ea7334bfab Sector size option implemented in the USB disk code. The sector size value must
be specified as a USB port option (e.g. 'sect_size:1024'). The values 512, 1024
and 4096 are supported. If not specified, it defaults to 512.
TODO: ATA disk (harddrv code), BIOS, bximage.

657cd05c0a Continued preparing hard disk sector size option in the hdimage code.
- 'flat' mode: disk image size must be multiple of sector size.
- 'concat' mode: each disk image size and lseek() offset must be multiple of
   sector size.
- 'sparse' mode: page size and lseek() offset must be multiple of sector size.
- TODO: 'growing', 'undoable' and 'volatile' mode: redolog_t class is still
  based on 512-byte blocks.
- TODO: 'vbox', 'vmware3', 'vmware4', 'vpc' and 'vvfat' mode have a builtin
  geometry. If other sector sizes are supported, it should be handled correctly.
- harddrv code now reports current sector size, but still panics for now.
- TODO: harrdrv and USB disk code, bximage, BIOS.

db95a54238 Prepared config interface for a hard disk sector size option.
This code is based on the initial patch by Ben Lunt with some modifications:
using enum parameter, extra parser handler and cdrom handling not necessary,

e639d9dd29 Report AGP model in PCI status, new PCI capabilities and strapInfo register.
AGP specific features are not present yet.

8952c144bd Some work on the i440BX chipset and related changes.
- Fixed PCI BAR initialization (now using memset()).
  - Fixed reset failure (set all PAM memory types to ROM).
  - Added stub for the AGP aperture (register BAR #0, handle APSIZE and read
    GART entry in read/write handlers).
  - Added some more PCI register defaults and write masks.
  - Fixed a warning in the ES1370 code.
  - Voodoo Banshee: set up PCI subsystem ID depending on bus and model.
  - Volatile BIOS write support must also be present in ISA BIOS memory.

73bc76072e Added support for assigning a device (banshee or voodoo3) on Bochs PCI slot #5
to AGP if chipset i440BX is selected. AGP-specific features are not implemented
yet.

e7093e74d8 Started implementing the i440BX PCI/AGP chipset.
- Added new PCI chipset choice for the i440BX AGPset. Some basic work is done,
  but AGP support is not present yet.
- Added new class for the "virtual" PCI-to-PCI bridge that should manage the
  secondary bus (AGP). Since this device must appear with device number #1 at
  the primary bus, it was required to change the PCI device numbers for the
  i440BX case. Moved the PIIX4 module to device number #7. The presence of the
  PCI base address regions now depends on the header type as expected.
- Since the Bochs BIOS cannot handle the modified PCI device layout, all tests
  continued with an external BIOS designed for this chipset (GA-6BA_F1.bin).
  This BIOS requires additional changes in some devices.
- ACPI: Return value 0 for some status registers and the GPI registers.
- CMOS: Since the PIIX4 supports a 256 byte CMOS RAM, prepared support for it
  and enable it in case a 256 byte CMOS image is used.
- PCI: The device numbers for 4 slots starting at #8. The 5th slot could be
  used for AGP when available.

05da2a4dff Added basic support for the Voodoo3 model (Banshee plus secondary TMU).
Using a temporary subsystem ID, since I haven't found a VGABIOS ROM image for
the PCI version and Bochs doesn't support AGP yet. After modifying Voodoo3.inf
the driver could be installed successfully in Win95/98 and the Voodoo3 works as
expected (same issues as the Banshee model).
Removed BX_ERROR message about setting undocumented srcXY register bits. They
seem to have no effect on the emulation and could be ignored.

87145baf61 Rewrite of the PCI base address (BAR) handling to reduce code duplication.
- Added new structure bx_pci_bar_t that contains all parameters related to the
  PCI BARs (type, size, address and r/w handlers).
- Added new methods init_bar_io() and init_bar_mem() to set up the new structure
  in the pci device init code.
- Added new method pci_write_handler_common() to handle writes to the normal
  BARs and the ROM BAR. Writes to other registers are forwarded to the device
  specific PCI write handlers. Removed BAR and ROM BAR handling from the
  specific code.
- Added new method pci_bar_change_notify() to execute specific code after BAR
  update (vga, ne2k).
- Moved normal BAR handling to method after_restore_pci_state().
- Store pointer to PCI device name in bx_pci_device_c and use it for i/o setup.

but bx_param_bytestring_cis not matching that concept (or probably will continue to inherit from bx_param<string>)

  - Display errors in 16 bpp mode after leaving 3D mode.
  - Display errors in 16 bpp mode in case debug messages are turned on (timing).
  - Voodoo2 3D demo "donut" still fails.
  - Bochs crashes on Windows host (MSVC in some cases, MSYS2 64-bit build also
    reported, but not yet reproduced.
- TODO list:
  - Remaining 2D stuff: polygon fill, stretching functions.
  - Move Banshee stuff to separate files.
  - Add Voodoo3 support (it's an improved Banshee card).

d5e2fbed00 Some work on the Voodoo Banshee emulation.
- Fixed alignment for unpacked monochrome source data in case the calculated
  required amount of data for one row is more than the given source pitch.
  In even rows the leftmost pixel comes from the LSB bit #7 as expected.
  In odd rows the whole row is aligned to the next dword boundary (the rightmost
  pixel comes from the MSB bit #0). This alternating alignment is not documented,
  but fixes some bitmaps (e.g. Win95 login / logout dialogs).
- Fixed calculation of host-to-screen data size for the pixel alignment > 0 and
  color depth > 8.
- Added minimal support for pixel format conversion (32/24 to 16).

