* emu/devcb.h: Eliminated the need to call resolve() on callbacks. (#11333) Vas Crabb2023-06-171-3/+2
| | | | | | | | | | | | Read callbacks now need a default return value supplied at construction. Replaced isnull() with isunset() which tells you if the callback wasn't configured rather than whether it isn't safe to call. Enabled validation of device callbacks (it seems it was disabled at some point, probably accidentally). Device callbacks and object finders now implement the same interface for resolution.

* Revert initialisation of device members in headers. Vas Crabb2022-04-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | This is problematic in several ways: * Initialising things at construction that aren't needed until after start slows down -romident, -validate, -listxml, etc. Slot cards can be a particular drain on -listxml and -validate as they're instantiated for every compatible slot. It's more pronounced for array members, too. * Splitting member initialisation between declaration in headers and constructors in source files means you have to look at two places to check for the initial value, and you always need to check the constructor even if an initialiser is present in the header because the constructor initaliser list takes precedence. (This isn't as much of an issue for driver classes because the constructor is most often inlined at declaration, so it isn't far from the member declarations.) * Initialisers in headers for frequently-used devices increases the frequency of recompiling dependent devices/drivers as they're exposed to any changes in initialisers. * Initialisers in frequently-used headers increase build times because there's more for the compiler to parse/cache. (This affects makedep.py as well for single-driver builds, but that's a single pass.) It's not a lot individually, but it adds up given the size of MAME, which keeps increasing. We've already had one contributor banned from GitHub actions for resource usage, we don't want to waste compiler time unnecessarily.

* Spring cleaning: Vas Crabb2019-11-011-1/+1
| | | | | | | | | | | | * Changed emu_fatalerror to use util::string_format semantics * Fixed some incorrectly marked up stuff in build scripts * Make internal layout compression type a scoped enum (only zlib is supported still, but at least the values aren't magic numbers now) * Fixed memory leaks in Xbox USB * There can only be one "perfect quantum" device - enforce that only the root machine can set it, as allowing subdevices to will cause weird issues with slot cards overiding it * Allow multiple devices to set maximum quantum and use the most restrictive one (it's maximum quantum, it would be minimum interleave) * Got rid of device_slot_card_interface as it wasn't providing value * Added a helper template to reduce certain kinds of boilerplate in slots/buses * Cleaned up some particularly bad slot code (plenty more of that to do), and made some slots more idiomatic
