Do not panic; report issues to the list in the short term and I will look into them. There are probably also some details I forgot to mention. Please ask questions if anything is not clear. NOTE: This is a major internal change to the way devices are handled in MAME. There is a small impact on drivers, but the bulk of the changes are to the devices themselves. Full documentation on the new device handling is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics Defined two new casting helpers: [Aaron Giles] downcast<type>(value) should be used for safe and efficient downcasting from a base class to a derived class. It wraps static_cast<> by adding an assert that a matching dynamic_cast<> returns the same result in debug builds. crosscast<type>(value) should be used for safe casting from one type to another in multiple inheritance scenarios. It compiles to a dynamic_cast<> plus an assert on the result. Since it does not optimize down to static_cast<>, you should prefer downcast<> over crosscast<> when you can. Redefined running_device to be a proper C++ class (now called device_t). Same for device_config (still called device_config). All devices and device_configs must now be derived from these base classes. This means each device type now has a pair of its own unique classes that describe the device. Drivers are encouraged to use the specific device types instead of the generic running_device or device_t classes. Drivers that have a state class defined in their header file are encouraged to use initializers off the constructor to locate devices. [Aaron Giles] Removed the following fields from the device and device configuration classes as they never were necessary or provided any use: device class, device family, source file, version, credits. [Aaron Giles] Added templatized variant of machine->device() which performs a downcast as part of the device fetch. Thus machine->device<timer_device>("timer") will locate a device named "timer", downcast it to a timer_device, and assert if the downcast fails. [Aaron Giles] Removed most publically accessible members of running_device/device_t in favor of inline accessor functions. The only remaining public member is machine. Thus all references to device->type are now device->type(), etc. [Aaron Giles] Created a number of device interface classes which are designed to be mix- ins for the device classes, providing specific extended functionality and information. There are standard interface classes for sound, execution, state, nvram, memory, and disassembly. Devices can opt into 0 or more of these classes. [Aaron Giles] Converted the classic CPU device to a standard device that uses the execution, state, memory, and disassembly interfaces. Used this new class (cpu_device) to implement the existing CPU device interface. In the future it will be possible to convert each CPU core to its own device type, but for now they are still all CPU devices with a cpu_type() that specifies exactly which kind of CPU. [Aaron Giles] Created a new header devlegcy.h which wraps the old device interface using some special template classes. To use these with an existing device, simply remove from the device header the DEVICE_GET_INFO() declaration and the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro. In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping existing sound devices into new-style devices, and a DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the token and inline_config members to the legacy device class, as these are not used in modern devices. [Aaron Giles] Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER) from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to simply SCREEN. The various global functions that were previously used to access information or modify the state of these devices are now replaced by methods on the device classes. Specifically: video_screen_configure() == screen->configure() video_screen_set_visarea() == screen->set_visible_area() video_screen_update_partial() == screen->update_partial() video_screen_update_now() == screen->update_now() video_screen_get_vpos() == screen->vpos() video_screen_get_hpos() == screen->hpos() video_screen_get_vblank() == screen->vblank() video_screen_get_hblank() == screen->hblank() video_screen_get_width() == screen->width() video_screen_get_height() == screen->height() video_screen_get_visible_area() == screen->visible_area() video_screen_get_time_until_pos() == screen->time_until_pos() video_screen_get_time_until_vblank_start() == screen->time_until_vblank_start() video_screen_get_time_until_vblank_end() == screen->time_until_vblank_end() video_screen_get_time_until_update() == screen->time_until_update() video_screen_get_scan_period() == screen->scan_period() video_screen_get_frame_period() == screen->frame_period() video_screen_get_frame_number() == screen->frame_number() timer_device_adjust_oneshot() == timer->adjust() timer_device_adjust_periodic() == timer->adjust() timer_device_reset() == timer->reset() timer_device_enable() == timer->enable() timer_device_enabled() == timer->enabled() timer_device_get_param() == timer->param() timer_device_set_param() == timer->set_param() timer_device_get_ptr() == timer->get_ptr() timer_device_set_ptr() == timer->set_ptr() timer_device_timeelapsed() == timer->time_elapsed() timer_device_timeleft() == timer->time_left() timer_device_starttime() == timer->start_time() timer_device_firetime() == timer->fire_time() Updated all drivers that use the above functions to fetch the specific device type (timer_device or screen_device) and call the appropriate method. [Aaron Giles] Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE to specifically pass in a screen_device object. [Aaron Giles] Defined a new custom interface for the Z80 daisy chain. This interface behaves like the standard interfaces, and can be added to any device that implements the Z80 daisy chain behavior. Converted all existing Z80 daisy chain devices to new-style devices that inherit this interface. [Aaron Giles] Changed the way CPU state tables are built up. Previously, these were data structures defined by a CPU core which described all the registers and how to output them. This