* dimemory: Add the target address space to translate, wrap the constants Olivier Galibert2023-03-181-30/+9
| | | | divtlb: Wrap the constants
* formats, osd, util: Started refactoring file I/O stuff. (#8456) Vas Crabb2021-08-221-5/+5
| | | | | | | | | Added more modern generic I/O interfaces with implementation backed by stdio, osd_file and core_file, replacing io_generic. Also replaced core_file's build-in zlib compression with a filter. unzip.cpp, un7z.cpp: Added option to supply abstract I/O interface rather than filename. Converted osd_file, core_file, archive_file, chd_file and device_image_interface to use std::error_condition rather than their own error enums. Allow mounting TI-99 RPK from inside archives.
* Fairly significant overhaul of Lua engine and some cleanup. Vas Crabb2020-11-251-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The things that were previously called device iterators are not iterators in the C++ sense of the word. This is confusing for newcomers. These have been renamed to be device enumerators. Several Lua methods and properties that previously returned tables now return lightweight wrappers for the underlying objects. This means creating them is a lot faster, but you can't modify them, and the performance characteristics of different operations varies. The render manager's target list uses 1-based indexing to be more like idiomatic Lua. It's now possible to create a device enumerator on any device, and then get subdevices (or sibling devices) using a relative tag. Much more render/layout functionality has been exposed to Lua. Layout scripts now have access to the layout file and can directly set the state of an item with no bindings, or register callbacks to obtain state. Some things that were previously methods are now read-only properties. Layout files are no longer required to supply a "name". This was problematic because the same layout file could be loaded for multiple instances of the same device, and each instance of the layout file should use the correct inputs (and in the future outputs) for the device instance it's associated with. This should also fix video output with MSVC builds by avoiding delegates that return things that don't fit in a register.

* emumem: Simplify memory management. [O. Galibert] Olivier Galibert2020-11-021-2/+0
| | | | | | | | | | | | | | | | | | | | API impact: - install_ram/rom/writeonly now requires a non-null pointer. If you want automatically managed ram, add it to a memory map, not in machine_start - install_*_bank now requires a memory_bank *, not a string - one can create memory banks outside of memory maps with memory_bank_creator - one can create memory shares outside of memory maps with memory_share_creator Memory maps impact: - ram ranges with overlapping addresses are not shared anymore. Use .share() - ram ranges touching each other are not merged anymore. Stay in your range Extra note: - there is no need to create a bank just to dynamically map some memory/rom. Just use install_rom/ram/writeonly

* Changes to debugger memory address translation AJR2017-08-011-5/+20
| | | | | | - memory_translate now returns an address space number rather a boolean flag, permitting addresses in part of one space to map to an entirely different space. This is primarily intended to help MCUs which have blocks of internal memory that can be dynamically remapped, but may also allow for more accurate emulation of MMUs that drive multiple external address spaces, since the old limit of four address spaces per MAME device has been lifted. - memory_translate has also been made a const method, in spite of a couple of badly behaved CPU cores that can't honestly treat it as one. - The (read|write)_(byte|word|dword|qword|memory|opcode) accessors have been transferred from debugger_cpu to device_memory_interface, with somewhat modified arguments corresponding to the translate function it calls through to if requested.

* Devfind revision phase 1, cleaning out some legacy stuff AJR2016-04-071-0/+3
| | | | | | | | - Eliminate the cached device_t::m_region pointer and its region() getter method. Devices that need to bind to a region with the same tag should use optional/required_memory_region or optional/required_region_ptr with DEVICE_SELF as the subtag; this improves error checking. (DEVICE_SELF has been moved to device.h for greater visibility in the source.) - Allow required/optional_region_ptr to specify a specific length which must match that of the region found. - Implement finder_base::finder_tag() getter for diagnostic purposes. - Perform some (not very efficient) validity checks on memory region finders instead of allowing them to automatically pass. - Privatize device_memory_interface::m_addrspace.

| | | | | | | | | | | | device_memory_interface::space() assert against NULL and return a reference, and pushed references throughout all address space usage in the system. Added a has_space() method to check for those rare case when it is ambiguous.

