Re: [PATCH] Change timer interrupt to edge sensitive

[Silvan Murer <silvan.murer@gmail.com>]

Hi Thor,

Did you saw my patch? I think the default configuration for the timer interrupt should be <1 13 0xf01>

Otherwise, the driver get the error "GIC: PPI13 is secure or misconfigured"

Base on the ARM documentation it is a edge sensitive trigger:
http://infocenter.arm.com/help/topic/com.arm.doc.ddi0407f/CCHEIGIC.html

Or do I understand something wrong?

Best regards,
Silvan
