ACPI always sets txfifo and rxfifo to 32. This configuration will
cause problem if the IP core supports a fifo size of less than 32.
The driver should read the fifo size from the IP and select the
smaller one of the two.

Hello,
This picks up some work from a while back that adds pinctrl and GPIO support to
the Aspeed devicetrees. See the previous series:
https://lkml.org/lkml/2016/8/30/74
Since v3 two new patches have been added, describing the Low Pin Count bus and
SoC Display Controller nodes. These are es

The is_idle_sample() function actually does more than determining
whether sample come from idle task. Split the callchain part into
save_task_callchain() to make it clearer. Also checking prev_pid from
trace data looks unnecessary since it should be always same as
sample->pid.

The callchain_cursor__copy() function is to save current callchain
captured by a cursor. It'll be used to keep callchains when switching
to idle task for each cpu.

The struct idle_time_data is to keep idle stats with callchains entering
to the idle task. The normal thread_runtime calculation is done
transparently since it extends the struct thread_runtime.

In order to investigate reason of idle, it needs to keep the callchains
when entering to idle. This can be identified sched_switch event having
next_pid as 0.

Sometimes it only focuses on idle-related events like upcoming idle-hist
feature. In this case we don't want to see other event to reduce noise.

When --idle-hist option is used with --summary, it now shows idle stats
with callchains like below:
Idle stats by callchain:
CPU 0: 902.195 msec
Idle time (msec) Count Callchains
--
370
The --idle-hist option is to analyze system idle state so which process
makes cpu to go idle. If this option is specified, non-idle events will
be skipped and processes switching to/from idle will be shown.
This option is mostly useful when used with --summary(-only) option. In
the idle-time sum
1 - 100 of 884 matches
