- cgxsystem.library
- =================
-
- Changes for 41.22
-
- - A datatypes.library >= v44 is not patched by CyberGraphX anymore
- - graphics/BitmapScale() did not work properly for 24bit 3BPP CyberGraphX
- maps (e.g. corrupt graphics with Voyager 2.x/3.x on 24bit packed pixel
- screens)
- - CyberGraphX's OpenScreenTagList() patch now passes the SA_Pens tag
- to intuition even if a workbench type screen is to be opened. This
- fixes the problem that ScalOs assigned system pens were ignored before.
- - added an additional WaitBlit() after chip->chip bitblits to avoid problems
- with slow amiga blitter
- - fixed a "crawling ants" problem in the line drawing code if someone tried
- to draw a patterned line with only one pixel length
- - BltBitmap[RastPort]() & ClipBlit() with minterm 0x6x (src EOR dst) now really
- do a src EOR dst operation instead of swapping src and dst bits on extended
- chunky maps. This fixes some problems with Iconian's popup gadgets on
- high/truecolour screens for example
- - fixed some problems with doublebuffering. ChangeVPBitMap() patch did not
- clear the FASTOBTAIN driver flag (MANDATORY)
-
- Changes for 41.21
-
- - the patch that should speed standard wb pattern backfills is now optional.
- It was added in 41.12 (r69a archive). Since it could interfere with some
- hacks widely spread, it is disabled by default now. It can be enabled by
- setting env:cybergraphx/WBPATSPEEDUP to 1
- - bumped cybergraphics.library version to 41.6
- - bitmaps for intuition screens are cleared again (modified in 41.20) before
- they are attached to the screen since some programs rely on that behaviour
-
- Changes for 41.20
-
- - bitmaps for intuition screens are not cleared anymore before they are
- attached to the screen
- - software line drawing code should now produce the same line for every
- color depth
- - fixed a bug in planar BltPattern() complement mode with mask
- replacement which e.g. fixes the crashes with TypeSmith's glyph
- filling option
- - fixed bug in WriteLUTPixelArray()/cybergraphics. Format 0 now works
- properly
- - bumped cybergraphics.library version to 41.4
-
- Changes for 41.19 (r70a archive)
-
- - added support for boundary aligned CyberGraphX bitmaps (e.g. required by
- Fusion)
- - added new feature. If the mode you selected in ScreenMode prefs is not
- available when the Workbench screen is opened, CyberGraphX tries to
- find a replacement mode. If wb width and height were set to default
- mode dimensions, it uses a width of 640 and height of 480 by default.
- - fixed a bug in the BltBitmap()/graphics minterm 0xc0 planar->planar
- code introduced in 41.18. blits with a width less than 32 did not work
- when both source and dest x were on a 32 pixel boundary
- - added coordinate sanity checks to CyberGraphX's graphics.library/Draw()
- function since programs like VisualPrefs seem to call it with invalid
- (negative) coordinates which caused memory havoc in certain cases.
-
- ADDITIONAL NOTE: Some people reported that increasing stack size of the
- initial shell fixes certain boot problems. Try to add a stack command
- in the startup-sequence to check if it fixes anything.
- Also, there seems to be mount related problem with certain drivers that
- causes some systems to halt at boot time.
- The c:mount command does enforcer hits when there is no tooltype set
- for .info files in devs:dosdrivers. Unfortunately this can lead to a
- total system deadlock in certain cases. The AHI audio driver for example
- does not have ACTIVATE=(0|1) in its .info file and mounting it causes hits
- in most cases.
- Please fix it and check if booting the system works again without problems
- in case of any trouble.
-
- Changes for 41.18 (r70/PPC-CD archive)
-
- - minor changes for the CGX AGA release
-
- Changes for 41.17 (r69f archive)
-
- - fixed a long outstanding bug in the display mode installation code for
- OS 3.1. This bug could lead to loss of AGA/ECS mode monitor IDs when
- multiple graphics cards were installed in the system.
- - cgxsystem.library.ppc now falls back into 040/060 mode if ppc.library
- can not be found.
- - FillPixelArray()/cybergraphics does not trash register D2 anymore when
- rendering to a non layered rastport
-
- ADDITIONAL NOTE: If you experience any problems with cgxsystem.library.ppc
- please try the .040 version first to check if it solves your trouble
- before reporting any bugs.
