| | | | | | | | | | | | | | | | | | | | | | | | Low-level input upgrade. Classes now exist for input_codes, input_items, input_devices, and input_seqs. Also created an input_manager class to hold machine-global state and made it accessible via machine.input(). Expanded the device index range (0-255, up from 0-16), and the OSD can now specify the device index explicitly if they can better keep the indexes from varying run-to-run. [Aaron Giles] Note that I've built and run SDL on Windows, but not all the code paths were exercised. If you use mice/joysticks extensively double-check them to be sure it all still works as expected. This is mainly an OSD and core change. The only thing impacting drivers is if they query for specific keys for debugging. The following S&Rs took care of most of that: S: input_code_pressed( *)\(( *)([^, ]+) *, * R: \3\.input\(\)\.code_pressed\1\(\2 S: input_code_pressed_once( *)\(( *)([^, ]+) *, * R: \3\.input\(\)\.code_pressed_once\1\(\2

* Changed input read/write and crosshair callbacks into delegates. Aaron Giles2011-05-111-22/+66
| | | | | Changed signature for callbacks to take an input_field_config reference instead of pointer.
* Switch input ports to use function-based constructors instead of tokens. Aaron Giles2011-05-101-210/+215
| | | | | | | | | Remove the old tokenizing helpers. Add basic classes for ports, fields, settings, and dip locations as a first step. These will be fully cleaned up later. Added machine() method to field to hide all the necessary indirection. Changed custom/changed handlers into generic read/write handlers, and added wrappers to convert them to device read/write lines. [Aaron Giles]

* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Privatized most of the m_machine pointers in the system to prevent Aaron Giles2011-04-191-1/+4

* BIG update. Aaron Giles2011-03-291-32/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 *)

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]

| | | | | | | | along with a tagmap. Changed memory regions, input ports, and devices to use this class. For devices, converted typenext and classnext fields into methods which dynamically search for the next item. Changed a number of macros to use the features of the class, removing the need for a bunch of helper functions.
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-15/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)

Removed input_port_read_handler8/16/32/64 functions, since they were really only used for getting a memory handler for a port by tag, and this is no longer necessary. Moved input port handlers to internal code in the memory system. Added port names to the taito8741 device pending its proper devicification. Removed all remaining uses of input_port_n_r() functions, and purged them from src/emu/machine/generic.
* Ok, this is The Big One. Aaron Giles2009-02-111-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
