* Touching all the candy again: [Alex Jackson] Alex W. Jackson2014-11-171-2/+1
| | | | | | | | | | | | | | | | Fixed an annoying inconsistency between memory_share and memory_region: the width() method of the former returned the width in bits (8, 16, 32 or 64) while the width() method of the latter returned the width in bytes (1, 2, 4 or 8). Now both classes have a bitwidth() method and a bytewidth() method. Updated all callers to use whichever one was more appropriate. Removed the implicit-cast-to-any-integer-pointer ability of memory_regions, which was rather unsafe (if you weren't careful with your * operators and casts it was easy to accidentally get a pointer to the memory_region object itself instead of to the data, with no warning from the compiler... or at least I kept doing it) Updated all devices and drivers that were accessing regions that way to use a region_ptr_finder when possible, and otherwise to call base() explicitly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove redundant machine items from address_space and device_t. Neither machine nor m_machine are directly accessible anymore. Instead a new getter machine() is available which returns a machine reference. So: space->machine->xxx ==> space->machine().xxx device->machine->yyy ==> device->machine().yyy Globally changed all running_machine pointers to running_machine references. Any function/method that takes a running_machine takes it as a required parameter (1 or 2 exceptions). Being consistent here gets rid of a lot of odd &machine or *machine, but it does mean a very large bulk change across the project. Structs which have a running_machine * now have that variable renamed to m_machine, and now have a shiny new machine() method that works like the space and device methods above. Since most of these are things that should eventually be devices anyway, consider this a step in that direction. 98% of the update was done with regex searches. The changes are architected such that the compiler will catch the remaining errors: // find things that use an embedded machine directly and replace // with a machine() getter call S: ->machine-> R: ->machine\(\)\. // do the same if via a reference S: \.machine-> R: \.machine\(\)\. // convert function parameters to running_machine & S: running_machine \*machine([^;]) R: running_machine \&machine\1 // replace machine-> with machine. S: machine-> R: machine\. // replace &machine() with machine() S: \&([()->a-z0-9_]+machine\(\)) R: \1 // sanity check: look for this used as a cast (running_machine &) // and change to this: *(running_machine *)

* C++-ified the sound and streams interfaces. Combined sound.c and streams.c Aaron Giles2011-01-271-6/+5
| | | | | | | | | | | | | | | | | | | into one file, and separated the speaker device into its own file. Generalized the concept of dynamically assigned inputs and re-wired the speaker to work this way, so it is now treated just like any other sound device. Added methods to the device_sound_interface for controlling output gain and mapping device inputs/outputs to stream inputs/outputs. Also made the sound_stream_update() method pure virtual, so all modern sound devices must use the new mechanism for stream updates. Primary changes outside of the core are: stream_update(stream) == stream->update() stream_create(device,...) == machine->sound().stream_alloc(*device,...) sound_global_enable(machine,enable) == machine->sound().system_enable(enable) Beyond this, the patterns are relatively obvious for the remaining calls.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Atari Ace] ---------- Forwarded message ---------- From: Atari Ace <atari_ace@frontier.com> Date: Tue, Aug 31, 2010 at 5:50 AM Subject: [patch] Despecialize legacy sound devices To: submit@mamedev.org Cc: atariace@hotmail.com Hi mamedev, While poking around in the MAME source code, I came across the odd type snes_sound_sound_device, which led me to the fact that legacy sound devices are named a bit differently than other legacy devices, probably a kludge intended to be changed later but forgotten. Anyhow, this patch fixes it. The first patch goes part way, changing all but the tag (which fixes the weird type issue). It also changes type names in the scsp and msm5232 cores to avoid a name collision if/when the second patch is applied. The second patch then touches a lot of files, mostly removing the SOUND_ prefix from type asserts, but it also needed to change the tags for the LASERDISC, S2636 and SPEAKER sound cores to avoid collisions with other devices with the same name. ~aa
* Split implementation for legacy devices into a separate macro. Updated all Aaron Giles2010-06-111-0/+2
| | | | | | | | devices to use this macro in their .c file. This greatly reduces the amount of work the linker has to do to combine all the instances, and reduces the final binary size when building with symbols. Unfortunately, in order to do it I had to switch back to macros from templates, but I can live with that for legacy devices.
