In some cases, there are too much userspace high priority RT threads, which
cause kernel RT threads or kworkers block too long time. This config separate
kernel and userspace RT threads into two priority regions, priority 0~49 for
kernel and priority 50~99 for userspace, so that kernel RT threads is always
higher priority than userspace. This config also set RT policy for kworkers.

This patch fix following two cases dwc2 resume does not recognize
peripherals.
1. plug in device after system suspend, then press the power-on
button to wake up,at this time the dr_mode is OTG, op_state is
still Peripheral, the Bit[0] of GINTSTS is 1 and the port power
is off, dwc2 will not resume at this time.
2. plug in device then press the power-on button to put the system
to sleep, then we press the power-on button to wake up the system,
At this time, the dr_mode is OTG, op_state is still Host, the Bit[0]
of GINTSTS is 1, dwc2 will not resume and working abnormally.
To resolve the first exception, we should call the dwc2_hsotg_resume()
directly to resume dwc2. To resolve the second exception, if the dwc2
is lost power during suspend like RK3326S platform, wo should reinit
the core to device mode, and after do dwc2_hsotg_resume, it can trigger
the ID status change interrupt if the OTG cable is still connect. Then
we can init it for host mode in the ID status change interrupt handler.
We can use the power on bit of Hprt register to distinguish whether
it is lost power during suspend.

UVC Header in the encoded image, this patch improve the uvc
driver to support zero copy for uvc formats MJPEG/H264/H265,
and no support zero copy for YUYV.
By default, the uvc driver disable the zero copy, you can

to enable the zero copy.

--> update win format
--> update win address
---> here maybe meet vop hardware frame start, and triggle some config take affect.
---> as only some config take affect, this maybe lead to iommu pagefault.
--> update win size
--> update win other parameters
-> config done
so we add vop2_wait_for_fs_by_done_bit_status() to make sure the first config done take

Interactive governor has lived in Android sources for a very long time
and this commit is based on the code present in following branch:
https://android.googlesource.com/kernel/common android-4.4
The Interactive governor is designed for latency-sensitive workloads,
such as interactive user interfaces like the mobile phones and tablets.
The interactive governor aims to be significantly more responsive to
ramp CPU quickly up when CPU-intensive activity begins.
Existing governors sample CPU load at a particular rate, typically every
X ms and then update the frequency from a work-handler. This can lead
to under-powering UI threads for the period of time during which the
user begins interacting with a previously-idle system until the next
sample period happens.
The 'interactive' governor uses a different approach.
A real-time thread is used for scaling up, giving the remaining tasks
the CPU performance benefit, unlike existing governors which are more
likely to schedule ramp-up work to occur after your performance starved
tasks have completed.
The Android version of interactive governor also checks whether to scale
the CPU frequency up soon after coming out of idle. When the CPU comes
out of idle, the governor check if the CPU sampling is overdue or not.
If yes, it immediately starts the sampling. Otherwise, the utilization
hooks from the scheduler handle the sampling later. If the CPU is very
busy from exiting idle to when the evaluation happens, then it assumes
that the CPU is under-powered and ramps it to MAX speed.
If the CPU was not sufficiently busy to immediately ramp to MAX speed,
then the governor evaluates the CPU load since the last speed
adjustment, choosing the highest value between that longer-term load or
the short-term load since idle exit to determine the CPU speed to ramp
to.
The core of this code is written and maintained (in Android
repositories) by Mike Chan and Todd Poyner over a long period of time.
Vireshk has made changes to to the governor to align it with the current
practices followed with mainline governors, like using utilization hooks
from the scheduler and handling kobject (for governor's sysfs directory)
in a race free manner. And of course this included general cleanup of
the governor as well.

When CPU idle is enabled, the idle call should also notify the
idle_notifier_call_chain of the change in status. Otherwise some
processes will think the CPU is always active.

Current policy:
If there are two pending config done vp, and one of them is
at critical time zone, wait for the one which has long time
to vsync.
This may lead a very long wait, for example: VP0 is 3840 x 2160,
VP2 is 1920 x 1080, they are all have pending cfg done bits,
and the vcnt of VP0 is 1367, the vcnt of VP2 is 995, VP2 is
at the critical time zone, we will wait VP0 vsync(almost half frame time)
according to this policy. This lead a very long wait.
The new policy:
If there are two pending config done vp, and one of them is
at critical time zone, compare the left vcnt time of the
two vp:
if (first_vp_left_time > second_vp_left_time) {
if ((first_vp_left_time - second_vp_left_time) > first_vp_safe_time)
wait_vp = second_done_vp;
else
wait_vp = first_done_vp;
} else {
if ((second_vp_left_time - first_vp_left_time) > second_vp_safe_time)
wait_vp = first_done_vp;
else
wait_vp = second_done_vp;
}
