Windows CE .NET VoyagerGX driver Release Notes
==============================================

(1.00.01)
- Disabled the AC/DC power change detection mechanism to prevent occasional screen
  corruptions noticed on some Fujitsu systems.

Final Release Version 1.00.00
- Fix screen blank issues on non-CEPC platform, fixed by casting m_bUMA to UCHAR
  (weird bug: The problem is caused when OR-ing 3 different parameters - seems 
  like if all parameters are DWORD, then it will not work, need for one of the
  parameter to be UCHAR in non-CEPC platform)
- Added PanelSettings feature to enable user to modify the registers on the fly. 
  See readme.txt for detail usage explanation.
- Improved the copy method for SMISETTINGS structure
- Changed the way to define and implement new panel type.
  Plexus_800x600TFT and MSTN320x240 options are deprecated. See readme.txt on how to specify them.
- Merged UMA and non-UMA codes into single consistent codes base.
- Replaced and added many new VPE APIs functions.
- Fixed VideoPort capture no image issue - caused by Disabled ZVPort gate
- Change the BOB initial scale ratio - this may cause jitter on all previous ZVPort capture program 
  (Please review the codes for all those calling Video Port StartVideo function 
  - See latest VGXVPE7118 codes on how to eliminate direct hardware registers accesses and use
  VPE APIs instead for special configuration).
- Change the default Clock Polarity - May cause capture issue
- When registry flag DisplayType = 2 (CRT only), use panel plane & route panel data
  to CRT output.
- Fixed the line draw algorithm to round values instead of truncate.
- Fixed CETK DirectDraw Test failure of Overlays. When zoom feature is enabled, the
  Overlay Capability will be disabled.
- Fixed problem where cursor appears on both screens simultaneously in Multimon mode
  when running ddex1.exe (DirectDraw sample application).
- Fixed "no screen on 2nd monitor" Multimon (800x480 with 2 VGX boards) problem.

(0.03.15)
- modified 800x600 panel Hsync from 0xd3037f to 0xd4037f requested by Plexus.
- Added DMA API for Voyager GX.
- Added "SMI_NOBOOTARG" environment to handle devices without boot argument support.

(0.03.14)
- Added SSP API.
- Power Management change: added checking for the presence of SMI Audio driver before
  shutting 8051 down. If Audio driver is detected, 8051 is left alone.

(0.03.13)
- Added "CSCDisabled" registry to enable/disable front-end video CSC.

(0.03.12)
- Added "OverlayDisabled" registry to enable/disable overlay settings
- Change the default to backend overlay enabled
- Fixed the cropping issue during CSC front-end video playback.
- Change the default MCLK to 72Mhz for all mode.
- Enabled interpolation during stretch mode for Zoom APIs.
- Fixed line issue in UMA mode.
- Fixed the font corrupt issue when scrolling in UMA mode.

(0.03.11)
- Modified I2C to program the direction bit, added more error codes to the API.
- Add two environment variables "SMI_DISABLE_INT_MGR" and "SMI_DISABLE_AUTO_PWRMGR"
  to disable interrupt management and auto power management. WinCE 3.0 needs to set 
  those two environment variables equal to 1.
- Blocked switching to active power modes from PowerHook while in sleep or standby.
- Implemented interrupt management that supports both host cpu and pci systems.
- In case of CxScreen < CxPanel, now the screen will zoom to full panel size.
- Change the value of ESC_SMISAVEREGISTERS & ESC_SMIRESTOREREGISTERS,
  anyone using that escape functions should recompile their codes, when
  using this latest driver.
- Fixed compilation error in debug mode; should use GPE_ZONE_WARNING 
  instead of GPE_ZONE_WARN for CE4.2.

RC-3 Release (0.03.10)
- Disabled backend video, old vpe programs will not work.
- Added Vsync interrupt support for Front-end video.
- Blocked Reduced and Minimal power modes while in high power consumption modes
  like hardware video.

(0.03.09)
- Added Intel IXP425 support.
- Power Management now will go to full power when it detects hardware video,
  alpha plane or video zoom.
- 8051 and USB are turned off no during the initialization.
- Added I2C_CLOSE API call to close the current I2C session.

(0.03.08)
- Force LCD sync polarities to negative only since TFT panels all take negative 
  sync signals, but CRT takes various sync polarities depend on resolutions.
- Added "DisplayType" registry flag for user to determine which output(s)
  (panel/CRT/panel+CRT) to enable.
- Added I2C API.
- Added support for additional screen resolutions to Power Management.
- Power Management API has changed.
- Added "VgxSysIntr" registry variable that determines the SYSINTR value to use
  for Voyager interrupt handling. If the varibale is not specified, the driver
  will attempt to get the value from OS.

(0.03.07)
- Added 1280x1024 mode, and fine tuned 320x240 TFT panel timing for Sharp LQ057Q3DC02.
- Added "PowerMonitor" registry flag for ReduceOn enable/disable.
- Fixed PDR2656 - no display in 32-bit modes.
- Fixed PDR2664 and PDR2665 - compiling failure.
- Added "#ifdef DD_ENABLE" check for Video API functions so that driver can compile when
  SMI_NODD or SMI_ROTATION environment variables are set.
