- Changes in v1.24:
-
- Fix bug causing "not running in ..." messages if vga_init wasn't called.
- Better structure for driver interface ("DriverSpecs"). Fields other
- than the basic driver functions can be included. Type checking is also
- better. Most drivers haven't been updated for the new return types;
- feel free to send patches. Something might be broken, watch out.
- Better acceleration inferface.
- Fix ARK chiptype detection.
- Untested ARK chip support.
- Largely fixed S3-864 + SDAC support.
- Untested clock/DAC support for the Trio64 in the S3 driver.
- Unlock extended registers when forcing Cirrus in config file.
- Try to avoid Cirrus hardware lock-up when switching certain modes.
- Add "accel" program to test new acceleration interface.
-
- Changes in v1.23: (8 Feb 1994)
-
- ET4000/W32 tweaks.
- Added gl_allocatecontext. Use this instead of declaring GraphicsContext
- variables statically. Demo programs changed accordingly.
- Safer VC switching with blits.
- Allow Cirrus SVGA modes with 512K memory.
- Possible Cirrus 5422 MCLK detection fix.
- Incorporate ATI 'driver' from Scott Heavner (allows VGA with 132-column
- textmode).
- Untested ARK driver and untested generic S3 support (640x480x256 @ 60 Hz).
- Unused acceleration interface sketch (accel.h/cirrus.c).
-
- Changes in v1.22:
-
- ET4000 additions for STG170x DAC (tseng3.c and driver), linear addressing
- support for W32p, better general linear addressing handling with new driver
- function, 8-bit color components CLUT support for AT&T DAC (David
- Etherton).
- Cirrus driver tweaks.
- S3 driver rewritten for S3-864 + SDAC (doesn't work yet) using new
- interface.
- Linear addressing probing with vga_setlinearaddressing. Console switching
- is not a good idea with linear addressing enabled.
- Treat Oak 077 as standard VGA (incompatible with OTI-087 mode dumps).
- Fix planar getpixel (untested).
- VC switching in RAW keyboard mode (e.g. Doom) (doesn't always work,
- function keys seem to return different scancodes at different times).
-
- 'VGAGL' status:
- Should be usable seperate from svgalib with minor changes.
- GraphicsContext should be allocated dynamically (malloc)
- by library for compatibility/extensibility.
- Non-expanded font text write functions added (untested...).
- Missing is proper direct page flipping support (double-buffering
- in video memory). This would require all operations to be
- performanced at a certain offset into the framebuffer.
-
- Changes in v1.21: (23 Dec 94)
-
- Partially restructured Cirrus driving using clean, XFree86-style
- SVGA-generalized interface. Check out timing.*, vgaregs.* and cirrus.c.
- Cirrus driver itself should now support all 542x/543x cards.
- Fix MouseSystems movement overflow.
- Fix PS/2 mouse support finally (sorry).
- Fix (old) Logitech protocol mouse handling (hopefully - I lost the
- message that contained the fix).
- Fix Cirrus bitblt bug.
- gvga6400 driver BIOS check changed; munmap seems to mess things up.
- Add vga_getpixel() (untested).
- Incorporate restorepalette patch from Charles Blake, allows custom
- textmode console colors (see utils/README).
-
- Changes from Michael Weller:
- Made GSVGAMODE parsing case insensitive, and added names for 16M32 modes.
- vgatest displays info about 16M32 modes better.
- mach32 - Support for 8bit clut on type 2 DACS.
- Added testaccel demo.
- mach32 - Support for all accelerator functions.
- Added vga_hlinelist(), vga_blitwait(), vga_ext_set(), [vga_accel()]
- mach32 - eeprom interpretation more robust and configurable for stupid AST
- boards.
- mach32 - changed 16M4 -> 16M32 for compatibility
- Fix: reserve memory for one screen on EACH setmode call (as the README
- states).
- mach32 - Added support for AST style EEPROM checksums.
- Added commands to control RTS/DTR lines for multiprotocol mice.
- Fix: mach32 - VGA modes should work now even in 132 columns text modes.
- Sanity check for MAX_REGS in vga.c
- Fix: Raised MAX_REGS as was actually needed.
