* Redoing offs_t to 64-bits expansion. MooglyGuy2026-05-011-8/+0

* emu/debug: Use "classic" locale for debug console. Vas Crabb2026-01-271-5/+7
|
* lisa: Massive updates Olivier Galibert2026-01-071-19/+23
| | | | | | | | core: Better support for external mmus Note: I didn't expect to push that one right now, it's missing documentation among other things, but since some people seems to be interested to work on that driver I don't want to hold them.
* Clean up some stuff: Vas Crabb2025-09-031-8/+8
| | | | | * emu/debug/express.cpp: Reduced unnecessary duplication. * misc/crystal.cpp: Tidied a little.
* emu/debug: Extended memory commands for region and space (#13767) holub2025-08-301-1/+64

* Various optimisations to code generaton. Vas Crabb2023-03-261-4/+4
| | | | | | | | | | | | | | | util/bitmap.cpp, util/palette.cpp: Marked lots of things constexpr. Bitmaps don't throw exceptions on allocation failure, they just become invalid. Almost nothing in MAME actually checks for this. emu/profiler.cpp: Abort if the profile stack overflows rather than throwing an exception. This is a developer feature and if it overflows, the code is broken. Calling a noreturn noexcept function generates less code than throwing an exception, which adds up. util/strformat.cpp: Traded away some unnecessary flexibility for more compact code. The stream objects must derive from std::basic_ostream now - they can't just be any old objects with the expected operators.
* Various input and OSD refactoring: Vas Crabb2023-01-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | osd: Supply OSD object to modules on initialisation. Encapsulated some event handling in the OSD objects rather than leaving it in free functions. Put various stuff in namespaces. osd/modules/input: Enabled dinput, xinput and winhybrid modules for Windows SDL builds, and enabled background input for dinput and xinput (and by extension winhybrid) modules. Also fixed some COM and X11 resource leaks. osd/modules/input/input_sdl.cpp: Flipped SDL mouse button order to match Windows, and exposed vertical and horizontal scroll as Z and rZ axes. Moved SDL UI event handling out of input devices into OSD object. osd/modules/input_rawinput.cpp: Changed lightgun Z axis token so it's correctly identified as a relative axis (it maps to the scroll wheel equivalent). osd: Added an option to choose the network provider module. Mostly useful if you build with both TUN/TAP and pcap support included, or if you want to disable emulated networking completely. emu/input.cpp: Use a better strategy for assembling input code names that uses fewer temporary strings and doesn't require use of the non-Unicode-aware space trimming function (fixes MT08552). osd/modules/input_dinput.cpp: Improved polling logic. osd: Made various parts of the input code less dependent on concrete emu objects, and reduced inappropriately passing around the machine object. Made input modules less dependent on OSD implementation. Encapsulated some stuff and got rid of some vestigial newui and SDL1 support code. Cleaned up some interfaces. Moved OSD options classes to their own files. Prepare to remove main.h from emu.h - it's mostly used to get the application name, which the vast majority of emulated devices don't need to do.

