2019-02-14hw/mips_cpc: kick a VP when putting it into Run statewqMiodrag Dinic1-2/+15
While testing mttcg VP0 could get stuck in a loop waiting for other VPs to come up (which never actually happens). To fix this, kick VPs while they are being powered up by Cluster Power Controller in an async task which is triggered once the host thread is being spawned.

2016-07-12hw/mips_cpc: make VP correctly start from the reset vectorLeon Alrae1-3/+2
When VP enters the Run state it starts execution from the reset vector. Currently used CPU_INTERRUPT_WAKE does not do that if reset exception base has been modified. Therefore fix that by simply resetting given VP. Drop the usage of CPU_INTERRUPT_WAKE also in VP_STOP and instead raise the CPU_INTERRUPT_HALT to halt a VP.

2016-03-30hw/mips: add initial Cluster Power Controller supportLeon Alrae1-0/+177
Cluster Power Controller (CPC) is responsible for power management in multiprocessing system. It provides registers to control the power and the clock frequency of the individual elements in the system. This patch implements only three registers that are used to control the power state of each VP on a single core: * VP Run is a write-only register used to set each VP to the run state * VP Stop is a write-only register used to set each VP to the suspend state * VP Running is a read-only register indicating the run state of each VP Signed-off-by: Leon Alrae <leon.alrae@imgtec.com>
