| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and paths consistently for devices, I/O ports, memory regions, memory banks, and memory shares. [Aaron Giles] NOTE: there are likely regressions lurking here, mostly due to devices not being properly found. I have temporarily added more logging to -verbose to help understand what's going on. Please let me know ASAP if anything that is being actively worked on got broken. As before, the driver device is the root device and all other devices are owned by it. Previously all devices were kept in a single master list, and the hierarchy was purely logical. With this change, each device owns its own list of subdevices, and the hierarchy is explicitly manifest. This means when a device is removed, all of its subdevices are automatically removed as well. A side effect of this is that walking the device list is no longer simple. To address this, a new set of iterator classes is provided, which walks the device tree in a depth first manner. There is a general device_iterator class for walking all devices, plus templates for a device_type_iterator and a device_interface_iterator which are used to build iterators for identifying only devices of a given type or with a given interface. Typedefs for commonly-used cases (e.g., screen_device_iterator, memory_interface_iterator) are provided. Iterators can also provide counts, and can perform indexed lookups. All device name lookups are now done relative to another device. The maching_config and running_machine classes now have a root_device() method to get the root of the hierarchy. The existing machine->device("name") is now equivalent to machine->root_device().subdevice("name"). A proper and normalized device path structure is now supported. Device names that start with a colon are treated as absolute paths from the root device. Device names can also use a caret (^) to refer to the owning device. Querying the device's tag() returns the device's full path from the root. A new method basetag() returns just the final tag. The new pathing system is built on top of the device_t::subtag() method, so anyone using that will automatically support the new pathing rules. Each device has its own internal map to cache successful lookups so that subsequent lookups should be very fast. Updated every place I could find that referenced devices, memory regions, I/O ports, memory banks and memory shares to leverage subtag/subdevice (or siblingtag/siblingdevice which are built on top). Removed the device_list class, as it doesn't apply any more. Moved some of its methods into running_machine instead. Simplified the device callback system since the new pathing can describe all of the special-case devices that were previously handled manually. Changed the core output function callbacks to be delegates. Completely rewrote the validity checking mechanism. The validity checker is now a proper C++ class, and temporarily takes over the error and warning outputs. All errors and warnings are collected during a session, and then output in a consistent manner, with an explicit driver and source file listed for each one, as well as additional device and/or I/O port contexts where appropriate. Validity checkers should no longer explicitly output this information, just the error, assuming that the context is provided. Rewrote the software_list_device as a modern device, getting rid of the software_list_config abstraction and simplifying things. Changed the way FLAC compiles so that it works like other external libraries, and also compiles successfully for MSVC builds.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 *)

* First round of an attempted cleanup of header files in the system. Aaron Giles2010-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - 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!)

I changed the code back to how it behaved originally, using an existing machine on the chip struct to eliminate the one troublesome Machine reference. ~aa -- From: Atari Ace [mailto:atari_ace@verizon.net] Sent: Thursday, December 18, 2008 2:54 PM To: submit@mamedev.org Cc: atariace@hotmail.com Subject: [patch] Make Machine static! Hi mamedev, This large patch completes the removal of the use of Machine throughout MAME. It does so primarily by adding machine, device or space to various apis and modifying the callers, but for some remaining cases it adds a new api, mame_get_running_machine(), which will be called instead. There are only 14 uses of this api currently, and that number should drop over time. There are a few changes of note: 1. 6821pia.c. I attached machine to the 'device' structure. I'm working on converting this to a proper device, but that change isn't ready. 2. fddebug.c. I added a proper header so that the apis won't get accidentally converted to static again. 3. scsi.c. I added a machine to SCSIInstance. 4. system16.c. I modified sys16_patch_code to take an array of patches. 4. custom.h. I added the owning sound device to the reset/stop routines as well as the token. Note that passing only the device would require exposing the internals of custom_sound, as the token passed is not the device token, but the token returned from the CUSTOM_START routine. Better ideas here are welcome. 4. ppc2c0x.c. To avoid changing more interfaces, the init routine saves the videorom location rather than looks it up each time. I tried to choose what I felt was the natural parameter for an api, rather than always pass machine, but in some cases I used machine to limit the number of additional changes. Some additional cleanup here is probably warranted, I'll look into that later once I'm recovered from this two-week project. ~aa
* Hi mamedev, Aaron Giles2008-12-081-2/+3
| | | | | | | | | | | | | | | | | | | | | | | 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 Giles2008-12-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* Added "tag" parameter to state_save_register_item_* calls. Removed Aaron Giles2008-11-171-5/+2
| | | | | | state_save_combine_module_and_tag() function in favor of passing the tag when registering. Revisited all save state item registrations and changed them to use the tag where appropriate.

* Disks opened by the romload module are no longer identified by index. Aaron Giles2008-08-011-6/+12
| | | | | | | | | | | | | | | | | Instead, they are identified by the region they were loaded in. This generally means one disk per region. get_disk_handle() now takes a region name in place of an index. Updated all callers to do this. The SCSI modules in particular posed a challenge to make this work, so watch out for potential bugs there. Changed the IDE interfaces to default to choosing the region with the same tag as the device for its master disk (assuming no slave). Added support for specifying explicit master/slave disk regions as part of the configuration, though slave disks are still not supported yet. Change the laserdisc interface to no longer require a disk number or a custom sound device. Both are now assumed to be tagged the same as the laserdisc device. Updated all drivers accordingly.
* (From Atari Ace) Aaron Giles2007-12-241-0/+1
| | | | | | | | | | This small patch makes some minor "code quality" improvements to MAME. First off, some remaing static/const qualifier missed cases were addressed. Secondly, a few cases of missing #include "foo.h" were added. Thirdly, a few global names were modified to make them less generic/more consistent (voodoo.c, vrender0.c, lethal.c, rungun.c, zac2650.c). Fourthly, some dead/useless code was removed (i8051.c,model1.c,romcmp.c).
