Next Steps: * We're going to move the terminal from the r9751 into the SMIOC, and hook it up to the DMA controllers as a hacky temporary solution. * We need to emulate the 5xxxx memory range in SMIOC to proxy data to/from the 68k memory * Then we'll start work on emulating the octal uart properly and hooking it up to RS232 channels. commit ca91614fca3f43d87755d0c3439521276d7bfafb Author: Stephen Stair <sgstair@akkit.org> Date: Wed Mar 14 19:52:04 2018 -0700 Tinkering to get SMIOC further along 1) Enable 188 cpu to advance DMA immediatley if DRQ is held high when source synchronous DMA is started (It's not clear whether the DMA actually works this way yet) 2) Retrigger the DMA DRQ when a memory access is made to the DMA window (future work needed to proxy the reads/writes to the 68k's main memory) This is needed to support multibyte DMA reads/writes to the 68k window. 3) Reverse the bytes in the status register (based on current incomplete understanding of how this is encoded) 4) Connect the status register back to the r9751 on SMIOC status read Current state: SMIOC's main board DMA state machine now completes the DMA transfer from the main board (With incorrect data), but we are still getting stuck. Next steps: SMIOC is now hanging waiting on DMA to UART to complete, we need to implement some emulation of the UART and its connections to the surrounding 16 dma channels in order to make progress. commit 62c1455c97a53ed970622e08cb03a225625914fd Author: Stephen Stair <sgstair@akkit.org> Date: Sun Mar 4 20:13:32 2018 -0800 Progress on emulating SMIOC commit daee8498c5840417aee3ed9def0acfba5476335a Author: Stephen Stair <sgstair@akkit.org> Date: Sun Feb 25 20:02:32 2018 -0800 Working on bringing up SMIOC Trying to get emulated SMIOC in lockstep with the main 68k. commit 5a929fde90307040a0544682888f2f21a914b900 Author: Stephen Stair <sgstair@akkit.org> Date: Wed Feb 21 20:06:27 2018 -0800 re-enable SMIOC, Logging improvements, first steps towards emulating on-board hardware. commit f0c7a1665a18c99df5527ae45994f39f95223814 Author: Stephen Stair <sgstair@akkit.org> Date: Sun Feb 11 16:26:31 2018 -0800 Emulation fix - Terminal now responds to input commit ecff4035f3fdaa0329df46f99ccd516aa23ec8af Author: Stephen Stair <sgstair@akkit.org> Date: Tue Feb 6 19:00:35 2018 -0800 Hacky emulation of SMIOC now successfully receiving serial characters! commit 376bca90dff311d24e1f5014d8d6f0dc297bf671 Author: Stephen Stair <sgstair@akkit.org> Date: Sun Jan 28 18:31:38 2018 -0800 Experimenting with SMIOC emulation * Partial fixes for line state issues with persistent line values When the AM9517 DMA controller mode is updated to change the polarity of DACK/DREQ, it doesn't update the DACK line values / request values (respectively). This fixes this issue for one of the emulated devices in the file, but the other device has the same problem. * Add skeleton of SCC2698B UART device * Early progress on emulating SCC2698B Octal UART Core structure for IO lines and writing registers is in place. * Update address maps to new format. * SCC2698b: Add tx/rx, baud rate generation * Emulation improvements for scc2698b device * MPP output pins emulated * Improved logging for baud rate changes * Channel configuration emulated * Support for TX/RX Enable * Started integrating new features into SMIOC * Minor progress on the path to enabling new UART for SMIOC * Resolved code issues related to upstream changes * Working around an apparent problem with callbacks on sub-device devices * Terminal added for serial port attached to SCC2698B UART. * Things compile and seem to work. * SMIOC: Serial is now outputting correctly through emulated SMIOC Some glitches to work out, but this is nearly ready. * AM9517a should not forget about input line status on master reset. * Disable tracing * SMIOC: Improving diagnostics and making some progress on the emulation * Revised tracing in SMIOC and SCC2698B * Improved tracing approach in r9751 * Minor progress towards working SMIOC emulation. * [R9751] Update drivers to new code patterns after rebase Rebased on latest mame, Fixed a few issues and updated the callback code patterns based on recent changes in devcb * [R9751] Improve logging, fix interrupt race Serial no longer drops output characters * [R9751] Working on SMIOC emulation Improved SMIOC emulation accuracy, Made some progress in getting through the disktool initialization sequence, but we are still hitting a problem - It looks like disktool should be resetting the SMIOC board when it starts, but the mechanism for this has not been found. * [R9751] Improve tracing for system board registers * [R9751] Improve SMIOC emulation Still having some trouble with SMIOC but this seems to be an improvement. SMIOC is now waiting for a status to be read before applying a new status, and mandatory parameter read logic is in place. * [R9751] Incremental emulation improvements the SMIOC failure was understood and fixed, and a new approach to getting the hardware to bootstrap correctly was implemented - Still having some problems with it though. * [R9751] Fixed emulation issues * Disktool now boots to the console * UART receive only partly working, I don't think it's fully connected yet. * [R9751] Further progress on SMIOC emulation * Figured out the missing command parameter interface to the SMIOC board * Still blocked because the SMIOC interface to the breakout board through an onboard 8051 is not emulated and the disktool software depends on properties coming from it. * [R9751] Terminal is fully working for disktool * Improved the emulation of the 80188 to 451 connection in order to reliably set a status bit disktool depends on. * [R9751] Fix build after rebase * [R9751] Cleanup, tracing improvements * Remove second emulated terminal - SMIOC is now stable enough to run the terminal. * Remove older and unnecessary emulation/tracing code * r9751: Fix compile error and modify copyright holders

* devcb3 Vas Crabb2018-07-071-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-141-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Galibert2017-02-111-1/+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.
