* Added byuu's cothread library, along with a wrapper class. Switched to Aaron Giles2011-06-251-0/+2
| | | | | | | | | | | | using one cothread for each executable device. This functionality is strictly internal and should result in no changes in scheduling behavior. However, it now becomes possible to exit out of a device's execution in the midst of an instruction by calling machine().scheduler().make_active(). Note that this is somewhat dangerous for cores that have logic at the start of their execute loop to check for interrupts or other conditions, as those checks will be skipped upon resume, so consider this sort of early exiting to be highly experimental for now.

* Fix inverted check on anonymous timers prior to saving state. Also Aaron Giles2011-06-051-1/+6
| | | | | | | fix bug where we fail to ignore the permanent non-expiring anonymous timer. Added code to log timers, and we now log them at each save attempt as well as at restore time. Should fix most recent save state releated regressions. [Aaron Giles]

* Switch to using delegates for some callbacks: Aaron Giles2011-04-271-9/+17
| | | | | | | | | | | | - non-device timer callbacks - machine state changing callbacks - configuration callbacks - per-screen VBLANK callbacks - DRC backend callbacks For the timer case only, I added wrappers for the old-style functions. Over time, drivers should switch to device timers instead, reducing the number of timers that are directly allocated through the scheduler.
* Switch from m_machine to machine() everywhere. In some cases this Aaron Giles2011-04-181-0/+1
| | | | | | | | | | | meant adding a machine() accessor but it's worth it for consistency. This will allow future changes from reference to pointer to happen transparently for devices. [Aaron Giles] Simple S&R: m_machine( *[^ (!=;]) machine()\1
* BIG update. Aaron Giles2011-03-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 *)

* Moved the state saving system to C++. For now the registration macros Aaron Giles2011-02-081-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | are still intact. The new state_manager class has templatized methods for saving the various types, and through template specialization can save more complex system types cleanly (like bitmaps and attotimes). Added new mechanism to detect proper state save types. This is much more strict and there will likely be some games/devices that fatalerror at startup until they are remedied. Spot checking has caught the more common situations. The new state_manager is embedded directly in the running_machine, allowing objects to register state saving in their constructors now. Added NAME() macro which is a generalization of FUNC() and can be used to wrap variables that are registered when directly using the new methods as opposed to the previous macros. For example: machine->state().save_item(NAME(global_item)) Added methods in the device_t class that implicitly register state against the current device, making for a cleaner interface. Just a couple of required regexes for now: state_save_register_postload( *)\(( *)([^,;]+), * \3->state().register_postload\1\(\2 state_save_register_presave( *)\(( *)([^,;]+), * \3->state().register_presave\1\(\2

Retain TIMER devices as a separate wrapper in timer.c/.h. Inline wrappers are currently provided for all timer operations; a future update will bulk clean these up. Rather than using macros which hide generation of a string-ified name for callback functions, the new methods require passing both a function pointer plus a name string. A new macro FUNC() can be used to output both, and another macro MFUNC() can be used to output a stub-wrapped class member as a callback. Also added a time() method on the machine, so that machine->time() gives the current emulated time. A wrapper for timer_get_time is currently provided but will be bulk replaced in the future. For this update, convert all classic timer_alloc, timer_set, timer_pulse, and timer_call_after_resynch calls into method calls on the scheduler. For new device timers, added methods to the device_t class that make creating and managing these much simpler. Modern devices were updated to use these. Here are the regexes used; some manual cleanup (compiler-caught) will be needed since regex doesn't handle nested parentheses cleanly 1. Convert timer_call_after_resynch calls timer_call_after_resynch( *)\(( *)([^,;]+), *([^,;]+), *([^,;]+), *([^);]+)\) \3->scheduler().synchronize\1\(\2FUNC(\6), \5, \4\) 2.

| | | | | | | | | | | | | | | | | | | running_machine definition and implementation. Moved global machine-level operations and accessors into methods on the running_machine class. For the most part, this doesn't affect drivers except for a few occasional bits: mame_get_phase() == machine->phase() add_reset_callback() == machine->add_notifier(MACHINE_NOTIFY_RESET, ...) add_exit_callback() == machine->add_notifier(MACHINE_NOTIFY_EXIT, ...) mame_get_base_datetime() == machine->base_datetime() mame_get_current_datetime() == machine->current_datetime() Cleaned up the region_info class, removing most global region accessors except for memory_region() and memory_region_length(). Again, this doesn't generally affect drivers.

* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-0/+104
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]
