Shwartsman e4deec2aca cleanups and code updates before thinking of INIT redirection implementation for AMD SVM 2024-01-14 12:55:43 +02:00
Shwartsman 61a35063c5 remove all ifdefs from features.h 
I'd like features bitmasks to be independent on Bochs compilation flags
so let all flags to be 'exists' even if corresponding feature is not compiled in.

Volker Ruppert 04ed1e8fd2 Some more VGA timing handling chages. 
- Changing status of 'update_mode_vsync' is no longer supported at runtime.
  If disabled, changing the value is only valid between 1 and 75.
- Modify vtotal_usec if frequency to high before activating vsync_timer.

Stanislav Shwartsman 540c7bbf64 update and cleanup CHANGES 2024-01-13 20:53:54 +02:00
Volker Ruppert 1ebe15e3fc Rewrite of the VGA timing code. 
- Added VSYNC timer handler using vertical total usec. The calling time is defined
  as vertical retrace end and it updates the CRTC start address like real VGA does.
  It also calculates the display start time used when reading the input status register.
  The VSYNC timer is disabled in Voodoo / Banshee modes.
- Improved VGA timing calculation (e.g. vertical blanking and retrace start).

Stanislav Shwartsman 6977fc05d9 VMX: adjust RFLAGS saved into guest state on VMEXIT according to VMX documentation: 
For APIC-access VM exits and for VM exits caused by:
- EPT violations
- EPT misconfigurations
- page-modification log-full events or
- SPP-related events
the value saved depends on whether the VM exit occurred during delivery of an event through the IDT ...

also handle RFlags saved if VMEXIT was caused directly by an event that would normally be delivered through the IDT

should fix #215

Volker Ruppert 5b6872168a Banshee: Attempt to implement 8 and 16 byte writes to CMDFIFO. 
- The mem_write_handler() splits 16 bytes writes in two 8 bytes writes.
- In mem_write() the 8 byte writes to CMDFIFO are split in two 32-bit writes.

Shwartsman 89d992b5b8 fixed (#214) wrong MSR name typo in MSR error message

AMX support (#212) 2024-01-10 20:13:25 +02:00
Volker Ruppert cfa7276cb9 Added support for driving the VGA display update timer with VSYNC. 
- Using the special value of 0 enables this feature. In that case the vertical
  frequency is used for the display updates. The update() method is called at
  the "vertical retrace end" time and sets the time of the display start. This
  value is used to set the vertical retrace indicator in VGA register 0x03da.
- This feature is not yet enabled if Voodoo support is present. The Voodoo device
  has it's own vertical timer and needs some more testing and possibly some changes.
