Joseph,
In next-20121217, I see:
void __ref tegra_cpu_die(unsigned int cpu)
{
cpu = cpu_logical_map(cpu);
/* Flush the L1 data cache. */
flush_cache_all();
/* Shut down the current CPU. */
tegra_hotplug_shutdown();
/* Clock gate the CPU */
tegra_wait_cpu_in_reset(cpu);
tegra_disable_cpu_clock(cpu);
/* Should never return here. */
BUG();
Given that both implementations (Tegra20/30) of tegra_hotplug_shutdown
include:
bl tegra20_cpu_shutdown
mov pc, lr @ should never get here
why does tegra_cpu_die() include the calls to tegra_wait_cpu_in_reset()
and tegra_disable_cpu_clock() after calling tegra_hotplug_shutdown()?
(and how can a CPU wait for itself to be in reset anyway)?
Perhaps this is fixed by the various patches you've posted but are
awaiting being applied?
