Colin Leroy-Mira	852b622c43	Apple2: Don't forcefully re-enable IRQ ... Avoid enabling IRQ after disabling them in driver code, remember previous state instead (in case user had them disabled already).	2024-12-09 19:01:00 +01:00
Colin Leroy-Mira	166a4b25f7	Apple2: implement sleep using MONWAIT ... Also publish detect_iigs(), set_iigs_speed() and get_iigs_speed(). Refactor to only store one ostype variable.	2024-01-18 16:17:10 +01:00
Oliver Schmidt	37107174c6	Added waitvsync() for the Enhanced Apple //e. ... The implementation is a bit tricky as it requires to take different code paths for the //e, the //c and the IIgs. Additionally the //c only provides a VBL IRQ flag supposed to be used by an IRQ handler to determine what triggered the IRQ. However, masking IRQs on the CPU, activating the VBL IRQ, clearing any pending VBL IRQs and then polling for the IRQ flag does the trick.	2020-06-18 21:44:57 +02:00
