* Various optimisations to code generaton. Vas Crabb2023-03-261-1/+1
| | | | | | | | | | | | | | | 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.
* Update accumulating relative inputs exactly once per frame. Vas Crabb2023-02-241-5/+5
| | | | | | | | | | | | | This fixes "amplification" effects that would happen if the frame rate rose above 100 Hz (whether by unthrottling or otherwise). Synchronise with wall clock any time inputs are read. Not doing this has weird effects on relative inputs with frame skipping and contributes to unresponsiveness of menus. Reduce visual latency for mouse movement on menus when paused or skipping frames. The rest of the code changes to menus won't provide benefits until draw can happen after event handling.
* osd: Don't pump events when reading inputs. Vas Crabb2023-02-231-0/+8
| | | | | | This was a drain on performance. If anything is trying to poll inputs in a loop, it needs to call input_update() to ensure it gets up-to-date state.
* bgfx: Refined configuration handling: Vas Crabb2023-02-021-8/+8
| | | | | | | | | | | | | * Sort screen chains by none, default, then collation order (rather than whatever order the filesystem yields). * Correctly persist settings across fullscreen toggle when explicit screen chains are configured. * If chains are specified for a single window only, apply them to all windows. * Treat empty string for screen chain as "default" rather than crashing. * Changed default setting for bgfx_screen_chains to an empty string so chain selection will be saved/restored per system with mame.ini file created by -cc with no other settings.
* osd: Fixed BGFX crash on toggling fullscreen on Linux. Vas Crabb2023-02-021-2/+2
| | | | Also fixed draw13.cpp upsetting older versions of clang.
* osd: Turned video modules into actual modules, fixed various issues. Vas Crabb2023-02-011-55/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Don't ignore the return status of OSD module initialisation. Attempt to fall back to an alternate module if the selected module fails to initialise. Log more useful diagnostic information at verbose level. Fixed BGFX crash on exit after toggling fullscreen. Also persist more settings than just the selected chains across toggling fullscreen. Turned video modules into OSD modules in the same sense as all the other OSD modules. They now use the same selection/fallback mechanism as all the other modules without special extra code in the OSD implementations. Untangled some object ownership mess. Windows own renderers, OSD objects own windows. Fixed a refrence loop that caused the first window object to always leak. Don't create renderer object until after underlying window has been created. Fixed issues with order of creation/destruction when toggling fullscreen or changing prescale in fullscreen with -switchres in SDL builds. Use more smart pointers in BGFX and Direct3D render modules. Most of the code now reutrns a smart pointer when handing over ownership or a naked pointer when retaining ownership. Fixed a few leaks and simplified cleanup code. Encapsulated various OSD modules better.
* Various input and OSD refactoring: Vas Crabb2023-01-291-23/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Miscellaneous fixes and refactoring: Vas Crabb2023-01-281-71/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ui/analogipt.cpp: Fixed bar graph display for fields with ranges that wrap through zero. emu/inputdev.cpp: Separateed analog axis deadzone and switch threshold settings, reduced default deadzone, and fixed a potential division by zero if the deadzone and saturation settings are equal. emu/ioport.cpp: Fixed behaviour of absolute analog fields where range passes through zero - it previously only worked for specific combinations of mask, minimum and default. Removed a workaround from universal/getaway.cpp that is no longer necessary. emu/input.cpp: Fixed unintuitive behaviour when an absolute field is assigned an OR combination of a relative control folled by an absolute control (e.g. Mouse X or Joy 1 LSX). Also fixed reading axis input sequences where an axis code is followed by a switch code (these can only be produced by manually editing configuration files, not through MAME's UI), and fixed the returned type when multiple relative axes sum to zero. osd/modules/input_dinput.cpp: Fixed hat switches being stuck in up position when input is suspended in the background taito/taitoio_yoke.cpp: Give throttle control a distinct type, and don't auto-centre. osd: Added option to select MIDI provider module (currently only PortMidi and the dummy module are available). Also put various things in namespaces, and fixed builds including SDL sound module with native Windows OSD. emu/validity.cpp: Added check to catch I/O port fields using UI input types. emu/inpttype.ipp: Renamed inputs that were causing confusion. "Bill" and "Track" were causing confusion for translators and hence likely causing confusion for many users, especially those who are not native English speakers. "Track" as an abbreviation for "Trackball" was frequently being mistranslated, e.g. in the sense of a CD track selection button or even in the sense of a railway track. There's no reason to abbreviate it. "Bill" in the US English sense as a banknote is too ambiguous and was causing confusion for translators. It's better to use the less ambiguous "Banknote". Corrected Greek translations of "Trackball". Don't run GitHub Actions on issue template changes.

| | | | | | | | | | | | | | | | | it default with SDL. This changes behaviour, however I think it's a net positive: * Most games using Steam Input or SDL2 to read game controllers have this behaviour, so users have come to expect it. * This module is better at giving meaningful names to buttons on common controller, and assigning axes consistently. * Button/axis mapping files using a widely-used format are supported. * The old behaviour is still available with `-joystickprovider sdljoy` if anyone wants it. The new option for controller mapping files is in the general OSD options rather than SDL options as it can be extended to DirectInput in the future.
* -osd: Better XInput and SDL game controller input enhancements: Vas Crabb2023-01-121-1/+2
| | | | | | | | | | | | | | | * Added initial support for XInput controller subtypes, starting with driving, arcade and flight controllers. * Check XInput capabilities to ignore buttons and hats that aren't present. * Added preliminary SDL Game Controller joystick provider. Reconnection and mixed Game Controller/Joystick devices are unsupported. * Show the input token for the highlighted control on input device menus. -ui: Allow menus to set required space above and below menu when metrics change. Fixes the initial bad layout on the system selecton menu, or bad layout after resizing windows.

