| | | | callback types. timer_callback is a class containing a timer_expired_delegate plus a user-supplied pointer, and accounting information for registration. timer_instance is a single active timer in the scheduler. persistent_timer is what you get back from timer_alloc() now, and has methods for dynamic changes. transient_timer_factory is what you use to create transient timers. Devices now own a transient_timer_factory for transient device timers. persistent_timers can be emedded and initialized directly.

* (nw) Clean up the mess on master Vas Crabb2019-03-261-2/+2
| | | | | | | | | | | | | This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at 598cd5227223c3b04ca31f0dbc1981256d9ea3ff. 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.

* 6821pia, 6840ptm, 6850acia, bus/ss50, cmi01a: Simplify read/write handlers (nw) AJR2019-02-181-2/+2

* 6840: fix dual byte mode once again (nw) (#4081) dxl2018-10-071-8/+17
| | | | | | | | | | | | * 6840: fix dual byte mode once again (nw) Two problems in dual byte mode: - the high time flag is the same for all counters - high time flag is reset on each counter reload, but should only be reset if the timer is reload by the user. * 6840: fix dual byte mode once again (nw)
* Details, details (nw) Vas Crabb2018-09-011-3/+6
| | | | | | | | * It's generally not a great idea to do integer ops on bool - it implicitly casts to/from int and may perform poorly * Get rid of required ram_device in atari 8-bit common state - it isn't required/used by bartop52 * Get rid of bogus RAM device in bartop52 * Restore some authors' stylistic choices * Make some stuff more consistent
* Fix output pins in Dual 8 bit mode (nw) Sven Schnelle2018-08-311-8/+27
| | | | | | In Dual 8 bit mode the output isn't inverted on every TC, instead it's low until the count reaches 0xff, and high afterwards.
* 6840ptm: fix divide by 8 mode Sven Schnelle2018-06-231-0/+4
| | | | | | | | In divide by 8 mode the value computed in compute_counter() is wrong because the function doesn't divide the clock before the calculation. Signed-off-by: Sven Schnelle <svens@stackframe.org>
* 6840ptm: Counter/timers are numbered from 1 to 3, not 0 to 2 as with 8253 (nw) AJR2018-02-201-17/+17
| | | | | | - Rename OUT0, OUT1 and OUT2 callback configuration macros to match pin names (O1, O2 and O3) - Update all verbose logging messages to be one-based - Remove unnecessary mentions of device type in logging messages
* 6840ptm: Stop defaulting external clocks to 1 Hz AJR2018-02-191-22/+11
| | | | - duet16: Fully configure MC6840 timer to pass self-test; FDC is also mapped now but fails (nw)
* Candela PAL driven address map (#2657) Joakim Larsson Edström2017-09-191-0/+1
| | | | | | | | | | * mc6840ptm/mc6850acia: fixed so that LOG_OUTPUT_FUNC can be defined as printf * can09t: replaced static address map with a PAL driven address map enabling several BASIC commands previously failing * logmacro.h: Added support for C++ output streams using LOG_OUTPUT_STREAM instead of using printf as LOG_OUTPUT_FUNC [Vas] * 6840: removed c_str() in LOG statements

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Self-registering devices prep: Vas Crabb2017-02-271-1/+1
| | | | | | | | | | | | | | * Make device_creator a variable template and get rid of the ampersands * Remove screen.h and speaker.h from emu.h and add where necessary * Centralise instantiations of screen and speaker finder templates * Add/standardise #include guards in many hearers * Remove many redundant #includes * Order #includesr to help catch headers that can't be #included alone (nw) This changes #include order to be prefix, unit header if applicable then other stuff roughly in order from most dependent to least dependent library. This helps catch headers that don't #include things that they use.