* debugger: Extended target address syntax to include device/address space. ↵ Vas Crabb2021-10-011-42/+54
| | | | | | | | | | | | | | | | | | | (#8630) Added a validity check to ensure address space names are tag-like and unique, since they're now used as identifiers in debugger commands. Extended the syntax for target addresses to allow them to be qualified with a colon followed by an optional device tag and/or address space name. If only the device needs to be specified, a debugger CPU number may also be used. This makes commands like bpset and wpset more flexible, as they can operate on CPUs other than the currently visible CPU. Commands like find, fill, dump and load are more flexible as they can access any space of any device. Removed now-redundant CPU parameters from many commands, and renamed pcatmemp to pcatmem for consistency with other commands. Extended region syntax for saver/loadr to support tags relative to the visible CPU (e.g. you can use "." for the region with the same name as the visible CPU, or "^sibling" syntax). Added an optional root device parameter to memdump. Changed interpretation of Boolean values to support numeric expressions as well as true/false strings and literal 1/0. Added checks that the specified device is CPU-like to various commands that require a CPU (e.g. focus). Previously these commands would crash or trigger an assertion failure if a tag for a non-CPU devices was specified. Fixed the cpunum symbol so it uses the same rules for determining what is or isn't a CPU as parameter parsing. Made device_t sanitise subtags better. Previously you could cause an assertion failure or crash MAME by giving it unexpected relative tags via Lua or the debugger. Added help topic alias support, and reworked the data structures to improve the performance of looking up debugger commands and help topics. Removed the "ref" parameter from debugger command functions (std::bind can hold extra argument values for you if you need them). Also added an error message if duplicate debugger commands are registered. Updated help for commands that changed syntax, and also updated summaries for some commands that had changed in the past without corresponding help updates.
* Stop converting debugger console commands to all lowercase before parsing ↵ AJR2021-02-131-8/+8
| | | | | | | them. Case insensitivity has been preserved for command names, CPU and region tags and certain symbolic parameters (as well as expressions, which were treated as case-insensitive in other contexts), but filenames and character constants are no longer automatically lowercased. * debugcmd.cpp, debugcon.cpp: Remove some superfluous c_str() calls * debugcmd.cpp: Remove local member referencing debugger_cpu, which is accessed only rarely since the console now tracks the visible CPU
* Much more core std::string_view modernization AJR2021-01-201-1/+2
| | | | | | | | | | | | | | | - Remove corestr.h from emu.h; update a few source files to not use it at all - Change strtrimspace, strtrimrightspace and core_filename_extract_* to be pure functions taking a std::string_view by value and returning the same type - Change strmakeupper and strmakelower to be pure functions taking a std::string_view and constructing a std::string - Remove the string-modifying version of zippath_parent - Change tag-based lookup functions in device_t to take std::string_view instead of const std::string & or const char * - Remove the subdevice tag cache from device_t (since device finders are now recommended) and replace it with a map covering directly owned subdevices only - Move the working directory setup method out of device_image_interface (only the UI seems to actually use the full version of this) - Change output_manager to use std::string_view for output name arguments - Change core_options to accept std::string_view for most name and value arguments (return values are still C strings for now) - Change miscellaneous other functions to accept std::string_view arguments - Remove a few string accessor macros from romload.h - Remove many unnecessary c_str() calls from logging/error messages

* Fairly significant overhaul of Lua engine and some cleanup. Vas Crabb2020-11-251-2/+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.

* Debugger: add `condump` command to export console buffer to a log file (#6781) Stevie-O2020-06-071-0/+37
| | | | | | | | This is another debugger enhancement -- it allows you to export the current contents of the debug console window to a file. The filename parsing is based on the `trace` command, and as such, supports both the "{game}" placeholder, and the ">>" prefix for appending instead of overwriting.

|\ | | | | Debugger - add `-debuglog` option to log debug console output to file
| * Debugger - add `-debuglog` option to log debug console output to file Stephen Oberholtzer2020-05-071-4/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this option is specified, all console output is echoed to a log file. Some caveats/limitations: - The file-open process was copied from -log, so it has the same limits - Filename is hard-coded (debug.log) - File is overwritten if it exists - File is opened during emulation initialization - Thus, the file is cleared if you invoke the "Hard Reset" debugger command - Probably some other details I don't know about - Logging works as such: When a string is appended to the scrollback buffer, it is also written to the log file. Some commands forcibly wrap their output (e.g. `help` to 80 columns.) Because this wrapping is done inside the scrollback buffer, the text written to the file is not wrapped. This can be seen with `help execution`.
* | Debugger expression and memory access overhaul AJR2020-05-251-1/+25
|/ | | | | | | | | | | | | - Memory references in expressions no longer default to the console's visible CPU if no device name was specified, except when entered through the console itself. Expressions in view windows now use the context of the currently selected device instead. - The pcatmem debug command and similar qt mouseover function now produce an error message if the initial address translation fails. Related internal changes (nw) - The debugger_cpu class no longer interprets memory accesses. The existing routines have been moved into symbol_table (which used to invoke them as callbacks), and reimplemented in most other places. Thecode duplication is a bit messy, but could be potentially improved in the future with new utility classes. - The cheat engine no longer needs to hook into the debugger_cpu class or instantiate a dummy instance of it. - The inclusion of debug/express.h within emu.h has been undone. Some debugging structures now need unique_ptr to wrap the resulting incomplete classes; hopefully the performance impact of this is negligible. Another direct consequence is that the breakpoint, watchpoint and registerpoint classes are no longer inside device_debug and have their own source file. - The breakpoint list is now a std::multimap, using the addresses as keys to hopefully expedite lookup. - The visible CPU pointer has been removed from the debugger_cpu class, being now considered a property of the console instead. - Many minor bits of code have been simplified.

