gx.h

<B>Digital的Unix操作系统VAX 4.2源码</B>

/*
 * @(#)gx.h	4.5	(ULTRIX)	12/6/90
 *
 * 06-Dec-90 -- Randall Brown 
 *	Added #define LK_MODE_CHG_ACK.
 *
 * 22-Oct-90 -- Sam Hsu
 *	Change tablet puck button definitions to match tablet.h.
 *
 * 20-Apr-90  -- Sam Hsu
 *	Add GX_CONSOLE.  Remove extraneous test in GX_HAVESERVER.  Define
 *	GX_MULTIOPEN.  Add STIC_INT_WE.  Remove QIO_MAPSLOT.  Moved cursor
 *	and colormap to common area, then backed out of that change due to
 *	apprehension over interface change.
 *
 * 04-Apr-90  -- Sam Hsu
 *	Turn off debugging for UEG copy.  Add IPLTTY() macro.
 *
 * 28-Mar-90  -- Sam Hsu
 *	gxInfo->gxo is now a permanent fixture.  Put in bug fix for STIC
 *	addressing found by Paul.  Set debug level on panic to reduce output.
 *	Remove some no-longer-used #define's.  Add mapslot ioctl for bmk.
 *	IAMSERVER/HAVESERVER macros.  Console font cell size 12x21->11x20.
 *	Console text fg index 0x1 instead of 0xff.  Clean up DUPBYTEs to
 *      generate less code.
 *
 * 29-Jan-90  -- Sam Hsu
 *	Redefine debugging macros to be dynamic, so one can change them
 *	in a running kernel.
 *
 * 17-Jan-90  -- Sam Hsu
 *	Move STIC definitions from stamp.h into here... get rid of 3.1C
 *	ioctl definitions.
 *
 * 18-Dec-89  -- Sam Hsu
 *	Include Paul J's macros for cons'ing up STIC DMA poll addresses,
 *	with the usual name changes from GA_ to GX_.  Both 2/3DA systems
 *	use the same scheme (originally in ga.h).
 *
 * 12-Dec-89  -- Paul Jensen
 *	Use new Bt459 interface.  Change _TEXT_FG to something which
 *	works on 8- and 24-plane systems.  Define verbosity levels
 *	for FDEBUG, as per Sam's suggestion.
 *
 *  7-Dec-89  -- Paul Jensen
 *	Define the ring buffer to be an offset from the top of the
 *	gxPriv structure (ringbufferoffset), instead of an
 *	array-of-int.
 *
 * 30-Nov-89  -- Sam Hsu
 *	Convert/merge into 4.0 source pool.
 *
 * 16-Oct-89  -- Sam Hsu
 *	non-KERNEL programs needn't include stamp.h and gao.h anymore.
 *
 * 21-Sep-89  -- Sam Hsu
 *	KMAX3D ioctl.h file.  Removed extraneous fields from pm_info.
 *
 * 22-Aug-89  -- Sam Hsu
 *	Based on pm.h  Add KMAX3D changes.  Include gao.h and stamp.h.
 *
