8fca57aa79 Universalize the keyboard and mouse latches again, fixes #3280. 2023-05-01 01:35:16 +02:00
OBattler
78a897f07a Some minor fixes, the PS/2 mouse command F0h (set remote mode) is now implemented, the PS/2 mouse command F3h (set sample rate) now actually changes the host mouse polling rate, and the Intel SIO IB and ZB now forcibly initialize a keyboard and mouse IRQ latch if the board has a PS/2 keyboard controller, to simulate the presence of a latch external to the chip. 2023-04-26 01:42:23 +02:00

df24b4be0f Reverted the previous approach and switched to the new, non-hacky approach of getting rid of the accelerator and instead handling enter full screen the same way exit full screen is handled. 2023-04-13 22:47:42 +02:00

b753c675fb Fixed the PS/2 keyboard and mouse latch initialization - now the mouse latch actually works, fixes mouse in AMI WinBios Setup and 8603 errors on MCA IBM PS/2's. 2023-04-12 20:23:31 +02:00

ef17003f1b Fixed the "minor bug fix" in the AT / PS/2 keyboard controller, reworked PS/2 keyboard controller IRQ latches, and correctly disabled memory top remaps if there's more than (16 MB - remap size) RAM (fixes segmentation faults on some machines with 16+ MB of RAM). 2023-04-11 23:21:52 +02:00

289962319f Rewritten the PS/2 poll (without the password security state, that is yet to be done) and enabled the PS/2 KBC IRQ latch on all PCI machines as well (it is present at the very least on Intel SIO and PIIX), fixes Windows for Workgroups 3.11 input, and reduced mouse polling to 255 Hz (the maximums supported by PS/2 mice). 2023-04-08 00:40:57 +02:00

c06e9b35f2 Fix PIC level-triggered interrupts on IRQ's 0 to 7 (spotted by TC1995). 2023-01-26 22:29:51 +01:00

27ebb27db7 Makefile.mingw corrections and made the code pass much stricter checks (now mandated by Makefile.mignw) to ensure GCC 14 readiness. 2022-11-17 22:44:06 +01:00

80095e7a30 Two PIC fixes (implementation of freeze between the two INTA pulses for PC/XT, and find_best_interrupt() treating ISR'd cascaded slave IRQ's the same way as other IRQ's), and removed the incorrect IRQ latch reading. 2021-04-01 05:44:26 +02:00

bf4b5b781f Implemented PIC IRQ latch and delay (per the datasheet), IBM PCjr now works without a workaround delay in cpu/808x.c which was therefore removed; also redid memory and I/O accesses in cpu/808x.c to fix word writes on 8086. 2020-11-17 00:25:28 +01:00

cfb559de13 Made the 808x interrupts delay again, fixes PCjr (TODO: Find why exactly that's needed because it sounds like a hack to me); 
Fixed compiling of the PIC code with logs enabled;
A number of bugfixes in cpu/x86seg.c, fixes OS/2 1.0.

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

ec74ffb6a5 Old recompiler improvements: limited in-block IRQ checking to floppy IRQ's only, rewrote the GPF handlers in ASM, and changed the recompiled INC and DEC instructions to actually use INC and DEC on host. Also removed the keyboard_at.c timer hack. 2020-07-15 05:03:19 +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

275dd5a2f7 ACPI, SMM, and PIIX fixes, fixes quite a few boards, also fixed the Via Apollo series northbridge ID's, some CPU instructions on both 808x and 286+, and added SMM to 486's (Intel and AMD), WinChip and WinChip 2, and VIA Cyrix III, also removed the TC430HX and the Toshiba machine from the Dev branch. 2020-04-16 21:56:19 +02:00

a505894a10 Move all include files to src/include 
- 86Box's own headers go to /86box
- munt's public interface goes to /mt32emu
- all slirp headers go to /slirp (might want to consider using only its public inteface)
- single file headers from other projects go in include root
