1. Corrected the ATI 1881x clocks for use with the ATI Mach8/32 and VGA Wonder chips. The CPU slowdowns should now be gone.
2. Merged I/O ports common to both the ATI and IBM 8514/A compatible chips where they have identical code (extended behavior is still separate). Code duplication is now less than before.
3. Fixed a general polygon pattern issue in the Mach8/32 affecting calc.exe in Win3.x and other stuff.
4. Mode changes are, once again, changed (ATI and IBM), as close as possible to the real thing without destroying existing resolutions.
5. The 8514/A Vertical Counter has been extended to 0xfff so that it can take 1280x1024 resolutions well offered by the Mach32 as well as a better way to change the IBM/ATI modes through a callback swap where approprietate.
6. in 8514/A mode, reads from the 0x3c6-0x3c9 ramdac range is redirected to the 8514/A RAMDAC (0x2ea-0x2ed).
7. LFB access in the Mach32 now no longer takes account of the SVGA derived rops. Fixes Mach32 display on NeXTSTEP/OPENSTEP 3.x/4.x
8. Reworked the Display Sense Status and Subsystem Status ports so that they're not copycats from MAME and instead follow the datasheet.
Now takes constants with human-readable names instead of
Win32 string table IDs, language.h is no longer needed
ui_msgbox*() no longer accepts string IDs as arguments directly,
plat_get_string() must be explicitly called to retrieve the string
IBM/ATI 8514/A side:
Made mode switches more immediate when actually switching from VGA to 8514/A and viceversa.
Tseng ET4000AX/W32 series side:
Actually use bit 2 of index 0x3f for the horizontal blank start bit 8 instead of bit 4 (horizontal retrace start), fixes skew issues with the et4000w32i rev B. card with resolutions like 1024x768 at 15 or 16bpp and others.
S3 side:
Temporary changes to match the release (due to tomorrow) of 86box. Said changes are about the horizontal display of the tvp3026-based S3 chips.
IBM/ATI 8514-based:
Temporarily commented out the hblank side of it due to htotal bugs.
TVP3026 side:
When the upper clock selection bits are 0 and when extended VGA modes are set, double the hdisp.
* Fixes cursor disappearing completely in Matrox cards in some cases.
* Allows emulated video adapters allowing negative Y values for hardware cursor to render those properly
1. Second attempt to fix the banking in the Cirrus (sigh, why doesn't banking get nulled automatically...)
2. Introduce a new timer to the 8514/A side so it won't slow the VGA clock down it was shared before.
* Fix duplicated logic in vid_svga.c
* Voodoo 3/Banshee emulation now has blanking extensions applied
* S3 ViRGE and Matrox video cards as well
* Tseng ET4000-series cards as well
* Fix off-by-one error in vid_cl54xx.c
Trident cards are yet to be investigated. XGA and 8514/A are yet to be made blanking extensions compliant. Mach64, Paradise/WDC and OAK OTI cards remain as-is for now.
1. Made the 4 color mode (67h) work properly now, including its 4 schemes on all ATI cards that support said mode.
2. Shadow set now has a true purpose for 8514/A compatibility on ATI Mach8/32.
3. Non-ATI 8514/A used to not work before because of the dev->local variable was not being set to 0 in the ibm8514_init() function, now it's fixed.
1. Reverted the packed chain4 and fb_only sides to 1 when extended mode is set, but with the call to svga_recalctimings removed from port 0x3df due to mode issues, this should fix all the MGA mode issues I know.
2. Cleaned up the rendering order in svga_recalctimings, especially 4bpp and 8bpp.
1. Update svga->fast to account for packed chain mode toggles, fixes issues on Descent II for DOS using the Cirrus cards.
2. Re-organized ATI Mach8/32 LFB access as well as 8514/A/ATI mode toggles, should end the video mode issues once and for all.
3. Fixed a small but major pattern issue with IBM OS/2 1.30.1's XGA driver (not .2, which is fine as is).
1. Made the 8514/A mode switch to VGA and viceversa (including ATI mode) actually usable and eliminating the last bugs related to them. Fixes 8514/A mode in OS/2 1.x/2.x (both IBM and Microsoft).
2. More sanity checks to the 8514/A and XGA pointers. Should fix emulator crashes on hard resets.
the XGA memory test takes account of Win3.x' XGA memory test again without conflicting XGAKIT's test, fixes DOS-based boxes using Win3.x XGA drivers in 386 mode.