* WARNING: There are likely to be regressions in both functionality and Aaron Giles2010-06-081-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance as a result of this change. Do not panic; report issues to the list in the short term and I will look into them. There are probably also some details I forgot to mention. Please ask questions if anything is not clear. NOTE: This is a major internal change to the way devices are handled in MAME. There is a small impact on drivers, but the bulk of the changes are to the devices themselves. Full documentation on the new device handling is in progress at http://mamedev.org/devwiki/index.php/MAME_Device_Basics Defined two new casting helpers: [Aaron Giles] downcast<type>(value) should be used for safe and efficient downcasting from a base class to a derived class. It wraps static_cast<> by adding an assert that a matching dynamic_cast<> returns the same result in debug builds. crosscast<type>(value) should be used for safe casting from one type to another in multiple inheritance scenarios. It compiles to a dynamic_cast<> plus an assert on the result. Since it does not optimize down to static_cast<>, you should prefer downcast<> over crosscast<> when you can. Redefined running_device to be a proper C++ class (now called device_t). Same for device_config (still called device_config). All devices and device_configs must now be derived from these base classes. This means each device type now has a pair of its own unique classes that describe the device. Drivers are encouraged to use the specific device types instead of the generic running_device or device_t classes. Drivers that have a state class defined in their header file are encouraged to use initializers off the constructor to locate devices. [Aaron Giles] Removed the following fields from the device and device configuration classes as they never were necessary or provided any use: device class, device family, source file, version, credits. [Aaron Giles] Added templatized variant of machine->device() which performs a downcast as part of the device fetch. Thus machine->device<timer_device>("timer") will locate a device named "timer", downcast it to a timer_device, and assert if the downcast fails. [Aaron Giles] Removed most publically accessible members of running_device/device_t in favor of inline accessor functions. The only remaining public member is machine. Thus all references to device->type are now device->type(), etc. [Aaron Giles] Created a number of device interface classes which are designed to be mix- ins for the device classes, providing specific extended functionality and information. There are standard interface classes for sound, execution, state, nvram, memory, and disassembly. Devices can opt into 0 or more of these classes. [Aaron Giles] Converted the classic CPU device to a standard device that uses the execution, state, memory, and disassembly interfaces. Used this new class (cpu_device) to implement the existing CPU device interface. In the future it will be possible to convert each CPU core to its own device type, but for now they are still all CPU devices with a cpu_type() that specifies exactly which kind of CPU. [Aaron Giles] Created a new header devlegcy.h which wraps the old device interface using some special template classes. To use these with an existing device, simply remove from the device header the DEVICE_GET_INFO() declaration and the #define mapping the ALL_CAPS name to the DEVICE_GET_INFO. In their place #include "devlegcy.h" and use the DECLARE_LEGACY_DEVICE() macro. In addition, there is a DECLARE_LEGACY_SOUND_DEVICE() macro for wrapping existing sound devices into new-style devices, and a DECLARE_LEGACY_NVRAM_DEVICE() for wrapping NVRAM devices. Also moved the token and inline_config members to the legacy device class, as these are not used in modern devices. [Aaron Giles] Converted the standard base devices (VIDEO_SCREEN, SPEAKER, and TIMER) from legacy devices to the new C++ style. Also renamed VIDEO_SCREEN to simply SCREEN. The various global functions that were previously used to access information or modify the state of these devices are now replaced by methods on the device classes. Specifically: video_screen_configure() == screen->configure() video_screen_set_visarea() == screen->set_visible_area() video_screen_update_partial() == screen->update_partial() video_screen_update_now() == screen->update_now() video_screen_get_vpos() == screen->vpos() video_screen_get_hpos() == screen->hpos() video_screen_get_vblank() == screen->vblank() video_screen_get_hblank() == screen->hblank() video_screen_get_width() == screen->width() video_screen_get_height() == screen->height() video_screen_get_visible_area() == screen->visible_area() video_screen_get_time_until_pos() == screen->time_until_pos() video_screen_get_time_until_vblank_start() == screen->time_until_vblank_start() video_screen_get_time_until_vblank_end() == screen->time_until_vblank_end() video_screen_get_time_until_update() == screen->time_until_update() video_screen_get_scan_period() == screen->scan_period() video_screen_get_frame_period() == screen->frame_period() video_screen_get_frame_number() == screen->frame_number() timer_device_adjust_oneshot() == timer->adjust() timer_device_adjust_periodic() == timer->adjust() timer_device_reset() == timer->reset() timer_device_enable() == timer->enable() timer_device_enabled() == timer->enabled() timer_device_get_param() == timer->param() timer_device_set_param() == timer->set_param() timer_device_get_ptr() == timer->get_ptr() timer_device_set_ptr() == timer->set_ptr() timer_device_timeelapsed() == timer->time_elapsed() timer_device_timeleft() == timer->time_left() timer_device_starttime() == timer->start_time() timer_device_firetime() == timer->fire_time() Updated all drivers that use the above functions to fetch the specific device type (timer_device or screen_device) and call the appropriate method. [Aaron Giles] Changed machine->primary_screen and the 'screen' parameter to VIDEO_UPDATE to specifically pass in a screen_device object. [Aaron Giles] Defined a new custom interface for the Z80 daisy chain. This interface behaves like the standard interfaces, and can be added to any device that implements the Z80 daisy chain behavior. Converted all existing Z80 daisy chain devices to new-style devices that inherit this interface. [Aaron Giles] Changed the way CPU state tables are built up. Previously, these