| | | | | | | | | | - Simplify handler signatures - Rename cd_ab_r/w and ba_cd_inv_r/w to dc_ab_r/w and ab_dc_r/w to be more hardware-accurate - Eliminate cd_ba_r/w and ba_cd_r/w (no legitimate uses in existing code) mvme162: Fix SCC addressing (nw) Note that the SCC's address inputs are A/~B and D/~C, rather than the Z80 SIO's B/~A and C/~D.

| | | | | | | | | | | | | 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.

| | | | | | | | | | | | * interpro: headless boot working These fixes enable booting and CLIX installation on headless InterServe systems (InterPro systems without graphics) using a VT100 or VT220 compatible terminal on serial port 2 (0 for ip6000).

* diexec: Interrupt API changes (nw) AJR2018-05-181-1/+1
| | | | | | - PULSE_LINE is no longer a value. Existing uses have been changed to pulse_input_line with attotime::zero as the second argument. - Formerly only INPUT_LINE_NMI and INPUT_LINE_RESET were allowed with PULSE_LINE. INPUT_LINE_NMI no longer receives special handling; instead, CPU devices must specify which of their input lines are edge-triggered and thus may be used with zero-width pulses by overriding the execute_input_edge_triggered predicate. INPUT_LINE_RESET is still special-cased, however. - execute_default_irq_vector now allows a different default vector to be specified for each input line. This added flexibility may or may not prove useful.

So creating a device then configuring through a fragment doesn't work as-is. The simplest solution is just to add a MCFG_DEVICE_MODIFY at the start of the fragment with the correct tag.

* Goodbye MACHINE_CONFIG_FRAGMENT, it was nice knowing you. Vas Crabb2017-05-221-1/+1
| | | | | | | | | (nw) This is a pretty minimal change. The point where the root device is added has been moved from the MACHINE_CONFIG_START macro to the constructor of the machine configuration class (made possible by giving drivers their own device types). This isn't the final change in this area. The root device is still being handled specially in that its configuration comes from the game driver structure. This needs to be harmonised with regular devices. But that's a job for another day.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This helps catch headers that don't #include things that they use.
* Remove emu.h from headers (nw) Olivier Galibert2017-02-111-0/+1
| | | | | | | | | | | | Per Vas' request. If the compile fails for you (i'm thinking osx and windows native debuggers here in particular), add '#include "emu.h"' as first include of the cpp files that fail. Due to our use of precompilation and forced inclusion, emu.h must be included as the very first non-comment thing we do if we want to be sure msvc compiles are identical to gcc/clang ones. Doing it directly instead of through an include increases the correctness probability by a magnitude.
