c12c8324dc Added config parameter to set up advanced PCI options as comma-separated
values. Now it is possible to disable ACPI or HPET in case the i440FX chipset
is selected.

1ae98a9f66 Unified code for mapping PCI slot to device number. By default the first slot
is mapped to device number #2, but for the i440BX chipset we are using #8
(expected by real BIOS when testing and some timer later added support for it
in Bochs BIOS).

c10e8feea6 Added support for driving the speaker line directly with the speaker gate, but
the square wave generator disabled. This feature has been used by old demos and
games to play digitized sound before soundcards with DSP became popular.

7412ebc07b Added new macros BX_DEBUG_PCI_READ and BX_DEBUG_PCI_WRITE to unify the debug
output of PCI config space handlers.
Banshee: some PCI register fixes.

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.

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.

d25e85c21a Preparing improved VGA extension support and some VGA / Cirrus cleanups.
- Treat VGA extension name other than "none", "vbe" or "cirrus" as a VGA
  compatible device plugin and try to load it.
- Added new plugin type PLUGTYPE_VGA for such a plugins (interally handled like
  a core plugin).
- Added panic in devices init for the case no VGA compatible plugin is present.
- Added new method vga_redraw_area() that handles the non-VGA and null size
  case. The specific method redraw_area() is called otherwise.
- Moved init_systemtimer() call from extension code to init_standard_vga().
- TODO: Implement VGA subsystem in the Voodoo code to test the new feature.
  Voodoo Banshee 2D accelerator code needs to be written to make this really
  useful.

6dba96d10a Some changes related to the PCI ROM handling.
- Added support for setting memory write handler to NULL (ROM case).
- Added new PCI device method after_restore_pci_state(). It currently handles
  the PCI ROM case only (could be extended).

89654a4beb Prepared devices and timer code for HPET support
- PIT / CMOS: added methods to control IRQ generation (for HPET legacy mode).
- Added method for activating timer with nanosecond value.
- Removed unused declaration in the keyboard code.

e023b5896f Partial rewrite of the optional keyboard handling. Now the BX_KEY_* events are
directly sent to the optional keyboard (USB keypad). It is now independent
from the legacy keyboard and the check for supported keys is simplified. The
legacy keyboard still receives the unhandled key event, but now sent from the
common devices code.

76b54ecb61 Renamed bx_pci_device_stub_c to bx_pci_device_c and derive it now from class
bx_devmodel_c. The early version of the combined vga / svga_cirrus code
required the now obsolete implementation. Some related cleanups in the
devices code.

d46a9b7205 Some work on the PCI devices code.
- Since the pci_read_handler() method is identical in most devices, move it
  to the base class to reduce code duplication. Only the 'pcidev' device has
  it's own implementation (NOTE: it is not maintained yet).
- Minor other fixes and cleanups in some PCI devices.

b1e8a6369c Some work on the sound module handling and the SB16 midi file output.
- Added the capability to load up to 4 sound drivers and added methods to
  get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
  service of the 'file' driver is used. Removed obsolete midi file handling.

4eae421272 Graphics snapshot feature re-implemented for the new graphics API
- graphics_tile_info() split into a common and specific part
- store snapshot mode in structure bx_svga_tileinfo_t
- in snapshot mode, display adapters copy raw data to buffer
- rewrite of the trigger_timer() code to make it work in all cases
- added new class bx_nonvga_device_c to make forwarding refresh requests to the
  Voodoo adapter possible
2012-10-25 15:53:04 +00:00
Volker Ruppert
1fd6745aea Started rewrite of the gui code to make the graphics snapshot independent from
the display adapter code. When ready, the common gui code should handle it
completely. The snapshot handler should set a flag 'snapshot_mode' and then it
should force a display update. The graphics update code should be redirected to
some code that 'draws' to a snapshot buffer. These first steps are done:

- store some guest display settings in the gui code (text / graphics switch,
  x / y resolution and bpp)
- split 8 bpp palette update code in a common and a specific part and store the
  palette values in the gui code

c6a9f8eb0d - added the capability to transfer more then one byte per ISA DMA cycle.
- use this feature for floppy read and write operations. This does not mean that
  the floppy now works faster than realtime, but it reduces the number of DMA
