[BUG] IPC timeout check mismatch between kernel and fw #8115
Description
Linux driver set ipc timeout duration to 500ms, but FW wait 5000ms in cpu_disable_core for SET_DX ipc message. This makes driver stop but fw is still waiting. And why we need 5000ms to disable core 1 ~ n ? Can we adopt 400 or 300 ms ?
void cpu_disable_core(int id) {
.....
uint64_t timeout = k_cycle_get_64() +
k_ms_to_cyc_ceil64(CONFIG_SECONDARY_CORE_DISABLING_TIMEOUT); // 5000ms
/* Waiting for secondary core to enter idle state */
while (arch_cpu_active(id) && (k_cycle_get_64() < timeout))
idelay(PLATFORM_DEFAULT_DELAY);
if (arch_cpu_active(id)) {
tr_err(&zephyr_tr, "core %d did not enter idle state", id);
return;
}
