Hi,

I have test do_switch_normal interface, it seems that can't make system reboot (4.1.15 Kernel). is config issue?

Hi ,

See here , please!

/* mach-imx6q.c */

DT_MACHINE_START(IMX6Q, "Freescale i.MX6 Quad/DualLite (Device Tree)")
   /*
   * i.MX6Q/DL maps system memory at 0x10000000 (offset 256MiB), and
   * GPU has a limit on physical address that it accesses, which must
   * be below 2GiB.
   */
   .dma_zone_size   = (SZ_2G - SZ_256M),
   .smp       = smp_ops(imx_smp_ops),
   .map_io       = imx6q_map_io,
   .init_irq   = imx6q_init_irq,
   .init_time   = imx6q_timer_init,
   .init_machine   = imx6q_init_machine,
   .init_late      = imx6q_init_late,
   .dt_compat   = imx6q_dt_compat,
   .restart   = mxc_restart,
MACHINE_END

and mxc_restart() is in arch/arm/kernel/system.c

Have a nice day!

Hi Sun,

I know that.

4.1.15 bsp never use mxc_restart.

1 DT_MACHINE_START(IMX6Q, "Freescale i.MX6 Quad/DualLite (Device Tree)")
2     .smp        = smp_ops(imx_smp_ops),
3     .map_io     = imx6q_map_io,
4     .init_irq   = imx6q_init_irq,
5     .init_machine   = imx6q_init_machine,
6     .init_late      = imx6q_init_late,
7     .dt_compat = imx6q_dt_compat,
8     .reserve        = imx6q_reserve,
9 MACHINE_END