- Fix: Textmode utils now give errors on problems with accessing files.
- Fix: Restore of Mach32 regs after clock probe was broken (cosmetic, no
- problems reported).
- Fix: Mach32 Dac1&4 have to use double/triple clocks in 16/24bpp.
-
-
- Changes in v1.20: (25 Nov 94)
-
- Clean up VT code a bit.
- Slight ET4000/W32p detection fix.
- Possible mach32 32bpp copyscreen fix.
- Allow VT-switching with mouse support (it was disabled because of
- interaction with an old version of selection, I take it things are
- better now?).
- Preliminary Cirrus 5434 support (untested, only 1280x1024x256 for now),
- will be fixed soon.
- New Oak driver (Christopher Wiles).
- Use seteuid instead of setuid to give up setuid-root permissions.
- Hack that may fix 132-column textmode/VGA mode problems on ET4000.
- Fix color/mono config option (mono was broken).
- Disable 320x200x256 page flipping for ET4000.
- Fix Cirrus fillblt register corruption problem.
- GVGA6400 driver (Arno Schaefer).
- vga_init now returns -1 if not on a suitable console (0 otherwise); hard
- exit can only happen in vga_setmode (David Liu). This should help
- programs with multiple output devices like gnuplot.
- Added mouse_init_return_fd and keyboard_init_return_fd for select() use.
- Add SIGKILL catch to raw keyboard interface.
- PS/2 mouse support possibly fixed.
- Shared library 1.2.0 (corresponds with main svgalib version number).
-
-
- Changes in v1.12: (17 June 1994)
-
- Delay console checking until actually setting a mode (should fix problems
- with device-probing programs like gnuplot).
- Fix planar mode getmodeinfo bug for Trident and others (should fix floating
- point exceptions in zgv).
- Support PS/2 mouse in config file.
- Fix one-byte-per-pixel gl_putboxmask.
- Shared library 1.1.8.
-
- Changes in v1.11: (19 May 94).
-
- Better fix for ET4000/W32 auto-detection.
- Fix typo that prevented ET3000 auto-detection.
- Clipping bug with compiled bitmaps fixed.
- Shared library 1.1.7.
-
- Changes in v1.10: (9 May 94)
-
- Possible fix for ET4000/W32 auto-detection (does iopl(3) now).
- Logitech mouse fix.
- Repeated keyboard_init/keyboard_close fix.
- vgagl fixes for mach32 'misordered' 32bpp truecolor and 32bpp paged fillbox.
- mach32 - Forgot to disable write mask for VGA framebuffer (zgv2.2 screen
- corruption after online help)
- mach32 - Wrong assumption about BIOS enabling the mem aperture.. was actually
- done by Xfree.. driver will setup linear framebuffer itself using
- info from the EEPROM now.
- mach32 - added mach32/mach32.std-modes info file..
- mach32 - ran a spell checker over my README's to throw away the worst errors.
- mach32 - Patched vgapix for correct RGB_MISORDERED support.
- mach32 - This needed an additional global for the modeinfo-flags (short cut is MODEFLAGS).
- mach32 - Changed blankadjust for 32bpp modes and DAC-type 2.
- mach32 - Patched mach32 autodetection code.
- mach32 - Changed 32bpp setting at all by defining a new dacmode (needed for dac-types 5)
- mach32 - Changed VFIFO handling and vfifo defaults for 16/24/32bpp modes.
- mach32 - Added fuzz factor of 0.5KHz when obeying monitor horz restriction.
- mach32 - deleted dacwidth config command (was not useful)
- mach32 - Added setuplinear command for mach32 (would be useful for cirrus too)
- mach32 - Changed order of restore of extended ati registers to obey locking..
- may need even more fixing..that is ensure restore of vgaregs before they are locked
- again when restoring extended ATI lock registers.
- mach32 - Had to change order of entries in save-/setregs array for mach32 for this.
- Shared library v1.1.6.
-
- Changes in v1.09: (2 May 94)
-
- Significant mach32 driver/docs update (potentially dangerous bug fixed).
