* hw/rtc/mc146818: Add missing dependency on ISA BusPhilippe Mathieu-Daudé2020-01-071-0/+1
| | | | | | | | | | | The MC146818 sits on an ISA bus. Since it can not be used without it, select ISA in the Kconfig.

| * mc146818rtc: fix timer interrupt reinjection againPaolo Bonzini2019-11-191-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 369b41359af46bded5799c9ef8be2b641d92e043 broke timer interrupt reinjection when there is no period change by the guest. In that case, old_period is 0, which ends up zeroing irq_coalesced (counter of reinjected interrupts). The consequence is Windows 7 is unable to synchronize time via NTP. Easily reproducible by playing a fullscreen video with cirrus and VNC. Fix by passing s->period when periodic_timer_update is called due to expiration of the timer. With this change, old_period == 0 only means that the periodic timer was off.

* | pl031: Expose RTCICR as proper WC registerAlexander Graf2019-11-191-5/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current PL031 RTCICR register implementation always clears the IRQ pending status on a register write, regardless of the value the guest writes. To justify that behavior, it references the ARM926EJ-S Development Chip Reference Manual (DDI0287B) and indicates that said document states that any write clears the internal IRQ state. It is indeed true that in section 11.1 this document says: "The interrupt is cleared by writing any data value to the interrupt clear register RTCICR". However, later in section 11.2.2 it contradicts itself by saying: "Writing 1 to bit 0 of RTCICR clears the RTCINTR flag." The latter statement matches the PL031 TRM (DDI0224C), which says: "Writing 1 to bit position 0 clears the corresponding interrupt. Writing 0 has no effect." Let's assume that the self-contradictory DDI0287B is in error, and follow the reference manual for the device itself, by making the register write-one-to-clear.
