machine configuration just as any other device, and the
standard CPU configuration is performed via the inline
configuration macros.
Change cpu_type from an enumeration into a pointer to the
CPU's get_info function, very similar to device behavior.
For now all CPUs are declared in cpuintrf.h, but
eventually they should be declared in the CPU's header
file, and the driver should #include that header.
Added function cpu_get_type() to return the CPU type.
Changed several cpu_* functions into macros that call
through to the equivalent device_* function.
The device system now maintains a parallel list of devices
based on type, for faster iteration through all devices
of a given type.
Cleaned up code that looped over CPUs via the machine->cpu
array to now loop using the type-based device list.
Removed start/stop/reset/nvram functions from the
device_config in favor of grabbing them as needed.
Cleaned up the generic interrupt_enable code to work with
CPU devices instead of numbers.
Mapped the devtag_* functions to device_* functions via
macros instead of parallel implementations.
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_*.
is either DEVICE_START_OK or DEVICE_START_MISSING_DEPENDENCY. The latter
should be returned by a device if there is another device it depends on
which hasn't been started yet. Added new flag in the device interface to
indicate whether a device has been started.
Changed laserdisc interface to explicitly specify the screen and sound
devices it should route to. Drivers no longer have to manually call
laserdisc_vsync(). Instead, the laserdisc code connects up to the routed
screen device and works based on that screen's VBLANK timing. Removed
all existing calls to laserdisc_vsync().
Changed laserdisc behavior so that it completes the previous video read
and initiates the next read at the end of VBLANK instead of the beginning.
This gives player logic time during VBLANK to alter the slider position
prior to fetching the next frame.
Added new laserdisc callback for vsync begin and changed the update
callback to be called at the end of VBLANK. Also added functions to set
the slider speed, advance the slider, and directly control the video/
audio squelch. In addition, there is a new status function to get the
slider position in general terms.
Added parameter to the VBLANK callbacks supported in emu/video.c. Updated
all callers to provide a callback value.
Fixed bug that would cause watchpoints to trigger if you had a memory
window open to the watchpoint address.
Further updates to the PR-8210 ROM simulation. Still not quite there but
the system is much better understood now. Added layout to the PR-8210
which displays the state of the front-panel LEDs.
Subject: another Machine -> machine cleanup
This cleans up most of the Machine stuff in src/emu/machine. There is
a bit left to clean up, but it's mostly stuck at some interfaces now.
Updated all call-through handlers appropriately. Renamed read8_handler to
read8_machine_func, replicating this pattern throughout.
Defined new set of memory handler functions which are similar but which
pass a const device_config * in place of the running_machine *. These are
called read8_device_func, etc. Added macros READ8_DEVICE_HANDLER() for
specifying functions of this type. Note that some plumbing still needs to
happen in memory.c before this will work.
This check-in should remove the need for the global Machine and in turn
"deprecat.h" for a lot of drivers, but that work has not been done. On
the flip side, some new accesses to the global Machine were added in the
emu/ files. These should be addressed over time, but are smaller in
number than the references in the driver.
The idea is to create extra work if a driver wants to use these and hopefully
gives an incentive to look for an alternate solution
- Added #include of deprecat.h that rely on these contructs
- Removed a bunch of unneccassary #include's from these files
