| * machine/latch8.cpp: Clean up a little. Vas Crabb2021-06-241-31/+31
| | | | | | | | | | | | | | | | | | Making the bit read functions honour the XOR mask is easy in theory, but dkong.cpp is doing scary things with the XOR mask and bit read handlers on one of its latches, so it could end up breaking something. Honouring the read callbacks would add two tests to each of the bit read functions, which could hurt performance. The whole design of this device seems somewhat incoherent.

| | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Memory unit masking and address mirroring fixes (nw) AJR2017-03-251-2/+1
| | | | | | - Fix a bug which effectively treated AM_MIRROR as AM_SELECT when applied to a single-address range mirrored into a contiguous block. The automatic expansion of zero address masks now only applies to those stemming from (default) configuration, not from optimization. (This allows the assertion in latch8_device to be reinstated.) - Fix a bug where AM_SELECT applied to narrow-width handlers with a submaximal number of subunits would select the wrong address bits or none at all. (This allows rpunch_gga_w to be WRITE8 as intended.) - Add more stringent appropriateness checking of unit masks for narrow-width handlers.
* latch8, discrete: Major device cleanup (nw) (#2187) ajrhacker2017-03-251-106/+41
| | | | | | | - Eliminate the AM_LATCH8_XXX address map macros. The normal DEVREAD/DEVWRITE ought to be good enough. - Eliminate the "offset" specifications from latch8_device. This was used mostly to funnel outputs to discrete_device, which now has a templated write_line handler. (Inputs can use MCFG_DEVCB_RSHIFT instead.) - Organize latch8_device's callbacks as arrays of devcb_readline/devcb_writeline, helping simplifying code greatly. - Change latch8_device::bit[0-7]_(q_)?r to be proper line read handlers. This requires two extra READ8 handlers in audio/dkong.cpp, but memory-mapping for the MCS-48 T0 and T1 lines is totally artificial anyway. - Comment out an assert that now tends to fail due to buggy AM_MIRROR behavior.
* 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.
