I see. Thanks for the info.
So by default, the root task has complete control over physical address
containing gpt data.
And if I want to use the gpt inside a different task, the root task has to
pass its capability to that task.
Without that, any non-root task wouldnt be able to access it.
Am I understanding the timer's capability access control correctly?

Thanks Anna.
We are looking for a way to get timestamp (wall clock) that can be used in
the userland for authenticating an incoming message from remote server.
I see that the real-time clock driver is not implemented yet but an
accurate timer would do the job too.
So any recommendation on which timer implementation to use?
Would this one work?

Hi,
I was wondering if there's any real time clock implementation for I.MX6
in sel4.
And if there isnt any, what would be the best way to use a timer in sel4
(since I saw many implementations of those)?
through sel4platsupport_get_default_timer?
Best,
Oak
