| | | | 6/vrender0/wave/x1_010: update to new stream callbacks
* Significant internal changes to sound streams (#7169)GravatarGravatar Aaron Giles2020-09-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Significant internal changes to sound streams: Abstracted buffers of sound data into an internal stream_buffer class, with helper classes read_stream_view and write_stream_view which offer readable/writable "views" into the buffers Internal sound calculations are all done using stream_buffer::sample_t, which is a 32-bit float; existing callbacks are supported through an adapter that converts to/from signed 32-bit integers Improved behavior of dynamic stream sample rate changes to resample a short runway of data to preserve continuity across transitions Created a new stream update callback which passes a std::vector of read_stream_views for inputs, and a std::vector of write_stream_views for outputs Updated core mixer and speaker devices to the new stream update callback Updated the following sound cores to the new stream update callback: ay8910, dac, k054539, msm5205, namco, netlist, okim6295, pokey, samples, sn76496, sp0250, tms5220, tms57002, upd7759, vgm_visualizer, volt_reg Changed existing stream update callback to make inputs explicitly const and the output pointers const as well, since they are re-used across calls; fixed several engines that violated this rule Sound_manager::stream_alloc can no longer automatically connect to a device's sound_stream_update callback; instead, the stream_alloc() on the sound_device_interface should be called; updated many violators of this rule Streams can be created with SAMPLE_RATE_OUTPUT_ADAPTIVE, which dynamically tracks the sample rate of its first downstream output, or with SAMPLE_RATE_INPUT_ADAPTIVE, which tracks the sample rate of its first input Changed resampling to be a separate sound_stream that is invoked as needed, opening the path for selectable resampling implementations Added a flags parameter to the new stream allocation method that allows you to specify a that input streams should not be resampled Exposed stream_input and stream_output classes directly, simplifying access to user gains and stream names Added a simple dynamic compressor to sound_manager to provide nicer results when overdriven sound happens; compression does not affect speaker_report results Improved verbose speaker_report to print a graph of peaks over time More aggressive debugging enabled for now even in release builds (should be disabled prior to next release) via SOUND_DEBUG define in sound.h; report any assertions for fixing

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Set finder tag relative to current device being configured rather thanGravatarGravatar Vas Crabb2018-04-301-1/+1
| | | | | | | | | | | | | | the finder's owner. This meand you no longer need to care about the your relationship to the object being configured and a lot of ^ and : can disappear. There's a bit reduction in string pasting in macros from this. Yes, I have to make this apply to devcb etc. as well, but that's a job for another day. There's probably at least one thing broken by this where optional objects are involved. Most things can be solved by just getting rid of the now-problematic ^ and : prefixes.

* s2650: I/O modernizationGravatarGravatar AJR2017-06-221-1/+1
| | | | | - Replace fake S2650_SENSE_PORT address with line read callback (set_input_line should also work). There are still some doubts regarding whether VBLANK should be inverted in various drivers. - Replace fake S2650_CTRL_PORT and S2650_DATA_PORT addresses with... well, these aren't dedicated parallel ports, so they actually haven't gone away. They have, however, been moved to a new 1-bit address space, since the ports share the main data bus and are distinguished from each other by an address line.
* Move static data out of devices into the device types. This is a ↵GravatarGravatar Vas Crabb2017-05-141-78/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)GravatarGravatar Olivier Galibert2017-02-111-1/+0
| | | | | | | | | | | | 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.

* Devfind revision phase 1, cleaning out some legacy stuffGravatarGravatar AJR2016-04-071-5/+4
| | | | | | | | - 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.
