* coco_fdc: Allow FLEX to work on CoCo machines (#11329) Michael R. Furman2023-06-111-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two parts to the change. First is a correction to the coco_fdc hardware emulation. Second is file format ordering adjustments wich make things easier for using FLEX on CoCos. For the hardware change: Before the change FLEX was unable to boot on CoCo machines. The behaviour and troubleshooting showed that while the FLEX kernel started up it was unable to read anything from Track 0. Standard FLEX disks have SD(FM) on Track 0, and the remainder of the disks (for CoCo FLEX) are normally DD(MFM) or could also be SD(FM). The bug was in the handling of the WDC FDC's INTRQ line. Reviewing the available documentation and schematics showed that when the FDC asserts INTRQ two things happen. NMI is asserted on the CoCo bus and the HALT signal is cleared. The MAME code added an incorrect condition on clearing HALT: It only happened when Double-Density operation was selected. This change fixes the logic to work the same way as is shown in the schematics, that HALT is cleared any time INTRQ is asserted. SD(FM) disk operations work properly and FLEX boots completely and runs correctly after making this change. File Format Ordering Adjustments: This part of the change makes it easiser to use FLEX in CoCo emulation with a wider variety of FLEX-formatted disk images. The issue here is that due to the way the JVC disk format works it winds up being a catch-all for disk images. Because FLEX has specific formatting requirements and code to handle this and JVC has no support for this special formatting, FLEX formats along with DMK and SDF are moved to come before JVC in the formats list. This allows a wider variery of FLEX-formatted disk images to be properly detected. The DMK disk image from the following recent restoration of FHL Color FLEX was used for testing: https://archive.org/details/color-flex-5.0.4-frank-hogg-laboratory

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Crabb2018-05-041-3/+4
| | | | | | | | | | | | | | | | | | | | | * 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.
* Sarayan made me do it. Vas Crabb2018-04-281-6/+10
| | | | | | | | | | Concrete device types now have a call operator that instantiates a device. This change means you *must* use DECLARE_DEVICE_TYPE to declare the public interface of your device, even if it's device_t. If you want to use private implementation classes, use DEFINE_DEVICE_TYPE_PRIVATE and instantiate the object finders.

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.

* fixing/improving metadata on CoCo FDCs: CP-450 and CD-6809 Felipe Corrêa da Silva Sanches2017-11-301-9/+14
| | | | | | | | Thanks to Daniel Campos & Datassette.org for the CP-450 disk rom. MAME was calling it CP400_FDC, but the correct name of the disk controller unit is "Prológica CP-450". The ROM was correct (verified checksum), but I renamed it to fix the previous naming mistake. Unfortunately this FDC unit is rare, so I still don't know whats the IC reference for the EPROM on the PCB. There is a photo of the CP-450 disk controller unit at: https://datassette.org/softwares/tandy-trs-color/cp-450-basic-disco-v-10 http://files.datassette.org/softwares/img/wp_20141212_22_08_26_pro.jpg

* 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.
* Move static data out of devices into the device types. This is a ↵ Vas Crabb2017-05-141-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
