In android N it is no longer allowed to trigger a media refresh of a directory
without root, therefore this method has been added to trigger a refresh of an
individual file.
Previously AndroidPerfWorkload broadcast media mounted unconditionally
inside push_assets and delete_assets. This change makes it so the
broadcast only happens if something was actually pushed/needs to be
delete.
rt-app inserts its own classifiers into the results. Previosly, if was
replacing the existing classifier if there were any. Now, classifiers
are updated, rather than replaced.
`set_sysfile_values` now accepts a `^` symbol prefixed to the
file path to indicated that the value should be written as binary data.
To accommodate this an extra `binary` flag has been added to the `set_sysfile_value`and `get_sysfile_value` methods to write and retrieve the binary data respectively.
This commit resolves a couple of issues that were causing impropper
cluster shutdown tracking in the cpustates script.
- requested_states in the PowerStateProcessor was being initalized to -1
instead of None if no state was requested; the later checks are
against None.
- requested_states was not being set if the request could be satisfied
immediately, and was being cleared upon being statisfied at a later
time. This caused a problem when a core leaves idle and then tries to
re-enter cluster shutdown. Here is an example sequence of events that
illustrates the issue (assume core0 and core1 are the only two cores
on a cluster):
1. both cores are running
2. core0 requests cluster-sleep. As core1 is running, it
is put into core-sleep instead, and its request is saved.
3. core1 requests cluster-sleep. As core0 has a pending request
for cluster-sleep, both cores are put into cluster-sleep and
the pending request is cleared.
4. core1 becomes active. core0 is elevated to core-sleep.
5. core1 tries to enter cluster-sleep. Since core0 is currently
in core-sleep (and its prior request has laredy been
cleared), core1 is put into core-sleep instead, and its
request is saved. This is an ERROR as but cores have in fact
requested cluster-sleep at this stage.
If, in step 4., core0 becomes active instead, exactly the same
situation will result, as core1 was put into cluster-sleep immediately
and its request was never saved.
Idle state requests are now always tracked on entry and are only
cleared when the core leave idle.
- Also removed a pointless identy assignment.
Added an option to generate a timeline of state transitions, in
contrast to the existing timeline of computed states. This is primarily
intended for debugging of the latter, but may also be useful for certain
kinds of analyses.

Due to a change in the parameter kind we have to update the googleplaybooks workload to work with integers for page numbers as opposed to strings.
This was missed in the previous update: 8f12066
Fixed being unable to find the 'update status' box.
Now selects a 'do you know' notification rather than the latest,
as this is now a link on how to upgrade the app which opens in
external browser.
This changeset adds the ability to sleep on the device via a
device.sleep() method. This invokes sleep on the target device. This
is useful for situations where the passage of time on the target
device does not match that of the host, e.g., gem5.
This changeset also updates a number of workloads to use this new
sleep method.
For historical reasons audio and video workloads were launching the
browser as part of their setup. This is no longer necessary. Not only
that, since on recent devices the default Android browser is missing,
this causes problems with the workloads. This commit removes the browser
launch.
In Android M and above, there is a new method of collecting fps
statistics, using gfxinfo rather than SurfaceFlinger, but the
SF method is still available however.
This parameter lets the user decide whether to always use SF,
or to allow the instrument to pick the best method based on
Android version it detects.
To work around appshare requiring access to protected variables of a workload,
a `setWorkloadParameters` method has been added to manually supply a parameter
bundle, and a `getPackageID` method to retrieve a workloads package ID.
- "remote" getter priority reduced to be below "environment" so that
resouces placed into "~/.workload_automation/dependencies" by the user
take priority over those pulled from remote locations.
- "filer" getter now uses a cache location for the resource rather than
downloading to the local resource location.
Each workload has be modfied to remove the old manual paremeter conversion
and instead to retrieve the desired type from the parameter bundle directly.
To prevent parameters having to be converted individually for each worload
the getParams() function has been overridden to perform the required type and
url decoding on the passed parameter bundle before passing the correctly typed
bundle to the workloads.
Due to the limitations of UiAutomator, parameters are not allowed to contain
certain characters including spaces and newlines when passed on the command line.
The python UiAutomatorWorkload baseclasse has been updated to use a
ParameterDict when storing workload parameters.
A new 'ParameterDict' has been added that automatically encodes and
decodes values when they are store in a dictionary. The dictionary uses 2 characters
prefixed to each value to store the original type information, e.g. 'fl' -> list of
floats, before being passed through a url encoder. The reverse process happens on retrieval.
To access the encoded values an `iterEncodedItems` and `getEncodedValue` methods have been added.
The appropriate unit tests have also been added.
