There was a problem hiding this comment.
In current master branch, cpu_state_t has 3 states.
Do we have plan to reduce it to two states? If not we need to update cpu_states to 3 states array.
typedef enum {
CPU_RUNNING = 0, /* CPU is in task scheduer or boot from reset */
CPU_HOTPLUG = 1, /* CPU is offline */
CPU_WAKE_FROM_SLEEP = 2, /* CPU just wake from sleep but not in task scheduler */
} cpu_state_t;When hotplug manager is implemented, we have to check here too.

Hello @mukku-suneel |
Add character driver for Secondary CPUs management operations through /dev/cpuX device nodes. Provides ioctl interface for CPU enable/disable and state query operations. This driver enables userspace applications and test utilities to control CPU states and perform cpu on/off operations through standard interface.
…esting Add cputest application with shell commands for testing CPU driver functionality. Provides commands to enable/disable secondary CPUs and check CPU status through device interface. Shell commands added: - cpuctrl on <cpu_id>: Power on specified CPU - cpuctrl off <cpu_id>: Power off specified CPU - cpuctrl status: Show status of all Secondary CPUs - cpuctrl help : Show the help message Test Results: TASH>> TASH>> TASH>>cpuctrl status TASH>>cpu state for cpu1: 0 (running) TASH>> TASH>> TASH>> TASH>>smp TASH>> Main[0]: Running on CPU0 Main[0]: Initializing barrier Running SMP test with AMP configuration Thread[1]: Started Thread[1]: Running on CPU0 Main[0]: Thread 1 created Thread[2]: Started Thread[2]: Running on CPU1 Main[0]: Thread 2 created Thread[3]: Started Thread[3]: Running on CPU0 Main[0]: Thread 3 created Thread[4]: Started Thread[4]: Running on CPU1 Main[0]: Thread 4 created Thread[5]: Started Thread[5]: Running on CPU0 Main[0]: Thread 5 created Thread[6]: Started Thread[6]: Running on CPU1 Main[0]: Thread 6 created Thread[7]: Started Thread[7]: Running on CPU0 Main[0]: Thread 7 created Thread[8]: Started Thread[8]: Running on CPU1 Main[0]: Thread 8 created Thread[2]: Calling pthread_barrier_wait() Thread[1]: Calling pthread_barrier_wait() Thread[4]: Calling pthread_barrier_wait() Thread[3]: Calling pthread_barrier_wait() Thread[5]: Calling pthread_barrier_wait() Thread[6]: Calling pthread_barrier_wait() Thread[7]: Calling pthread_barrier_wait() Thread[8]: Calling pthread_barrier_wait() Thread[8]: Back with ret=PTHREAD_BARRIER_SERIAL_THREAD (I AM SPECIAL) Thread[1]: Back with ret=0 (I am not special) Thread[3]: Back with ret=0 (I am not special) Thread[5]: Back with ret=0 (I am not special) Thread[7]: Back with ret=0 (I am not special) Thread[2]: Back with ret=0 (I am not special) Thread[4]: Back with ret=0 (I am not special) Thread[6]: Back with ret=0 (I am not special) Thread[8]: Done Thread[2]: Done Thread[4]: Done Thread[6]: Done Thread[1]: Done Thread[3]: Done Thread[5]: Done Main[0]: Thread 1 completed with result=0 Thread[7]: Done Main[0]: Thread 2 completed with result=0 Main[0]: Thread 3 completed with result=0 Main[0]: Thread 4 completed with result=0 Main[0]: Thread 5 completed with result=0 Main[0]: Thread 6 completed with result=0 Main[0]: Thread 7 completed with result=0 Main[0]: Thread 8 completed with result=0 TASH>> TASH>> TASH>> TASH>> TASH>>cpuctrl off 1 TASH>>powering down cpu1!
