* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-66/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Switch from m_machine to machine() everywhere. In some cases this Aaron Giles2011-04-181-5/+5
| | | | | | | | | | | 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 *)

* Convert emu_timers to objects. Move implementation and management of Aaron Giles2011-02-061-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | timers into the scheduler. 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.

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]
* z80sio: Added register access functions to prevent trampoline functions ↵ Dirk Best2010-03-081-0/+52

* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

And added a casting operator to const char * for seamless use in most functions that take plain old C strings.

Removed a lot of annoying memory management code as a result. Changed interfaces that accepted/returned an astring * to use an astring & instead. Removed auto_alloc_astring(machine). Use auto_alloc(machine, astring) instead.

* Cleaned up device and sound interfaces to match the CPU Aaron Giles2008-12-191-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | interfaces when handling strings. Namely, the generic get_info functions allocate a temporary string and the device in question copies its string to the target, instead of assigning a const char *. Updated all device and sound cores to operate this way. Added the concept of a cpu_state_table, which is supplied by the CPU cores and which describes all the register state accessible to the debugger and other subsystems. The format of the table is such that most data can be simply fetched from memory without the further involvement of the CPU core, including the display of common formats. Extensibility points are available for custom display and for importing/exporting the data to intermediate variables for more complicated scenarios. Updated the ADSP21xx, TMS340x0, and i86 cores to use this. Removed the old debugger register list, which was never used. Replaced it with using ordering from the cpu_state_table. Renamed REG_PC -> REG_GENPC, REG_SP -> REG_GENSP, and REG_PREVIOUSPC -> REG_GENPCBASE. Updated a few spots that were using these directly. Moved these definitions into the end of the register area rather than leaving them outside which put them in a weird range.
* Made the concept of a "clock" native to devices. The clock is now Aaron Giles2008-12-181-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | specified when the device is added, and the clock is available in the device_config directly via device->clock. Updated all devices that have a clock to specify it when adding the device, rather than as part of their configuration. As part of this work, also created device-specific _ADD and _REMOVE macros to simplify configuration. Dfined a generic device execute function callback, though it is not used yet. The long term plan is that any device with an execute callback will be scheduled along with the CPUs. Now that CPUs are devices, their scheduling will be moved over to this logic eventually. Changed various NVRAM devices to fetch their default memory region from the device->region rather than specifying it in the configuration. Moved a number of CPUINFO_PTR_* constants to CPUINFO_FCT_*. Fixed several drivers that manually created their own gfx_elements to fill in the machine object, so they no longer crash. Fixed incorrect CPU display on info screen (recently broken). Moved device startup to *before* the DRIVER_INIT is called. This is to allow the DRIVER_INIT to configure devices that have been properly allocated. So far I don't see any negative effects, but be on the lookout if something weird shows up. Rewrote the device iteration logic to make use of the typenext field and the newly-introduced classnext field for iterating more efficiently through devices of a given type or class. Fixed behavior of MDRV_CPU_REPLACE so it does not delete and then re-add a CPU (causing the order to change).
* Here's the big one.... Aaron Giles2008-12-111-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | Added new function cpuexec_describe_context(machine) which can be used in logerror() and other printf-style functions to return a description of the current CPU/PC given only the machine. Changed several dozen sites to use this instead of directly interrogating the activecpu. Removed all other uses of activecpu throughout the system. Removed activecpu from the machine structure to prevent future abuse. Removed cpu_push_context() and cpu_pop_context(), and all call sites. Voodoo devices now require a CPU to be defined in the configuration in order to know whom to steal cycles from or stall when FIFOs get full. Updated all voodoo users to specify one. CPD1869 devices now also require a CPU to be defined in the configuration, in order to know which CPU's registers to fetch. Updated all cdp1869 users to specify one. Many other small changes to make this all work.

| | | | | | | | | | | | | | | | | | | | | | | This contains three different patches: 20080829.patch Introducing the running_machine* parameter in a few more places. Next step would be to make the execute_* function aware of it, if that's OK. Also used the machine parameter in memory.c were it's available. 20080829_1.patch The already discussed and probably being rejected removal of dreprecat.h from debugger.h. I think this is a low-risk patch (we had worse cleanups) and it lowers the risk of new code using deprecated function beign introduced in MAME/MESS, because there is no invisible inclusion of deprecat.h anymore (I think one driver - kofball.c - got it with deprecated code). 20080829_2.patch The last Machine -> machine conversion I had sitting in my local tree. I know the proper way is to turn them into devices, but I still haven't looked into that.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subject: [patch] More Machine->machine changes, add machine to irq callbacks Hi mamedev, Here are two more patches to eliminate Machine globals. The first patch was autogenerated by the attached fixup script. That script has been updated to catch additional cases which it previously missed (when Machine is the last parameter to a function or Machine is used in an assignment). This makes ~50 more files deprecat.h free. A sizable chunk (~20%) of the remaining uses of the Machine global in the drivers are due to irq callbacks for sound and machine updates. Typically such callbacks need to call cpunum_set_input_line, which requires a machine parameter, so if the callbacks don't pass the machine parameter, these routines have no choice but to reference the global variable. The second patch attempts to address most cases of this by adding the machine parameter to the callback interfaces. This allows us to remove #include "deprecat.h" from ~150 files, at the cost of having to fix up hundreds of callbacks. In total, these patches reduced the number of files with deprecat.h from 783 to 575. ~aa
* Added running_machine * parameter to the front of all read/write handlers. Aaron Giles2008-03-051-8/+9
| | | | | | | | | | | | | | | | | | Updated all call-through handlers appropriately. Renamed read8_handler to read8_machine_func, replicating this pattern throughout. Defined new set of memory handler functions which are similar but which pass a const device_config * in place of the running_machine *. These are called read8_device_func, etc. Added macros READ8_DEVICE_HANDLER() for specifying functions of this type. Note that some plumbing still needs to happen in memory.c before this will work. This check-in should remove the need for the global Machine and in turn "deprecat.h" for a lot of drivers, but that work has not been done. On the flip side, some new accesses to the global Machine were added in the emu/ files. These should be addressed over time, but are smaller in number than the references in the driver.
* Split timer_adjust() into timer_adjust_oneshot() and timer_adjust_periodic(). Aaron Giles2008-02-061-1/+1
| | | | | Updated all call sites. Fixed recent build breaks.
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
| | | | | | - removed years from copyright notices - removed redundant (c) from copyright notices - updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* (From Atari Ace) Aaron Giles2007-12-311-5/+1
| | | | | | | | The attached patch adjusts most conditional logging in MAME to use the idiom "do { if (VERBOSE) logerror x; } while (0)". This has the benefit that the compiler checks the syntax of the logging even in the case it will be eliminated, and in fact a number of cases here needed adjustments to compile because of this.
