1. The Debian issue mystery lies around chain2_read/write being required when the LFB mapping is enabled too when MGA modes are set without blitting, however, when it is blitting, immediately tell chain2 to not interfere with the mapping. Fixes Debian once and for all as well as VRAM detection correctly while keeping existing compatibility fine.
2. Undev branch the G100 per above. (Revert if more bugs are revealed).
3. An AND with 0 is not tolerable as it nulls the LFB, fixes hang ups with Win2000 using the Millennium II and possibly the G100.
4. the Extended CRTCs now have a call for timing recalculation, fixes mode changes when blitting is going on.
1. When the 128K banking is activated, use a mask of 0xffff instead of 0x1ffff.
2. Debian uses standard VGA mapping when in chain4 mode and its lfb is adapted accordingly.
3. Fixed the decode VRAM mask on the Millennium II so that the vram is detected correctly and no more glitches.
4. Undev the Millennium II as well.
1. Cleanups and moving the mach8/32 struct to a dedicated header so that would allow for future 8514/A add-on clones (in paper).
2. Mach8/32's port 0x4ae8/9 and shadow set ports (0x5aee and 0x46ee) now account to the mode changes seriously, should fix most of the horizontal/vertical coordinates while entering GUI modes of various stuff.
3. Horizontal/Vertical window coordinates can only be modified if the display enable bit of port 0x22e8 is set as well as bit 0 of port 0x4aee, fixes most problems noted above.
4. Implemented horizontal blanking stuff a la VGA but actually for 8514/A and clones (like ATI).
5. Added some comments regarding the current situation.
6. The Mach8 was actually a 8514/A clone co-processor, not a single solution card of its own. The ATI Graphics Ultra was a single solution card that is actually a Mach8 + ATI 28800-6 in one, so renaming it accordingly.
7. Fixed garbled/distorted acceleration when device bitmap acceleration is enabled in the ATI Mach8 3.0 Win3.1 drivers.
1. Proper cleanup of the code.
2. Migrate the card in question to the VGA class list as it's actually a rebadged VGA Edge (thus 18800).
3. Some VGA only features are not supported on this card and are documented in the recalctimings.
* 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. 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.
Added the Mach8 and Mach32 ISA/VLB/PCI cards (initial implementation and MCA coming soon for the Mach32) and their corresponding EEPROM's.
Added INMOS XGA ISA card and updated the SVGA core to reflect its mapping as well as the Mach8/32 mapping when in 8514 monitor mode.
Mark the XGA button as already checked and locked when a standalone XGA BIOS card is present like the INMOS one. (QT only)
Same concept as above, but applies to the Mach8 and 32 for the 8514 option as well. (QT only)
