2013-10-17arm: Add a 'clear PPI' method to gic_pl390Matt Evans
The underlying assumption that all PPIs must be edge-triggered is strained when the architected timers and VGIC interfaces make level-behaviour observable. For example, a virtual timer interrupt 'goes away' when the hypervisor is entered and the vtimer is disabled; this requires a PPI to be de-activated. The new method simply clears the interrupt pending state.
2012-10-25arm: Create a GIC base class and make the PL390 derive from itAndreas Sandberg
This patch moves the GIC interface to a separate base class and makes all interrupt devices use that base class instead of a pointer to the PL390 implementation. This allows us to have multiple GIC implementations. Future implementations will allow in-kernel GIC implementations when using hardware virtualization. --HG-- rename : src/dev/arm/gic.cc => src/dev/arm/gic_pl390.cc rename : src/dev/arm/gic.hh => src/dev/arm/gic_pl390.hh