-
- Changes for 41.16 (r69e archive)
-
- - changed behaviour of custom bitmap support code for OpenScreenTagList()/
- intuition introduced in 41.15. This should fix some problems with programs
- like Resource or CyberView which pass a custom bitmap to OpenScreenTagList()
- - added CyberGraphX support for AllocScreenBuffer()/ChangeScreenBuffer()/
- FreeScreenBuffer() intuition calls
- - GetBitMapAttr(bm,BMA_FLAGS)/graphics now sets the BMF_DISPLAYABLE flag
- for CyberGraphX displayable bitmaps
- - fixed some problems in DrawEllipse()/graphics with overlapping pixels in
- complement drawing mode
- - OpenScreenTagList()/intuition cleared the SA_ErrorCode long field in some
- cases although the screen was not opened properly. (-> e.g. CygnusED's
- Spawn new CED option never opened a new screen but a window because it
- always got an errorcode of 0)
- - OpenScreenTagList()/intuition now uses the width/height parameters of the
- NewScreen structure instead of ignoring it and using the default dimensions.
- - The mouse pointer should not jump around anymore if someone tries to drag a
- non draggable screen (if driver has dragging disabled). Fix requires latest
- drivers also
- - fixed an enforcer hit problem that occured in conjunction with the SysLock
- utility
-
- Changes for 41.15 (r69d archive)
-
- - hopefully fixes the crash problems introduced in r69c
- - removed some debug output in the DoCDrawMethodTags()/cybergraphics call
- which was in r69c/41.14
-
- Changes for 41.14 (r69c archive)
-
- - There is now a special ppc version of cgxsystem.library included. Please use
- that if you have a ppc accelerator card.
- - flood fill algorithm replaced by a faster version which leads to faster icon
- redrawing in certain cases
-
-
- cgxvideo.library
- ================
-
- Changes for 41.12
-
- - If no taglist was passed to AttachVLayerTagList(), the window inner
- offset was never added to the video layer (e.g. fixed problem
- with WebVision up to version 2.1. The overlay always covered the
- whole window)
-
- Changes for 41.11
-
- - Some corrections in the autodocs
- - UnlockVLayer() has been renamed to UnLockVLayer()
- - Source formats SRCFMT_RGB15 and SRCFMT_RGB16 have been renamed to
- SRCFMT_RGB15PC and SRCFMT_RGB16PC, respectively. If you recompile your
- code with the new includes you have to modify your sources slightly.
- - fixed a typo bug in the pragmas file, SetVLayerAttrTagList was spelled
- SetVlayerAttrTagList there.
-
- Changes for 41.10 (r69 archive)
-
- - removed all CVision3D hardware dependencies. Instead it uses a generic CGX3
- driver VStream API now. Make sure you have the latest drivers installed when
- you use this library.
-
- - added support for GIMMEZEROZERO windows
-
- Changes for 41.8 (r67 archive)
-
- - minor internal changes
-
- Changes for 41.7 (r64 archive)
-
- - added new source types SRCFMT_RGB15 and SRCFMT_RGB16 to allow for rgb
- color space overlays
-
- Changes for 41.6 (r63 archive)
-
- - added new tag VOA_UseBackFill to allow for automatic backfill of simple
- refresh layers when the color keying option is used.
-
- Changes for 41.5 (r58 archive)
-
- - cgxvideo.library does not allow to create overlay on interlace screens
- anymore
- - Fixed problem with wrong mousepointer colours when overlay was enabled.
- This fix requires at least CVision3D driver V2.2
- - fixed a bug with 15/16/24 bit opaque overlays
- - added color keying support.
- - New tag VOA_UseColorKey for CreateVLayerHandleTags() call added
- - New tags VOA_ColorKeyPen and VOA_ColorKey for GetVLayerAttr() call
- added
-
-

- ================
-
- Changes for 41.7 (r69 archive)
-
- - fixed a mismatched free mem size in image decoder
-
- Changes for 41.6 (r58 archive)
-
- - library now correctly supports library expunge which safes some memory
- after system boot.
-
- Changes for 41.5 (r56 archive)
-
- - initial public release
-
-
- CV64 driver
- ===========
-
- Changes for 2.10 (r70a archive)
-
- - The driver added an additional, faulty screenmode to the mode list in some
- weird cases. Now fixed
- - Fixed an illegal memory access in the acceleration code for patterned mask
- fills (e.g. used by colorwheel gadget)
- - If the BOOTLOGO is enabled the driver now automatically switches to Amiga
- video again after the logo is displayed for 8 seconds (requires that CV64
- VGA input is connected to amiga video output of course). You had to use
- LAMIGA-m after 8 seconds manually before to switch to the amiga video.
- - added support for boundary aligned video maps in DRAGGING=OFF mode
- (e.g. required by Fusion). Requires at least cgxsystem.library 41.19
-
- Changes for 2.9 (r69f archive)
-
- - modified MOVE16 bitmap swap in/out code to workaround a bug in certain
- 040 accelerator cards.
