This effectively reverts b380514764cf857469bae61c11143a19f79a74c5 and
c24473ddff715ecec2e258a6eb38960cf8c8e98e, restoring the state at
598cd5227223c3b04ca31f0dbc1981256d9ea3ff.
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.

DMA/DRQ handling is simplified and hopefully more correct.
Tested working with mips, interpro and sun4.
* added 16 bit dma for ncr53c94
* added reset atn command
* refactored dma/drq code
* avoid a hang in disconnected selection
|
| |
|
|
|
|
|
| |
Several important fixes that help Sun4 (can now boot Solaris 2.3 from CD-ROM) and Jazz work better.
* Fix stupid virtual/override errors preventing ncr53c90a+ from working properly.
* Start DMA after arbitration/selection is completed for "select with..." commands.
* Trigger an interrupt on SCSI bus reset (if enabled).

S4-buffer, S4-cache, and S4-MMU, will eventually be split. [Ryan Holtz]
-sun4: Significant optimization, from 150% -> 330% unthrottled on an i7-5930K. [Ryan Holtz]

This gets sun4 slightly further along.

After reversing myself on this several times before, I hope I've now finally got it right.
* function/bus complete should proceed when the fifo is empty, to allow devices to send less data than indicated in the transfer count
* raise drq when tcounter = 0 (meaning 65536 bytes)

suddenly silenced
* streamline templates in addrmap.h
* get rid of overloads on read/write member names - this will become even more important in the near future
|
| |
|
|
|
|
|
| |
These changes make sun4 scsi work to some extent, and don't break interpro.
* ncr5390: dma support for disconnected state commands
* ncr5390: fix dma bug with tcounter=0 (meaning 65536)
* ncr5390: improve dma start and counter decrement
* sun4: fix dma control register writes
|

These changes work with InterPro, but haven't been tested on other machines. Despite this, I'm reasonably confident they are all correct according to the observed behaviour and the documentation.
* don't wait for REQ after initiator complete with NACK
* wait until fifo empty during dma out before command complete
* make sure drq is always cleared on bus/function complete
* reset happens immediately
* always clear TC0 when counter reloaded
* check valid commands separately for 5390 and 5390a
* handle 5390a initiator set attention command
* use logmacro for logging

Also, a lot more freedom happened, that's going to be more visible
soon.

* improved initiator transfer information logic
* split transfer count/counter
* added rudimentary 53c90a/53c94 support
* reworked initiator transfer information state machine: should now support all scsi phases
* improved handling of dma/non-dma commands
* added an undocumented hack to make InterPro work
* match updated 5390 device
* inherit memory map
* implemented interrupt status flag in status register for 53c90a, this is critical for InterPro

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.

* Make device_creator a variable template and get rid of the ampersands
* Remove screen.h and speaker.h from emu.h and add where necessary
* Centralise instantiations of screen and speaker finder templates
* Add/standardise #include guards in many hearers
* Remove many redundant #includes
* Order #includesr to help catch headers that can't be #included alone
(nw) This changes #include order to be prefix, unit header if applicable
then other stuff roughly in order from most dependent to least dependent
library. This helps catch headers that don't #include things that they
use.
