* Make devdelegate more like devcb for configuration. This is a Vas Crabb2019-10-261-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fundamental change to show device delegates are configured. Device delegates are now aware of the current device during configuration and will resolve string tags relative to it. This means that device delegates need a device to be supplied on construction so they can find the machine configuration object. There's a one-dimensional array helper to make it easier to construct arrays of device delegates with the same owner. (I didn't make an n-dimensional one because I didn't hit a use case, but it would be a simple addition.) There's no more bind_relative_to member - just call resolve() like you would for a devcb. There's also no need to cast nullptr when creating a late bind device delegate. The flip side is that for an overloaded or non-capturing lambda you'll need to cast to the desired type. There is one less conditional branch in the hot path for calls for delegates bound to a function pointer of member function pointer. This comes at the cost of one additional unconditional branch in the hot path for calls to delegates bound to functoids (lambdas, functions that don't take an object reference, other callable objects). This applies to all delegates, not just device delegates. Address spaces will now print an error message if a late bind error is encountered while installing a handler. This will give the range and address range, hopefully making it easier to guess which memory map is faulty. For the simple case of allowing a device_delegate member to be configured, use a member like this: template <typename... T> void set_foo(T &&...args) { m_foo_cb.set(std::forward<T>(args)...); } For a case where different delegates need to be used depending on the function signature, see src/emu/screen.h (the screen update function setters). Device delegates now take a target specification and function pointer. The target may be: * Target omitted, implying the current device being configured. This can only be used during configuration. It will work as long as the current device is not removed/replaced. * A tag string relative to the current device being configured. This can only be used during configuration. It will not be callable until .resolve() is called. It will work as long as the current device is not removed/replaced. * A device finder (required_device/optional_device). The delegate will late bind to the current target of the device finder. It will not be callable until .resolve() is called. It will work properly if the target device is replaced, as long as the device finder's base object isn't removed/replaced. * A reference to an object. It will be callable immediately. It will work as long as the target object is not removed/replaced. The target types and restrictions are pretty similar to what you already have on object finders and devcb, so it shouldn't cause any surprises. Note that dereferencing a device finder will changes the effect. To illustrate this: ... required_device<some_device> m_dev; ... m_dev(*this, "dev") ... // will late bind to "dev" relative to *this // will work if "dev" hasn't been created yet or is replaced later // won't work if *this is removed/replaced // won't be callable until resolve() is called cb1.set(m_dev, FUNC(some_device::w)); ... // will bind to current target of m_dev // will not work if m_dev is not resolved // will not work if "dev" is replaced later // will be callable immediately cb2.set(*m_dev, FUNC(some_device::w)); ... The order of the target and name has been reversed for functoids (lambdas and other callable objects). This allows the NAME macro to be used on lambdas and functoids. For example: foo.set_something(NAME([this] (u8 data) { m_something = data; })); I realise the diagnostic messages get ugly if you use NAME on a large lambda. You can still give a literal name, you just have to place it after the lambda rather than before. This is uglier, but it's intentional. I'm trying to drive developers away from a certain style. While it's nice that you can put half the driver code in the memory map, it detracts from readability. It's hard to visualise the memory range mappings if the memory map functions are punctuated by large lambdas. There's also slightly higher overhead for calling a delegate bound to a functoid. If the code is prettier for trivial lambdas but uglier for non-trivial lambdas in address maps, it will hopefully steer people away from putting non-trivial lambdas in memory maps. There were some devices that were converted from using plain delegates without adding bind_relative_to calls. I fixed some of them (e.g. LaserDisc) but I probably missed some. These will likely crash on unresolved delegate calls. There are some devices that reset delegates at configuration complete or start time, preventing them from being set up during configuration (e.g. src/devices/video/ppu2c0x.cpp and src/devices/machine/68307.cpp). This goes against the design principles of how device delegates should be used, but I didn't change them because I don't trust myself to find all the places they're used. I've definitely broken some stuff with this (I know about asterix), so report issues and bear with me until I get it all fixed.

* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-141-19/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* 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.

* Memory fun [O.Galibert] Olivier Galibert2016-06-141-6/+6
| | | | | | | | | | | | | | | | | | | | | - Added AM_SELECT/addrselect field. Replaces the old AM_MIRROR/AM_MASK combo used to mirror a handler and get the mirrored bits in the offset. - Removed mask and/or mirror from where it didn't belong. Simplified a lot of instances of mask that just weren't needed, especially in bus handlers. Used the short forms of install handlers where possible. - Replaced the 60s hippy, "It's cool man" range parameter handling in map_range that tried to guess what was meant when the values passed were not entirely sensible, by a cranky, diner waitress-turned IRS auditor curmudgeon. Main control function has a series of 14 tests just to find a reason to fatalerror out your requests. You have been warned. Some drivers, hopefully not many, will fail the gate-guarding bureaucrat trials. Should be easy to fix actually, I worked on the error messages. A full regression test would be welcome.
* Devfind revision phase 1, cleaning out some legacy stuff AJR2016-04-071-1/+2
| | | | | | | | - Eliminate the cached device_t::m_region pointer and its region() getter method. Devices that need to bind to a region with the same tag should use optional/required_memory_region or optional/required_region_ptr with DEVICE_SELF as the subtag; this improves error checking. (DEVICE_SELF has been moved to device.h for greater visibility in the source.) - Allow required/optional_region_ptr to specify a specific length which must match that of the region found. - Implement finder_base::finder_tag() getter for diagnostic purposes. - Perform some (not very efficient) validity checks on memory region finders instead of allowing them to automatically pass. - Privatize device_memory_interface::m_addrspace.
* Iterate over core classes C++11 style AJR2016-03-311-3/+4
| | | | | | | | C++11 range-based for loops can now iterate over simple_list, tagged_list, core_options, device_t::subdevice_list, device_t::interface_list, render_primitive_list and all subclasses of the above, and much code has been refactored to use them. Most core classes that have these lists as members now have methods that return the lists themselves, replacing most of the methods that returned the object at an owned list's head. (A few have been retained due to their use in drivers or OSD.) device_t now manages subdevice and interface lists through subclasses, but has given up the work of adding and removing subdevices to machine_config. memory_manager has its tagged lists exposed, though the old rooted tag lookup methods have been removed (they were privatized already).
