* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-386/+399
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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]
* Made device->tag and devconfig->tag into private member variables (m_tag). Aaron Giles2010-03-081-2/+8
| | | | | | Added inline tag() function to return a const char * version. Updated callers to use this instead of directly accessing tag.cstr() which was awkward.

* Remove some aliases between CPUINFO_ and DEVINFO_ to help clarify Aaron Giles2010-01-211-3/+2
| | | | | | usage. Also converted a few more places to use the new accessors.
* Made direct accessors for device configuration state. Currently they Aaron Giles2010-01-211-20/+40

* Mark these virtual before I forget and later waste time debugging it. Aaron Giles2010-01-201-2/+2
|
* Convrted the rest of devintrf to classes and moved management Aaron Giles2010-01-191-168/+142
| | | | | | functions into methods of those classes. The most wide-ranging change was converting device_reset() to device->reset(). Apart from that it was mostly internal shuffling in the core.
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-135/+209
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* device_find_child_by_tag() -> device->subdevice() Aaron Giles2010-01-171-7/+0
|
* Created new template class tagged_list which manages a simple list Aaron Giles2010-01-171-73/+45
| | | | | | | | 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.
* Cleanups and version bump. Aaron Giles2010-01-161-3/+3
|
* Added casting operators to the region_info class so you can assign Aaron Giles2010-01-161-3/+14
| | | | | | | | | | | | | | | | a region to a generic type pointer and have it automatically convert. Also added a bytes() method which is safe if the region is NULL (useful for saying machine->region("foo")->bytes() and not crashing if foo doesn't exist). Changed the region field in the device_config to be a region_info *, and removed the regionbytes field. Updated all users of these fields to use the new casting operators and bytes() methods instead. Added subdevice and subregion methods to the device_config class, so you can easily query for devices and regions that are device-specific. The device prefix ("devicename:") is automatically prepended.
* Within src/emu, basic conversions: Aaron Giles2010-01-121-7/+7
| | | | | | devtag_get_device ... machine->device() memory_find_address_space ... device->space()
* Fixed memory freeing so that is it released in the opposite order Aaron Giles2010-01-111-2/+28
| | | | | | | | | | | | | | | | it was originally allocated. Changed machine->region() to return a pointer to the now-public region_info class. Added new member function space() to the device_config, along with shorter constants to be used (AS_PROGRAM, AS_DATA, AS_IO). With no parameters, space() returns the first address space, which is commonly the only space present. Updated a few devices that referenced the old space[] array to call the new function instead. Added #define to emualloc to ensure delete can't be freely used.
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-24/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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!)
* Extended the astring class wrapper into something useful, and Aaron Giles2010-01-081-2/+2
| | | | | | | | | | | | | | | | | | useable as a stack object. Also designed the interfaces to allow for chaining operations. And added a casting operator to const char * for seamless use in most functions that take plain old C strings. Changed all uses of astring to use the object directly on the stack or embedded in objects instead of explicitly allocating and deallocating it. 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.
* NOTE: This change requires two new osd functions: osd_malloc() and Aaron Giles2010-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | osd_free(). They take the same parameters as malloc() and free(). Renamed mamecore.h -> emucore.h. New C++-aware memory manager, implemented in emualloc.*. This is a simple manager that allows you to add any type of object to a resource pool. Most commonly, allocated objects are added, and so a set of allocation macros is provided to allow you to manage objects in a particular pool: pool_alloc(p, t) = allocate object of type 't' and add to pool 'p' pool_alloc_clear(p, t) = same as above, but clear the memory first pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type 't' and add to pool 'p' pool_alloc_array_clear(p, t, c) = same, but with clearing pool_free(p, v) = free object 'v' and remove it from the pool Note that pool_alloc[_clear] is roughly equivalent to "new t" and pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also note that pool_free works for single objects and arrays. There is a single global_resource_pool defined which should be used for any global allocations. It has equivalent macros to the pool_* macros above that automatically target the global pool. In addition, the memory module defines global new/delete overrides that access file and line number parameters so that allocations can be tracked. Currently this tracking is only done if MAME_DEBUG is enabled. In debug builds, any unfreed memory will be printed at the end of the session. emualloc.h also has #defines to disable malloc/free/realloc/calloc. Since emualloc.h is included by emucore.h, this means pretty much all code within the emulator is forced to use the new allocators. Although straight new/delete do work, their use is discouraged, as any allocations made with them will not be tracked. Changed the familar auto_alloc_* macros to map to the resource pool model described above. The running_machine is now a class and contains a resource pool which is automatically destructed upon deletion. If you are a driver writer, all your allocations should be done with auto_alloc_*. Changed all drivers and files in the core using malloc/realloc or the old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros instead, or the global_alloc_* macros if necessary. Added simple C++ wrappers for astring and bitmap_t, as these need proper constructors/destructors to be used for auto_alloc_astring and auto_alloc_bitmap. Removed references to the winalloc prefix file. Most of its functionality has moved into the core, save for the guard page allocations, which are now implemented in osd_alloc and osd_free.

