- Removed device_timer, device_timer_id, et al in favor of direct callback members. (#9788)
Primarily, this removes device_t::device_timer, device_t::timer_set, device_t::synchronize, device_t::timer_expired, and device_timer_id. Use of device_timer often resulted in unnecessary trampolining in addition to switch/case overhead on a driver/device level, and additional logic to manage delegated vs. ID-based timers on a core level. In the worst cases, devices were performing a switch/case with only one valid case. device_scheduler::timer_set is marked deprecated as the only remaining direct uses are via the Lua engine and a few drivers that need refactoring anyway. The remaining uses occur via device_scheduler::synchronize. As a middle ground between the extremely short timer_alloc() and the extremely long machine().scheduler().timer_alloc(timer_expired_delegate(FUNC(widget_device::contoso_tick), this)), a helper function in device_t has been added which can be invoked with the following syntax: timer_alloc(FUNC(widget_device::contoso_tick), this) - Additional changes/cleanups performed along the way: - Converted to use logmacro: * src/devices/bus/ieee488/hp9895.cpp * src/devices/bus/ieee488/remote488.cpp * src/devices/bus/isa/hdc.cpp * src/devices/bus/isa/omti8621.cpp * src/devices/bus/isa/sc499.cpp * src/devices/bus/vip/vp550.cpp * src/devices/cpu/i86/i186.cpp * src/devices/cpu/lc8670/lc8670.cpp * src/devices/machine/68230pit.cpp * src/devices/machine/corvushd.cpp * src/devices/machine/ds1994.cpp * src/devices/machine/ticket.cpp * src/mame/audio/pinsnd88.cpp * src/mame/drivers/notetaker.cpp * src/mame/machine/asic65.cpp * src/mame/machine/rmnimbus.cpp * src/mame/machine/victor9k_fdc.cpp * src/mame/video/uv201.cpp -