* Add ambiguous execute() and memory() methods to the Aaron Giles2012-09-111-0/+4

* Move devices into a proper hierarchy and handle naming Aaron Giles2012-01-241-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and paths consistently for devices, I/O ports, memory regions, memory banks, and memory shares. [Aaron Giles] NOTE: there are likely regressions lurking here, mostly due to devices not being properly found. I have temporarily added more logging to -verbose to help understand what's going on. Please let me know ASAP if anything that is being actively worked on got broken. As before, the driver device is the root device and all other devices are owned by it. Previously all devices were kept in a single master list, and the hierarchy was purely logical. With this change, each device owns its own list of subdevices, and the hierarchy is explicitly manifest. This means when a device is removed, all of its subdevices are automatically removed as well. A side effect of this is that walking the device list is no longer simple. To address this, a new set of iterator classes is provided, which walks the device tree in a depth first manner. There is a general device_iterator class for walking all devices, plus templates for a device_type_iterator and a device_interface_iterator which are used to build iterators for identifying only devices of a given type or with a given interface. Typedefs for commonly-used cases (e.g., screen_device_iterator, memory_interface_iterator) are provided. Iterators can also provide counts, and can perform indexed lookups. All device name lookups are now done relative to another device. The maching_config and running_machine classes now have a root_device() method to get the root of the hierarchy. The existing machine->device("name") is now equivalent to machine->root_device().subdevice("name"). A proper and normalized device path structure is now supported. Device names that start with a colon are treated as absolute paths from the root device. Device names can also use a caret (^) to refer to the owning device. Querying the device's tag() returns the device's full path from the root. A new method basetag() returns just the final tag. The new pathing system is built on top of the device_t::subtag() method, so anyone using that will automatically support the new pathing rules. Each device has its own internal map to cache successful lookups so that subsequent lookups should be very fast. Updated every place I could find that referenced devices, memory regions, I/O ports, memory banks and memory shares to leverage subtag/subdevice (or siblingtag/siblingdevice which are built on top). Removed the device_list class, as it doesn't apply any more. Moved some of its methods into running_machine instead. Simplified the device callback system since the new pathing can describe all of the special-case devices that were previously handled manually. Changed the core output function callbacks to be delegates. Completely rewrote the validity checking mechanism. The validity checker is now a proper C++ class, and temporarily takes over the error and warning outputs. All errors and warnings are collected during a session, and then output in a consistent manner, with an explicit driver and source file listed for each one, as well as additional device and/or I/O port contexts where appropriate. Validity checkers should no longer explicitly output this information, just the error, assuming that the context is provided. Rewrote the software_list_device as a modern device, getting rid of the software_list_config abstraction and simplifying things. Changed the way FLAC compiles so that it works like other external libraries, and also compiles successfully for MSVC builds.
* Collapsed device_config and device_t into one class. Updated all Aaron Giles2011-04-271-41/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* Created new enum type address_spacenum for specifying an address Aaron Giles2011-03-271-23/+14
| | | | | | | | | | | | 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.
* Added device_t::memory() to fetch a reference to the memory interface, Aaron Giles2011-03-271-25/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | or assert if not present. Split address_space::install_[legacy_]handler into install_[legacy_]read_handler, install_[legacy_]write_handler, and install_[legacy_]readwrite_handler. Added variants of address_space handler installers which don't take mirror or mask parameters, since this is by far the most common case. Deprecated API cleanup. Simple search & replace: cpu_suspend ==> device_suspend cpu_resume ==> device_resume cpu_yield ==> device_yield cpu_spin ==> device_spin cpu_spinuntil_trigger ==> device_spin_until_trigger cpu_spinuntil_time ==> device_spin_until_time cpu_spinuntil_int ==> device_spin_until_interrupt cpu_eat_cycles ==> device_eat_cycles cpu_adjust_icount ==> device_adjust_icount cpu_triggerint ==> device_triggerint cpu_set_input_line ==> device_set_input_line cpu_set_input_line_vector ==> device_set_input_line_vector cpu_set_input_line_and_vector ==> device_set_input_line_and_vector