* Correct a long-standing design flaw: device configuration state Aaron Giles2010-01-181-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-17/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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!)

* Hi mamedev, Aaron Giles2008-12-161-21/+14
| | | | | | | | | | | More deprecat.h cleanup in the core, notably changing the apis for poly_alloc. I also made cpu_get_index_slow fatalerror on failure since no one is checking the return value. deprecat.h -= 14, Machine -= ~55 ~aa

While this is a nice feature, each case introduces a then hard to remove deprecated Machine variable. One way to fix this would be to add machine to the parameter list for each verboselog call. Another way would be to change them to include the context call explicitly inside a typical logging macro (e.g. decocass.h). Not knowing which would be more acceptable to mamedev, I've included patches for both. ~aa (I chose to pass the machine to the verboselog function.)
* Here's the big one.... Aaron Giles2008-12-111-8/+1
| | | | | | | | | | | | | | | | | | | | | | | | Added new function cpuexec_describe_context(machine) which can be used in logerror() and other printf-style functions to return a description of the current CPU/PC given only the machine. Changed several dozen sites to use this instead of directly interrogating the activecpu. Removed all other uses of activecpu throughout the system. Removed activecpu from the machine structure to prevent future abuse. Removed cpu_push_context() and cpu_pop_context(), and all call sites. Voodoo devices now require a CPU to be defined in the configuration in order to know whom to steal cycles from or stall when FIFOs get full. Updated all voodoo users to specify one. CPD1869 devices now also require a CPU to be defined in the configuration, in order to know which CPU's registers to fetch. Updated all cdp1869 users to specify one. Many other small changes to make this all work.

Eventually most of these need to be converted to devices, but this change reduces the deprecation surface in the meantime. I also attached the script I used to do the initial changes to the drivers, which handled about 90% of the cases without further editing. ~aa
* Hi mamedev, Aaron Giles2008-12-081-13/+14
| | | | | | | | | | | | | | | | | | | | | | | This is a reworked/expanded version of the patch I sent yesterday. This one is split into three parts: 1. This introduces function macros for SAMPLES_START, CUSTOM_{START,STOP,RESET}, and ANTIC_RENDERER. 2. This introduces running_machine *machine throughout MAME. Principally it adds running_machine *machine = Machine to the top of functions, but in some static functions the parameter is added directly. Some similar changes in 99xxcore.h, v9938.c, v9938mod.c, galaxold.c, psx.c, taito_l.c are also made to eliminate Machine params. No global API is changed. 3. This changes the APIs introduced in the first part to pass device or space as appropriate. A few similar changes in some other global apis are made as well. The net result of this sequence of patches is to remove 40% of the Machine references and 27 deprecat.h includes. ~aa
* Changed save state system to accept machine parameters where Aaron Giles2008-12-051-13/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | appropriate, and to keep all global variables hanging off the machine structure. Once again, this means all state registration call sites have been touched: - state_save_register_global* now takes a machine parameter - state_save_register_item* now takes a machine parameter - added new state_save_register_device_item* which now uses the device name and tag to generate the base name Extended the fake sound devices to have more populated fields. Modified sound cores to use tags from the devices and simplified the start function. Renumbered CPU and sound get/set info constants to align with the device constants, and shared values where they were perfectly aligned. Set the type field in the fake device_configs for CPU and sound chips to a get_info stub which calls through to the CPU and sound specific get_info functions. This means the device_get_info() functions work for CPU and sound cores, even in their fake state. Changed device information getters from device_info() to device_get_info() to match the CPU and sound macros.

* Major cpuintrf changes: Aaron Giles2008-11-101-2/+3
| | | | | | | | | | | | | | | | | | | | | | * added a set of cpu_* calls which accept a CPU device object; these are now the preferred means of manipulating a CPU * removed the cpunum_* calls; added an array of cpu[] to the running_machine object; converted all existing cpunum_* calls to cpu_* calls, pulling the CPU device object from the new array in the running_machine * removed the activecpu_* calls; added an activecpu member to the running_machine object; converted all existing activecpu_* calls to cpu_* calls, pulling the active CPU device object from the running_machine * changed cpuintrf_push_context() to cpu_push_context(), taking a CPU object pointer; changed cpuintrf_pop_context() to cpu_pop_context(); eventually these will go away * many other similar changes moving toward a model where all CPU references are done by the CPU object and not by index