- - fixed a potential race condition when an interrupt occured, the int handler
- was already installed but the hardware was not initialized completely.
- - (YES|NO) is also accepted for the BOOTLOGO tooltype now instead of (1|0)
- - reenabled roxxler support. There is now an additional tooltype
- USEROXXLER=(YES|NO) to disable roxxler manually. Default is enabled.
-
- Changes for 2.8 (r69e archive)
-
- - added os3 style doublebuffer support. Only works with dragging disabled
- (tooltype DRAGGING=NO), otherwise any attempt to allocate a dbufinfo will
- fail. Requires at least cgxsystem.library 41.16
-
- Changes for 2.7 (r69c archive)
-
- - the driver does not crash with divide by zero anymore at startup if modes
- with pixelfrequencies less than 12.5 mhz or higher than 135mhz are loaded
-
- Changes for 2.6 (r69 archive)
-
- - added bitblit acceleration for some occasionally used minterms
- - added 2 new driver calls
- - fixed a problem in the bitmap swap code for interleaved bitmaps <= 16 cols
- - the memory management code now uses a first in/first out mechanism for
- bitmaps
- - fixed a bug in the memory management code that only occured while mungwall
- was running
- - driver recompiled with SAS/C 6.58 and global optimizer enabled
- - modified init code to workaround a bug of certain boards (int level is set
- to 6 although it is programmed to 2 which could lead to lockups at startup).
- - fixed a bug in patterned masked fill acceleration code for rgb screens
- that was introduced in 2.5 (fixes a problem with colorwheel on rgb screens)
-
-
-
- CV3D driver
- ===========
-
- Changes for 2.17 (r71 archive)
-
- - modified driver init code to fix some problems at startup
- - Due to a SAS/C optimizer bug, the init code did a byte write to a
- derefenced address which is probably the reason that the latest CVision3D
- driver did not work for many people.
-
- Changes for 2.16 (r70a archive)
-
- - The driver added an additional, faulty screenmode to the mode list in some
- weird cases. Now fixed
- - If the BOOTLOGO is enabled the driver now automatically switches to Amiga
- video again after the logo is displayed for 8 seconds (of course requires
- cv3d scandoubler output). You had to use LAMIGA-m after 8 seconds manually
- before to switch to the amiga video.
- - added support for boundary aligned video maps in DRAGGING=OFF mode
- (e.g. required by Fusion). Requires at least cgxsystem.library 41.19
-
- Changes for 2.15 (r69f archive)
-
- - modified MOVE16 bitmap swap in/out code to workaround a bug in certain
- 040 accelerator cards
- - fixed a potential race condition when an interrupt occured, the int handler
- was already installed but the hardware was not initialized completely.
- - reenables draggable screens again that were accidentally disabled in 2.14
- even if tooltype DRAGGING was set to "YES"
- - fixed a bug in the PLL table code introduced in r67 (v2.10). display modes
- that were defined with a pixelclock > 121MHz always used a maximum pixelclock
- of 121MHz really
- - (YES|NO) is also accepted for the BOOTLOGO tooltype now instead of (1|0)
-
- Changes for 2.14 (r69e archive)
-
- - added os3 style doublebuffer support. Only works with dragging disabled
- (tooltype DRAGGING=NO), otherwise any attempt to allocate a dbufinfo will
- fail. Requires at least cgxsystem.library 41.16
- - Overlay in 15bit rgb modes enabled RGB16 for the primary stream. Now the
- colours are correct for 15bit overlay screens
-
- Changes for 2.13 (r69c archive)
-
- - added new tooltype called MULTIMEDIAMEM=(YES|NO) which enables/disables
- the multimedia extensions like video overlay and 3d. If disabled, extension
- memory is used as extra video memory for amiga bitmaps/screens.
-
- Changes for 2.12 (r69 archive)
-
- - added bitblit acceleration for some occasionally used minterms
- - added support for generic CGX3 driver video stream API. cgxvideo.library 41.10
- uses the new interface.