cpu_set_irq_callback ==> device_set_irq_callback More complex changes: device_memory(device) ==> device->memory() device_get_space(device, spacenum) ==> device->memory().space(spacenum) cpu_get_address_space(cpu, spacenum) ==> cpu->memory().space(spacenum) cputag_get_address_space(mach, tag, spacenum) ==> mach->device("tag")->memory().space(spacenum) cputag_get_clock(mach, tag) ==> mach->device("tag")->unscaled_clock() cputag_set_clock(mach, tag, hz) ==> mach->device("tag")->set_unscaled_clock(hz) Some regex'es for the more prevalent cases above: S: cpu_get_address_space( *)\(( *)([^,]+)( *), * R: \3->memory().space\1\(\2 S: cputag_get_address_space( *)\(( *)([^,]+)( *),( *)([^,]+)( *), * R: \3->device\1\(\2\6\7\)->memory().space\1\(\2 S: cputag_get_clock( *)\(( *)([^,]+)( *),( *)([^ )]+) *\) R: \3->device\1\(\2\6\7\)->unscaled_clock\(\)
* Converted core_options to a class. Removed a bunch of marginal Aaron Giles2011-03-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | functionality in favor of alternate mechanisms. Errors are now reported via an astring rather than via callbacks. Every option must now specify a type (command, integer, float, string, boolean, etc). Command behavior has changed so that only one command is permitted. [Aaron Giles] Changed fileio system to accept just a raw searchpath instead of an options/option name combination. [Aaron Giles] Created emu_options class dervied from core_options which wraps core emulator options. Added mechanisms to cleanly change the system name and add/remove system-specific options, versus the old way using callbacks. Also added read accessors for all the options, to ensure consistency in how parameters are handled. Changed most core systems to access emu_options instead of core_options. Also changed machine->options() to return emu_options. [Aaron Giles] Created cli_options class derived from emu_options which adds the command-line specific options. Updated clifront code to leverage the new class and the new core behaviors. cli_execute() now accepts a cli_options object when called. [Aaron Giles] Updated both SDL and Windows to have their own options classes, derived from cli_options, which add the OSD-specific options on top of everything else. Added accessors for all the options so that queries are strongly typed and simplified. [Aaron Giles] Out of whatsnew: I've surely screwed up some stuff, though I have smoke tested a bunch of things. Let me know if you hit anything odd. Also I know this change will impact the WINUI stuff, please let me know if there are issues. All the functionality necessary should still be present. If it's not obvious, please talk to me before adding stuff to the core_options class.
* mame_file is now emu_file and is a class. It is required Aaron Giles2011-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | to pass a core_options object to the constructor, along with a search path. This required pushing either a running_machine or a core_options through some code that wasn't previously ready to handle it. emu_files can be reused over multiple open/close sessions, and a lot of core code cleaned up nicely as things were converted to them. Also created a file_enumerator class for iterating over files in a searchpath. This replaces the old mame_openpath functions. Changed machine->options() to return a reference. Removed public nvram_open() and fixed jchan/kaneko16 to stop directly saving NVRAM. Removed most of the mame_options() calls; this will soon go away entirely, so don't add any more. Added core_options to device_validity_check() so they can be used to validate things.
* MDRV_* -> MCFG_* Aaron Giles2010-12-311-7/+7
| | | | | There hasn't been a machine driver for many years.
* De-converted MACHINE_DRIVER from tokens back to constructor functions, regaining Aaron Giles2010-08-261-3/+4
| | | | | | | | | | | type safety. If legacy devices still use inline data, those types are not checked. However, new devices no longer have access to the generic m_inline_data. Instead their MDRV_* macros should map to calls to static functions in the device config class which downcast a generic device_config to the specific device config, and then set the appropriate values. This is not to be done inline in order to prevent further code bloat in the constructors. See eeprom/7474/i2cmem/okim6295 for examples. #ifdef'ed several unused machine driver definitions that weren't referenced.
* Replace "const address_space" with "address_space" throughout the system. Aaron Giles2010-08-191-1/+1
| | | | | | | | | | | The purpose of making it const before was to discourage direct tampering, but private/protected does a better job of that now anyhow, and it is annoying now. s/const[ \t]+address_space\b/address_space/g; Is basically what I did.
