8850cbf768 - removed BX_CPP_AttrRegparmN() from the i/o read handler. The read access 
failed with this optimization. I guess the reason for the failure is the
  void* argument.

5c38c04fb4 - fixed possible segmentation fault in parse_line_formatted(): cause a PARSE_ERR 
if a bochsrc option comes without a parameter.
- comment handling in parse_line_formatted() no longer needed

3411535a8b - 'split screen' feature for standard VGA 16-color modes implemented 
* new variables 'line_compare' and 'vertical_display_end' depend on CRT
    register values
  * implemented 'split screen' in functions update() and mem_write()
- mem_write(): CGA section: unnecessary variable 'isEven' removed

8b22768895 - applied some speed optimizations in mem_write() from patch.vga-mode2-speed-dohzono 2003-05-01 12:07:27 +00:00
Volker Ruppert
d02c729791 - removed variable 'scan_bits' and added new variable 'line_offset'. It specifies 
the address offset between two lines on the screen in all VGA modes.
  It depends on the CRTC offset register value and the address mode (byte, word,
  dword)
- moved screen update code to the end of the write handler. If a register change
  should force a redraw of the screen, the variable 'needs_update' must be set
  to 1.
- changes to the attribute controller palette index register now force a redraw
  of the screen
- modeX: calculation of the tile numbers fixed

b1324da2e1 - function mem_read() rewritten 
* check memory mapping before everything else
  * read mode 1 optimized using a part of patch.vga-mode2-speed-dohzono
- function mem_write(): check memory mapping before everything else
- writes to the CRT registers are handled only if the new value differs
- a CRT start address change forces a redraw of the screen

a6dd6deaf5 - apply patch from James E. Flemer: 
I've got a game that uses OPL2 functions.  It's still not
working yet, but this patch brings it closer.  Using Jeffrey S.
Lee's "Programming the AdLib/Sound Blaster FM Music Chips (Ver
2.0)"[1] as a reference, I found an inversion of the OPL timer
masks in the sb16 code.  Without this patch, the emulator uses
the wrong bits for masking, and completely botches the flags
register (note the bitwise AND vs OR).

1e71c9e56e Merged patch-unallowed-lock-cases patch. 
According to the Intel manuals:

  The  LOCK  prefix  can be prepended only to the following instructions
  and  only  to  those  forms  of the instructions where the destination
  operand  is  a  memory operand: ADD, ADC, AND, BTC, BTR, BTS, CMPXCHG,
  CMPXCH8B,  DEC,  INC,  NEG, NOT, OR, SBB, SUB, XOR, XADD, and XCHG. If
  the  LOCK prefix is used with one of these instructions and the source
  operand  is a memory operand, an undefined opcode exception (#UD) will
  be  generated. An undefined opcode exception will also be generated if
  the  LOCK  prefix  is used with any instruction not in the above list.

 Checking of the LOCK prefix done in fetchDecode state and not overloads
 Bochs's execution.

0f94706c80 minor tweak to 64 bit stack push to ignore segmentation checks. Not required in 64 bit mode so is

de1b90d978 pit_wrap.cc never uses the realtime stuff anymore. 2003-02-18 16:57:44 +00:00
Gregory Alexander
b77b477bfa The PIT is going to start using virtual timers instead 
of having its own realtime mechanism.  The old PIT
realtime mechanism will be removed next.

4ea5f058f5 This is a hideously ugly hack that removes some of the 
speed throddling.  However, it keep up with real time now.

f844486d08 Fixed some basic runtime problems. 
Stuff runs now, but I'm working on getting it to behave properly.

7cdea60d53 - key event handling of the win32 gui fixed. Now the function 
DEV_kbd_gen_scancode() is called instead of DEV_kbd_put_scancode(). This
  change enables the support for different scancode sets. The win32 scancodes
  are now converted to bx_key values.

c0d7138924 Working on a general-purpose virtual timer interface. This should allow 
more consistent time interfaces once it's finished.
 2003-02-14 21:05:36 +00:00
Gregory Alexander
f12a510b8b Added a strictly increasing timer. 
This is only somewhat useful here, but will be more
useful when the general timer interface is available.

7fa75388a1 Added bx_cpuid value to the BX_CPU class to avoid any problems with BX_CPU_ID implementation 2003-02-13 15:51:22 +00:00
Stanislav Shwartsman
cdfc3cbce4 instrumentation enchancements: 
* renamed CPU_ID to BX_CPU_ID.
  with this new name there is no possibility for name contentions and BX_CPU_ID
  definition could be moved out to NEED_CPU_REG_SHORTCUTS block

* returned back `unsigned BX_CPU::which_cpu(void)` function

* added BX_CPU_ID parameter for
	BX_INSTR_PHY_READ(a20addr, len);
	BX_INSTR_PHY_WRITE(a20addr, len);
    now it will be
	BX_INSTR_PHY_READ(cpu_id, a20addr, len);
	BX_INSTR_PHY_WRITE(cpu_id, a20addr, len);

d4575083a7 - add performance patch contributed by Conn Clark. 
It uses special gcc attribute regparm, available on gcc3.2 on x86.
  I get about 7% increase when booting windows 95.
  The patch still need some integration work before being included
  in the main code.

b716dafbcc - user_shortcut feature: new key name "bksp" (backspace) added 
- function userbutton_handler(): stop parsing the shortcut string if the
  key name is invalid
- function userbutton_handler(): incrementing variable 'len' simplified
- function snapshot_checker(): fixed a warning

7336c891ee - CPU_ID fix from Shai Fultheim, who writes: 
> CPU_ID is defined as
  > #define CPU_ID (BX_CPU_THIS_PTR local_apic.get_id())
  > This is not true when the APIC name is changed (true in Linux). Please
  > change this to:
  > #define CPU_ID (BX_CPU_THIS - BX_CPU(0))

e492acd792 - VBE 4 bpp modes are using the default vga read/write/update code (for VESA 
mode 0x102 = SVGA mode 0x6a)
- function redraw_area() now uses the old screen dimensions for redrawing
