[PATCH 0/4] dts: Remove Excess Attributes From User Config

[PATCH 0/4] dts: Remove Excess Attributes From User Config

[Nicholas Pratte]

A good amount of the attributes listed in the conf.yaml are either
currently unused or unneeded. The goal of this patch is to eliminate
minutiea from the config that may make the overall execution process
more difficult and tedious.

It should be noted that more improvements are possible here, and
in fact, there are other improvements that can likely be made in the
future; for instance, the removal of the OS attribute, and simplication
of the port topology listings (this is currently being worked on in a
separate patch). If it is desired, and the others are okay with it,
I'd like to look into potentially getting rid of the OS attribute at
some point.

[PATCH 1/4] dts: Remove build target config and list of devices

[Nicholas Pratte]

Remove the list of devices from the schema, as these are unuesed.
Likewise, removed build-target information since these is not currently
used, and it is unlikely to be used in the future. Adjustments to the
dts.rst are made to reflect these changes.

This attribute got removed from the class, we should take it out of
the docstring too.

I'm not sure what the implications of removing this method call are,
it seems like it adds some value to the DPDK build process by adding a
CFLAG and a path to the pkgconfig directory. Maybe we don't need this,
but there might be a reason it was there originally as well.

Removed use_first_core from the conf.yaml in favor of determining this
within the framework. use_first_core continue to serve a purpose in that
it is only enabled when core 0 is explicitly provided in the
configuration. Any other configuration, including "" or "any," will
omit core 0.

Documentation reworks are included to reflect the changes made.

I think just leaving this as "defaults to 1" is fine here. It's more
explicit to say "if it isn't used", but just saying it defaults I
think implies that enough.

I wonder if we could completely remove the "use_first_core" attribute
from the config classes. It seems like it's only used when you're
getting remote CPUs to skip core 0 based on the condition. With these
new changes it seems like we just assume that if 0 is in the list, we
will use it, otherwise we simply won't, so I don't think we need this
condition to detect whether we should skip or not anymore, do we?

This condition fits if you completely remove the `use_first_core`
boolean from the NodeConfiguration, but if we decide not to I think it
could be shortened to just:

if config.use_first_core:

Good point, and you're right. '*optional* and 'if not used' are redundant.

It's an interesting point, and it's one that I honestly thought about
right after I completed the last patch in this series (DPDK_config
config attribute). It wasn't until I tried implementing the
'dpdk_config' attribute that I realized the broader scope of lcore
filtering in the framework. The framework is currently filtering a
list of lcores in two spots of the framework. The last patch, as you
saw, addresses the aforementioned problem by removing 'use_first_core'
from the framework completely.

In retrospect, I could have dropped this commit and just included the
'dpdk_config' patch with the 'use_first_core' changes included, but I
suppose it's not bad for others to see both implementations and
discuss what the better option is.

Noted, and good catch! I'll keep this in mind depending on which way
the wind blows.

[PATCH 3/4] dts: Self-Discovering Architecture Change

[Nicholas Pratte]

The 'arch' attribute in the conf.yaml is unnecessary, as this can be
readily discovered within the constructor of any given node. Since OS is
determined within user configuration, finding system arch can be done
both reliably and easily within the framework.

For Linux/Posix systems, the 'uname' command is used to determine system
architecture. I believe that this is posix-standard and utilizes a
standardized output.

[PATCH 4/4] dts: Rework DPDK Attributes In SUT Node Config

[Nicholas Pratte]

Rework 'lcores' and 'memory_channels' into a new 'dpdk_config'
subsection in an effort to make these attributes SUT specific; the
traffic generator, more often than not, does not need this information.
Ideally, if such information is needed, then it will be listed in the
'traffic_generator' component in TG Node configuration. Such logic is
not introduced in this patch, but the framework can be rewritten to do
so without any implications of extreme effort.

To make this work, use_first_core has been removed from the framework
entirely in favor of doing this within the LogicalCoreListFilter object.
Since use_first_core was only ever activated when logical core 0 was
explicitly defined, core 0 can be removed from the list of total logical
cores assuming that it was not listed within filter_specifier.

This patch also removes 'vdevs' from 'system_under_test_node' and moves
it into 'executions.'

Re: [PATCH 4/4] dts: Rework DPDK Attributes In SUT Node Config

[Jeremy Spewock]

Funny, this commit addresses a comment I had on the previous. I think
it makes a lot of sense to split the EAL parameter information into a
DPDK specific config that the TG doesn't have since it likely won't
need it.

I think it makes more sense to do this in the commit where you removed
it from the config as well and just completely take it out. There
isn't really a need to keep it in the framework in that commit so I'd
be more in favor of removing it from there entirely and then this
commit won't need to since it's less relevant here.

