* emumem: Simplify memory management. [O. Galibert] Olivier Galibert2020-11-027-20/+8
| | | | | | | | | | | | | | | | | | | | API impact: - install_ram/rom/writeonly now requires a non-null pointer. If you want automatically managed ram, add it to a memory map, not in machine_start - install_*_bank now requires a memory_bank *, not a string - one can create memory banks outside of memory maps with memory_bank_creator - one can create memory shares outside of memory maps with memory_share_creator Memory maps impact: - ram ranges with overlapping addresses are not shared anymore. Use .share() - ram ranges touching each other are not merged anymore. Stay in your range Extra note: - there is no need to create a bank just to dynamically map some memory/rom. Just use install_rom/ram/writeonly

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.

* devcb3 Vas Crabb2018-07-071-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are multiple issues with the current device callbacks: * They always dispatch through a pointer-to-member * Chained callbacks are a linked list so the branch unit can't predict the early * There's a runtime decision made on the left/right shift direction * There are runtime NULL checks on various objects * Binding a lambda isn't practical * Arbitrary transformations are not supported * When chaining callbacks it isn't clear what the MCFG_DEVCB_ modifiers apply to * It isn't possible to just append to a callback in derived configuration * The macros need a magic, hidden local called devcb * Moving code that uses the magic locals around is error-prone * Writing the MCFG_ macros to make a device usable is a pain * You can't discover applicable MCFG_ macros with intellisense * Macros are not scoped * Using an inappropriate macro isn't detected at compile time * Lots of other things This changeset overcomes the biggest obstacle to remving MCFG_ macros altogether. Essentially, to allow a devcb to be configured, call .bind() and expose the result (a bind target for the callback). Bind target methods starting with "set" repace the current callbacks; methods starting with "append" append to them. You can't reconfigure a callback after resolving it. There's no need to use a macro matching the handler signatures - use FUNC for everything. Current device is implied if no tag/finder is supplied (no need for explicit this). Lambdas are supported, and the memory space and offset are optional. These kinds of things work: * .read_cb().set([this] () { return something; }); * .read_cb().set([this] (offs_t offset) { return ~offset; }); * .write_cb().set([this] (offs_t offset, u8 data) { m_array[offset] = data; }); * .write_cb().set([this] (int state) { some_var = state; }); Arbitrary transforms are allowed, and they can modify offset/mask for example: * .read_cb().set(FUNC(my_state::handler)).transform([] (u8 data) { return bitswap<4>(data, 1, 3, 0, 2); }); * .read_cb().set(m_dev, FUNC(some_device::member)).transform([] (offs_t &offset, u8 data) { offset ^= 3; return data; }); It's possible to stack arbitrary transforms, at the cost of compile time (the whole transform stack gets inlined at compile time). Shifts count as an arbitrary transform, but mask/exor does not. Order of mask/shift/exor now matters. Modifications are applied in the specified order. These are NOT EQUIVALENT: * .read_cb().set(FUNC(my_state::handler)).mask(0x06).lshift(2); * .read_cb().set(FUNC(my_state::handler)).lshift(2).mask(0x06); The bit helper no longer reverses its behaviour for read callbacks, and I/O ports are no longer aware of the field mask. Binding a read callback to no-op is not supported - specify a constant. The GND and VCC aliases have been removed intentionally - they're TTL-centric, and were already being abused. Other quirks have been preserved, including write logger only logging when the data is non-zero (quite unhelpful in many of the cases where it's used). Legacy syntax is still supported for simple cases, but will be phased out. New devices should not have MCFG_ macros. I don't think I've missed any fundamental issues, but if I've broken something, let me know.

* Streamline machine configuration macros - everyone's a device edition. Vas Crabb2018-05-063-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Start replacing special device macros with additional constructors, starting with ISA, INTELLEC 4 and RS-232 buses. Allow an object finder to take on the target of another object finder. (For a combination of the previous two things in action, see either the INTELLEC 4 driver, or the Apple 2 PC Exporter card. Also check out looping over a device finder array to instantiate devices in some places. Lots of things no longer need to pass tags around.) Start supplying default clocks for things that have a standard clock or have all clocks internal. Eliminate the separate DEV versions of the DEVCB_ macros. Previously, the plain versions were a shortcut for DEVICE_SELF as the target. You can now supply a string tag (relative to current device being configured), an object finder (takes on the base and relative tag), or a reference to a device/interface (only do this if you know the device won't be replaced out from under it, but that's a safe assumption for your subdevices). In almost all cases, you can get the effect you want by supplying *this as the target. Eliminate sound and CPU versions of macros. They serve no useful purpose, provide no extra checks, make error messages longer, add indirection, and mislead newbies into thinking there's a difference. Remove a lot of now-unnecessary ":" prefixes binding things relative to machine root. Clean up some miscellaneous rot. Examples of new functionality in use in (some more subtle than others): * src/mame/drivers/intellec4.cpp * src/mame/drivers/tranz330.cpp * src/mame/drivers/osboren1.cpp * src/mame/drivers/zorba.cpp * src/mame/devices/smioc.cpp * src/devices/bus/a2bus/pc_xporter.cpp * src/devices/bus/isa/isa.h * src/devices/bus/isa/isa.h * src/devices/bus/intellec4/intellec4.h
* Make MCFG_DEVICE_ADD and callable device types more flexible: Vas Crabb2018-05-047-36/+41
| | | | | | | | | | | | | | | | | | | | | * Allows defaulted clocks (see subtle example with vboy) * Allows additional constructors (see RS232 port in tranz330) * Allows use of device finder in place of tag in MCFG_DEVICE_ADD * Requires out-of-line destructor for devices using incomplete types * Requires XTAL or explicit u32 for clocks for devices with private types Devices must still define the standard constructor. When writing additional constructors, be aware that the constructor runs before device_add_mconfig in the context of the existing device, not the new device. See osborne1, zorba, tranz330, and vboy for examples of this in use. Compilation is a bit slower, but this is temporary while refactoring is in progress. Eliminated the need for MCFG_SOUND_ROUTE_EX. Removed macros from slot option configuration - they just obfuscated code and slowed it down with needless dynamic casts, but didn't actually simplify it.

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 Crabb2017-05-225-10/+10
| | | | | | | | | (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.
* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-1432-425/+372
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Changes to make get_default_card_software() less stupid Nathan Woods2017-04-102-2/+2
| | | | | | | | | | The goals with this change is to make get_default_card_software() a bit more standalone by making it a const method that does not mutate the state of the device_image_interface. This is done by passing in a small structure that encapsulates the minimum of information that get_default_card_software() needs. This also eliminates the need for device_image_interface::open_image_file() I agree with Sarayan that get_default_card_software() is terrible and needs to ultimately go away. This is a small step in that direction. Lastly, I don't care for the name of get_default_card_software_hook (or get_default_card_software() for that matter). If anybody has better ideas, let me know.

The software_entry() accessor is still provided, but now rarely used. - Eliminate two of the three arguments to load_software_part. - Remove some unnecessary auto-typing in ui/inifile.cpp.
* Remove emu.h from headers (nw) Olivier Galibert2017-02-1118-2/+16
| | | | | | | | | | | | 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.
