| | | | | | | | | | | | space by index. Update functions and methods that accepted an address space index to take an address_spacenum instead. Note that this means you can't use a raw integer in ADDRESS_SPACE macros, so instead of 0 use the enumerated AS_0. Standardized the project on the shortened constants AS_* over the older ADDRESS_SPACE_*. Removed the latter to prevent confusion. Also centralized the location of these definitions to memory.h.

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]
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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!)

* MIPS3 TLB fixes: Aaron Giles2009-11-171-2/+6
| | | | | | | | - fixed bug in vtlb code that caused us to lose track of previously registered fixed page ranges - fixed MIPS3 behavior that would not clear out invalid page ranges from the VTLB under certain circumstances - added support for TLB sizes less than 48 entries

| | | | | The 4300 was used on the N64 and Aleck64, and the 4310 on the IT Eagle boards. COP0 is slightly non-standard on these chips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | related APIs now take a device pointer instead of an index. All functions that take a CPU device are prefixed with cpu_* All functions that are globally related to cpu execution are prefixed with cpuexec_*. Below is a list of some of the mappings: cpu_boost_interleave -> cpuexec_boost_interleave cpunum_suspend -> cpu_suspend cpunum_resume -> cpu_resume cpunum_is_suspended -> cpu_is_suspended cpunum_get_clock -> cpu_get_clock cpunum_set_clock -> cpu_set_clock cpunum_get_clockscale -> cpu_get_clockscale cpunum_set_clockscale -> cpu_set_clockscale cpunum_get_localtime -> cpu_get_local_time cpunum_gettotalcycles -> cpu_get_total_cycles activecpu_eat_cycles -> cpu_eat_cycles activecpu_adjust_icount -> cpu_adjust_icount cpu_trigger -> cpuexec_trigger cpu_triggertime -> cpuexec_triggertime cpunum_set_input_line -> cpu_set_input_line cpunum_set_irq_callback -> cpu_set_irq_callback In addition, a number of functions retain the same name but now require a specific CPU parameter to be passed in: cpu_yield cpu_spin cpu_spinuntil_time cpu_spinuntil_int cpu_spinuntil_trigger cpu_triggerint Merged cpuint.c into cpuexec.c. One side-effect of this change is that driver reset callbacks are called AFTER the CPUs and devices are reset. This means that if you make changes to the CPU state and expect the reset vectors to recognize the changes in your reset routine, you will need to manually reset the CPU after making the change (since it has already been reset). Added a number of inline helper functions to cpuintrf.h for managing addresses Removed cpu_gettotalcpu(). This information is rarely needed outside of the core and can be obtained by looking at the machine->cpu[] array. Changed CPU interrupt acknowledge callbacks to pass a CPU device instead of machine/cpunum pair. Changed VBLANK and periodic timer callbacks to pass a CPU device instead of machine/cpunum pair. Renamed all information getters from cpu_* to cpu_get_* and from cputype_* to cputype_get_*.
* Populated tag and static_config parts of fake CPU device. Removed 'config' Aaron Giles2008-11-091-1/+1
| | | | | parameter from CPU_INIT. Modified CPU cores to pull config from the device static_config.
* WARNING: This is a significant change. If you are risk-averse and Aaron Giles2008-11-061-2/+3
| | | | | | | | | | | | | | | | | | | | | working on something, hold off syncing. Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT, CPU_EXECUTE, along with macros for the name and for calling, in the spirit of the devintrf.h macros. More will come later. Changed init, reset, exit, and execute interfaces to be passed a const device_config * object. This is a fake object for the moment, but encapsulates the machine pointer and token. Eventually this will be a real device. Changed the CPU IRQ callbacks to a proper type, and added a device parameter to them. Updated all CPU cores to the new macros and parameters. Note that this changes the way we "pointer"-ify cores. I'll send an update shortly.
* Here's another MAME tidy patch. This one adds missing const/statics, Aaron Giles2008-11-021-2/+0
| | | | | | | | | | adds/removes entries in header files, and fixes a few potential multisession issues by explicitly adding initializers. asic65.c has significant changes to accomodate using a struct instead of 16 variables, otherwise the changes in this patch are modest and obvious. [Atari Ace]

* Removed DEBUGGER flag from makefile and ENABLE_DEBUGGER Aaron Giles2008-06-261-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | macro from the source code. All MAME builds now include the debugger, and it is enabled/disabled exclusively by the runtime command-line/ini settings. This is a minor speed hit for now, but will be further optimized going forward. Changed the 'd' suffix in the makefile to apply to DEBUG builds (versus DEBUGGER builds as it did before). Changed machine->debug_mode to machine->debug_flags. These flags now indicate several things, such as whether debugging is enabled, whether CPU cores should call the debugger on each instruction, and whether there are live watchpoints on each address space. Redesigned a significant portion of debugcpu.c around the concept of maintaining these flags globally and a similar, more complete set of flags internally for each CPU. All previous functionality should work as designed but should be more robust and faster to work with. Added new debugger hooks for starting/stopping CPU execution. This allows the debugger to decide whether or not a given CPU needs to call the debugger on each instruction during the coming timeslice. Added new debugger hook for reporting exceptions. Proper exception breakpoints are not yet implemented. Added new module debugger.c which is where global debugger functions live.
* Created common virtual TLB managment module. Aaron Giles2008-06-161-4/+7

