November 26th 97
Picasso96 v1.32
|
- emulation libraries and Picasso96API.library now prefer faster cards for BestModeID type functions if more than one is installed
- ScrollVPort() implemented and tested (thanks to James Ceraldi). This should fix problems with CyberAnim, too.
- mask blits using same source and destination format (both bitmaps located in graphics card mem) are done with blitter if available.
- PicassoIV: new pixel clock for PabloIV PAL support added.
- WaitBOVP() and WaitTOF() added again after minor fixes, these were left out accidentally in the 1.31 release
- drivers for the CirrusGD542X boards have been fixed. These were unfortunately partially defective in the 1.31 release.
|
November 03rd 97Picasso96 v1.31
|
- CyberVision64: 2MB memory detection corrected.
- CyberVision64/3D: switching logic of scan doubler module fixed and tested.
- Merlin: fixed bug in IRQ handler causing enforcer hits in some cases.
- PicassoII: hardware IRQ only with PII+ fix.
- Retina BLT Z3:
- init code fixed (card locked up sometimes).
- allowed resolutions corrected.
- inversion and fill operations use the blitter now (in many cases).
- fixed some details and added more zero pointer checks in WaitTOF() and WaitBOVP().
- DIPF_IS_DBUFFER set on all P96 modes to reflect implemented double buffering.
- System2ScreenBlits tooltype added to explicitly allow expansion blits through host cpu accesses.
This may speed up Text(), BltTemplate() and p2c blits but should not be used on systems where bus timeouts occure
too early (FastGary option and some ZorroII implementations). If you experience ragged text output and lockups on
Cirrus based cards you should not use this option.
- fastlayers.library: fixed a bug with BACKDROP windows.
- Picasso96Mode: "memory freed twice" alert and settings merging fixed.
- added french translation to the installer script (thanks to Cédric Quillevere).
|
October 13th 97Picasso96 v1.30
|
- Retina BLT Z3:
- hardware VBlank interrupt supported.
- corrected and checked all possible clocks.
- hardware sprite works in HiColor now
- border problem reduced to one line at the top of the display in chunky modes.
- memory check for 4MB detection (hopefully) corrected.
- corrected a bug when blitting from ARGB to RGBA bitmaps (thanks to Stefan Sommerfeld for reporting this bug).
- implemented WaitTOF() and corrected WaitBOVP(), both functions use the hardware interrupt now when available.
- PicassoIV interrupt handling corrected to allow correct 16bit 44kHz playback with the Concierto sound module during VBlank activity.
- new install script introducing update and uninstallation features.
- Pixel64 and UAE drivers included in distribution and installation.
- corrected double buffer handling of non-visible screens which used to consume all free CPU time.
|
October 07th 97Picasso96 v1.29
|
- added Retina BLT Z3:
- first alpha release!
- hardware sprite in Hi/TrueColor not available yet
- only scrolling is currently accelerated
- DPMS should already work
- chunky screens have one line of border at the top and at the bottom, this seems to be a bug of the NCR
- most pixel clocks untested, do not wonder if the display is not stable in certain modes
- no support for external monitor switches yet
- only tested with 1MB, memory check routine might fail for 4MB boards.
- added CyberVision64/3D:
- first alpha release!
- BltTemplate()/Text() and Planar2Chunky are not accelerated yet
- DPMS should already work
- ZorroII completely untested and might not work at all!!!
- monitor switch could not be tested/implemented yet
- on a ZorroIII Amiga it runs fairly well right now...
- success and bug reports for the new drivers are welcome...
- Merlin: implemented Planar2Chunky blits and hopefully fixed a bug due to a missing WaitBlitter()...
- Picasso96Mode: removed obsolete family stuff and enforcer hits
- semaphore added to avoid crashes if multiple instances of Picasso96Mode, PMTNG or PabloPrefs try to open the
global edit screen simultaneously.
- PicassoIV: improved horizontal panning
- PiccoloSD64: blit routines slightly optimized
|
September 23rd 97Picasso96 v1.28
|
- major speed increase: optimized Text(),
- fixed KickStart 3.0 only bug which could cause system crashes,
- removed potential enforcer hit during swapping of planar screens,
- hardware acceleration for monochrome pattern blits (Cirrus only right now),
- graphics memory caching mode changed with 040 and 060 CPUs (a big thank you to Didier Levet!). This can lead to significant speed ups.
If you want to disable this feature you can set the environment variable ENV:Picasso96/DoNotSetMMU to "Yes",
- OS 3.x compatible double buffering implemented. On boards without hardware interrupt support this is not perfect yet.
|
September 04th 97Picasso96 v1.27
|
- PicassoIV: PIP reacts better on hardware restrictions,
- PicassoIV: max. allowed horizontal resolution adapted. Now screens with
up to 2000 pixels are creatable in Chunky and HiColor,
- fixed a bug within the memory management, which was introduced in 1.26
and caused a lot of trouble (e.g. with NoMemory screens).
|
September 01st 97Picasso96 v1.26
|
- PicassoIV & PiccoloSD64: certain masked blits optimized,
- PicassoIV: bug fixes for the 1.25 init bug,
- PicassoIV: some minor PIP enhancements (corrected occlusion in HiColor),
- CV64: speed back to normal on screens with widths of 640, 800, 1024, 1152, 1280 or 1600 pixels (including panning/autoscroll),
- CV64: bug fix in planar2chunky conversion,
- chunky masked blits speeded up on boards with blitter acceleration,
- Picasso96 can no longer be started if there is a cybergraphics.library present in memory already,
- memory management improved (screens have highest priority now),
- DPMS via cybergraphics interface added (works e.g. with MCP).
|
August 26th 97Picasso96 v1.25
|
- Installer help page works on Hi/TrueColor screens now,
- mask blits (e.g. Locale prefs) work on Hi/TrueColor screens now, too,
- added ENV:Picasso96/DirectColorMask environment variable which enables blitting (especially scrolling)
with a plane mask on Hi/TrueColor screens when set to "Yes". WARNING: if you activate this, shell
scrolling will get terribly slow!,
- PabloII support added to PicassoIV.card.
|
August 19th 97Picasso96 v1.24
|
- corrected checks for maximum BitMap size that may be put to the board,
- CV64: some minor speed improvements, corrected sync polarities and screen clearing,
- changed screen mode name for 8 bit modes for better sorting.
- lots of speed improvements on the Cirrus GD5446 (as used on the PicassoIV),
- finished BltPattern() with masks in Hi/TrueColor (ColorWheel should finally work on all screens as expected).
- PiccoloSD64: improved timing and fixed ZorroII planar2chunky bug,
- mouse sprite speed is now the same for all sprite resolutions,
- detecting of empty software mouse sprites implemented.
|
August 10th 97Picasso96 v1.23
|
- further on-board hardware-blitting support implemented,
- friends to bitmaps already on the board will be allocated on the board,
too, especially clip rects. This in combination with the new on-board
blitting functions can lead to dramatically improved layering operations
if there is enough off-screen memory available on the board. So you
might think twice before spending all board memory for large and/or
TrueColor screens... :-)
- improved management of on-board memory.
- to take advantage of the new features, some S3 driver blitter functions
had to be rewritten and may be a little bit slower now. This also fixes
some potential problems with small screens at the end of the board
memory due to restrictions caused by the way the blitter has to be
programmed and leads to more efficient memory usage,
- fixed rounding and pixel clock slider (edit screen) in Picasso96Mode,
- PiccoloSD64: improved timing and fixed ZorroII planar2chunky bug,
- fixed two color chunky screen layering bug,
- changed naming scheme for screen modes to give more detailed
information on the different modes (limited to 31 characters by the OS).
The display IDs are still the same, so only a few braindead programs
should notice.
|

