1755589376 Separate pageWriteStamp from ICACHE. The pageWriteStamp has totally independant structure and could be used in future with icache structure. Also it could be significantly speeded up using BX_SMF analog constructions. 2005-04-10 19:42:48 +00:00

f9bd2b74be 1. Fixed bug in FSUB instruction
2. Fixed bug

[ 989478 ] I-Cache and undefined Instruktions

The L4 microkernel uses an undefined instruction to
trap for a special requests into the kernel (LOCK NOP).
The handler fixes this up and gives the user a special
code page with syscall stubs. If you're not using the
I-Cache optimization everthing works find on bochs. But
if you enable the I-Cache (--enable-icache), then the
undefined opcode exception is thrown only once for ever
virtual address it occurs. See the demodisk of the
L4KA::pistachio
(http://www.l4ka.org/projects/pistachio/download.php).
In this case the pingpong benchmark of this demo is of
interest. Everything runs fine until the program tries
to spawn a new task for its measurements. This new task
shares the code of the creating program. But the new
task stops executing at the undefined instruction
explained above and no exception is thrown.

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);

cec9135e9f - Apply patch.replace-Boolean rev 1.3. Every "Boolean" is now changed to a
"bx_bool" which is always defined as Bit32u on all platforms.  In Carbon
  specific code, Boolean is still used because the Carbon header files
  define it to unsigned char.
- this fixes bug [ 623152 ] MacOSX: Triple Exception Booting win95.
  The bug was that some code in Bochs depends on Boolean to be a
  32 bit value.  (This should be fixed, but I don't know all the places
  where it needs to be fixed yet.)  Because Carbon defined Boolean as
  an unsigned char, Bochs just followed along and used the unsigned char
  definition to avoid compile problems.  This exposed the dependency
  on 32 bit Boolean on MacOS X only and led to major simulation problems,
  that could only be reproduced and debugged on that platform.
- On the mailing list we debated whether to make all Booleans into "bool" or
  our own type.  I chose bx_bool for several reasons.
  1. Unlike C++'s bool, we can guarantee that bx_bool is the same size on all
     platforms, which makes it much less likely to have more platform-specific
     simulation differences in the future.  (I spent hours on a borrowed
     MacOSX machine chasing bug 618388 before discovering that different sized
     Booleans were the problem, and I don't want to repeat that.)
  2. We still have at least one dependency on 32 bit Booleans which must be
     fixed some time, but I don't want to risk introducing new bugs into the
     simulation just before the 2.0 release.

3fe65ab230 - enable dbg_fetch_mem and dbg_set_mem when compiling for GDB stub 2002-10-03 05:15:28 +00:00
Bryce Denney
4c9776fb96 - add -lwinmm to the link lines anytime you use --enable-sb16=win. Now
instead of winmm being a part of GUI_LINK_OPTS_WIN32 only, it is
  placed in @DEVICE_LINE_OPTS@ so that it will be used for sdl, rfb, wx,
  etc.
- solve compile problems when building bximage, niclist, and any other
  console based program.  The compile flags returned by wx-config and
  sdl-config did strange things to these console programs, for example
  redefining main to SDL_main.  Because I wanted to use the
  configure-generated CFLAGS to compile the programs, but I wanted to
  avoid including GUI specific compile options, I split up the configure's
  @CFLAGS@ variable into @CFLAGS@ and @GUI_CFLAGS@, and split
  @CXXFLAGS@ into @CXXFLAGS@ and @GUI_CXXFLAGS@.  All programs in the
  Bochs binary will use both, but the console programs will just use
  @CFLAGS@ or @CXXFLAGS@.
- gui/Makefile.in, I no longer use the gui specific CFLAGS variables,
  SDL_CFLAGS and WX_CXXFLAGS.  These values are included in CFLAGS and
  CXXFLAGS now.
- modified: configure.in, configure, all Makefile.in's

b742ccec7e Changed eflags accessors for get_?F() to use (val32 & (1<<N)) instead
of (1 & (val32>>N)), and added a getB_?F() accessor for special
  cases which need a strict binary value (exactly 0 or 1).  Most
  code only needed a value for logical comparison.  I modified the
  special cases which do need a binary number for shifting and
  comparison between flags, to use the special getB_?F() accessor.

Cleaned up memory.cc functions a little, now that all accesses
  are within a single page.

Fixed a (not very likely encountered) bug in fetchdecode.cc (and
  fetchdecode64.cc) where a 2-byte opcode starting with a prefix
  starts at the last offset on a page.  There were no checks
  on the segment overrides for a boundary condition.  I added them.

The eflags enhancements added just a tiny bit of performance.

Kevin Lawton
0cd7346b9c - Added an instruction cache. Size is fixed for the moment,
but if you hand edit cpu/cpu.h, and change BxICacheEntries,
  you can try different sizes.  I'll make this more flexible
  with configure.  For now, use "--enable-icache" with no parameters.

- Modified fetchdecode.cc/fetchdecode64.cc just enough so that
  instructions which encode a direct address now use a memory
  resolution function which just sticks the immediate address
  into rm_addr.  With cached instructions we need this.

