6566116a01 - added BX_DEBUG, BX_INFO, BX_PANIC macros 
- BX_DEBUG outputs to the INFO port till we can easily choose debug output on a per-device basis
- BX_DEBUG are only generated if DEBUG_ROMBIOS is defined to 1
- do not panic on unsupported function in int13, only output info message
- fixed a bug on boot signature check never done on floppy/harddisk and always on floppy images on cd
- the boot signature check on harddisks is always done
- the boot signature check on cdroms (either direct boot or floppy images) is never done
- the boot signature check on floppies is conditionnal to CMOS reg 0x38 (configuration floppy_bootsig_check)
- moved PIC initialization before calling optional rombios init functions (feature request [ 541908 ])

2f37ec16ea - added a DEBUG port for rombios (0x0403) and vgabios (0x0503) 
- added a INFO port for rombios (0x0402). Kept the legacy INFO port at 0xfff0 for now

cd50268e2f - added a floppy_bootsig_check option to .bochsrc that will be used to enable/disable the 0xaa55 signature check ONLY for floppy-boot 
- stored the boot signature check flag in cmos reg 0x38
- the rombios that is able to handle that flag will be uploaded later

462871fd3a - Improvements for dimension_update() in text mode and text_update() 
- The emulated vga card issues a dimension_update() using the real
    screen dimensions and the real font height.

  - The gui selects a font with the requested height or it recalculates
    the screen height if the font height is not available.

  - The text_update() function uses a new variable 'ncols' instead of the
    fixed value of 80 for the number of text columns.

  I have tested the changes with X11/Linux, SDL, wxGTK and win32. The changes
  in the other guis are not tested yet.

bb398122d6 - fix up some missing end tags as suggested by Guilhem BONNEFILLE (guyou) 
in a source forge patch.  I didn't change the entity that includes
  "../include/defs.sgm" because then it stops working for me.

2f69a74616 - commit TUN/TAP patch, though I can't really test it. I can verify that if 
you don't have if_tun.h the configure script does not enable TUN/TAP.

2bac9a8f0e - remove dependency on /usr/include/math.h which is platform dependent.

13bb61838e - add comments describing how blur-translate works 2002-04-17 22:51:58 +00:00
Bryce Denney
8dbf420ac5 - move common definitions into blur-translate.h, which is included by 
both blur-translate.c and all translated code when it is compiled.
- use DO_*() macros in blur-translate.h to implement the switch() statement
  in the emulate function, so that the same code is really used for both
  emulation and translation.

59572dcbcf - add command line args to let you choose reference implementation, 
emulation, or translation.
- allow multiple timers
- report time required to translate and compile

16ec33a673 - add blur-translate, which has a somewhat cleaned-up interface to the 
dynamic translation.  I added a structure called a CodeBlock that
  points to the instruction list, the dynamic library handle, and the
  function pointer.  To translate a CodeBlock, just call
  translate_block (block).

5fd7c60491 - add BLUR_DYNAMIC_TRANSLATE3 which generates C code, compiles it into 
a dynamic library, loads it, and runs it.  Requires libtool.

8ad83d2588 - add -DBLUR_DYNAMIC_TRANSLATE3 which generates code, compiles it into 
a shared library, and then dlopens it!

2d87c60a34 - add BLUR_DYNAMIC_TRANSLATE2, which produces code that inserts the 
loop updates into the translated function so that the loop can be
  optimized.

ac8a29fb3d - use local variable for load_ptr,store_ptr, now that they exist. 
- add BLUR_DYNAMIC_TRANSLATE1, a simple code generator that writes to
  translate1.c
- add BLUR_DYNAMIC_TRANSLATE1_TEST that is (statically) linked with
  translate1.c

2a3524e2d2 - all target was causing blur-opcode to be compiled, when it shouldn't. 
I know, the makefile is a total mess but it works for now.

5605922ddc - add blur-opcode and all its variations into the Makefile 2002-04-17 02:31:58 +00:00
Bryce Denney
0995c43dd6 - make the blur look a lot more like an instruction emulator. I defined 
a tiny instruction set that can be used to implement a blur filter.
  Experiment with switch, function pointer, and a few different
  forms of "translated" code.

50231039fc - add blur_unroll_inner, which unrolls the x2 and y2 loops into 
one long statement.

63da4808e5 - fix bug in call to blur_func, causing us to get wrong answer 
- dump_array was dumping the input array instead of the output array.
  That didn't make for a very good regression test.
- add warning in BLUR_USE_SWITCH code since it doesn't do the same operation
  as the others.

as number of instructions.  Oops.
