a07ffdecab Restore the debug register operation on 486+ 
But put it behind a compile-time option due to performance hits
Also add the DE flag to CPUID on supported CPUs

c695cb8ded Completely reworked mouse handling - should now be smoother due to there no longer being a multi-layered game of telephone going on with all the various interim coordinate counters, also rewritten the serial mouse emulation ground ground up. 2023-08-07 18:49:58 +02:00

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

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

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

72c1c36ec6 OPTi 5x7 no longer does excess logging, running of timers on the recompiler is now done on every fourth AT KBC port 61h read instead of every 3F4h read, added some safety precautions to io.c to handle the cases where a handler removes itself, implmented the STPC ELCR and refresh control, and fixed the messed up register reading in the PC87307 and PC87309 implementations. 2020-07-10 02:05:49 +02:00

96228bc41d Overhauled the SiS 496/497 chipset emulation (and added the DRB locking to it) (later Zida Tomato 4DPS BIOS'es now work, and we now use the actual 1.72), fixed the W83787F and FDC37C932FR Super I/O chips, removed the no longer needed Acer M3A registers (that's now correctly handled as FDC37C932FR GPIO), and a number of bugfixes here and there. 2020-06-29 01:10:20 +02:00

3a401af84e Changes to update_tsc() - no longer requires a parameter and advances by all the currently accumulated cycles. Also changed TSC-related delta's to be correctly uint64_t. 2020-05-14 01:36:52 +02:00

f46181db78 Several fixes - the MR BIOS'es now work on the recompiler (thank you, port EBh!), so they have been moved out of the Dev branch. 2020-05-13 03:43:02 +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