I don't really understand what these two conditionals are doing. if 0
is in the lcore_list, why do we need to omit the first value from the
filter list? Or if it is in the cores to filter why do we need to
remove the first element from that list? Also, is this attempting to
omit core 0 in the list? I think where it appears in the list can be
different depending on if the list is ascending or descending which is
different depending on the EAL parameters function it seems.
Regardless, can we add a comment on why this is needed?

[PATCH v2 1/6] dts: Remove build target config and list of devices

[Nicholas Pratte]

Remove the list of devices from the schema, as these are unuesed.
Likewise, removed build-target information since these is not currently
used, and it is unlikely to be used in the future. Adjustments to the
dts.rst are made to reflect these changes.

[PATCH v2 2/6] dts: Use First Core Logic Change

[Nicholas Pratte]

Removed use_first_core from the conf.yaml in favor of determining this
within the framework. use_first_core continue to serve a purpose in that
it is only enabled when core 0 is explicitly provided in the
configuration. Any other configuration, including "" or "any," will
omit core 0.

Documentation reworks are included to reflect the changes made.

[PATCH v2 3/6] dts: Self-Discovering Architecture Change

[Nicholas Pratte]

The 'arch' attribute in the conf.yaml is unnecessary, as this can be
readily discovered within the constructor of any given node. Since OS is
determined within user configuration, finding system arch can be done
both reliably and easily within the framework.

For Linux/Posix systems, the 'uname' command is used to determine system
architecture. I believe that this is posix-standard and utilizes a
standardized output.

[PATCH v2 4/6] dts: Rework DPDK Attributes In SUT Node Config

[Nicholas Pratte]

Rework 'lcores' and 'memory_channels' into a new 'dpdk_config'
subsection in an effort to make these attributes SUT specific; the
traffic generator, more often than not, does not need this information.
Ideally, if such information is needed, then it will be listed in the
'traffic_generator' component in TG Node configuration. Such logic is
not introduced in this patch, but the framework can be rewritten to do
so without any implications of extreme effort.

To make this work, use_first_core has been removed from the framework
entirely in favor of doing this within the LogicalCoreListFilter object.
Since use_first_core was only ever activated when logical core 0 was
explicitly defined, core 0 can be removed from the list of total logical
cores assuming that it was not listed within filter_specifier.

This patch also removes 'vdevs' from 'system_under_test_node' and moves
it into 'executions.'

[PATCH v2 5/6] dts: add conditional behavior for test suite

[Nicholas Pratte]

There is some odd functionality/behavior in how the --test-suite
parameters interacts in conjunction with the 'test_suites' attribute in
the config file. If a user leaves an empty list underneath
'test_suites,' or if they negate the attribute entirely, even if said
user adds test suites via the --test-suite parameter, a schema violation
is thrown.

This patch mitigates this, by removing the schema requirement if the
user has indicated test suites within main.py parameters, allowing for
the 'test_suites' attribute to be optional.

[PATCH v2 1/6] dts: Remove build target config and list of devices

[Nicholas Pratte]

Remove the list of devices from the schema, as these are unuesed.
Likewise, removed build-target information since these is not currently
used, and it is unlikely to be used in the future. Adjustments to the
dts.rst are made to reflect these changes.

Bugzilla ID: 1360

Because it's only the one attribute now this should likely just be
"`compiler` is converted to an :class:`Enum`" and because you don't
need this \s, I think you can also remove the "r" from the start of
the doc-string that makes it a string literal.

I could have sworn I fixed this before sending this out. I'll take care of it!

Re: [PATCH v2 1/6] dts: Remove build target config and list of devices

The subject line should be all lowercase (except for abbreviations and 
maybe some other exceptions).

I think we can still keep this, we can just remove arch, os and cpu 
(there could be multiple build target, each with different compiler 
(gcc, clang, etc.)). If there's a reason to remove this, it should be 
mentioned in the commit message.

Should we also remove arch that's above these two?

If we keep build_target_config.name this should be reverted.

I can do that. If I had a justification for removing this way back
when I wrote this, it wasn't strong enough for me to remember. I don't
mind leaving this in.

[PATCH v2 2/6] dts: Use First Core Logic Change

[Nicholas Pratte]

Removed use_first_core from the conf.yaml in favor of determining this
within the framework. use_first_core continue to serve a purpose in that
it is only enabled when core 0 is explicitly provided in the
configuration. Any other configuration, including "" or "any," will
omit core 0.

Documentation reworks are included to reflect the changes made.

The message in parentheses could be confusing, let's make it explicit 
that an empty string skips first core.

And the comments in this file are all lowercase so let's do that in 
parentheses as well.

