[PATCH 3/3] Force ISR enable before scheduler start

[EYSSARTIER Kevin]

Classified as: {OPEN}

I don't know how to run the tests.
I observe that _Thread_Do_dispatch fails with INTERNAL_ERROR_BAD_THREAD_DISPATCH_ENVIRONMENT because RTEMS_SCORE_ROBUST_THREAD_DISPATCH is activated and the _ISR_Is_enabled returns false.

Indeed, the _CPU_Start_multitasking should be called properly, but the _RISCV_Start_multitasking function is only present when the RTEMS_SMP flag is activated. There is something that seems strange between the multitask and SMP functionalities in the riscv-context-switch.S file. A single core system should be capable of running a multitask system.

I agree that my solution is not good but moving _RISCV_Start_multitasking out of the '#ifdef RTEMS_SMP' barrier seems to bring many side effects.

Best regards,