- Some vga_draw primitives now support 32-bit pixel modes (better support is
- in vgagl).
- Cirrus 320x200x256 registers redefined to support page flipping (setmodeX
- doesn't work anymore).
- Trident 320x200x256 page-flipping disabled.
- Shared library 1.1.5.
-
- Changes in v1.08: (27 Apr 94)
-
- Improved vgagl 24-bit physical/32-bit virtual screen support (pageflipping
- really fixed, speed increase (alignment)).
- S3 driver hacked (try it if you are bold).
- Sierra 15025/26 DAC support should work for 32K modes now.
- Added PS/2 mouse support (untested).
- More vgagl 32bpp primitives.
- 320x200x256 vgagl page flipping fix (this is a big one).
- Added ctrl-c detection to low-level keyboard interface.
- vgagl copyboxfromcontext added, and more efficient copyboxtocontext.
- Shared library 1.1.4.
-
- Changes in v1.07: (19 Apr 94)
-
- Moved main library source into src/. Cleaned up shared library making.
- Fix permissions of utils/convfont.
- Fix tty behaviour:
- Open /dev/tty instead of /dev/tty0 (previously non-root users could not run
- programs if /dev/tty0 was not world-readable, like in the recent slackware).
- Don't kill the terminal settings when detecting a non-graphics capable
- virtual console (stupid bug related to use of atexit()).
- Limited support for ioperm(1) by Olaf Titz. Allows non-root users to run
- svgalib binaries which are not setuid-root.
- Emulated paged copybox in vgagl (untested).
- Utility to read out the ATI mach32 EEPROM.
- Shared library 1.1.3.
-
- Changes in v1.06: (11 Apr 94)
-
- vgagl pageflipping fix for 24-bit/32-bit virtual screen.
- Fix 16 color mode availability on ATI mach32.
- Possible ET4000/W32 Sierra 15025/26 64K color fix.
- vgagl compiled bitmaps enhanced (not completely compatible with v1.05),
- but still untested.
- Possible Trident 320x200 page flipping fix.
- Shared library 1.1.2
-
- Changes in v1.05: (2 Apr 94)
-
- Some unfinished SVPMI stuff (feedback strongly encouraged).
- Added vgagl compiled bitmap functions (256 color only, untested).
- Added definitions for 32 bits per pixel truecolor modes (not used yet). I
- don't feel like adding vga_draw* functions for these; use vgagl.
- vgagl now supports VGA 16 color modes indirectly.
- Added RAW mode keyboard interface (vgakeyboard.h).
- Mouse driver fix.
- Shared library 1.1.1.
-
- Changes in v1.04: (29 Mar 94)
-
- Support for more than 1Mbyte of memory on ET4000W32i/W32p and 24-bit Sierra
- DAC (15025/6) (untested). Fixed copying 4 bytes per pixel virtual screen to
- three bytes per pixel screen (e.g. '3d' in truecolor modes). Fixed missing
- gl_enablepageflipping. Fixed Cirrus linear addressing.
- Amazing alpha ATI mach32 driver by Michael Weller; configuration file format
- extended.
- Shared library version 1.1.
-
- Changes in v1.03:
-
- EGA support fixed (Kapil Paranjabe). Added vga_safety_fork.
- utils/Makefile fixed.
-
- Changes in v1.02:
-
- vgagl bitmap scaling improved. vga_lockvc/unlockvc should be useful now to
- avoid corruption of certain VGA registers used for drawing.
-
- Changes in v1.01:
-
- Fixed copying to planar 256 color mode in vgagl, and added page flipping
- support. Setting an SVGA mode after a planar 256 color mode clears the
- screen properly now. Shared library 1.0.10.
-
- Changes in v1.00: (Jan 94)
-
- [The version number doesn't say anything about stability/completeness etc.]
- A number of bug fixes related to Mode X (display start, console switching,
- planar 320x200x256 allowed with vga_setmodeX()).
- Added vga_copytoplanar256 for Mode X-like modes. Added smooth scrolling demo
- program. Demo programs moved to demos/.
- Cirrus linear addressing works (if you have less than 16Mb of memory); see
- demos/testlinear. Added ET3000 driver. Trident 8900 reboot-beep problem should
- be fixed.