I'm wondering whether we want to do this in config. The logic seems to 
be better placed elsewhere. My thinking is this:
1. Removing use_first_core from Node._get_remote_cpus() (and the 
downstream OSSession methods) makes sense since the method really looks 
like it should be getting all remote CPUs. A benefit here is the first 
core filtering doesn't happen in OSSession where it currently is - it 
just doesn't make sense there.
2. Putting use_first_core to LogicalCoreList also doesn't make much 
sense, it's supposed to be a list and not supposed to do any filtering.
3. The two above are used to compose the final list of usable cores on a 
node. We could either filter the first core from 1. after getting the 
cores, we could filter it from 2. after getting the core list or filter 
it after using 1. and 2. with LogicalCoreListFilter().

Or in other words:
remote_lcores = self.main_session.get_remote_cpus()
lcore_list_config = LogicalCoreList(self.config.lcores)
self.lcores = LogicalCoreListFilter(remote_lcores, 
lcore_list_config).filter()

We can either remove the first core from remote_lcores, 
lcore_list_config or from self.lcores. The result is the same if we 
remove it from any of these, so maybe we just work with self.lcores as 
that is also what you've used in the patch to issue the warning.

The logic of whether to remove the core or not would be in Node (if 
self.config.lcores is either "" or "any").

[PATCH v2 3/6] dts: Self-Discovering Architecture Change

[Nicholas Pratte]

The 'arch' attribute in the conf.yaml is unnecessary, as this can be
readily discovered within the constructor of any given node. Since OS is
determined within user configuration, finding system arch can be done
both reliably and easily within the framework.

For Linux/Posix systems, the 'uname' command is used to determine system
architecture. I believe that this is posix-standard and utilizes a
standardized output.

 From what I can tell, uname is it POSIX compliant. Let's reword this to 
remove the uncertainty.

I'd rename this to just get_arch(), as get_arch_info implies we're 
getting more than just a string representation of the archirecture.

[PATCH v2 4/6] dts: Rework DPDK Attributes In SUT Node Config

[Nicholas Pratte]

Rework 'lcores' and 'memory_channels' into a new 'dpdk_config'
subsection in an effort to make these attributes SUT specific; the
traffic generator, more often than not, does not need this information.
Ideally, if such information is needed, then it will be listed in the
'traffic_generator' component in TG Node configuration. Such logic is
not introduced in this patch, but the framework can be rewritten to do
so without any implications of extreme effort.

To make this work, use_first_core has been removed from the framework
entirely in favor of doing this within the LogicalCoreListFilter object.
Since use_first_core was only ever activated when logical core 0 was
explicitly defined, core 0 can be removed from the list of total logical
cores assuming that it was not listed within filter_specifier.

This patch also removes 'vdevs' from 'system_under_test_node' and moves
it into 'executions.'

I see you actually did what I was thinking of. This should be in 2/6.

I'm not a big fan of two different implementation of what should be 
common logic. Can we pass skip_first_core to 
LogicalCoreFilter.__init__() and remove the first core from 
self._lcores_to_filter if True (it would default to False)? skip_first 
core would be determined in SutNode.__init__() and then passed downstream.

Here is where we could determine use_first_core from 
self.config.dpdk_config.lcores and pass that to self.filter_lcores().

[PATCH v2 5/6] dts: add conditional behavior for test suite

[Nicholas Pratte]

There is some odd functionality/behavior in how the --test-suite
parameters interacts in conjunction with the 'test_suites' attribute in
the config file. If a user leaves an empty list underneath
'test_suites,' or if they negate the attribute entirely, even if said
user adds test suites via the --test-suite parameter, a schema violation
is thrown.

This patch mitigates this, by removing the schema requirement if the
user has indicated test suites within main.py parameters, allowing for
the 'test_suites' attribute to be optional.

Re: [PATCH v2 5/6] dts: add conditional behavior for test suite

[Jeremy Spewock]

I think it makes sense to allow users to not specify any test suites
in the config file if they specify them through other means, so I like
this change.

Nice idea, doesn't look like there's any hard in adding it. Should we 
document this (the fact that it could be optional under certain 
circumstances) somewhere, like add something to the description in schema?

The variable should maybe contain that these test suites are not from 
config_file_path. Maybe just rename to other_test_suites? Or something 
like that.

Also, it needs to be added to Args:

Looking at the changes to conf.yaml, looks like there are missing pieces 
(such as moved vdevs and memory_channels), but the patch no longer 
applies and it's hard to verify without that. But this is likely not 
needed because the Pydantic changes are going to simplify this.

[PATCH v2 1/6] dts: Remove build target config and list of devices

[Nicholas Pratte]

Remove the list of devices from the schema, as these are unuesed.
Likewise, removed build-target information since these is not currently
used, and it is unlikely to be used in the future. Adjustments to the
dts.rst are made to reflect these changes.