* MIPS3 recompiler: Aaron Giles2008-06-131-3/+1
| | | | | | * added UML comments for common state variables * removed some unused fields * implemented LL/LLD/SC/SCD (only works single-processor for now)

* Moved implementation-specific state into a pointer hanging off of the core Aaron Giles2008-05-291-0/+7
| | | | | | | MIPS3 state. Removed large context in favor of a pointer to the large context to help improve context switch times.
* Several miscellaneous changes: Aaron Giles2008-05-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | 1. In the MIPS core: - renamed struct mips3_config -> mips3_config - updated all drivers to the new names - removed MIPS3DRC_STRICT_COP0 flag, which is no longer used - a few minor cleanups 2. In the CPU interface: - added new 'intention' parameter to the translate callback to indicate read/write/fetch access, user/supervisor mode, and a flag for debugging - updated all call sites to pass an appropriate value - updated all CPU cores to the new prototype 3. In the UML: - added new opcode SETC to set the carry flag from a source bit - added new opcode BSWAP to swap bytes within a value - updated C, x86, x64 back-ends to support the new opcodes - updated disassembler to support the new opcodes 4. In the DRC frontend: - fixed bug in handling edge case with the PC near the 0 or ~0
* Added new front-end flag to tag privileged instructions. Aaron Giles2008-05-251-21/+3
| | | | Minor tweaks/cleanups to the MIPS3 drc.
* Numerous MIPS3 DRC updates: Aaron Giles2008-05-191-61/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Fixed front-end so that virtual no-op instructions are still targeted as branch targets. * Fixed front-end to mark the beginning of each sequence as needing TLB validation, since any sequence can be jumped to from anywhere. * Redid the MIPS3 TLB implementation. Fixed the exception vector and type handling. Changed the bitfields to directly map from the MIPS TLB format. Added distinction between TLB fill and TLB valid/modified exceptions. * Added separate modes for user, supervisor, and kernel modes. Each mode does proper verification of addresses now and generates address errors for invalid accesses. * Fixed several bugs in the TLB implementation; not everything works yet but it's a lot closer. * Made COP0 access checking mandatory in non-kernel modes. * Fixed several crashes when recompiling virtual no-ops. * Fixed TLB bug where entries for virtual address 0 were present by default. * Fixed bug in the map variable implementation that would sometimes result in incorrectly recovered values.
* Rewrote core memory handlers as inline functions. These should be easier to Aaron Giles2008-04-091-0/+1
| | | | | | | | | | | | | | | | trace through in a debug build, yet should operate the same as before. Created a complete set of functions for all databus sizes (8,16,32,64) and all endiannesses. A few functions are redundant, but it is now very clear which functions to use in which scenarios. It is also now possible to rely on being able to access values of 8, 16, 32 or 64 bits via the built-in accessors without fear of crashing. Updated all cores using 8-bit handlers to explicitly call the 8-bit handlers with the appropriate endianness. Fixed a few games which were calling n-bit handlers directly to use the generic forms. In the future, this is all the access drivers will have.
* WIP check-in. Things work now, but I'm still working on the code. Aaron Giles2008-03-091-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | Converted address maps to tokens. Changed the address_map structure to house global map-wide information and hung a list of entries off of it corresponding to each address range. Introduced new functions address_map_alloc() and address_map_free() to build/destroy these structures. Updated all code as necessary. Fixed several instances of porttagtohandler*() in the address maps. Drivers should use AM_READ_PORT() macros instead. ADDRESS_MAP_EXTERN() now is required to specify the number of databits, just like ADDRESS_MAP_START. Removed ADDRESS_MAP_FLAGS() grossness. There are now three new macros which replace its former usage. ADDRESS_MAP_GLOBAL_MASK(mask) specifies a global address-space-wide mask on all addresses. Useful for cases where one or more address lines simply are not used at all. And ADDRESS_MAP_UNMAP_LOW/HIGH specifies the behavior of unmapped reads (do they come back as 0 or ~0). Changed internal memory mapping behavior to keep only a single address map and store the byte-adjusted values next in the address map entries rather than maintaining two separate maps. Many other small internal changes/cleanups.
* Changed debugger-related code to be based off a new makefile define ↵ Aaron Giles2008-02-021-1/+1
| | | | | | | | | | | | | (DEBUGGER) which sets a new compile-time define (ENABLE_DEBUGGER). This means that MAME_DEBUG no longer means "enable debugger", it simply enables debugging features such as assertions and debug code in drivers. Also removed the various levels of opbase protection in memory.h and always just turned on full bounds checking. Fixed build break due to missing ampoker.lay -> ampoker2.lay renaming.