47f3936de2 Some work on the Voodoo Banshee emulation.
- Added Banshee specific registers in register_w() since they use the same
  addresses as the Voodoo2 CMDFIFO config registers in register_w_common().
  Now the fullscreen 3D mode is basicly working. The display flickers sometimes
  and the desktop is possibly unusable after leaving 3D mode. This may be
  caused by the still incorrect CMDFIFO implementation.
- Split the host-to-screen method in two ones: one for the pattern case (ternary
  ROPs) and one optimized for the standard case (binary ROPs).
- Improved the foreground/background color handling for bitblt operations.

dd694757f4 Attempt to fix the calculation of the source pitch and the total amount of
dwords required for host-to-screen operations. There are no related error
messages in the log when I test 8, 24 and 32 bpp modes. There are still display
errors caused by buggy code, incorrect CMDFIFO implemenation or undocumented
features. The 16 bpp mode is still unusable possibly caused by CMDFIFO. 3D mode
testing cannot start before this mode is okay.

c81df659c1 Some work on the Voodoo Banshee BitBlt code.
- Implemented ternary raster operations. With 3 binary input values we have 8
  possible combinations und the ROP code is the binary representation of the
  result table. Instead of implementing cascades of binary operations at byte
  level, we simply build a 3-bit value from D, S and P. This is the bit number
  of the ROP code to use as the result. This is performed for each bit of color
  data. We still keep the existing binary operations at byte level, since the
  code is faster for that case.
- Inplemented the "row #0 only" flag handling in pattern fill operations. This
  flags seems to have an undocumented effect on the source pitch of
  host-to-screen operations. This issue needs to be investigated.
- TODO: Some bits of the srcXY register seem to have an undocumented effect on
  host-to-screen operations, too.

da48346f9d Implemented combined PCI / memory FIFO. This is required for running Voodoo1
games / demos correctly on the Voodoo2 model. I noticed a small slowdown
(2 or 3 percent) on the Voodoo1.

e063d282ac Voodoo2 CMDFIFO fix and cleanup.
- Fixed probing the CMDFIFO with Voodoo output disabled (send FIFO wakeup
  directly, otherwise driven by vertical retrace).
- Use the CMDFIFO member 'enabled' instead of reading the fbiInit7 register bit.
- TODO: The Voodoo2 freeze when testing a Voodoo1 demo is still not fixed.

7c3dafc7f5 Some Voodoo emulation fixes.
- voodoo_init() must be called after initializing FIFO mutex.
- The 'op_pending' counter must be reset after resetting FIFOs.
- Fixed an MSVC warning and removed obsolete comment.
- FIXME: There are still some conditions that can freeze the Voodoo display.

1f85292418 Implemented memory FIFO to speed up the Voodoo1 emulation. The PCI FIFO with
it's 64 entries is still not present, since it makes the emulation a few
percent slower due to the overhead of the FIFO code. The memory FIFO has 64k
entries and makes a speedup of around 75 % possible.

2a55ba0a39 Merge set of debugger improvements by Doug Gale <doug16k>
Here is his original comment:

I have made several improvements in the debugger.
I have fixed several issues with proper handling of 64-bit addresses, and added support for 64 bit symbols.
I also have added several symbol lookups.

e187f3907a Removed Voodoo realtime option. Since the gui screen update timing is now
controlled by the 'vga' option and Voodoo2 CMDFIFO thread has the best
performance with realtime mode disabled, this option is now obsolete.

9a1668ac36 First version of the Voodoo2 CMDFIFO thread using "pthread cond" code on
non-WIN32 platforms instead of BX_MSLEEP(). The donut demo is once again a
little bit slower, but on other tests the IPS values are still okay. Cleaned
up the code a little bit and added save/restore stuff for the new code.

6361386e8b Reverted BX_LOCK/BX_UNLOCK changes from previous commit (don't lock CMDFIFO

6265976a2c Some work on the Voodoo2 CMDFIFO support.
- Added CMDFIFO thread similar to the sound output thread.
- split register write function in 2 functions: register_w_common() handles
  the CMDFIFO writes and valid registers in CMDFIFO mode. It forwards write
  accesses to other registers to register_w() (Voodoo1 and non-CMDFIFO mode).
  The CMDFIFO thread also calls register_w() when processing data.
- The CMDFIFO thread processes all data, but it does not yet execute type 3
  requests (extended triangle generator missing).
- TODO #1: implement Voodoo2 specific triangle functions (for CMDFIFO).
