Required Graphics-Mirror Driver Functions

NTDEV
1

The required list is (based on DDK Documentation):

DrvEnableDriver
DrvGetModes
DrvEnablePDEV
DrvCompletePDEV
DrvEnableSurface
DrvDisableSurface
DrvDisablePDEV
DrvDisableDriver
DrvAssertMode
DrvResetDevice

However, the mirror sample doesn’t implement all required functions. I’d
like to know if a mirror driver has a short required functions list. In
special, the function DrvGetModes(…), if it’s really required, how can I
fill the DEVMODEW?

Before you go too far with the mirror driver, just wanted to warn you that the mirror driver disables direct draw overlays on your PC. So, you could have a case in which your media player doesn’t run as expected, for example (see links below).

The last time I checked (1/2 a year ago) nobody on the newsgroups got around this. I’d be interested to find out if you, or anybody got around this, and if so, how.
