* WARNING: This is a significant change. If you are risk-averse and Aaron Giles2008-11-061-6/+30
| | | | | | | | | | | | | | | | | | | | | working on something, hold off syncing. Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT, CPU_EXECUTE, along with macros for the name and for calling, in the spirit of the devintrf.h macros. More will come later. Changed init, reset, exit, and execute interfaces to be passed a const device_config * object. This is a fake object for the moment, but encapsulates the machine pointer and token. Eventually this will be a real device. Changed the CPU IRQ callbacks to a proper type, and added a device parameter to them. Updated all CPU cores to the new macros and parameters. Note that this changes the way we "pointer"-ify cores. I'll send an update shortly.

* Several miscellaneous changes: Aaron Giles2008-05-291-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | 1. In the MIPS core: - renamed struct mips3_config -> mips3_config - updated all drivers to the new names - removed MIPS3DRC_STRICT_COP0 flag, which is no longer used - a few minor cleanups 2. In the CPU interface: - added new 'intention' parameter to the translate callback to indicate read/write/fetch access, user/supervisor mode, and a flag for debugging - updated all call sites to pass an appropriate value - updated all CPU cores to the new prototype 3. In the UML: - added new opcode SETC to set the carry flag from a source bit - added new opcode BSWAP to swap bytes within a value - updated C, x86, x64 back-ends to support the new opcodes - updated disassembler to support the new opcodes 4. In the DRC frontend: - fixed bug in handling edge case with the PC near the 0 or ~0
* WIP check-in. Things work now, but I'm still working on the code. Aaron Giles2008-03-091-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | Converted address maps to tokens. Changed the address_map structure to house global map-wide information and hung a list of entries off of it corresponding to each address range. Introduced new functions address_map_alloc() and address_map_free() to build/destroy these structures. Updated all code as necessary. Fixed several instances of porttagtohandler*() in the address maps. Drivers should use AM_READ_PORT() macros instead. ADDRESS_MAP_EXTERN() now is required to specify the number of databits, just like ADDRESS_MAP_START. Removed ADDRESS_MAP_FLAGS() grossness. There are now three new macros which replace its former usage. ADDRESS_MAP_GLOBAL_MASK(mask) specifies a global address-space-wide mask on all addresses. Useful for cases where one or more address lines simply are not used at all. And ADDRESS_MAP_UNMAP_LOW/HIGH specifies the behavior of unmapped reads (do they come back as 0 or ~0). Changed internal memory mapping behavior to keep only a single address map and store the byte-adjusted values next in the address map entries rather than maintaining two separate maps. Many other small internal changes/cleanups.
* Normalized function pointer typedefs: they are now all Aaron Giles2008-03-031-40/+40
| | | | | | | | | | suffixed with _func. Did this throughout the core and drivers I was familiar with. Fixed gcc compiler error with recent render.c changes. gcc does not like explicit (int) casts on float or double functions. This is fracking annoying and stupid, but there you have it.
* Moves watchdog processing logic into its own module Zsolt Vasvari2008-03-021-0/+1

* Added CPUINFO_INT_CLOCK_MULTIPLIER to support CPU clock multipliers. Aaron Giles2008-01-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Updated all CPU cores to return a CPUINFO_INT_CLOCK_MULTIPLIER of 1. Changed the core to actually respect both CPUINFO_INT_CLOCK_MULTIPLIER and CPUINFO_INT_CLOCK_DIVIDER. Updated a number of drivers to use cpunum_get_clock() instead of Machine->drv->cpu[x].clock. ***** Raw input clock speeds should now be specified for all CPUs in the MACHINE_DRIVER. ***** Removed explicit divisors from all drivers using the following CPU types, which were already specifying non-1 values for CPUINFO_INT_CLOCK_DIVIDER: * COP4x0 * I8039/8048 families * M68(7)05, HD63705 * M6809E * PIC16C5X * TMS32010 * TMS340x0 In a few cases, it appears that the divisor was not being used, so I guessed in those cases whether or not the specified clock speed was raw.
* Copyright cleanup: Aaron Giles2008-01-061-1/+1
| | | | | | - removed years from copyright notices - removed redundant (c) from copyright notices - updated "the MAME Team" to be "Nicola Salmoria and the MAME Team"
* Initial checkin of MAME 0.121.mame0121 Aaron Giles2007-12-171-0/+516