* Massive memory system change. This is another step along the path toward Aaron Giles2010-08-191-46/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | supporting cleaner implementations of drivers in the explicitly OO world. Expect a follow-on of several more changes to clean up from this one, which deliberately tried to avoid touching much driver code. Converted address_space to a class, and moved most members behind accessor methods, apart from space->machine and space->cpu. Removed external references to 8le/8be/16le/16be/32le/32be/64le/64be. All external access is now done via virtual functions read_byte()/read_word()/etc. Moved differentiation between the endianness and the bus width internal to memory.c, and also added a new axis to support small/large address spaces, which allows for faster lookups on spaces smaller than 18 bits. Provided methods for most global memory operations within the new address_space class. These will be bulk converted in a future update, but for now there are inline wrappers to hide this change from existing callers. Created new module delegate.h which implements C++ delegates in a form that works for MAME. Details are in the opening comment. Delegates allow member functions of certain classes to be used as callbacks, which will hopefully be the beginning of the end of fetching the driver_data field in most callbacks. All classes that host delegates must derive from bindable_object. Today, all devices and driver_data do implicitly via their base class. Defined delegates for read/write handlers. The new delegates are always passed an address_space reference, along with offset, data, and mask. Delegates can refer to methods either in the driver_data class or in a device class. To specify a callback in an address map, just use AM_READ_MEMBER(class, member). In fact, all existing AM_ macros that take read/write handlers can now accept delegates in their place. Delegates that are specified in an address map are proto-delegates which have no object; they are bound to their object when the corresponding address_space is created. Added machine->m_nonspecific_space which can be passed as the required address_space parameter to the new read/write methods in legacy situations where the space is not provided. Eventually this can go away but we will need it for a while yet. Added methods to the new address_space class to dynamically install delegates just like you can dynamically install handlers today. Delegates installed this way must be pre-bound to their object. Moved beathead's read/write handlers into members of beathead_state as an example of using the new delegates. This provides examples of both static (via an address_map) and dynamic (via install_handler calls) mapping using delegates. Added read/write member functions to okim6295_device as an example of using delegates to call devices. Updated audio/williams.c as a single example of calling the device via its member function callbacks. These will be bulk updated in a future update, and the old global callbacks removed. Changed the DIRECT_UPDATE_CALLBACKs into delegates as well. Updated all users to the new function format. Added methods on direct_read_data for configuring the parameters in a standard way to make the implementation clearer. Created a simple_list template container class for managing the common singly-linked lists we use all over in the project. Many other internal changes in memory.c, mostly involving restructuring the code into proper classes.
* Return to type safety. Changed address maps back into functions that build Aaron Giles2010-08-011-7/+7
| | | | | | | | | | | | | | | | | | | | | up the definition, rather than the whole tokenizing system, which lost type checking. Added a new module addrmap.c which implements the address map classes, and changed the macros to call methods on the address_map and address_map_entry classes which are strongly typed. Fixed a few incorrectly specified memory map entries along the way. Please double-check to make sure the behavior is expected in: twincobr.c, lordgun.c, galaxold.c. This change also means that since the address_maps are now constructor functions, they are detected when not used, so a number of #ifdef UNUSED_CODE were added around dangling address map definitions. Also included with this change: - removed cputag_clocks_to_attotime() and cputag_attotime_to_clocks() in favor of just expanding the class - same for cputag_suspend() and cputag_resume()
* C++-ified the debugger views. Not quite architecturally where I would Aaron Giles2010-06-251-32/+3
| | | | | | | | | | | like them, but it's a start. Split implementation of individual view types out to separate files. Updated all callers. Also: * fixed okim6295 memory view * changed emualloc to free resource pools from earliest to latest so that early objects can safely clean up stuff they allocated
* Cleanups and version bump. Aaron Giles2010-06-171-18/+18

* Split implementation for legacy devices into a separate macro. Updated all Aaron Giles2010-06-111-1/+1
| | | | | | | | devices to use this macro in their .c file. This greatly reduces the amount of work the linker has to do to combine all the instances, and reduces the final binary size when building with symbols. Unfortunately, in order to do it I had to switch back to macros from templates, but I can live with that for legacy devices.
* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-0/+292
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]