|
June 01st 97Picasso96 v1.21
|
- fixed bug which resulted in BMF_CLEAR being ignored in various cases,

(Commodore did not adhere to its own programming guidelines there...),
- no normal user should ever be annoyed by debug output again from now on.
|
May 23rd 97Picasso96 v1.20
|
- Direct2Chunky and Direct2Planar blits now work by pen comparsion. At least PowerSnap works with Hi- and TrueColor
screens now...
- fixed AllocBitMap() which did not clear bitmaps in some cases,
- fixed bug in Draw() that did not reset some chip registers on planar displays,
- fixed bug in internal DisplayID handling that could cause lockups,

- problem with Picasso96Mode and PMTNG fixed ("Screen too large...")
- HiRes Mouse Sprites finally available on AGA Amigas
- Picasso96 modes now have Genlock bit set

ENV:Picasso96/AmigaVideo" which may be set to: "15kHz" for standard operation and "31kHz"
for 56kHz audio (with ECS and AGA only). This switch was introduced to prevent damage to monitors like the 1084 when
attached to the standard Amiga video output, default is 15kHz. A suitable preferences tool is available.
- added patch for OpenScreen() to prevent the system from running amok wgen someone tries to open a screen with more
than 256 colors under OS 3.0 (which is a stupid idea anyway)

|
| February 24th 97Picasso96 v1.11 |

|
| February 17th 97Picasso96 v1.10 |
- fixed bug causing scrambled displays when a chunky screen with less than 256 colors was removed from the card,
- removed bugs that prevented e.g. CyberGrab to function with HiColor screens, there are still some problems left,
- fixed software mouse sprite trashing on Picasso96API screens, e.g. FliP96,
- hardware clocks and other restrictions checked better now,
- included workaround for stupid programs who think they'll get a planar one plane BitMap if they pass in a chunky bitmap
as friend_bitmap to AllocBitMap()! Even more, they set the BMF_DISPLAYABLE, too, which is only needed for Screen->
RastPort.BitMap's or RasInfo->BitMap's. Those programmers obviously did never read the autodocs. Sometimes I
could really get mad... This includes programs like WordWorth, TrapFaxView and others. This workaround prevents those
bugs but it is still not the way we would like it... In other words, I strongly discourage such incorrect use of system
functions...
|
