related APIs now take a device pointer instead of an index.
All functions that take a CPU device are prefixed with cpu_*
All functions that are globally related to cpu execution
are prefixed with cpuexec_*. Below is a list of some of the
mappings:
cpu_boost_interleave -> cpuexec_boost_interleave
cpunum_suspend -> cpu_suspend
cpunum_resume -> cpu_resume
cpunum_is_suspended -> cpu_is_suspended
cpunum_get_clock -> cpu_get_clock
cpunum_set_clock -> cpu_set_clock
cpunum_get_clockscale -> cpu_get_clockscale
cpunum_set_clockscale -> cpu_set_clockscale
cpunum_get_localtime -> cpu_get_local_time
cpunum_gettotalcycles -> cpu_get_total_cycles
activecpu_eat_cycles -> cpu_eat_cycles
activecpu_adjust_icount -> cpu_adjust_icount
cpu_trigger -> cpuexec_trigger
cpu_triggertime -> cpuexec_triggertime
cpunum_set_input_line -> cpu_set_input_line
cpunum_set_irq_callback -> cpu_set_irq_callback
In addition, a number of functions retain the same name but
now require a specific CPU parameter to be passed in:
cpu_yield
cpu_spin
cpu_spinuntil_time
cpu_spinuntil_int
cpu_spinuntil_trigger
cpu_triggerint
Merged cpuint.c into cpuexec.c. One side-effect of this
change is that driver reset callbacks are called AFTER the
CPUs and devices are reset. This means that if you make
changes to the CPU state and expect the reset vectors to
recognize the changes in your reset routine, you will need
to manually reset the CPU after making the change (since it
has already been reset).
Added a number of inline helper functions to cpuintrf.h for
managing addresses
Removed cpu_gettotalcpu(). This information is rarely needed
outside of the core and can be obtained by looking at the
machine->cpu[] array.
Changed CPU interrupt acknowledge callbacks to pass a CPU
device instead of machine/cpunum pair.
Changed VBLANK and periodic timer callbacks to pass a CPU
device instead of machine/cpunum pair.
Renamed all information getters from cpu_* to cpu_get_* and
from cputype_* to cputype_get_*.
working on something, hold off syncing.
Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT,
CPU_EXECUTE, along with macros for the name and for calling, in the
spirit of the devintrf.h macros. More will come later.
Changed init, reset, exit, and execute interfaces to be passed a
const device_config * object. This is a fake object for the moment,
but encapsulates the machine pointer and token. Eventually this will
be a real device.
Changed the CPU IRQ callbacks to a proper type, and added a device
parameter to them.
Updated all CPU cores to the new macros and parameters.
Note that this changes the way we "pointer"-ify cores. I'll send an
update shortly.
adds/removes entries in header files, and fixes a few potential
multisession issues by explicitly adding initializers. asic65.c has
significant changes to accomodate using a struct instead of 16
variables, otherwise the changes in this patch are modest and obvious.

macro from the source code. All MAME builds now include
the debugger, and it is enabled/disabled exclusively by
the runtime command-line/ini settings. This is a minor
speed hit for now, but will be further optimized going
forward.
Changed the 'd' suffix in the makefile to apply to DEBUG
builds (versus DEBUGGER builds as it did before).
Changed machine->debug_mode to machine->debug_flags.
These flags now indicate several things, such as whether
debugging is enabled, whether CPU cores should call the
debugger on each instruction, and whether there are live
watchpoints on each address space.
Redesigned a significant portion of debugcpu.c around
the concept of maintaining these flags globally and a
similar, more complete set of flags internally for each
CPU. All previous functionality should work as designed
but should be more robust and faster to work with.
Added new debugger hooks for starting/stopping CPU
execution. This allows the debugger to decide whether
or not a given CPU needs to call the debugger on each
instruction during the coming timeslice.
Added new debugger hook for reporting exceptions.
Proper exception breakpoints are not yet implemented.
Added new module debugger.c which is where global
debugger functions live.
1. In the MIPS core:
- renamed struct mips3_config -> mips3_config
- updated all drivers to the new names
- removed MIPS3DRC_STRICT_COP0 flag, which is no longer used
- a few minor cleanups
2. In the CPU interface:
- added new 'intention' parameter to the translate callback to
indicate read/write/fetch access, user/supervisor mode, and
a flag for debugging
- updated all call sites to pass an appropriate value
- updated all CPU cores to the new prototype
3. In the UML:
- added new opcode SETC to set the carry flag from a source bit
- added new opcode BSWAP to swap bytes within a value
- updated C, x86, x64 back-ends to support the new opcodes
- updated disassembler to support the new opcodes
4. In the DRC frontend:
- fixed bug in handling edge case with the PC near the 0 or ~0
* Fixed front-end so that virtual no-op instructions are still targeted
as branch targets.
* Fixed front-end to mark the beginning of each sequence as needing TLB
validation, since any sequence can be jumped to from anywhere.
* Redid the MIPS3 TLB implementation. Fixed the exception vector and
type handling. Changed the bitfields to directly map from the MIPS TLB
format. Added distinction between TLB fill and TLB valid/modified
exceptions.
* Added separate modes for user, supervisor, and kernel modes. Each mode
does proper verification of addresses now and generates address errors
for invalid accesses.
* Fixed several bugs in the TLB implementation; not everything works
yet but it's a lot closer.
* Made COP0 access checking mandatory in non-kernel modes.
* Fixed several crashes when recompiling virtual no-ops.
* Fixed TLB bug where entries for virtual address 0 were present by
default.
* Fixed bug in the map variable implementation that would sometimes
result in incorrectly recovered values.
trace through in a debug build, yet should operate the same as before.
Created a complete set of functions for all databus sizes (8,16,32,64) and
all endiannesses. A few functions are redundant, but it is now very clear
which functions to use in which scenarios. It is also now possible to rely
on being able to access values of 8, 16, 32 or 64 bits via the built-in
accessors without fear of crashing.
Updated all cores using 8-bit handlers to explicitly call the 8-bit handlers
with the appropriate endianness.
Fixed a few games which were calling n-bit handlers directly to use the
generic forms. In the future, this is all the access drivers will have.
Converted address maps to tokens. Changed the address_map structure
to house global map-wide information and hung a list of entries off
of it corresponding to each address range. Introduced new functions
address_map_alloc() and address_map_free() to build/destroy these
structures. Updated all code as necessary.
Fixed several instances of porttagtohandler*() in the address maps.
Drivers should use AM_READ_PORT() macros instead.
ADDRESS_MAP_EXTERN() now is required to specify the number of
databits, just like ADDRESS_MAP_START.
Removed ADDRESS_MAP_FLAGS() grossness. There are now three new macros
which replace its former usage. ADDRESS_MAP_GLOBAL_MASK(mask)
specifies a global address-space-wide mask on all addresses. Useful
for cases where one or more address lines simply are not used at
all. And ADDRESS_MAP_UNMAP_LOW/HIGH specifies the behavior of
unmapped reads (do they come back as 0 or ~0).
Changed internal memory mapping behavior to keep only a single
address map and store the byte-adjusted values next in the address
map entries rather than maintaining two separate maps. Many other
small internal changes/cleanups.
a new compile-time define (ENABLE_DEBUGGER). This means that MAME_DEBUG no longer means
"enable debugger", it simply enables debugging features such as assertions and debug code
in drivers.
Also removed the various levels of opbase protection in memory.h and always just turned
on full bounds checking.
Fixed build break due to missing ampoker.lay -> ampoker2.lay renaming.