* device_state_interface: Polymorphism and std::function for entries (nw) (#2690) ajrhacker2017-10-121-3/+5
| | | | | | | | | | | * device_state_interface: Polymorphism and std::function for entries (nw) - Create a templated subclass of device_state_entry to provide separate read/write interfaces for registers of varying widths. The efficiency impact of this should be minimal, given that this eliminates the need to make each byte width a subcase for reads and writes. - Create similarly templated "pseudo-register" versions of device_state_entry that provides custom read/write interfaces through std::function. The intent of this is to eventually replace the dummy register + state_export interface hitherto necessary to provide debugger access to bankswitched or computed state registers. - State registers can now be made read-only, and this is automatically done now when state_add is called with a std::function read handler but no write handler. This property is honored by MAME debug expressions. * Add override keyword (nw) * Remove explicit instantiations that were causing linking errors in tools build (nw)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | significant change, so please pay attention. The core changes are: * Short name, full name and source file are no longer members of device_t, they are part of the device type * MACHINE_COFIG_START no longer needs a driver class * MACHINE_CONFIG_DERIVED_CLASS is no longer necessary * Specify the state class you want in the GAME/COMP/CONS line * The compiler will work out the base class where the driver init member is declared * There is one static device type object per driver rather than one per machine configuration Use DECLARE_DEVICE_TYPE or DECLARE_DEVICE_TYPE_NS to declare device type. * DECLARE_DEVICE_TYPE forward-declares teh device type and class, and declares extern object finders. * DECLARE_DEVICE_TYPE_NS is for devices classes in namespaces - it doesn't forward-declare the device type. Use DEFINE_DEVICE_TYPE or DEFINE_DEVICE_TYPE_NS to define device types. * These macros declare storage for the static data, and instantiate the device type and device finder templates. The rest of the changes are mostly just moving stuff out of headers that shouldn't be there, renaming stuff for consistency, and scoping stuff down where appropriate. Things I've actually messed with substantially: * More descriptive names for a lot of devices * Untangled the fantasy sound from the driver state, which necessitates breaking up sound/flip writes * Changed DECO BSMT2000 ready callback into a device delegate * Untangled Microprose 3D noise from driver state * Used object finders for CoCo multipak, KC85 D002, and Irem sound subdevices * Started to get TI-99 stuff out of the TI-990 directory and arrange bus devices properly * Started to break out common parts of Samsung ARM SoC devices * Turned some of FM, SID, SCSP DSP, EPIC12 and Voodoo cores into something resmbling C++ * Tried to make Z180 table allocation/setup a bit safer * Converted generic keyboard/terminal to not use WRITE8 - space/offset aren't relevant * Dynamically allocate generic terminal buffer so derived devices (e.g. teleprinter) can specify size * Imporved encapsulation of Z80DART channels * Refactored the SPC7110 bit table generator loop to make it more readable * Added wrappers for SNES PPU operations so members can be made protected * Factored out some boilerplate for YM chips with PSG * toaplan2 gfx * stic/intv resolution * Video System video * Out Run/Y-board sprite alignment * GIC video hookup * Amstrad CPC ROM box members * IQ151 ROM cart region * MSX cart IRQ callback resolution time * SMS passthrough control devices starting subslots I've smoke-tested several drivers, but I've probably missed something. Things I've missed will likely blow up spectacularly with failure to bind errors and the like. Let me know if there's more subtle breakage (could have happened in FM or Voodoo). And can everyone please, please try to keep stuff clean. In particular, please stop polluting the global namespace. Keep things out of headers that don't need to be there, and use things that can be scoped down rather than macros. It feels like an uphill battle trying to get this stuff under control while more of it's added.
