Update revision history for archive rev 69
cgxsystem.library
=================
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
Changes for 41.13 (r69b archive)
- If AllocBitMap()/graphics is called with the SPECIALFMT flag set, it now
uses the exact depth instead of using the supplied depth parameter.
Calling AllocBitMap() with the wrong depth for a certain pixel format
could lead to all kinds of problems with older versions.
- the 040 version of cgxsystem.library now correctly checks for the
availability of a 68040 CPU and fails to load if it can't be found
- LockBitmapTagList()/cybergraphics now works properly if a certain tag occurs
multiple times
- Fixed some weird clipping problems in 15/16/24 bit modes that were likely to
appear when there was memory installed in ZorroII address space (e.g. ZII
memory cards or A2000 turbo cards).
Changes for 41.12 (r69a archive)
- library recompiled with SAS/C 6.58 and global optimizer enabled
- fixed a BltBitmap()/graphics patch bug for Hi/True color bitmaps. The
expansion code for a single plane did not work properly which caused
problems with DiskSalv's startup window for example.
- fixed some screen open problems with programs like Digita's Organizer
- added 2 new LVOs to cgxsystem.library that handle communication with CGXMode
- modified the patch system to avoid trouble with MCP style hacks
- fixed a bug in the patterned line drawing code for hi/truecolor bitmaps
- another "SUPER" production has made it into CyberGraphX 3.
This time its SUPERGELS, a replacement for the original CyberGraphX GELs
system. It is disabled by default, you have to set
envarc:cybergraphx/SUPERGELS to "1" to enable it.
Make sure you have no tools like PatchControl running in front of the
monitor startup. To allow SuperGels to work, you need to run it after
the monitor startup.
- added a new kludge to fix the ViewByName problems in hi/true color modes.
- added new code to speedup standard wb pattern backfills. Probably interferes
with hacks like FastIPrefs. Please make sure to disable this kind of tools
if you experience any problems.
- fixed a bug in BltMaskBitMapRastPort()/graphics patch. If you used a
interleaved planar bitmap as source the mask modulo was not calculated
the way the original graphics.library function did it.
ADDITIONAL NOTE: Please make sure you put hacks like MCP AFTER the
CyberGraphX system is started into the startup-sequence. Otherwise MCP might
cause trouble. Don't install ObtainGIRPort related patches because they can
lead to semaphore deadlocks under certain conditions
cgxvideo.library
================
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
cgxbootpic.library
================
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 2.9 (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 2.15 (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)
Changes for 2.11 (r68 archive)
- WaitBOVP does not cpu-poll the vblank state anymore to wait for the
vertical blank phase
- The driver adds a resource called cv3dscenic.resource to the system now
to grant applications access to the external scenic/mx2 addon module
- fixed a derefenced pointer problem in the screen dragging code when empty
areas were cleared (could lead to enforcer hits)
- Added new tooltype DRAGGING=(YES|NO). If dragging is disabled it is
possible to keep multiple screens in video memory.
Due to a redesign of some driver internals cgxvideo.library up to version
1.8 and cgx3dvirgin.library up to version 1.5 don't work anymore if
dragging is disabled. This will be fixed in a forthcoming release.
Changes for 2.10 (r67 archive)
- the blitter is used now to save/restore the software crsr background
in double clocked 8bit modes (>100Mhz)
- switching from a high/true color screen to a double clocked (>100MHz)
8bit screen should work without problems now
- The CV3D driver uses a modified PLL table now. This fixes some display
clock problems with certain cards
Cirrus Logic drivers
====================
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.
