This update changes the way we handle memory allocation. Rather
than allocating in terms of bytes, allocations are now done in
terms of objects. This is done via new set of macros that replace
the malloc_or_die() macro:
alloc_or_die(t) - allocate memory for an object of type 't'
alloc_array_or_die(t,c) - allocate memory for an array of 'c' objects of type 't'
alloc_clear_or_die(t) - same as alloc_or_die but memset's the memory to 0
alloc_array_clear_or_die(t,c) - same as alloc_array_or_die but memset's the memory to 0
All original callers of malloc_or_die have been updated to call these
new macros. If you just need an array of bytes, you can use
alloc_array_or_die(UINT8, numbytes).
Made a similar change to the auto_* allocation macros. In addition,
added 'machine' as a required parameter to the auto-allocation macros,
as the resource pools will eventually be owned by the machine object.
The new macros are:
auto_alloc(m,t) - allocate memory for an object of type 't'
auto_alloc_array(m,t,c) - allocate memory for an array of 'c' objects of type 't'
auto_alloc_clear(m,t) - allocate and memset
auto_alloc_array_clear(m,t,c) - allocate and memset
All original calls or auto_malloc have been updated to use the new
macros. In addition, auto_realloc(), auto_strdup(), auto_astring_alloc(),
and auto_bitmap_alloc() have been updated to take a machine parameter.
Changed validity check allocations to not rely on auto_alloc* anymore
because they are not done in the context of a machine.
One final change that is included is the removal of SMH_BANKn macros.
Just use SMH_BANK(n) instead, which is what the previous macros mapped
to anyhow.
Please note: regression testing is in progress, but the first round
of glaring regressions have already been taken care of. That said,
there is likely to be a host of regressions as a result of this
change.
Also note: There are still a few rough edges in the interfaces. I
will try to clean them up systematically once the basic system is
working.
All sound chips are now proper devices.
Merged the sound chip interface into the device interface,
removing any differences (such as the whole ALIASing concept).
Modified every sound chip in the following ways:
* updated to match the device interface
* reduced read/write handlers down to the minimal number
* added the use of get_safe_token() for ensuring correctness
* other minor cleanup
Removed the custom sound device. The additional work to just make
custom sound cases into full devices is minimal, so I just converted
them all over to be actual devices.
Vastly simplified the sound interfaces, removing the ghastly
sndti_* business and moving everyone over to using tags for
sound identity. sndintrf, like cpuintrf, is now just a header
file with no implementation.
Modified each and every driver that references a sound chip:
* all memory maps explicitly reference the targeted device via
AM_DEVREAD/AM_DEVWRITE/AM_DEVREADWRITE
* 16-bit and 32-bit accesses to 8-bit chips no longer use
trampoline functions but instead use the 8-bit AM_DEVREAD/WRITE
macros
* all references to sound chips are now done via tags
* note that these changes are brute force, not optimal; in many
cases drivers should grab pointers to devices in MACHINE_START
and stash them away
- added running_machine to internal structure, removed as explicit parameter
- added new function rom_file_size() to compute the size of a ROM
- removed rom_first_chunk() and rom_next_chunk() which are no longer needed
- changed progress display to be based on size of ROMs loaded, not number
- changed temporary load buffer to be dynamically allocated
- fixed reload logic to handle skipped BIOSes
Also changed rand_memory() to use a fixed seed for consistent behavior.
of a given driver, meaning those drivers that come from the same source
file, along with their parent names if they are clones. If a wildcard
name is specified for the driver, then the first driver in a given
source file will trigger a list of his brothers, and any other drivers
in the same source file which match the wildcard will be flagged.
cpu_get_info_* -> device_get_info_*
cpu_set_info_* -> device_set_info_*
cpu_reset -> device_reset
Removed the cputype_get_* macros as they are not necessary.
Removed cpuintrf_init() which is no longer necessary.
struct CustomSound_interface to custom_sound_interface
struct Samplesinterface to samples_interface
struct SN76477interface to SN76477_interface
struct AY8910interface to AY8910_interface
I applied the same fix to verifyroms. Now a status message is printed for every sample/ROM set regardless if an individual or all the sets are audited.
constructors to tokenized lists. For the most part
this is a non-invasive change, except for those drivers
using MDRV_WATCHDOG_TIME_INIT. In order to allow for
tokenization of attotimes, a set of new macros is
provided called UINT64_ATTOTIME_IN_x() which follows the
same pattern as ATTOTIME_IN_x() but packs the attotime
down into a single 64-bit value for easier tokenization.
Separated MDRV_DEVICE_CONFIG_DATA into 32-bit and 64-bit
versions. Added floating-point versions with configurable
resolutions.
Fixed several errors in the machine drivers which were
caught by the additional checks now done in the machine
config detokenization code.
Converted speakers into devices. Machine->config no
longer houses an array of speakers; instead they are
iterated through using the new macros (defined in sound.h)
speaker_output_first() and speaker_output_next(). Updated
all relevant code to do this.
Improved game info display with multiple screens. Fixed
bug which caused all screens to display equally.
Added typedefs for all the machine config callback
functions at the top of driver.h.
