1a5b4671e8 XGA/SVGA mode changes of the day (July 22nd, 2025) 
1. If the VGA mapping is for a 0xA0000 map for a length of 0x10000, then disable XGA mode (this is independent of the XGA extended mode aperture mode 1 which is XGA's own 0xA0000 mapping).
2. Remove text mode ctrl-alt-del hack.
3. Fixed cursor x coordinate in the Trio32 using 15bpp/16bpp modes.

6c933dd157 Voodoo: Implement missing AGP CMDFIFO features 
Note that the reproduction cases for command 6 currently appear to be a result of CMDFIFO corruption instead of actual usage.

9aad8dbf9c Add basic support for the Quantum3D Raven. 
AGP was worked on but found to be unstable (freezing on the first frame whenever entering Direct3D fullscreen), so it was removed.

8e9a2e0b79 Apply blanking extensions to more SVGA cards. 
* 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.

c30d5d90b7 PCI and IRQ rework, pci.c rewritten from ground up, fixes numerous issues such as the bridge being added when the number of normal PCI devices equals the number of normal PCI slots, Windows 95 PCI operation on Intel 430NX, sharing of PCI IRQ's with non-PCI level-triggered devices, having both configuration mechanisms operating at the same time (ALi M1435), etc., and makes the code much more readable. 2023-08-07 03:04:52 +02:00