| | | | | | Updated device and input port lists to use the tagmap for tag searches. Also removed the whole "quark" thing from the validity checker in favor of using the tagmaps.

* Expanded address maps from 3 to 4. Moved ADDRESS_SPACE_PROGRAM/DATA/IO Aaron Giles2009-07-091-15/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | constants to cpuintrf, as those names are really only applicable to CPUs. Added new ADDRESS_MAP_0/1/2/3 constants to identify address maps more generically. Updated memory system to be more general about address map handling. Added the concept of default address maps (in addition to the already existing internal memory maps). The difference between internal and default memory maps is that internal memory maps always override everything (including user-specified maps), but default memory maps simply provide a default that can be overridden. Converted the okim6295 sound driver to use address maps for access. By default, it defines a ROM address map that overlays its full region. As a result, the validity checks require all okim6295 regions to be at least 256k, unless you provide your own address map. Updated all regions to meet this requirement. Updated the atarijsa code to use a custom address space for its okim6295 accesses (which are banked on the first half and static on the second half), as an example of configuring a device with a custom address space. For now, attempts to use okim6295_set_bank_base() will still work, though banking for the okim chips should be moved to custom address maps in the drivers eventually. The first time okim6295_set_bank_base() is called, it will install a banked memory handler over the region and use memory_set_bankptr() to change the base on subsequent bank switches. Moved address map validity checks to be run for each device instead of just each CPU.
* Another step. Moved the address-space related get_info constants Aaron Giles2009-07-081-0/+25
| | | | | | to devintrf (including endianness). Removed space array from the CPU class header. Made the memory system much more device-neutral. Various other cleanups along the way.
* Move address_map array from cpu_config to device_config. Added Aaron Giles2009-07-081-1/+2
| | | | | | | | MDRV macros in the device for specifying address maps. Changed the memory system to fetch the maps from the new location. This is just a small step toward the end goal of getting address maps into arbitrary devices.
* Added the concept of device contracts. A contract is a well-defined Aaron Giles2009-06-081-2/+26
| | | | | | | | | | | | | | | | | set of interfaces supported by a device, and identified by a unique string identifier. A device may support any number of contracts, described in a list via the DEVICE_CONTRACT_LIST* macros. The purpose of contracts is to provide a means for devices to expose a standard set of interfaces to other parts of the system. For example, the PCI device should expose a contract that includes functions for configuration register access, and 32-bit I/O. Then any device with a PCI interface should implement the PCI contract, so that the PCI bus device can route things appropriately. (This change is in anticipation of a proper Namco 06xx interface, which exposes a contract to all devices it is attached to, but I am still struggling to get it to work reliably.)
* Fixing NVRAM function name to be the same for devices/non-devices. This ↵ Fabio Priuli2009-06-031-1/+1
| | | | makes DT_HAS_NVRAM in devtempl.h work as expected.
* Converted the Namco 50xx into a proper device. Aaron Giles2009-05-261-0/+3
| | | | | | | | | | | | Extended the Namco 60xx and namcoio_init() interfaces to accept a device name string in addition to an interface struct, until all the interfaces are replaced with devices. Added DERIVED_CLOCK() macro which can be used by sub-devices to derive their clock from the parent device. Tweaked some of the laserdisc interfaces to use ROM_NAME() and MACHINE_DRIVER_NAME() macros.
* Deprecated device_set_info. Almost all devices had a NULL or empty Aaron Giles2009-04-231-26/+1
| | | | | | | | | function here. Remaining devices have been converted to have device-specific functions to do the same thing with proper type checking. CPUs still have a set_info function but it is CPU-specific now and no longer piggybacks on the general device function.
