12d5d6c260 Matrox Mystique: Bus-mastering fixes 
* Make all bus-mastering-related variables atomic
* Do not, under any circumstances, attempt to read beyond PRIMEND and SECEND

This allows NT 4.0's Mystique drivers to work with busmastering enabled.

f5642ab1c3 MGA fixes 2: 
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.

c1ba150e3c Oops, they actually can mix together, but not with plain (non-packed) chain4 stuff enabled, should fix more mode issues in the MGA Millennium card. 2023-12-18 00:40:31 +01:00

c62182cd2e MGA Fixes: 
1. LFB access is now done properly through the right svga_read/write linear calls.
2. Lowres 8bpp mode and Packed/Extended 8bpp+ mode don't mix together, fixes Debian Woody matroxfb module when testing the modes while keeping other compatibility intact (basically enable packed stuff only when gdcreg5 bits 5-6 are 0 when extended mode is set).
3. Small cleanup in the line accel stuff.

0848f4a38e Disable blink in 8bpp modes on MGA; Re-instate main 8bpp hires renderer 
I don't actually know if 8bpp blink is a thing on a Matrox Millennium, but the video BIOS seems to act like it's not.

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
