbeDisplay.cc.

VbeDisplay::rgb_t * VbeDisplay::newBuffer ( )

virtual

Returns a new back buffer. This is the primary method for drawing to the screen. The buffer returned is in RGB 24-bit format and is the width and height of the screen.

Reimplemented from Display.

Definition at line 254 of file VbeDisplay.cc.

References ERROR, Framebuffer::getFramebuffer(), PhysicalMemoryManager::getPageSize(), PhysicalMemoryManager::instance(), Display::PixelFormat::nBpp, Display::PixelFormat::nPitch, MemoryRegion::virtualAddress(), and VirtualAddressSpace::Write.

Referenced by setScreenMode().

Here is the caller graph for this function:

bool VbeDisplay::setScreenMode ( Display::ScreenMode sm )

virtual

Sets the current screen mode.

Returns: True if operation succeeded, false otherwise.

Todo:: Assumption may be wrong?

Reimplemented from Display.

Definition at line 163 of file VbeDisplay.cc.

bool VbeDisplay::setScreenMode ( size_t modeId )

virtual

Sets the current screen mode using a set of well-defined VBE IDs. Example: 0x117 = 1024x768x16.

Reimplemented from Display.

Definition at line 141 of file VbeDisplay.cc.

inlinevirtual

Sets the current screen mode using a width, height, and pixel depth

Todo:: "Closest match": allow a threshold for a match in case the specific mode specified cannot be set.
