RESTORE_LATCHES (Function 25)

Call With

EBX: Contains a Windows VM Handle.

EBP: Points to the Windows VM's Client Registers.

Return Values

Save anything that you use. You must not fail this call. If it is hooked, it must be implemented.

Remarks

If you implement SAVE_LATCHES, you must also implement RESTORE_LATCHES. Many chipsets have a method by which the VGA processor latches can be directly saved and/or restored. If your hardware can do this, it increases the performance of your 4 plane VGA virtualization greatly if you implement SAVE_LATCHES and RESTORE_LATCHES.