- Shared library 1.0.9
-
- Changes in v0.99:
-
- ET4000 patches by Hartmut Schirmer: ET4000 register dumps now have extra
- registers, so old register dumps won't work; register dump program (tseng3,
- moved to et4000/ directory) supports VESA modes. Microsoft mouse handling
- bug fixed. Shared library 1.0.8.
-
- Changes in v0.98:
-
- Some minor bugfixes, low-level mouse handling rewritten (was very slow).
- Added vga_runinbackground and vga_oktowrite as a kludge to allow a graphics
- program to run in the background (not entirely safe). Disabled ET4000 clock
- detection (wasn't used yet).
- Shared library version 1.0.7.
-
- Changes in v0.97:
-
- Fixed Cirrus 1024x768x256 non-interlaced. Other modes use default (lowest)
- frequencies. Fixed bad virtual screen bug in vgagl (copyscreen).
- Incorporates patches from Hartmut Schirmer (et4000 clock frequency
- determination). Shared library 1.0.6.
-
- Changes in v0.96:
-
- Corrected et4000/et4000.default. Cirrus 1024x768x256 non-interlaced.
- Hopefully fixed Cirrus monitor settings. Cirrus blitting works again. Fixes
- in vgagl truecolor framebuffer support. Shared library 1.0.5.
-
- Changes in v0.95:
-
- Avoid writing to some reserved registers on ET4000 and Trident (fixes dual
- monitor setups) (David Monro). Cirrus 1024x768x256 was doing scary things if
- the svgalib monitor type was set to allow non-interlaced. Added Cirrus
- 1024x768x16 non-interlaced and 1280x1024x16 interlaced. Shared library
- 1.0.4.
-
- Changes in v0.94:
-
- Added 132x43 textmode tweaking utility. Put utilities in utils/.
- restoretextmode was not saving/restoring extended registers anymore. Shared
- library 1.0.3. Hack to prevent standard VGA modes from failing to work after
- having run XFree86 on Cirrus. gl_setcontextwidth fixed.
-
- Changes in v0.93:
-
- Oops, version 0.92 was not quite up to date. Shared library is 1.0.2. We'll
- get libvga.so.1.0.99 before the end of the year at this rate :-).
- gl_copybox truly fixed.
-
- Changes in v0.92:
-
- Fixed broken configuration file reading; some minor changes.
- Shared library is now version 1.0.1. Source is flawed.
-
- Changes in v0.91:
-
- Various fixes. Dumpreg should work better in X now. The default dynamically
- defined ET4000 registers are now in /usr/local/lib/libvga.et4000.
- Added vga_getgraphmem.
- Shared library support (requires tools 2.8 to build). This greatly reduces
- executable size and is good for binary compatibility.
- __svgalib_graph_mem is now shadowed in a read-only user-visible global
- variable (graph_mem) for easier shared library building.
- Fixed console switching bug when a textmode is set in between the setting
- of graphics modes.
-
- Oak 640x480x256 should work now.
-
- vgalgl updates. Added 4 bytes per pixel virtual screen support.
-
- Added vga_init. This will detect and initialize the driver, and give up
- supervisor rights, having obtained I/O permissions. This is the recommended
- first line of any program that uses svgalib.
-
- Should do chmod a+s on restorefont.
-
- EGA support from egalib by Kapil Paranjabe integrated into svgalib. This
- is currently untested.
-
- Mouse support (can also be used independently). Added vga_lockvc and
- vga_unlockvc; vga_getkey (read keyboard without waiting). Using the mouse
- means no console switching for now.
-
- Initial untested S3 driver. Goal is to provide support for truecolor modes
- on the 801/805/928, in SVGA mode. Properly uses monitor type variable.
- [doesn't work]
-
- Configuration file for mouse/monitor type. Monitor type not used by drivers
- yet, except Cirrus.
-
-
- Changes in v0.9:
-
- Extensive changes and restructuring, by Hartmut Schirmer. Dynamic
- (run-time) register loading from a configuration file for ET4000 cards,
- providing binary compatibility. High resolution 16-color modes (for ET4000
- at least). More stable virtual console switching.
