216124c6c3 Send #MF exception for MMX instructions if there is a pending FPU exception 2003-04-05 12:49:14 +00:00
Stanislav Shwartsman
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.

Peter Tattam
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.

7cdea60d53 - key event handling of the win32 gui fixed. Now the function

  are now converted to bx_key values.

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);

f25a3df39b - added minimal USB support (patch from Ben Lunt <fys@cybertrails.com>, updated 
and improved by Christophe Bothamy and Volker Ruppert)

Comment from the author:

Attached is a "patch" file detailing what you need to do
to add USB support (UHCI only for now) to your existing
Bochs (2.0.xx) source code.

I use Win32 and VC++ but the source and modifications
should be platform and compiler independant.

Please let me know if this patch some how breaks the
build process of your compilation (Bochs 2.0.0 or above
only).

I would also like any feedback on how this code works
(or doesn't work) on your platform and within your
images. If you explain in as much detail as you can on
how it did or did not work, I will try to add to the source
to help it work on all platforms and images.

  stosd, lodsd and scasd.

Peter Tattam
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.

Kevin Lawton
87d648682e Code cleanup. Moved the interrupt redirection instrumentation 
into the host-specific files and wrapped access to them
  with atomic operations since that's a structure global to
  all the VMs.  I think all the other globals are SMP clean
  since they are only written once during module init time,
  and read thereafter my all VMs.
Renamed all host OS specific functions to hostOS*().  All host
  independent functions to host*().
I'd like to rename all monitor space functions to mon*() next.

387dcf520f Modified to comply with new way of mapping user space pages 
into the plex86 kernel module and VM.  mmap() is not used
  any more.
 2003-01-09 04:03:36 +00:00
Kevin Lawton
f45a747e59 Got rid of use of mmap() altogether. User space (bochs) allocates 
all the memory it needs, and the plex86 kernel module uses
  get_user_pages() from the Linux kernel to get at them and
  pin the few that are needed statically (and later up to
  a watermark of pages that are needed dynamically).
Guest physical memory pages are now dynamically pinned/unpinned.
  For now, I use a hard limit of 4Megs of pinned pages and
  a really primitive algorithm to decide which one to unpin
  when the limit is reached and one needs to be bumped.  Seems
  to work.  Though I haven't run into the limit yet since I'm using
  just a small test program.

and pinning user pages from the plex86 kernel module.  The
  guest physical memory array is no longer mmap()'d from kernel
  space where it used to be allocated.
 2003-01-08 17:22:07 +00:00
Kevin Lawton
6b2c7ef341 Changed over from allocating the the guest physical memory area 
in the plex86 module and mmap()'ing it into user space (bochs),
  to letting bochs malloc() it normally and using the
  Linux kernel facility get_user_pages() to get the associated
  physical pages and pin them in memory.  I only have code for
  Linux kernel 2.4.20 and up, as that's the first version to
  export the get_user_pages() symbol so modules can use it.
