This commit enables the QEMU icount mode for `mps2_an521`, in order to decouple the host clock from the emulated guest clock. This prevents guest timing instability from causing test failures when the host CPU load is very high. The icount `shift` value of 7 was empirically chosen to allow the tests to complete in both realistic and reasonable amount of time. The following are quick notes on the parameters used: * -icount shift=7: Execute one instruction every 128ns of virtual time * -icount align=off: Do not synchronise the host and guest clocks * -icount sleep=off: Advance virtual time without sleeping/waiting * -rtc clock=vm: Isolate the guest RTC time from the host Signed-off-by: Stephanos Ioannidis <root@stephanos.io> |
