This effectively changes riscv_cpu_update_mip from edge to level. i.e. cpu_interrupt or cpu_reset_interrupt are called regardless of the current interrupt level. Fixes WFI doesn't return when a IPI is issued: - https://github.com/riscv/riscv-qemu/issues/132 To test: 1) Apply RISC-V Linux CPU hotplug patch: - http://lists.infradead.org/pipermail/linux-riscv/2018-May/000603.html 2) Enable CONFIG_CPU_HOTPLUG in linux .config 3) Try to offline and online cpus: echo 1 > /sys/devices/system/cpu/cpu2/online echo 0 > /sys/devices/system/cpu/cpu2/online echo 1 > /sys/devices/system/cpu/cpu2/online Reported-by: Atish Patra <atishp04@gmail.com> Cc: Atish Patra <atishp04@gmail.com> Cc: Alistair Francis <Alistair.Francis@wdc.com> Signed-off-by: Michael Clark <mjc@sifive.com> Signed-off-by: Alistair Francis <alistair.francis@wdc.com> Signed-off-by: Palmer Dabbelt <palmer@sifive.com> |
