* FILE: ssbits.c
*
* AUTHOR: Benny Ng
*
* DESCRIPTION:
* This module implements the DrvSaveScreenBits() for
* Laguna NT driver.
*
* MODULES:
* DrvSaveScreenBits()
*
* REVISION HISTORY:
* 6/20/95 Benny Ng Initial version
*
* $Log: X:/log/laguna/nt35/displays/cl546x/SSBITS.C $
*
* Rev 1.18 Apr 28 1998 12:51:44 frido
* PDR#11389. I have disabled DrvSaveScreenBits on 2MB boards. We
* seem to run out of memory and the memory manager moves the blocks
* to a different place causing corruption.
*
* Rev 1.17 Mar 04 1998 15:34:18 frido
* Added new shadow macros.
*
* Rev 1.16 Nov 03 1997 11:18:10 frido
* Added REQUIRE macros.
*
* Rev 1.15 08 Aug 1997 17:24:22 FRIDO
* Added support for new memory manager.
*
* Rev 1.14 09 Apr 1997 10:49:28 SueS
* Changed sw_test_flag to pointer_switch.
*
* Rev 1.13 08 Apr 1997 12:27:40 einkauf
*
* add SYNC_W_3D to coordinate MCD/2D hw access
*
* Rev 1.12 26 Nov 1996 10:44:02 SueS
* Changed WriteLogFile parameters for buffering.
*
* Rev 1.11 13 Nov 1996 17:08:46 SueS
* Changed WriteFile calls to WriteLogFile.
*
* Rev 1.10 07 Nov 1996 16:09:08 bennyn
*
* Added no offscn allocation if DD enabled
*
* Rev 1.9 23 Aug 1996 09:10:38 noelv
* Save unders are now discardable.
*
* Rev 1.2 22 Aug 1996 17:07:14 frido
* #ss - Added validation of saved area before restoring or freeing it.
*
* Rev 1.1 15 Aug 1996 11:39:54 frido
* Added precompiled header.
*
* Rev 1.0 14 Aug 1996 17:16:30 frido
* Initial revision.
*
* Rev 1.7 18 Jun 1996 12:39:34 noelv
* added debug information.
*
* Rev 1.6 28 May 1996 15:11:30 noelv
* Updated data logging.
*
* Rev 1.5 16 May 1996 15:01:02 bennyn
*
* Add PIXEL_ALIGN to allocoffscnmen()
*
* Rev 1.4 20 Mar 1996 16:09:42 noelv
*
* Updated data logging
*
* Rev 1.3 05 Mar 1996 12:01:46 noelv
* Frido version 19
*
* Rev 1.1 20 Jan 1996 01:16:48 frido
*
*
* Rev 1.4 15 Jan 1996 17:00:08 NOELV
* AB workaround reductions
*
* Rev 1.3 20 Oct 1995 11:21:50 NOELV
*
* Was leaking offscreen memory. Now it releases its memory after resoring.
*
* Rev 1.2 04 Oct 1995 10:17:36 NOELV
*
* Used updated write macros.
*
* Rev 1.1 21 Aug 1995 13:52:44 NOELV
* Initial port to real hardware.
* Converted all 32 bit register writes to 2 16 bit regiser writes.
*
* Rev 1.0 25 Jul 1995 11:23:20 NOELV
* Initial revision.
*
* Rev 1.2 06 Jul 1995 09:59:10 BENNYN
*
*
* Rev 1.1 05 Jul 1995 08:39:44 BENNYN
* Initial version
*
* Rev 1.0 29 Jun 1995 14:20:44 BENNYN
* Initial revision.