functionality is now part of the state interface and is implemented via the device_state_entry class. Updated all CPU cores which were using the old data structure to use the new form. The syntax is currently awkward, but will be cleaner for CPUs that are native new devices. [Aaron Giles] Converted the okim6295 and eeprom devices to the new model. These were necessary because they both require multiple interfaces to operate and it didn't make sense to create legacy device templates for these single cases. (okim6295 needs the sound interface and the memory interface, while eeprom requires both the nvram and memory interfaces). [Aaron Giles] Changed parameters in a few callback functions from pointers to references in situations where they are guaranteed to never be NULL. [Aaron Giles] Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles] Reorganized the token parsing for machine configurations. The core parsing code knows how to create/replace/remove devices, but all device token parsing is now handled in the device_config class, which in turn will make use of any interface classes or device-specific token handling for custom token processing. [Aaron Giles] Moved many validity checks out of validity.c and into the device interface classes. For example, address space validation is now part of the memory interface class. [Aaron Giles] Consolidated address space parameters (bus width, endianness, etc.) into a single address_space_config class. Updated all code that queried for address space parameters to use the new mechanism. [Aaron Giles]
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is now separate from runtime device state. I have larger plans for devices, so there is some temporary scaffolding to hold everything together, but this first step does separate things out. There is a new class 'running_device' which represents the state of a live device. A list of these running_devices sits in machine->devicelist and is created when a running_machine is instantiated. To access the configuration state, use device->baseconfig() which returns a reference to the configuration. The list of running_devices in machine->devicelist has a 1:1 correspondance with the list of device configurations in machine->config->devicelist, and most navigation options work equally on either (scanning by class, type, etc.) For the most part, drivers will now deal with running_device objects instead of const device_config objects. In fact, in order to do this patch, I did the following global search & replace: const device_config -> running_device device->static_config -> device->baseconfig().static_config device->inline_config -> device->baseconfig().inline_config and then fixed up the compiler errors that fell out. Some specifics: Removed device_get_info_* functions and replaced them with methods called get_config_*. Added methods for get_runtime_* to access runtime state from the running_device. DEVICE_GET_INFO callbacks are only passed a device_config *. This means they have no access to the token or runtime state at all. For most cases this is fine. Added new DEVICE_GET_RUNTIME_INFO callback that is passed the running_device for accessing data that is live at runtime. In the future this will go away to make room for a cleaner mechanism. Cleaned up the handoff of memory regions from the memory subsystem to the devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Please note: regression testing is in progress, but the first round of glaring regressions have already been taken care of. That said, there is likely to be a host of regressions as a result of this change. Also note: There are still a few rough edges in the interfaces. I will try to clean them up systematically once the basic system is working. All sound chips are now proper devices. Merged the sound chip interface into the device interface, removing any differences (such as the whole ALIASing concept). Modified every sound chip in the following ways: * updated to match the device interface * reduced read/write handlers down to the minimal number * added the use of get_safe_token() for ensuring correctness * other minor cleanup Removed the custom sound device. The additional work to just make custom sound cases into full devices is minimal, so I just converted them all over to be actual devices. Vastly simplified the sound interfaces, removing the ghastly sndti_* business and moving everyone over to using tags for sound identity. sndintrf, like cpuintrf, is now just a header file with no implementation. Modified each and every driver that references a sound chip: * all memory maps explicitly reference the targeted device via AM_DEVREAD/AM_DEVWRITE/AM_DEVREADWRITE * 16-bit and 32-bit accesses to 8-bit chips no longer use trampoline functions but instead use the 8-bit AM_DEVREAD/WRITE macros * all references to sound chips are now done via tags * note that these changes are brute force, not optimal; in many cases drivers should grab pointers to devices in MACHINE_START and stash them away

It makes the treatment of SOUND_xxx the same as that of CPU_xxx. That is, they are function pointers to the SND_GET_INFO routine for the sound. The first patch just adds some missing include files and modifies a few cases where a sound_type was used as an integer. This could go in now. The second patch then adds the needed #defines to all the sound headers (it assumes the previous patch I sent to add the SND_GET_INFO declarations was applied), and modifies the sound code accordingly. It also moves the sound clock to the device object. Note that the dummy sound core is removed entirely. I cheated a bit and made VERIFY_SNDTI also declare and fill in the sndnum, making this an INLINE function would probably be more appropriate, but all of this code's days are numbered. There may be some performance loss in drivers that expect sndti_xxx routines to be fast, since sound_matrix has been removed. The performance however should be similar to looking up items in a devicelist, so those drivers will have to adjust eventually. ~aa

It also makes a handful of other header declaration fixes in emu/sound, and makes one SND_RESET routine static. Note: votrax.h is a new include file altogether. ~aa
