8e3b09f323 Various 486 improvements 
- Added SL-Enhanced versions of Intel 486 CPUs and Enhanced AMD Am486DX2/DX4 CPUs
- Cleaned up the 486 CPU types and updated intel_4x0.c to reflect this
- Fixed some incorrect EDX reset and CPUID values
- Blacklisted non-SMM capable 486 CPUs on the Soyo 4SA2 motherboard
- Merged the non-OverDrive and OverDrive Intel DX4s because of further research confirming them to be functionally identical
- Removed SMM support on early 486 CPUs

1d4988221f Fixed SYSENTER, SYSEXIT, SYSCALL, and SYSRET; 
SYSCALL and SYSRET are now perfectly in line with AMD's specification;

0faf6692c9 WARNING: CONFIGS MIGHT PARTIALLY BREAK WHERE DEVICE NAMES HAVE CHANGED. 
Changes to device_t struct to accomodate the upcoming PCI IRQ arbitration rewrite;
Added device.c/h API to obtain name from the device_t struct;
Significant changes to win/win_settings.c to clean up the code a bit and fix bugs;
Ported all the CPU and AudioPCI commits from PCem;
Added an API call to allow ACPI soft power off to gracefully stop the emulator;
Removed the Siemens PCD-2L from the Dev branch because it now works;
Removed the Socket 5 HP Vectra from the Dev branch because it now works;
Fixed the Compaq Presario and the Micronics Spitfire;
Give the IBM PC330 its own list of 486 CPU so it can have DX2's with CPUID 0x470;
SMM fixes;
Rewrote the SYSENTER, SYSEXIT, SYSCALL, and SYSRET instructions;
Changed IDE reset period to match the specification, fixes #929;
The keyboard input and output ports are now forced in front of the queue when read, fixes a number of bugs, including the AMI Apollo hanging on soft reset;
Added the Intel AN430TX but Dev branched because it does not work;
The network code no longer drops packets if the emulated network card has failed to receive them (eg. when the buffer is full);
Changes to PCI card adding and renamed some PCI slot types, also added proper AGP bridge slot types;
USB UHCI emulation is no longer a stub (still doesn't fully work, but at least Windows XP chk with Debug no longer ASSERT's on it);
Fixed NVR on the the SMC FDC37C932QF and APM variants;
A number of fixes to Intel 4x0 chipsets, including fixing every register of the 440LX and 440EX;
Some ACPI changes.

795a6017d2 PIC rewrite, proper SMRAM API, complete SiS 471 rewrite and addition of 40x, 460, and 461, changes to mem.c/h, disabled Voodoo memory dumping on exit, bumped SDL Hardware scale quality to 2, bumped IDE/ATAPI drives to ATA-6, finally bumped emulator version to 3.0, redid the bus type ID's to allow for planned ATAPI hard disks, made SST flash set its high mappings to the correct address if the CPU is 16-bit, and added the SiS 401 AMI 486 Clone, AOpen Vi15G, and the Soyo 4SA2 (486 with SiS 496/497 that can boot from CD-ROM), assorted 286+ protected mode fixes (for slightly more accuracy), and fixes to 808x emulation (MS Word 1.0 and 1.10 for DOS now work correctly from floppy). 2020-10-14 23:15:01 +02:00

a862bda04c Rewrote the recompiler interrupt checking in assembly (and removed it for the new dynamic compiler because the requires uops are not present), brings performance back up, and also did a number of CPU-related clean-ups (mostly removal of dead variables and associated code). 2020-07-13 19:46:19 +02:00
