| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | loader rewrite, which is still in progress....) Replaced mamedriv.c with a new driver list mechanism that is generated by the build tools. The emulator core now expects the presence of a file called src/$(TARGET)/$(SUBTARGET).lst which is just a raw list of driver names, one per line. C and C++ comments are still permitted. This file is parsed by a new build tool makelist which extracts the driver names, sorts them, and generates a file called drivlist.c, which is consumed by the core. [Aaron Giles] Added new osdcore function osd_malloc_array() which is identical to osd_malloc() but obviously hints that the underlying allocation is for an array. Updated all callers to use the appropriate form. Modified the Windows allocator to only use guard pages for array-style allocations, allowing us to enable them once again in debug builds. [Aaron Giles] Created new static class driver_list to wrap accesses to the list of available drivers. Improved speed of driver lookups by relying on the presorting done by makelist. [Aaron Giles] Created helper class driver_enumerator as a helper for iterating through the list of drivers. This class supports basic filtering and iteration, and also serves as a temporary cache of machine_configs. [Aaron Giles] Created cli_frontend object to wrap all the CLI handling code in clifront.c. Updated/simplified all the code to take advantage of the driver_enumerator. [Aaron Giles] Created media_auditor object to wrap all the auditing functions in audit.c. Updated all users to the new interface. Note that the new auditing mechanism is slightly out of sync with the romload code in terms of finding ROMs owned by devices, so it may mis-report some issues until the new ROM loading code is in. [Aaron Giles] Added concept of a per-device searchpath. For most devices, their searchpath is just the short name of the device. For driver_devices, the searchpath is driver[;parent[;bios]]. This searchpath will eventually be used by the rom loader to find ROMs. For now it is used by the media auditor only. [Aaron Giles] Created info_xml_creator object to wrap all the info generation functions in info.c. Converted the file to C++ and cleaned up the input processing code. [Aaron Giles] (not for whatsnew ... Known issues: auditing of CHDs appears busted, and debug builds report unfreed memory if you use the built-in game picker)
* 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 *)
* Created new enum type address_spacenum for specifying an address Aaron Giles2011-03-271-4/+4
| | | | | | | | | | | | space by index. Update functions and methods that accepted an address space index to take an address_spacenum instead. Note that this means you can't use a raw integer in ADDRESS_SPACE macros, so instead of 0 use the enumerated AS_0. Standardized the project on the shortened constants AS_* over the older ADDRESS_SPACE_*. Removed the latter to prevent confusion. Also centralized the location of these definitions to memory.h.

* Massive memory system change. This is another step along the path toward Aaron Giles2010-08-191-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | supporting cleaner implementations of drivers in the explicitly OO world. Expect a follow-on of several more changes to clean up from this one, which deliberately tried to avoid touching much driver code. Converted address_space to a class, and moved most members behind accessor methods, apart from space->machine and space->cpu. Removed external references to 8le/8be/16le/16be/32le/32be/64le/64be. All external access is now done via virtual functions read_byte()/read_word()/etc. Moved differentiation between the endianness and the bus width internal to memory.c, and also added a new axis to support small/large address spaces, which allows for faster lookups on spaces smaller than 18 bits. Provided methods for most global memory operations within the new address_space class. These will be bulk converted in a future update, but for now there are inline wrappers to hide this change from existing callers. Created new module delegate.h which implements C++ delegates in a form that works for MAME. Details are in the opening comment. Delegates allow member functions of certain classes to be used as callbacks, which will hopefully be the beginning of the end of fetching the driver_data field in most callbacks. All classes that host delegates must derive from bindable_object. Today, all devices and driver_data do implicitly via their base class. Defined delegates for read/write handlers. The new delegates are always passed an address_space reference, along with offset, data, and mask. Delegates can refer to methods either in the driver_data class or in a device class. To specify a callback in an address map, just use AM_READ_MEMBER(class, member). In fact, all existing AM_ macros that take read/write handlers can now accept delegates in their place. Delegates that are specified in an address map are proto-delegates which have no object; they are bound to their object when the corresponding address_space is created. Added machine->m_nonspecific_space which can be passed as the required address_space parameter to the new read/write methods in legacy situations where the space is not provided. Eventually this can go away but we will need it for a while yet. Added methods to the new address_space class to dynamically install delegates just like you can dynamically install handlers today. Delegates installed this way must be pre-bound to their object. Moved beathead's read/write handlers into members of beathead_state as an example of using the new delegates. This provides examples of both static (via an address_map) and dynamic (via install_handler calls) mapping using delegates. Added read/write member functions to okim6295_device as an example of using delegates to call devices. Updated audio/williams.c as a single example of calling the device via its member function callbacks. These will be bulk updated in a future update, and the old global callbacks removed. Changed the DIRECT_UPDATE_CALLBACKs into delegates as well. Updated all users to the new function format. Added methods on direct_read_data for configuring the parameters in a standard way to make the implementation clearer. Created a simple_list template container class for managing the common singly-linked lists we use all over in the project. Many other internal changes in memory.c, mostly involving restructuring the code into proper classes.
* Return to type safety. Changed address maps back into functions that build Aaron Giles2010-08-011-2/+2
| | | | | | | | | | | | | | | | | | | | | up the definition, rather than the whole tokenizing system, which lost type checking. Added a new module addrmap.c which implements the address map classes, and changed the macros to call methods on the address_map and address_map_entry classes which are strongly typed. Fixed a few incorrectly specified memory map entries along the way. Please double-check to make sure the behavior is expected in: twincobr.c, lordgun.c, galaxold.c. This change also means that since the address_maps are now constructor functions, they are detected when not used, so a number of #ifdef UNUSED_CODE were added around dangling address map definitions. Also included with this change: - removed cputag_clocks_to_attotime() and cputag_attotime_to_clocks() in favor of just expanding the class - same for cputag_suspend() and cputag_resume()

* Moved debugging structure away from CPUs only and attached to all Aaron Giles2010-07-061-2/+1
| | | | | | | | | | | | | | | | 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()
* Created CPU-specific device types for all CPUs, using new macros Aaron Giles2010-07-031-66/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | DECLARE_LEGACY_CPU_DEVICE and DEFINE_LEGACY_CPU_DEVICE. Changed CPUs to be their own device types, rather than all of type CPU with a special internal subtype. Note that as part of this process I removed the CPU_ prefix from the ALL-CAPS device name, so CPU_Z80 is just plain old Z80 now. This required changing a couple of names like 8080 to I8080 so that there was an alphabetic first character. Added memory interfaces to the list of fast-access interfaces. To do this properly I had to add a separate method to devices which is called immediately after construction, when it is possible to perform dynamic_casts on fully-constructed objects. (This is just internal, no changes necessary to the devices themselves.) Some additional notes: * SH2 and SH4 had typedefs that conflicted with their CPU_-less names so I bulk renamed to structures to sh2_state and sh4_state; RB, feel free to choose alternate names if you don't like 'em * SCSP was caught doing something to the 3rd indexed CPU. Since several systems that use SCSP don't even have 3 CPUs, I had no idea what this was supposed to do, so I changed to it reference "audiocpu" assuming that stv was the assumed target. This is really gross and should be a configuration parameter, not a hard-coded assumption.

* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-0/+550
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]
