Factory elements can now pass additional parameters to device
constructors. This makes the design of interface objects like analog
callbacks easier.
The change also allowed to remove some "deep" calls into the core from
the MAME interface in netlist.h
plists.h was splitted into plists.h, pmulti_threading.h and
ptimed_queue.h. In addition removed plists.h from a number of files it
wasn't used in.
Certain minor adjustment needed to be made for cuda toolkit 10.1 and
10.2.
- Memory references in expressions no longer default to the console's visible CPU if no device name was specified, except when entered through the console itself. Expressions in view windows now use the context of the currently selected device instead.
- The pcatmem debug command and similar qt mouseover function now produce an error message if the initial address translation fails.
Related internal changes (nw)
- The debugger_cpu class no longer interprets memory accesses. The existing routines have been moved into symbol_table (which used to invoke them as callbacks), and reimplemented in most other places. Thecode duplication is a bit messy, but could be potentially improved in the future with new utility classes.
- The cheat engine no longer needs to hook into the debugger_cpu class or instantiate a dummy instance of it.
- The inclusion of debug/express.h within emu.h has been undone. Some debugging structures now need unique_ptr to wrap the resulting incomplete classes; hopefully the performance impact of this is negligible. Another direct consequence is that the breakpoint, watchpoint and registerpoint classes are no longer inside device_debug and have their own source file.
- The breakpoint list is now a std::multimap, using the addresses as keys to hopefully expedite lookup.
- The visible CPU pointer has been removed from the debugger_cpu class, being now considered a property of the console instead.
- Many minor bits of code have been simplified.
The last(?) two changes are:
- Add a template parameter to everything (theoretically the address
space width, in practice a level derived from it to keep as much
compatibility between widths as possible) so that the shift size
becomes a constant.
- Change the syntax of declaring and initializing the caches and
specifics so that they're embedded in the owner device. Solves
lifetime issues and also removes one indirection (looking up the base
dispatch pointer through the cache/specific pointer).
For reasons unknown to me compile optimizations do not behave for
template code. If the implementation is in separate compile units, the
code compiles and performs.
This needs more attention since for certain compilers there is a
considerable performance degregation. It looks like this is only
triggered if too many variants are declared in one cpp file and the
compiler stops inlining.
Thanks to Aaron Giles who made me think about a different approach.
This is a rewrite from scratch for rom devices. It uses a generic
template to implement rom devices which is used together with a
description struct to define a rom device. This leads to highly
efficient code since all information is available at compile time.
This is also a step forward to support tristate outputs. All rom devices
covered by this approach have tristate or open collector outputs and
thus all code changes to support tristate outputs can now be made
consistently in one file.
Code cleanup to better separate the following stages:
- parsing
- setup
- run
In addition preliminary native tristate support was added. Not yet
production ready, please don't use it.
The two sources act as voltage sources, though noise may also be
injected as conductivy or current noise.
SYS_NOISE_MT_U: Mersenne Twister uniform noise
SYS_NOISE_MT_N: Mersenne Twister normal noise
nld_sys_noise is templated:
using NETLIB_NAME(sys_noise_mt_u) =
NETLIB_NAME(sys_noise)<plib::mt19937_64,
plib::uniform_distribution_t>;
Thus the approach is scalable. The implementation is state save aware,
and thus reproducible results are guaranteed.
An example use case is provided as well, see examples/noise.cpp.
* new WORKING machines
Millennium M505 Arcade Neo Portable Spielkonsole (Family Sport 100-in-1) [TeamEurope]
* new NOT WORKING software list entries
tvgogo.xml : Baseball (US) [Sean Riddle, David Haywood]
tvgogo.xml : What-A-Mole (US) [Sean Riddle, David Haywood]
* added internal NAND dump to didj [Sean Riddle, Clawgrip]
The device can be found in nlm_other.cpp.
Removed nld_ne566.*
Added SYS_SW, SYS_SW2 and SYS_COMP. These are single switch,
alternating switch and a analog comparator with digital outputs.
Renamed RES_SWITCH to SYS_SW.
Added example ne566.cpp in netlist/examples.

MDT 60 Video Display Terminal [Bitsavers, AJR]
z29: Add skeleton for undumped keyboard; try (and fail) to make this work with the MDT 60 keyboard instead
z22: Separate driver (nw)
Changes:
- added known dump checksums of 1101 BIOS
- high-level emulation of GPIB disk devices
- partial implementation of DMA (currently ignores ACCRQ so devices must have zero latency in order for it to work)
- serial is now properly memory-mapped
- modem stub in order to make system properly ignore modem device
- it now boots without any patches and debug scripts
- merged #6597 (needed in order to make disk devices work)
Still not implemented:
- RTC/MACHINE_ID
- modem
- has problems with multiple disk devices working simultaneously (possibly BIOS bug because this BIOS had some problems with that on real device)
* Initial refactor of AVI/MNG movie recording, consolidation of copy and paste
code, hiding of AVI/MNG behind interfaces
* Extracted recording specific code out of src/emu/video.cpp and put into
src/emu/recording.cpp
* Took the opportunity to move slightly more logic out of video.cpp into
recording.cpp
* Bug fix
* Consolidated frame counting logic
Added a define NL_USE_ACADEMIC_SOLVERS and disabled it in the build.
This will not compile in solvers which are either illustrative or only
perform for large sparse matrices like GMRES.
Moved netlist between dasm and utils,expat,... link statements
This fixes the resolution of symbols in netlist code which may be used
in machine/netlist.cpp.
Change tested on ubuntu, windows and macosx.
This commit introduces precompiled static solver code. Due to
additional optimizations the compiler can use because the detail
calculation steps for the solution are known e.g. the kidniki netlist
sees a 100% speed increase.
In all environments (windows/*nix/osx) the source for the static
solver code can be created using
bash src/lib/netlist/nl_create_mame_solvers.sh
This will create src/lib/netlist/generated/static_solvers.cpp which is
compiled into the mame binary.
The script is just a temporary workaround. The intention is that nltool
whill be able to create this file with one call.
There are other improvements in this commit speeding up the processing
of timestep and dynamic calculations.
