* act/victor9k.cpp: Get audio working on Victor 9000 (victor9k) (#13549) donohoe002025-04-111-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 6522via: Don't generate a signal on PB7 when the timer 1 latch is programmed with 0. On the Victor 9000, the clock for the audio codec is generated by a via6522. PB7 is connected to the codec's clock input. Non-speech sounds (e.g. beeps, musical notes) are produced by outputting a cyclical waveform from the codec, with the pitch determined by the frequency of the codec clock. Software running on the Victor 9000 has been observed to attempt to silence the audio by writing 0 to the T1 timer latch (not by turning off continuous mode or PB7 output). With the emulated via6522, this resulted in a high-frequency clock signal being output on PB7, causing a high-pitched squeal whenever notes are not being played. From this observed behavior we could infer that the original 6522 HW does not output a signal on PB7 when the latch value is 0, and that the Victor 9000 software was relying on this behaviour to silence the audio output (one would have to assume that the real hardware didn't produce a squeal). * mc6852: fix various transmit-related issues which were preventing victor9k Audio output from working. The expected behavior of mc6852 is to write the data received in the FIFO register serially via tx_data_callback(). However, this was not implemented, and the only way data in the transmit FIFO could be removed and transmitted was by calling get_tx_byte(), and to then serially transmit the data by some external mechanism. Only m68sfdc.cpp calls get_tx_byte(), so it's hard to see how any other device using the mc6852 would have been able to transmit data. Software running on victor9k attempting to play audio would hang, since it would block waiting for the TX FIFO to empty. With these changes, Victor 9000 audio playback works as expected, with the data getting sent serially to the Audio codec. In order to avoid breaking m68sfdc, a new API call is added to allow data to be sent the "old" way. m68sfdc now calls set_tx_pull_mode(true), to get the previous behavior. As I understand it, other devices using mc6852 must be broken, and would need to be revisited. * victor9k: complete Audio support, adding a low-pass filter after the HC-55516 codec. Mark victor9k Audio as working.

* emu/devcb.h: Eliminated the need to call resolve() on callbacks. (#11333) Vas Crabb2023-06-171-7/+1
| | | | | | | | | | | | 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.

(#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) -