* Patched up some gaps in functionality and fixed some bugs. Vas Crabb2022-09-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ui: Added some missing functionality: * Added an option to copy input device IDs to the relevant menus. * Added an item for setting the software lists files path (-hashpath) to the folder setup menu. * Allow pasting text from clipboard in most places that allow typing (searching, entering filenames, entering barcodes). * Changed the software selection menu heading to be a bit less misleading. * Made barcode menu less eager to rebuild itself unnecessarily, and removed some confusing and apparently pointless code. Exposed more Lua bindings: * Added low-level palette objects. * Added indexed bitmap types. * Added a bitmap method for extracting pixels from a rectangular area as a packed binary string. * Changed screen device pixels method to return width and height in addition to the pixels. osd: Added some functionality and cleaned up a little: * Added a function for copying text to the clipboard. * Moved function for converting Windows error codes to standard error conditions to winutil.cpp so it can be used from more places. * Removed duplicate declaration of osd_get_clipboard_text and made the function noexcept (including fixing implementations). * Made macOS implementation of osd_get_clipboard_text skip the encoding conversion if it finds UTF-8 text first. * Changed the default -uimodekey setting so it doesn't lose the "not shift" that stops the default from interfering with UI paste. Various bug fixes: * util/unicode.cpp: Fixed the version of utf8_from_uchar that returns std::string blowing up on invalid codepoints. * util/bitmap.h: Fixed wrapping constructors for indexed bitmaps taking the wrong parameter type (nothing was using them before). * util/bitmap.cpp: Fixed potential use-after-free issues with bitmap palettes. * emu/input.cpp, emu/inputdev.cpp: Log 1-based device numbers, matching what's shown in the internal UI and used in tokens in CFG files. * emu/emumem.cpp: Added the bank tag to a fatal error message where it was missing. docs: Reworked and expanded documentation on configuring stable controller IDs. For translators, the changes are quite minor: * There's a menu item for copying a device ID to the clipboard, and associated success/failure messages. * There's the menu item for setting the software list file search path. * One of the lines in the software selection menu heading has changes as it could be interpreted as implying it showed a software list name.
* OSD/network interface cleanup AJR2022-08-281-0/+1

| | | | | | | | | | | | | | | - 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
* Got rid of global_alloc/global_free. Vas Crabb2020-10-031-10/+10
| | | | | | | | | | | | | | | | | | | | | | | | | The global_alloc/global_free functions have outlived their usefulness. They don't allow consistently overriding the default memory allocation behaviour because they aren't used consistently, and we don't have standard library allocator wrappers for them that we'd need to use them consistently with all the standard library containers we're using. If you need to change the default allocator behaviour, you can override the new/delete operators, and there are ways to get more fine-grained control that way. We're already doing that to pre-fill memory in debug builds. Code was already starting to depend on global_alloc/global_free wrapping new/delete. For example some parts of the code (including the UI and Windows debugger) was putting the result of global_alloc in a std::unique_ptr wrappers without custom deleters, and the SPU sound device was assuming it could use global_free to release memory allocated with operator new. There was also code misunderstanding the behaviour of global_alloc, for example the GROM port cartridge code was checking for nullptr when a failure will actually throw std::bad_alloc. As well as substituting new/delete, I've made several things use smart pointers to reduce the chance of leaks, and fixed a couple of leaks, too.

* Make osd_printf_* use util/strformat semantics. Vas Crabb2019-09-261-17/+20
| | | | | | | | | | | | | | | | | (nw) This has been a long time coming but it's here at last. It should be easier now that logerror, popmessage and osd_printf_* behave like string_format and stream_format. Remember the differences from printf: * Any object with a stream out operator works with %s * %d, %i, %o, %x, %X, etc. work out the size by magic * No sign extending promotion to int for short/char * No widening/narrowing conversions for characters/strings * Same rules on all platforms, insulated from C runtime library * No format warnings from compiler * Assert in debug builds if number of arguments doesn't match format (nw) Also removed a pile of redundant c_str and string_format, and some workarounds for not being able to portably format 64-bit integers or long long.

Before pushing, please check that what you're about to push is sane. Check your local commit log and ensure there isn't anything out-of-place before pushing to mainline. When things like this happen, it wastes everyone's time. I really don't need this in a week when real work™ is busting my balls and I'm behind where I want to be with preparing for MAME release.

| | | | | | | | This shader uses the equation described by R. Keys in the paper 'Cubic Convolution Interpolation for Digital Image Processing' which is, in this case, the same as a Catmull-Rom spline. This produces a sharper upscaled image than bilinear filtering. The new shader is selected by setting gl_glsl_filter to 2. Consequently, gl_glsl_filter is now treated as an int rather than a boolean. Also fixed a variable name problem in the code guarded by GLSL_SOURCE_ON_DISK.