* Removed device types from device queries that use tags, under the Aaron Giles2009-03-021-20/+17
| | | | | | | | | | | | | | | assumption that all device tags are unique. Specifically, the following no longer need to provide a device type: AM_DEVREAD/WRITE DEVCB_DEVICE_HANDLER devtag_get_device devtag_reset device_list_find_by_tag as well as several device interfaces that referenced other devices. Also fixed assertion due to overflow in the recent sound fix.
* Modified the makefile to support experimental optional C++ Aaron Giles2009-02-281-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | compilation: - new option CPP_COMPILE to trigger this (off by default) - split CFLAGS into common, C-only, and C++-only flags - when enabled, CPP_COMPILE causes 'pp' to be appended to the target name NOTE THAT THE SYSTEM CANNOT ACTUALLY BE COMPILED THIS WAY YET. IT IS JUST AN EXPERIMENT. Modified lib.mak to always build zlib/expat as C regardless of CPP_COMPILE. Modified windows.mak to fix warnings with MAXOPT=1, and to leverage the new CFLAGs definitions. Modified vconv.c to do appropriate conversions for new C++ options. Updated sources so that libutil, libocore (Windows), and libosd (Windows) can be cleanly compiled as C or C++. This was mostly adding some casts against void *. Fixed a few more general obvious problems at random locations in the source: - device->class is now device->devclass - TYPES_COMPATIBLE uses typeid() when compiled for C++ - some functions with reserved names ('xor' in particular) were renamed - nested enums and structs were pulled out into separate definitions (under C++ these would need to be scoped to be referenced) - TOKEN_VALUE cannot use .field=x initialization in C++ :(
* Added the ability for devices to have their own custom inline config management. Aaron Giles2009-02-161-0/+7
| | | | | | | | | | | | This was primarily added to allow for sound routes to be supported in a way that is compatible with the current driver structure. A device can now define a DEVICE_CUSTOM_CONFIG callback which is called whenever one of the MCONFIG_TOKEN_DEVICE_CONFIG_CUSTOM_* tokens is encountered. A special token MCONFIG_TOKEN_DEVICE_CONFIG_CUSTOM_FREE is defined to clean up memory allocated and/or reset the custom configuration, and is called when the device is torn down to allow for memory cleanup. Reimplemented the sound routing using this new mechanism.
* Ok, this is The Big One. Aaron Giles2009-02-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Cleaned up device and sound interfaces to match the CPU Aaron Giles2008-12-191-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Giles2008-12-181-2/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).
* Added the concept of device "owner", for devices owned by other devices. Aaron Giles2008-12-171-2/+5
| | | | | | Modified laserdisc players to walk back to their global device state via the owner, rather than brute-force searching for the first instance and hoping that is the right one.
* Made CPUs into proper devices. CPUs are now added in the Aaron Giles2008-12-161-45/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | machine configuration just as any other device, and the standard CPU configuration is performed via the inline configuration macros. Change cpu_type from an enumeration into a pointer to the CPU's get_info function, very similar to device behavior. For now all CPUs are declared in cpuintrf.h, but eventually they should be declared in the CPU's header file, and the driver should #include that header. Added function cpu_get_type() to return the CPU type. Changed several cpu_* functions into macros that call through to the equivalent device_* function. The device system now maintains a parallel list of devices based on type, for faster iteration through all devices of a given type. Cleaned up code that looped over CPUs via the machine->cpu array to now loop using the type-based device list. Removed start/stop/reset/nvram functions from the device_config in favor of grabbing them as needed. Cleaned up the generic interrupt_enable code to work with CPU devices instead of numbers. Mapped the devtag_* functions to device_* functions via macros instead of parallel implementations.
* Changed save state system to accept machine parameters where Aaron Giles2008-12-051-5/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | appropriate, and to keep all global variables hanging off the machine structure. Once again, this means all state registration call sites have been touched: - state_save_register_global* now takes a machine parameter - state_save_register_item* now takes a machine parameter - added new state_save_register_device_item* which now uses the device name and tag to generate the base name Extended the fake sound devices to have more populated fields. Modified sound cores to use tags from the devices and simplified the start function. Renumbered CPU and sound get/set info constants to align with the device constants, and shared values where they were perfectly aligned. Set the type field in the fake device_configs for CPU and sound chips to a get_info stub which calls through to the CPU and sound specific get_info functions. This means the device_get_info() functions work for CPU and sound cores, even in their fake state. Changed device information getters from device_info() to device_get_info() to match the CPU and sound macros.
