ea18b29e12 - geometry autodetection for 'flat' hard disk images added. It works with all
images created with bximage (heads = 16, sectors per track = 63)
- size check for 'flat' hard disk images added. The image size is now compared
  with the size calculated from the geometry.

f43d2fe3e9 - backport of the BRANCH_HARDDISK_MODES to the main branch.
You can now choose for each disk on the ata interfaces the
  disk mode, between :
    - flat : one file flat layout
    - concat : multiple files layout
    - external : developer's specific, through a C++ class
    - dll : developer's specific, through a DLL
    - sparse : stackable, commitable, rollbackable
    - vmware3 : vmware3 disk support
    - undoable : flat file with commitable redolog
    - growable : growing file
    - volatile : flat file with volatile redolog
    - z-undoable : gziped flat file with commitable redolog
    - z-volatile : gziped flat file with volatile redolog
  A new "bxcommit" utility can merge commitable redologs to
  flat images.

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.

5e520261db Add plugin support to Bochs by merging all the changes from the
BRANCH_PLUGINS branch!

Authors:
  Bryce Denney
  Christophe Bothamy
  Kevin Lawton (we grabbed a lot of plugin code from plex86)
Testing help from:
  Volker Ruppert
  Don Becker (Psyon)
  Jeremy Parsons (Br'fin)

The change log is too long to paste in here.  To read the change log, do
  cvs log patches/patch.final-from-BRANCH_PLUGINS.gz

All the changes and a detailed description are contained in a patch
called patch.final-from-BRANCH_PLUGINS.gz.  To look at the complete
patch, do
  cvs upd -r1.1 patches/patch.final-from-BRANCH_PLUGINS.gz

Then you will have a local copy of the patch, which you can gunzip and
play with however you want.

957e1b5abe - fix bug [ 625676 ] VC++ do not support S_ISBLK. Block devices are not supported on win32 anyway. 2002-10-21 23:51:49 +00:00
Bryce Denney
9297b17797 - in main.cc make the bochsrc parser a little more lenient about
empty pathnames, zero cylinders, etc.  It doesn't seem fair to allow
  people to write out bochsrcs that they cannot read back in without
  patching them up by hand!
- in harddrv.cc add the equivalent checks with BX_PANICs so that at least
  we don't start simulating with incomplete device configuration.
- make a few error messages more clear
- modified: main.cc iodev/harddrv.cc

c3a74d4da0 Integrated patches/patch.promise-dc2300-vlbide from Christophe Bothamy.
From his patch file text:

  > This patch adds Promise DC2300 VLB IDE Support.
  > You may find msdos and win95 drivers on the net. Look for
  > P2300W95.ZIP and DC2300VLBIDEver260b.ZIP.
  >
  > The good news is that now win95 natively sees my cdrom,
  > and that the disks are not in msdos compatibility mode any more.

I got Win95 running with 32-bit paging/filesystem using the
  recommended driver and these patches.  Since the patches did
  such a good job bracketing code modifications with a #define,
  they might as well become part of the current CVS code.

414e97bc32 Enhanced the repeat IO accelerations (enabled by --enable-repeat-speedups)
to request bulk IO operations to IO devices which are bulk IO aware.
Currently, I modified only harddrv.cc to be aware.  I added some
fields to the bx_devices_c class for the IO instructions to
place requests and receive responses from the IO device emulation.
Devices except the hard drive, don't monitor these fields so they
respond as normal.  The hard drive now monitors these fields for
bulk requests, and if enabled, it memcpy()'s data straight from
the disk buffer to memory.  This eliminates numerous inp/outp calling
sequences per disk sector.

I used the fields in bx_devices_c so that I would not have to
disrupt most IO device modules.  Enhancements can be made to
other devices if they use high-bandwidth IO via in/out instructions.

7fdc7303c2 - add "void reset(unsigned type)" method to every I/O device.
Some devices already had one.  Some I had to add an empty one.
  I did a little cleaning of init() methods to make them more uniform
  but generally I left them alone.
- I also put these exact diffs into a patch "patch.iodev-add-reset"
  in case I want to revert these changes for some reason, for example
  if they break an old patch.  It should be deleted after a while.

b84c82e80c - changed the floppy_bootsig_check syntax to be more logical. the syntax is now :
floppy_bootsig_check: disabled=[0|1]. It is not disabled by default.
  Sorry for any inconvenience it could cause
- changed the default (if cmos reg is 0) behavior for the floppy boot signature
  check, so the new bios is compatible with older bochs binaries (useful if we
  want to use the new bios when we release 1.4.1) :
  1 : disabled
  0 : enabled

a9204c53f0 - make hard disk code return error codes when data is not available instead
of just panicing.  In particular, if the logical sector is out of bounds
  or the disk image cannot be read/written at the desired offset, we now
  abort the ATA command and return an error code.  Many of the old BX_PANIC
  messages are turned to BX_ERROR, so they will still appear in the
  log, but now the device model will try to communicate this fact to
  the OS instead of simply giving up.

ec0fbf18bc - convert nearly all bx_options to parameter form. All options that have
been converted into parameters temporarily have the letter "O" appended
  to their name.  I don't want to keep it this way, but it has helped
  in the conversion process because the compiler refuses to compile the
  old uses of the name.  Before I started using the "O" trick, there were
  many bugs like this:   if (bx_options.diskc.present) {...}
  This was legal with the new parameters, but it was testing whether the
  parameter structure had been created, instead of testing the value of
  the present parameter.  Renaming present to Opresent turns this into
  a compile error, which points out the incorrect use of the param.
- the "--disable-control-panel" no longer works, I'm afraid.  I can no
  longer support this and continue progress.

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.