- - removed an obsolete debug output that could appear with a certain interrupt
- state
- - added 2 new driver calls
- - fixed a problem in the bitmap swap code for interleaved bitmaps <= 16 cols
- - The version string of the driver now gives info on the zorro version it
- is compiled for instead of the cpu version
- - the memory management code now uses a first in/first out mechanism for
- bitmaps
- - fixed a bug in the memory management code that only occured while mungwall
- was running
- - driver recompiled with SAS/C 6.58 and global optimizer enabled (only for Z3
- version)
-
-
- Cirrus Logic drivers
- ====================
-
- Cirrus 2.8 (r70b archive)
-
- - hardware crsr y position is set properly now for non interlaced vertical
- resolutions >= 1024
- - Due to a bug in the PLL Pixelclock table, PiccoSD64, PicassoIV and
- and Inferno never used a pixel clock > 100 Mhz
- - unfortunately maximum pixelclock for PicassoIV and Inferno was limited to
- 90MHz in 8Bit modes due to a driver bug, it now goes up to 135MHz again
- - The PiccoSD64, PicassoIV and Inferno driver now properly uses double clock
- mode when an 8bit mode with a pixelclock > 85 Mhz is selected
-
- Cirrus 2.7 (r70a archive)
-
- - The driver added an additional, faulty screenmode to the mode list in some
- weird cases. Now fixed
- - added support for boundary aligned video maps in DRAGGING=OFF mode
- (e.g. required by Fusion). Requires at least cgxsystem.library 41.19
- - The PicassoIV driver does not try to enable the flickerfixer anymore
- if the tooltype PASSTHROUGH is set to NO
-
- Cirrus 2.6 (r69f archive)
-
- - modified MOVE16 bitmap swap in/out code to workaround a bug in certain
- 040 accelerator cards.
- - reenabled DPMS support functionality for PicassoII,Spectrum,PiccoloZ2/Z3
- cards egain
- - PiccoSD64/Piccolo 15/16bit<->8bit format conversions were incorrect for
- dragged screens. Fixed
- - (YES|NO) is also accepted for the BOOTLOGO tooltype now instead of (1|0)
- - fixed some PIV flickerfixer related problems
-
- ADDITIONAL NOTE: Starting with r69e, a PicassoIV driver is included although
- it was originally planned to be released with the r70 archive. This driver
- is not 100% in some respects although it should work ok for most stuff. It
- has been included to show that this driver is neither a hoax, nor that it is
- "phase5 tactics" to delay the driver and release r69a-zz archives until r70
- is out. Keep in mind that CGX3 is a freebie and so is the PIV driver.
- Development of the driver has been and is actually in no way supported by
- VillageTronic. If you don't feel comfortable with the driver, don't use it.
- Bug reports are appreciated nevertheless.
-
- KNOWN PROBLEMS: With CGX3, some PicassoII users reported strange "fuzzy" pixel
- problems when displaying fonts on 15/16 bit screens. Since this only happens
- on certain cards, its very hard to reproduce and to track down. We hope to
- fix it in a future release.
-
- Cirrus 2.5 (r69e archive)
-
- - added os3 style doublebuffer support. Only works with dragging disabled
- (tooltype DRAGGING=NO), otherwise any attempt to allocate a dbufinfo will
- fail. Requires at least cgxsystem.library 41.16
- - added real vblank int support for PicassoIV (needs at least p4resource v2)
- - bootlogo should show up now if enabled for Spectrum/PicassoII(+)/Piccolo
- cards
- - PASSTHROUGH tooltype now works for Spectrum/PicassoII(+)/Piccolo cards
- - hopefully fixed remaining masking problems for template blits in 8bit
- modes with PicassoII(+)/Spectrum/Piccolo cards (e.g. FinalWriter toolbar
- was displayed wrong in 2-128 colours)
-
- Cirrus 2.4 (r69 archive)
-
- - init code now correctly initializes the DrvrName field in the GraphDev
- structure
- - vga switch did not switch into passthrough mode when control was given
- over to another graphics card installed into the system. Now fixed.
- - disabled DPMS functionality for PicassoII,Spectrum,Piccolo Z2/Z3 because
- this cards don't support DPMS really.
- - fixed 24bit modes software cursor invisible bug when screen dragging was
- disabled
- - 24bit modes for Cirrus GD5446 cards work now. It seems that the 32bit
- Mac alike modes don't work due to a Cirrus hardware bug.
- - The CGXMode hidden mode flag is now supported by the driver
- - added 2 new driver calls
- - fixed a problem in the dragging code
- - added DRAGGING=(YES|NO) tooltype
- - the display is blanked now if a new view is loaded
- - added PicassoIV support
-
- ADDITIONAL NOTE: Beginning with the PicassoII driver in release 68 people
- reported strange problems. Some people had distorted fonts in 16bit, some
- only had 2/3 of the screen displayed horizontally and some missed complete
- menu strips. Actually only a few people reported that, so we assume that
- it only happens with certain PicassoII cards. As we don't know how to fix
- that problem (it works fine with the PicassoII we have) we need your help.
- If you experience such problems, please mail some more detailed information
- (PicassoII board revision, chip id revision, os version, resolution used
- etc.) to cybergfx.bugs@vgr.com so that the problem can hopefully be fixed
- in a forthcoming release.
