2018-02-06	6027796 Browse files » TSPD: Require NS preemption along with EL3 exception handling ... At present, the build option TSP_NS_INTR_ASYNC_PREEMPT controls how Non-secure interrupt affects TSPs execution. When TSP is executing: 1. When TSP_NS_INTR_ASYNC_PREEMPT=0, Non-secure interrupts are received at the TSP's exception vector, and TSP voluntarily preempts itself. 2. When TSP_NS_INTR_ASYNC_PREEMPT=1, Non-secure interrupts causes a trap to EL3, which preempts TSP execution. When EL3 exception handling is in place (i.e., EL3_EXCEPTION_HANDLING=1), FIQs are always trapped to EL3. On a system with GICv3, pending NS interrupts while TSP is executing will be signalled as FIQ (which traps to EL3). This situation necessitates the same treatment applied to case (2) above. Therefore, when EL3 exception handling is in place, additionally require that TSP_NS_INTR_ASYNC_PREEMPT is set to one 1. Strictly speaking, this is not required on a system with GICv2, but the same model is uniformly followed regardless, for simplicity. Relevant documentation updated.

2018-02-06	1dd022c Browse files » TSPD: Explicitly allow NS preemption for Yielding SMCs ... When EL3 exception handling is in effect (i.e., EL3_EXCEPTION_HANDLING=1), Non-secure interrupts can't preempt Secure execution. However, for yielding SMCs, preemption by Non-secure interupts is intended. This patch therefore adds a call to ehf_allow_ns_preemption() before dispatching a Yielding SMC to TSP.

Currently, Trusty OS/LK implemented FPU context switch in internal thread switch but does not implement the proper mechanism for world switch.
