x96 mini should use p281/tx3mini dtb I think

 

@balbes150 I used all the s905w, s905x and khadas dtbs but still no poweroff.

 

Running Linux aml 5.1.0-rc1-aml-s905 #5.82 SMP PREEMPT Sat Apr 27 22:41:29 MSK 2019 aarch64 GNU/Linux

 

Is it working with other hardware?

 

I tried tracing the differences in the kernel and it seems like the stop call is different in the mainline kernel vs khadas-3.14. I haven't had a chance to build a kernel to test.

 

smp.c : ipi_cpu_stop

...

__asm__ volatile("dsb sy");

__asm__ volatile("isb");

while (1)

__asm__ volatile("wfi");

 

mainline

smp.c:

static void ipi_cpu_stop(unsigned int cpu)

{

set_cpu_online(cpu, false);

local_daif_mask();

sdei_mask_local_cpu();

while (1)

cpu_relax();

}

@balbes150 Is there any way to make the system poweroff? With my x96 mini on the 5.1 rc, both reboot and poweroff, reboot the system. With 3.14, poweroff would prevent a reboot and show a red light on the front of the box:

 

root@aml:~# sudo poweroff
[   53.748046] reboot: Power down
bl31 reboot reason: 0x8
bl31 reboot reason: 0x8
system cmd  0.

 

With 3.14 I would see reason 0x108
