Add hostid entry, as reported by busybox's hostid applet, to TargetInfo.
This is intended to be a "unique 32-bit identifier for the current
machine". In practice, it may not be set, or may be generated from
something like an IP address, so may not be unique. However, if set, it
is still likely to be more unique than kernel/os version so may be worth
recording.
Replace Target.cpuinfo, which contained parsed contents of
/proc/cpuinfo, with a list of more comprehensive CpuInfo objects which
include cpufreq and cpuidle information as well.
- Add SimpleTargetDescriptor that simply returns a global list of target
descriptions.
- Add create_target_description function to populate that list with a
description crated from the specified components.
- Add add_description_for_target helper function to create a description
for the specified target class, and specified components. For
components that are not explicitly specified, attempt to guess
sensible defaults based on the target class' bases.
- fix TargetDescription._set to set lists rather than dicts for params
to be consistent with how params are set after creation (should
probably get rid of this entirely...)
- fix the comment describing the structure of TARGETS
If a target error occurs, check whether the target is unresponsive. If
it is, attempt to hard reset it if possible, or gracefully terminate
execution if not.
Add a method to check that the target is still responsive, and cache
the value so that the target does not need to be repeatedly probed
during various stages of wrapping up execution.
Rename the `start` method to `run` as this is what is what is called
by the threading module's `start` method, otherwise this causes the
polling to be done in the main thread blocking execution.
Allows setting of select android runtime configuration for devices running
chromeos and which support android. Currently only 'brightness' is functioning
correctly therefore the other parameters are only enable for standard android devices.
Previously when validating cpufreq runtime parameters it would check too
early whether the cpu was online, not allowing for the fact that the cpu
might be being onlined before the parameter was committed to the device.
Fix the setting of runtime parameters when the casing of the parameter in
the agenda does not match the "canonical" casing.
To make the writing of agendas easier, the casing of the parameters is
supposed to be ignored. To achieve this, parameter names are converted to
caseless_string type before they are looked up.
caseless_string's do not work with dicts. Both __contains__ (used for
the "in" operator) and __getitem__ (used for the [] operator) implement
hash-based look up, and it is not possible to have a caseless_string
match against multiple hashes to cover the different casing
possibilities.
So instead, iterate over the items in parameters dict, comparing the
caseless_string name to the key, and returning the value if it matches.
use the new get_target_description() when initializing the target inside
TargetManager, instead of manually searching through results of
list_target_descriptions().
Fix TargetInfo.from_pod(). As part of creating the POD, some of devlib's
classes such as Cpuinfo, get serialized. Since they are from devlib,
they do not implement WA's serialization interface, and are instead
serialized by extracting their internal structures. They are then not
deserialized properly, since their __init__'s expect text rather than
parsed structures.
This implements deserialization functions for these classes which
initialize them properly from TargetInfo POD.
- Use get_config_point_map() to ensure aliases are parsed from
configuraiton.
- Only set the default for a name only if it matches the corresponding
param's name (i.e. don't set for alises).
Some targets need more than 5 seconds to re-connect to a wifi network
after disabling airplane mode. To fix that, poll for network up to 20
seconds and show a warning if unreachable.
The generic "frequency" runtime parameter was only being set when there
are common frequences between avialable cores. It should always be set,
even if there are no frequencies in common, as it still valid to use it
with special values "min" and "max", in which case it should resolve
correctly to the appropriate frequencies.
This enables you to do things like:
global:
runtime_parameters:
airplane_mode: true # This improves repeatability of energy measurements
workloads:
- name: foo
- name: bar
- name: geekbench
runtime_parameters:
airplane_mode: false # Geekbench requires network, and we don't care
# about energy for that workload anyway
- Make sure TargetManager.finalize() actually gets called at the end
of the run.
- Overrule the "diconnect" parameter behavior for gem5 and make sure it
always disconnects. This necessary for stats to be generated properly.
Gem5Platform requires a host output directory as one if it's
instantiation parameters. This is not something we want to expose a
configuration parameter to the user, as for WA, the standard output
directory ought to be used.
Up to this point, WA's target instatiation process assumed that all
parameters came from the user, and there was no way for WA itself to set
them. This commit adds extra_platform_parms argument to
instantiate_target, to remedi this.
extra_platform_parms is then used to set the host output directory for
gem5 appropriately.
(linux|android)_gem5 devices were being described as having gem5
platforms but standard linux/android connections. This commit fixes this
by making sure that the gem5 connection is used.
Runtime param names from config were matched against names available on
for the target using an overly-loose regex that resulted in the wrong
config point being returned.
Use caseless_string matching instead.
Connection settings were not being properly extracted from device_config
and not used. Meaning it was impossible to e.g. specify the adb device
to use for a run.
This ensures that connection settings are extracted, validated, and used
properly.