were data structures defined by a CPU core which described all the registers and how to output them. This functionality is now part of the state interface and is implemented via the device_state_entry class. Updated all CPU cores which were using the old data structure to use the new form. The syntax is currently awkward, but will be cleaner for CPUs that are native new devices. [Aaron Giles] Converted the okim6295 and eeprom devices to the new model. These were necessary because they both require multiple interfaces to operate and it didn't make sense to create legacy device templates for these single cases. (okim6295 needs the sound interface and the memory interface, while eeprom requires both the nvram and memory interfaces). [Aaron Giles] Changed parameters in a few callback functions from pointers to references in situations where they are guaranteed to never be NULL. [Aaron Giles] Removed MDRV_CPU_FLAGS() which was only used for disabling a CPU. Changed it to MDRV_DEVICE_DISABLE() instead. Updated drivers. [Aaron Giles] Reorganized the token parsing for machine configurations. The core parsing code knows how to create/replace/remove devices, but all device token parsing is now handled in the device_config class, which in turn will make use of any interface classes or device-specific token handling for custom token processing. [Aaron Giles] Moved many validity checks out of validity.c and into the device interface classes. For example, address space validation is now part of the memory interface class. [Aaron Giles] Consolidated address space parameters (bus width, endianness, etc.) into a single address_space_config class. Updated all code that queried for address space parameters to use the new mechanism. [Aaron Giles]
* Disable many unused variables as identifed by cppcheck. [Oliver Stöneberg] Scott Stone2010-04-231-2/+2

* Made device->tag and devconfig->tag into private member variables (m_tag). Aaron Giles2010-03-081-1/+1
| | | | | | Added inline tag() function to return a const char * version. Updated callers to use this instead of directly accessing tag.cstr() which was awkward.
* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is now separate from runtime device state. I have larger plans for devices, so there is some temporary scaffolding to hold everything together, but this first step does separate things out. There is a new class 'running_device' which represents the state of a live device. A list of these running_devices sits in machine->devicelist and is created when a running_machine is instantiated. To access the configuration state, use device->baseconfig() which returns a reference to the configuration. The list of running_devices in machine->devicelist has a 1:1 correspondance with the list of device configurations in machine->config->devicelist, and most navigation options work equally on either (scanning by class, type, etc.) For the most part, drivers will now deal with running_device objects instead of const device_config objects. In fact, in order to do this patch, I did the following global search & replace: const device_config -> running_device device->static_config -> device->baseconfig().static_config device->inline_config -> device->baseconfig().inline_config and then fixed up the compiler errors that fell out. Some specifics: Removed device_get_info_* functions and replaced them with methods called get_config_*. Added methods for get_runtime_* to access runtime state from the running_device. DEVICE_GET_INFO callbacks are only passed a device_config *. This means they have no access to the token or runtime state at all. For most cases this is fine. Added new DEVICE_GET_RUNTIME_INFO callback that is passed the running_device for accessing data that is live at runtime. In the future this will go away to make room for a cleaner mechanism. Cleaned up the handoff of memory regions from the memory subsystem to the devices.
* Added casting operators to the region_info class so you can assign Aaron Giles2010-01-161-1/+1
| | | | | | | | | | | | | | | | a region to a generic type pointer and have it automatically convert. Also added a bytes() method which is safe if the region is NULL (useful for saying machine->region("foo")->bytes() and not crashing if foo doesn't exist). Changed the region field in the device_config to be a region_info *, and removed the regionbytes field. Updated all users of these fields to use the new casting operators and bytes() methods instead. Added subdevice and subregion methods to the device_config class, so you can easily query for devices and regions that are device-specific. The device prefix ("devicename:") is automatically prepended.
* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Created new central header "emu.h"; this should be included by pretty much any driver or device as the first include. This file in turn includes pretty much everything a driver or device will need, minus any other devices it references. Note that emu.h should *never* be included by another header file. - Updated all files in the core (src/emu) to use emu.h. - Removed a ton of redundant and poorly-tracked header includes from within other header files. - Temporarily changed driver.h to map to emu.h until we update files outside of the core. Added class wrapper around tagmap so it can be directly included and accessed within objects that need it. Updated all users to embed tagmap objects and changed them to call through the class. Added nicer functions for finding devices, ports, and regions in a machine: machine->device("tag") -- return the named device, or NULL machine->port("tag") -- return the named port, or NULL machine->region("tag"[, &length[, &flags]]) -- return the named region and optionally its length and flags Made the device tag an astring. This required touching a lot of code that printed the device to explicitly fetch the C-string from it. (Thank you gcc for flagging that issue!)
* The other larger patch adds missing static and const qualifiers, and Aaron Giles2009-06-081-1/+1
| | | | | | | | | fixes up some header files. In particular, I adjusted const char *DEVTEMPLATE_SOURCE = __FILE__ to const char DEVTEMPLATE_SOURCE[] = __FILE__ which makes it actually const and saves a little memory. [Atari Ace]
* Sound cores compile cleanly. Aaron Giles2009-03-121-1/+1

* Ok, this is The Big One. Aaron Giles2009-02-111-151/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
