[Qemu-devel] [PATCH 2/2] target-arm: Correct condition for taking VIRQ and VFIQ |
Date: |
Mon, 27 Oct 2014 12:58:07 +0000 |
The VIRQ and VFIQ exceptions are (as the comments say) only
taken if the CPU is in Non-secure state and the IMO/FMO bits
are set to enable virtualized interrupts. Correct the code
to actually implement this by using '||' rather than '&&'.
