validateDetailedTiming

Reports whether a detailed timing is able to be programmed with the device.

Declaration

virtual IOReturn validateDetailedTiming( 
 void *description,
 IOByteCountdescripSize );

Parameters

  • description:

    A pointer to a IODetailedTimingInformationV2 structure. The driver should examine this description and change any fields that it cannot implement to reflect its closest possible implementation.

  • descripSize:

    sizeof(IODetailedTimingInformationV2)

Return Value

an IOReturn code. A return other than kIOReturnSuccess will prevent the system from installing the programmable mode.

Overview

IOFramebuffer subclasses may implement programmable mode functionality where the OS is able to install modes described by a detailed timing into the driver.