ATI Mach64 is temporarily unthreaded because of blitter desyncing.
ATI Mach32 now returns to ATI mode from IBM mode and vice versa more correctly.
Make the IBM 8514/A compatible poll not run if a 3D add-on card (Voodoo1/2) takes precedence (seen on a Mach32 PCI and Voodoo2 3D combo).
Finally ended the mess ups of the TGUI9440/96x0 pitch, it actually was the CRTC offset reg (SVGA CRTC 0x13) that defined it with some shifting based on the BPP.
1. Cirrus Logic GD54xx, Paradise/WD VGA now reset the interlace once a text mode is issued if not done automatically.
2. Paradise/WD's 15/16bpp modes using the 800x600 resolution now have the correct ma_latch, should fix most operating systems drivers using this combo.
3. More fixes (hopefully) to the accelerated pitch and rowoffset of the Trident TGUI cards (9440AGi and 96x0XGi), should fix issues with delayed displays mode changes under various operating systems (e.g.: Win3.1x).
4. Preliminary implementation of the Area Fill command of XGA, which is issued while using various painting and/or calc utilities on Win3.1x (IBM XGA updated drivers, e.g.: 2.12).
5. Preliminary (and incomplete) 4bpp XGA mode.
6. The XGA memory test for the 0xa5 using writes (used by various operating systems) no longer conflicts with DOS' XGAKIT's memory detection.
7. Small ROP fixes to both XGA and 8514/A.
8. Re-organized the mapping of the Mach32 chipset, especially when to enable the ATI mode or switching back to IBM mode, should fix LFB conflicts with various operating systems.
9. According to The OS/2 Museum, the Adaptec AHA-154xB series of SCSI cards fail the ASPI4DOS.SYS 3.36 signature check, so now make the changes accordingly.
10. Remove useless and crashy bios-less option of the Trantor T128.
11. The Image Manager 1024 card can also be used on a XT (although only if it has a V20/V30).
12. Re-organized the IBM PS/2 model 60 initialization as well as its right POS machine ID (though an update to sc.exe is still required for the POST memory amount to work normally).
* separate (ibm8514|xga)_enabled into (ibm8514|xga)_standalone_enabled
and (ibm8514|xga)_active, the former being enabled only for standalone
8514/A or XGA cards, the latter for all 8514/A and XGA-capable cards
and not saved into the config file;
* remove (ibm8514|xga)_has_vga and replace all uses of it with
(ibm8514|xga)_standalone_enabled;
* Qt UI: the checkboxes for standalone 8514/A and XGA are now correctly
grayed out if an (S)VGA card with 8514/A or XGA capability is selected,
including cases when the card is an internal/onboard one; said cards are
now no longer appear as SVGA multi-monitor compatible.
1. Hopefully fixed the passthrough stuff for good and fixed typo's in the IBM 8514/A poll function about the cursor.
2. Eliminated the ibm8514_on global variable in favor of a struct variable to be consistent with XGA.
1. The passthrough from VGA to 8514/A and/or 8514/A to VGA no longer relies on hackish places where to switch from/to, instead, relying on port 0x3c3 of VGA doing so (though the Mach8/32 still needs some places where to manually switch from/to, mainly the MCA one when configuring the EEPROM).
2. Implemented the MCA behalf of the Mach32 and its corresponding reset function.
3. Properly implemented (more or less) true color, including 24-bit BGR rendering
4. Other fixes such as color patterns and mono patterns being more correct than before in various operating systems and in 24-bit true color.
5. Implemented the onboard Mach32 video of the IBM PS/ValuePoint P60 machine.
6. Made the onboard internal video detect when it's 8514/A compatible or not (CGA/EGA/MDA/VGA/etc.). If the former is selected, then the video monitor flag is used instead (for QT).
7. The TGUI9400 and 9440, if on VLB, now detect the right amount of memory if on 2MB.
8. Initial implementation of the ATI 68875 ramdac used by the Mach32 and made the ATI 68860 8514/A aware when selected with the Mach32AX PCI.
9. Separated the 8514/A ramdac ports from the VGA ramdac ports, allowing seamless transition from/to 8514/A/VGA.
10. Fixed a hdisp problem in the ET4000/W32 cards, where it was doubling the horizontal display in 15bpp+ graphics mode.
11. Removed the 0x3da/0x3ba port hack that was on the Mach8/32 code, relying on the (S)VGA core instead.
12. Reworked and simplified the TGUI9440 pitch register based on logging due to no documentation at all.