4e091e37ea - the constructors for BX_MEM_C did not always init vector and actual_vector
to NULL.  If actual_vector points to junk when alloc_vector_aligned
  is called, it will try to free the junk, leading to memory corruption
  or crashes.

f0c9896964 Now, when you compile with --enable-guest2host-tlb, non-paged
mode uses the notion of the guest-to-host TLB.  This has the
benefit of allowing more uniform and streamlined acceleration
code in access.cc which does not have to check if CR0.PG
is set, eliminating a few instructions per guest access.
Shaved just a little off execution time, as expected.

Also, access_linear now breaks accesses which span two pages,
into two calls the the physical memory routines, when paging
is off, just like it always has for paging on.  Besides
being more uniform, this allows the physical memory access
routines to known the complete data item is contained
within a single physical page, and stop reapplying the
A20ADDR() macro to pointers as it increments them.
Perhaps things can be optimized a little more now there too...
I renamed the routines to {read,write}PhysicalPage() as
a reminder that these routines now operate on data
solely within one page.

I also added a little code so that the paging module is
notified when the A20 line is tweaked, so it can dump
whatever mappings it wants to.

7b157bbf43 - remove panic condition "memory not suitably aligned" and replace with
an allocation scheme that is guaranteed to return a block that is
  aligned correctly.
- Kevin asked me to go ahead and align the memory to 4k page boundaries,
  so I did.  If we need to change this, just change BX_MEM_VECTOR_ALIGN
  in memory/memory.h (now 4096).

31b30d562e - if ROM image could not be opened, we were doing a BX_INFO and then
a BX_EXIT.  I changed it to BX_PANIC followed by a return (just in case
  the user continues) to be more consistent with how everything else works.

3a5f338419 Integrated patches for:
- Paging code rehash.  You must now use --enable-4meg-pages to
    use 4Meg pages, with the default of disabled, since we don't well
    support 4Meg pages yet.  Paging table walks model a real CPU
    more closely now, and I fixed some bugs in the old logic.
  - Segment check redundancy elimination.  After a segment is loaded,
    reads and writes are marked when a segment type check succeeds, and
    they are skipped thereafter, when possible.
  - Repeated IO and memory string copy acceleration.  Only some variants
    of instructions are available on all platforms, word and dword
    variants only on x86 for the moment due to alignment and endian issues.
    This is compiled in currently with no option - I should add a configure
    option.
  - Added a guest linear address to host TLB.  Actually, I just stick
    the host address (mem.vector[addr] address) in the upper 29 bits
    of the field 'combined_access' since they are unused.  Convenient
    for now.  I'm only storing page frame addresses.  This was the
    simplest for of such a TLB.  We can likely enhance this.  Also,
    I only accelerated the normal read/write routines in access.cc.
    Could also modify the read-modify-write versions too.  You must
    use --enable-guest2host-tlb, to try this out.  Currently speeds
    up Win95 boot time by about 3.5% for me.  More ground to cover...
  - Minor mods to CPUI/MOV_CdRd for CMOV.
  - Integrated enhancements from Volker to getHostMemAddr() for PCI
    being enabled.

These should be pretty snappy now.  It's time to generate

fda1b874e9 Check in FETCHDECODE Caching, with changes.
Specific changes from the patch:

1.) renamed fdcache_eip to fdcache_ip, as it is using
the RIP instead of the EIP.

2.) added a Boolean array fdcache_is32 which uses is32
to determine icache hits.  Otherwise we could run 32-bit
code as 16-bit or vice versa.

  is not ideal.

565fa8ea8e - another speed boost: when not using SMP, use
BX_CPU_C bx_cpu;
     BX_MEM_C bx_mem;
  and when more than one processor, use
     BX_CPU_C    *bx_cpu_array[BX_SMP_PROCESSORS];
     BX_MEM_C    *bx_mem_array[BX_ADDRESS_SPACES];
  The changeover is controlled by BX_SMP_PROCESSORS, but there are only
  a few code changes since nearly all code uses the BX_CPU(n) and BX_MEM(n)
  macros.
- This turns out to make a 10% speed difference!  With this revision,
  the CVS version now gets 95% of the performance of the 3/25/2000
  snapshot, which I've been using as my baseline.

bdb89cd364 merge in BRANCH-io-cleanup.
To see the commit logs for this use either cvsweb or
cvs update -r BRANCH-io-cleanup and then 'cvs log' the various files.

In general this provides a generic interface for logging.

logfunctions:: is a class that is inherited by some classes, and also
.   allocated as a standalone global called 'genlog'.  All logging uses
.   one of the ::info(), ::error(), ::ldebug(), ::panic() methods of this
.   class through 'BX_INFO(), BX_ERROR(), BX_DEBUG(), BX_PANIC()' macros
.   respectively.
.
.   An example usage:
.     BX_INFO(("Hello, World!\n"));

iofunctions:: is a class that is allocated once by default, and assigned
as the iofunction of each logfunctions instance.  It is this class that
maintains the file descriptor and other output related code, at this
point using vfprintf().  At some future point, someone may choose to
write a gui 'console' for bochs to which messages would be redirected
simply by assigning a different iofunction class to the various logfunctions
objects.

More cleanup is coming, but this works for now.  If you want to see alot
of debugging output, in main.cc, change onoff[LOGLEV_DEBUG]=0 to =1.