* Major cpuintrf changes: Aaron Giles2008-11-101-0/+1
| | | | | | | | | | | | | | | | | | | | | | * added a set of cpu_* calls which accept a CPU device object; these are now the preferred means of manipulating a CPU * removed the cpunum_* calls; added an array of cpu[] to the running_machine object; converted all existing cpunum_* calls to cpu_* calls, pulling the CPU device object from the new array in the running_machine * removed the activecpu_* calls; added an activecpu member to the running_machine object; converted all existing activecpu_* calls to cpu_* calls, pulling the active CPU device object from the running_machine * changed cpuintrf_push_context() to cpu_push_context(), taking a CPU object pointer; changed cpuintrf_pop_context() to cpu_pop_context(); eventually these will go away * many other similar changes moving toward a model where all CPU references are done by the CPU object and not by index
* Added new functions for building device-relative tags. Changed machine Aaron Giles2008-10-031-0/+6
| | | | | | | | | configuration builder to use these functions. Also changed the laserdisc player devices to use them. Updated Z80 CTC/SIO code to assume that the CPU provided for the clock is relative to the device that the CTC/SIO belong to. Updated memory code to assume that regions and devices referenced by the memory map are relative to the device the associated CPU belongs to.
* Changed DEVICE_START functions to return an error code. Currently this Aaron Giles2008-09-091-3/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is either DEVICE_START_OK or DEVICE_START_MISSING_DEPENDENCY. The latter should be returned by a device if there is another device it depends on which hasn't been started yet. Added new flag in the device interface to indicate whether a device has been started. Changed laserdisc interface to explicitly specify the screen and sound devices it should route to. Drivers no longer have to manually call laserdisc_vsync(). Instead, the laserdisc code connects up to the routed screen device and works based on that screen's VBLANK timing. Removed all existing calls to laserdisc_vsync(). Changed laserdisc behavior so that it completes the previous video read and initiates the next read at the end of VBLANK instead of the beginning. This gives player logic time during VBLANK to alter the slider position prior to fetching the next frame. Added new laserdisc callback for vsync begin and changed the update callback to be called at the end of VBLANK. Also added functions to set the slider speed, advance the slider, and directly control the video/ audio squelch. In addition, there is a new status function to get the slider position in general terms. Added parameter to the VBLANK callbacks supported in emu/video.c. Updated all callers to provide a callback value. Fixed bug that would cause watchpoints to trigger if you had a memory window open to the watchpoint address. Further updates to the PR-8210 ROM simulation. Still not quite there but the system is much better understood now. Added layout to the PR-8210 which displays the state of the front-panel LEDs.
* Added new device interface selector: DEVINFO_PTR_ROM_REGION. This allows a Aaron Giles2008-09-061-0/+2
| | | | | | | | | | | | | | | | | | | | | | device to provide a set of ROM regions to be loaded along with the game ROMs. It is expected that most regions defined for devices will use the ROMREGION_LOADBYNAME flag to enable the ROMs to live in a central location. Added new device interface selector: DEVINFO_PTR_MACHINE_CONFIG. This allows a device to specify a partial machine driver which is appended to the end of the machine driver for any game using that device. The intention for this is to allow devices which have their own BIOS logic to specify CPUs and other characteristics common to all systems using the device. Added new ROMREGION flag: ROMREGION_LOADBYNAME, which means that if the ROMs in that region are not found in the usual driver files, then the name of the region will be used as a driver filename for loading. Extended the ldcore interface structure to allow each player type to provide its own ROM region and partial machine driver. Moved preliminary PR-8210 emulation code from ldplayer.c to ldpr8210.c. It is currently disabled behind the EMULATE_PR8210_ROM compile time flag.

Mapped primal rage 2 inputs Mapped player 3 & 4 inputs for 1 on 1 government, these are now the default with the 6 button inputs only mapped for games that need them. Converted AT28C16 to a device. Added preliminary support for devices to load/save nvram.
