* Introduces Schedule_context * Use fast-interrupts or normal interrupts * Add mode-transition between secure/non-secure world * Limit system resources for Genode apps due to non-secure world This commit implements the newly introduced Vm session interface to be used on top of TrustZone capable Armv7 CPUs. Therefore a new Schedule_context is introduced in the kernel. Threads and Vms are both Schedule_contexts used by the scheduler. In contrast to a thread a vm uses a different assembler mode switch to the non-secure, virtual world, as well as another exception is used, when the non-secure world is left. For both worlds to co-exist the interrupt-controller needs to be configured, so that the secure (Genode) world uses fast-interrupts only, and the non-secure world only legacy interrupts. The only TrustZone capable platform the base-hw kernel works on top of is the CoreTile Express 9x4 for the Versatile Express motherboard. For a virtual machine working properly on top some platform resources must be reserved. Therefore there exist two flavours of this platform now, one with the 'trustzone' spec-variable enabled, and one without. If 'trustzone' is specified most platform resources (DDR-RAM, and most IRQs) are reserved for the Vm and not available to the secure Genode world. |
