* Split eeprom.c into a base class base_eeprom_device and a serial-specific Aaron Giles2013-07-271-3/+1
| | | | | | | | subclass serial_eeprom_device. Moved the latter into its own file eepromser.c and significantly cleaned up/simplified the code. The new code should be functionally the same as the previous code, but expect that to change soon. As a side-effect, the size and bus width of the EEPROM is now specified in the ADD macro rather than in the interface structure.

* Move devices into a proper hierarchy and handle naming Aaron Giles2012-01-241-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and paths consistently for devices, I/O ports, memory regions, memory banks, and memory shares. [Aaron Giles] NOTE: there are likely regressions lurking here, mostly due to devices not being properly found. I have temporarily added more logging to -verbose to help understand what's going on. Please let me know ASAP if anything that is being actively worked on got broken. As before, the driver device is the root device and all other devices are owned by it. Previously all devices were kept in a single master list, and the hierarchy was purely logical. With this change, each device owns its own list of subdevices, and the hierarchy is explicitly manifest. This means when a device is removed, all of its subdevices are automatically removed as well. A side effect of this is that walking the device list is no longer simple. To address this, a new set of iterator classes is provided, which walks the device tree in a depth first manner. There is a general device_iterator class for walking all devices, plus templates for a device_type_iterator and a device_interface_iterator which are used to build iterators for identifying only devices of a given type or with a given interface. Typedefs for commonly-used cases (e.g., screen_device_iterator, memory_interface_iterator) are provided. Iterators can also provide counts, and can perform indexed lookups. All device name lookups are now done relative to another device. The maching_config and running_machine classes now have a root_device() method to get the root of the hierarchy. The existing machine->device("name") is now equivalent to machine->root_device().subdevice("name"). A proper and normalized device path structure is now supported. Device names that start with a colon are treated as absolute paths from the root device. Device names can also use a caret (^) to refer to the owning device. Querying the device's tag() returns the device's full path from the root. A new method basetag() returns just the final tag. The new pathing system is built on top of the device_t::subtag() method, so anyone using that will automatically support the new pathing rules. Each device has its own internal map to cache successful lookups so that subsequent lookups should be very fast. Updated every place I could find that referenced devices, memory regions, I/O ports, memory banks and memory shares to leverage subtag/subdevice (or siblingtag/siblingdevice which are built on top). Removed the device_list class, as it doesn't apply any more. Moved some of its methods into running_machine instead. Simplified the device callback system since the new pathing can describe all of the special-case devices that were previously handled manually. Changed the core output function callbacks to be delegates. Completely rewrote the validity checking mechanism. The validity checker is now a proper C++ class, and temporarily takes over the error and warning outputs. All errors and warnings are collected during a session, and then output in a consistent manner, with an explicit driver and source file listed for each one, as well as additional device and/or I/O port contexts where appropriate. Validity checkers should no longer explicitly output this information, just the error, assuming that the context is provided. Rewrote the software_list_device as a modern device, getting rid of the software_list_config abstraction and simplifying things. Changed the way FLAC compiles so that it works like other external libraries, and also compiles successfully for MSVC builds.
* Created new testcpu driver that shows how to develop an empty Aaron Giles2012-01-141-1/+1
| | | | | | | | | test driver that (ab)uses the core to single step a CPU executing arbitrary instructions and capturing before/after state and tracking memory. Currently this driver is always compiled, but is not referenced in mame.lst. Also updated and modernized the dummy empty driver.
* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-77/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | existing modern devices and the legacy wrappers to work in this environment. This in general greatly simplifies writing a modern device. [Aaron Giles] General notes: * some more cleanup probably needs to happen behind this change, but I needed to get it in before the next device modernization or import from MESS :) * new template function device_creator which automatically defines the static function that creates the device; use this instead of creating a static_alloc_device_config function * added device_stop() method which is called at around the time the previous device_t's destructor was called; if you auto_free anything, do it here because the machine is gone when the destructor is called * changed the static_set_* calls to pass a device_t & instead of a device_config * * for many devices, the static config structure member names over- lapped the device's names for devcb_* functions; in these cases the members in the interface were renamed to have a _cb suffix * changed the driver_enumerator to only cache 100 machine_configs because caching them all took a ton of memory; fortunately this implementation detail is completely hidden behind the driver_enumerator interface * got rid of the macros for creating derived classes; doing it manually is now clean enough that it isn't worth hiding the details in a macro
* BIG update. Aaron Giles2011-03-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove redundant machine items from address_space and device_t. Neither machine nor m_machine are directly accessible anymore. Instead a new getter machine() is available which returns a machine reference. So: space->machine->xxx ==> space->machine().xxx device->machine->yyy ==> device->machine().yyy Globally changed all running_machine pointers to running_machine references. Any function/method that takes a running_machine takes it as a required parameter (1 or 2 exceptions). Being consistent here gets rid of a lot of odd &machine or *machine, but it does mean a very large bulk change across the project. Structs which have a running_machine * now have that variable renamed to m_machine, and now have a shiny new machine() method that works like the space and device methods above. Since most of these are things that should eventually be devices anyway, consider this a step in that direction. 98% of the update was done with regex searches. The changes are architected such that the compiler will catch the remaining errors: // find things that use an embedded machine directly and replace // with a machine() getter call S: ->machine-> R: ->machine\(\)\. // do the same if via a reference S: \.machine-> R: \.machine\(\)\. // convert function parameters to running_machine & S: running_machine \*machine([^;]) R: running_machine \&machine\1 // replace machine-> with machine. S: machine-> R: machine\. // replace &machine() with machine() S: \&([()->a-z0-9_]+machine\(\)) R: \1 // sanity check: look for this used as a cast (running_machine &) // and change to this: *(running_machine *)
* Converted TMS3203X to a modern device. Aaron Giles2011-01-311-2/+1
| | | | | | Also removed redundant m_machine from the state and execute interfaces to fix ambiguity when using m_machine from within a device that inherits from these.

* Moved debugging structure away from CPUs only and attached to all Aaron Giles2010-07-061-9/+9
| | | | | | | | | | | | | | | | devices. Debugger now creates one for each device. C++-ified most debugger operations to hang off the debugging class, and updated most callers. This still needs a little cleanup, but it fixes most issues introduced when the CPUs were moved to their own devices. Got rid of cpu_count, cpu_first, cpu_next, etc. as they were badly broken. Also removed cpu_is_executing, cpu_is_suspended, cpu_get_local_time, and cpu_abort_timeslice. Some minor name changes: state_value() -> state() state_set_value() -> set_state()

* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-0/+630
performance as a result of this change. 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]
