94880d1412 Fix guest2host and related optimizations to work on 64 bit host.
1) fixed the type of "hostPageAddr" and associated typecasts.
2) fixed the type of "pages" and associated typecasts (overloaded variable)
3) patch to cpu.cc to calculate "eipPageBias" correctly in 64 bit mode

11a12142bc x64-64 emulation updates.
1) fixed some errors running 32 bit compat mode.  IMPORTANT FIX.
2) added IST processing (uses IST1-IST7 in 64 bit TSS)
3) cosmetic - debugging stuff to console.

0f94706c80 minor tweak to 64 bit stack push to ignore segmentation checks. Not required in 64 bit mode so is
a minor optimization.  Also in transition from compat mode to 64 bit mode (e.g. interrupt to inner
privelege with mode change), SS may not be properly defined - this avoids other messiness.

131bbb54c5 When external debugger enabled, change INT1 to be
transparent (i.e. not call the guest int1 ISR)

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

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);

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))

24d4a5003c patches to CPUID required to get latest x86-64 linux kernel (2.4.20) to run.
I believe this patch is ok, however it should be regression tested to make sure
nothing is broken.

b2622c5d04 Temporary tweak to reinstate a change that disappeared when sse2.cc was removed.
The 64 bit variant of MOVNTI was not decoded.  The proper fix for this is to work on
fetchdecode64.cc to call a 64 bit variant of SSE instructions or fail it with a
invalid op.  A careful check needs to be done with the AMD manuals to determine if
there are any other SSE instructions that have a special 64 bit decoding.

7e41d08620 Fixed problem with shift imm instructions 2002-12-30 08:03:34 +00:00
Stanislav Shwartsman
e1d5cddc6d Fixed a problem with zero-count shift in following instructions:
PSRAW_PqQq    (MMX)
PSRAD_PqQq    (MMX)
PSRAW_PqIb    (MMX)
PSRAD_PqIb    (MMX)

PSRAW_VdqWdq  (SSE)
PSRAD_VdqWdq  (SSE)
PSRAW_PdqIb   (SSE)
PSRAD_PdqIb   (SSE)

When register was shifted by 0 bits the result produced was incorrect.

Now Bochs fully passes MMX test provided by

c173034663 Patches to round off the x86-64 emulation to get the Linux x86-64 kernel and
sash to run.

1) fixed fetchdecode64.cc to fix the operand size at 64 bits in long mode for moves
   to/from CRx

2) minor patches to sse2.cc to fix unimplemented and 64 bit variants of sse2
instructions.

9b2914fd1d - Temporarily revert Stanislav's changes between 2002-12-18 and 2002-12-19.
Because source files were added/removed it would require an update
  of the windows and macos project files, so I want to wait until after 2.0.
    M Makefile.in         1.51 back to 1.50
    M cpu.h               1.121 back to 1.120
    M fetchdecode.cc      1.37 back to 1.36
    M fetchdecode64.cc    1.33 back to 1.32
    M sse.cc              1.17 back to 1.16
    A sse2.cc             1.27 back to 1.26  (added back)
    R sse_move.cc         removed
    R sse_pfp.cc          removed
- to bring these changes back again, all we have to do is
  "cvs update -j tmp-before1 -j tmp-after1"