-
- copybox, and gl_setpalettecolor bugs fixed in vgagl.
-
- Fixed setting of standard VGA mode after SVGA mode.
-
-
- Changes in v0.82:
-
- Virtual console switching cleanup.
-
- The dumpreg program now also shows extended registers.
-
- Added Oak driver, but extended registers have not been filled in. Somebody
- should run XFree86 with the Oak driver, dump the extended registers with the
- dumpreg program (make sure the Oak driver is enabled in config.h), and put
- them in oak.c. With some luck it'll work.
-
-
- Changes in v0.81:
-
- Restorefont (write option) was broken again due to bug in vga.c; gl/text.c
- was missing in v0.8. Added vga_disabledriverreport.
-
-
- Changes in v0.8:
-
- Fixed major bug in vga_getmodeinfo in vgadrv.c. This may have caused
- spic to fail on unsupported SVGA cards in 320x200x256.
-
- vga.c split, and other changes (Hartmut Schirmer). Note that mode numbers
- beyond 1024x768x256 have changed. Standard VGA modes 720x350x16 and
- 720x480x16 added.
-
- Virtual console switching improved (bank/linewidth/displaystart preserved).
-
-
- Changes in v0.7:
-
- Trident textmode restoration and SVGA modes should work now on 1M cards
- (thanks to Scott Heavner).
-
- Bug fixes in vgagl.
-
-
- Changes in v0.6:
-
- Trident driver bug fixed; detection cleaned up. 800x600 and 1024x768 on 1Mb
- cards don't work correctly.
-
- Added Cirrus 800x600x16M NI (at 50 Hz), and program to set the Cirrus memory
- clock to a higher value (setmclk.c).
-
- Added framebuffer graphics library for one, two and three byte-per-pixel
- modes. Documentation improved.
-
- vga_setrgbcolor added.
-
- ET4000 Hicolor fixes (thanks to Savio Lam), and other fixes (Scott Heavner).
-
-
- Changes in v0.5:
-
- Fixed palette register timing bug (caused occasional corruption of textmode
- palette).
-
- Added function that checks the environment variable GSVGAMODE for a
- default mode (vga_getdefaultmode). The environment string can either be a
- mode number (compatible with VGAlib Ghostscript), or a mode name as
- in (G640x480x2, G640x480x16, G640x480x256, G640x480x32K, G640x480x64K,
- G640x480x16M, PROMPT (ignore)).
-
-
- Changes in v0.4:
-
- restorefont.c as distributed in v0.3 missed a case line in a switch
- statement which made it useless.
-
- Each VGA register write in the library was producing silly debugging code
- (I forgot to restore the macro definition), making everything significantly
- larger than neccessary.
-
- Added vga_getchipset function. vgatest now only lists modes that are
- available.
-
- The ET4000 driver has been improved, including Hicolor DAC detection
- (thanks to David Monro and Daniel Jackson).
-
- Cirrus driver:
- Fixed 5420/2/4 bug, cleaned up detection, changed the 800x600 timings, and
- added missing modes 1024x768x256/32K/64K, as well as 320x200x15/16/24bit.
- Also, there's support for some of the accelerated features of the Cirrus
- 5426, the driver provides bitblt (move box), fillblt (fill box), and
- imageblt (write bitmap from system memory) functions.
-
- Display start address can now be meaningfully changed in 16-color and planar
- 256 color VGA modes for page-flipping (address is expressed as number of
- pixels).
-
- Fixed the vga_flip() functionality; if you press escape during
- vga_getch() the console is switched to textmode until another key is
- pressed. [note: this has been obsoleted by console switching]
- The default amount of video memory saved in SVGA modes is the size
- of one screen. If the program uses more (if it uses page-flipping, for
- example), you must indicate it with the vga_claimvideomemory function. This
- prevents 2048 or 1024K being saved when only a few hundred K is required.
-
- svgalib now waits until the virtual console it is running in becomes active
- before setting the first graphics mode.
-
- Implemented transparent virtual console switching (which uses vga_flip).
-
-
