  To: dev; +Cc: david.hunt, stable, Bruce Richardson

From: Bruce Richardson <bruce.richardson@intel.com>

The guest channel message definitions and commands in guest_channel.h file
are needed by applications and need to be made public.

This patch is needed because make is broken for the power_mgmt apps, as
the channel commands API is private. This previously built within DPDK,
but now with all the meson/ninja changes, making these apps externally
no longer works. To fix, we need to move the header file with the API
definitions for the channel commands public, and rename the functionss
accordingly.

The main change is to rename channel_commands.h to
rte_power_guest_channel.h so that it gets picked up by the installer and
copied to /usr/local/include. Other changes include renaming #defines to
have RTE_ at the beginning instead of CPU_. Finally we refactor the code
to work with those changes.

Fixes: 210c383e247b ("power: packet format for vm power management")
Fixes: cd0d5547e873 ("power: vm communication channels in guest")

The power example applications that uses the virtio-serial method of
communication cannot currently be built with make, and can only be built
using meson/ninja.

The guest channel message definitions and functions in guest_channel.h
are needed by applications and need to be made public.

This worked pre-20.11, but now with all the meson/ninja changes, making
these apps externally no longer works. To fix, we need to move the header
file with the API definitions for the channel commands public, and rename
the functions accordingly.

The main change is to rename channel_commands.h to
rte_power_guest_channel.h so that it gets picked up by the installer and
copied to /usr/local/include. Other changes include renaming #defines to
have RTE_ at the beginning instead of CPU_. Finally we refactor the code
to work with those changes.

In preparation for making the header file public, we first rename
channel_commands.h as rte_power_guest_channel.h.

Just a general question: wouldn't it be better to move this stuff 
entirely into sample app and not bother with keeping it in the library? 
There is precedent - ethtool app has a "library" and an "application" 
part, i think you should be able to move it out of the library and into 
the sample app entirely without too much trouble, as code looks to be 
fairly self-contained.

Agreed, that's a great idea. I could have a common lib under 
examples/vm_power_manager, then two apps, vm_power_manager and 
guest_cli. That would keep everything nicely local, and not expose the 
channel API publicly. The only reason we were making it public was to 
allow "make" to work, so that's not a good enought reason, tbh. I'll 
throw a prototype together today.

Thanks,
Dave.

Yep, IIRC Make works perfectly fine with ethtool, so i don't see why it 
wouldn't work for your sample app as well. Thanks!

Hi Anatoly,

OK, so I was investigating this, and have come across a blocker on this 
method.

There are three methods for managing frequency, acpi, pstate and vm. 
It's the third method that's causing the problem with moving the channel 
functionality out into a sample library alongside vm_power_manger. VM's 
can call channel functions in the power library to affect frequency for 
their cores, and these functions use api function calls and several 
structures and #defines in their code, which is currently part of the 
power management library. These function declarations, structs and 
#defines ere needed in both the examples lib/apps and the power library 
itself, and the prototype changes I made ended up looking very much like 
the patch set that's already on the mailing list.

So, while I would have liked to have a solution along the lines of what 
you've proposed, it's not possible based on the dependencies on common 
structues and #defines.

Thanks for the suggestion, though.

Rgds,
Dave.

OK, i guess we can live with that. I wonder if there's another way to do 
this, but since i can't think of anything that doesn't involve serious 
API/ABI breakages, this is OK IMO.

Why only the second one is experimental?

Given the uncertainty of this API, I think it should be all experimental.

Yes Thomas, both should be experimental. I'll fix that in the next version.

The guest channel message definitions and functions in guest_channel.h
are needed by applications and need to be made public.

This worked pre-20.11, but now with all the meson/ninja changes, making
these apps externally no longer works. To fix, we need to move the
header file with the API definitions for the channel commands public,
and rename the functions accordingly.

The main change is to rename channel_commands.h to
rte_power_guest_channel.h so that it gets picked up by the installer
and copied to /usr/local/include. Other changes include renaming #defines
to have RTE_ at the beginning instead of CPU_. Finally we refactor the
code to work with those changes.

---
v2 changes
  - re-worked from monolithic patch to a 6 patch patchset for easier review
v3 changes
  - Ensure both functions added to the API are tagged as experimental

In preparation for making the header file public, we first rename
channel_commands.h as rte_power_guest_channel.h.

Nitpick, but we generally add a warning to experimental functions, like so:

  * @warning
  * @b EXPERIMENTAL: this API may change, or be removed, without prior 
notice.

also, presumably this is not meant to be public API and exists solely 
because there's no other way to do it without significant rework, so 
maybe mark as @internal too?

Here and in other places where you do sizeof(), you might want to avoid 
future changes by replacing it with sizeof(*pkt) instead?

IMO this should be part of the first patch, otherwise the build could 
(will?) be broken until this patch.

Hi Anatoly,

    It was broken before this patch set. I wanted to have everything in 
place, including the correct naming of structs/defines before allowing 
builds against the new header file, hence this order in the patch set.

Rgds,

Dave.

Since things were already broken before the set, I'm not sure this really
matters.

It's only my opinion obviously, but i rather prefer an approach of 
fixing build issues first, and then renaming everything, as I like to 
have each patch build at every step of the way. You probably know 
better, but from a cursory look, you should be able to keep 
progressively changing things but also keep everything building 
correctly every step of the way.

I'll keep that in mind for future patch sets. For this one, the effort 
to change far outweighs the benefits, so I'll leave as is. OK with you?

The guest channel message definitions and functions in guest_channel.h
are needed by applications and need to be made public.

This worked pre-20.11, but now with all the meson/ninja changes, making
these apps externally no longer works. To fix, we need to move the
header file with the API definitions for the channel commands public,
and rename the functions accordingly.

The main change is to rename channel_commands.h to
rte_power_guest_channel.h so that it gets picked up by the installer
and copied to /usr/local/include. Other changes include renaming #defines
to have RTE_ at the beginning instead of CPU_. Finally we refactor the
code to work with those changes.

---
v2 changes
 - re-worked from monolithic patch to a 6 patch patchset for easier review
v3 changes
  - Ensure both functions added to the API are tagged as experimental
v4 changes
  - add @internal tag on 2 functions for Doxygen
  - add @warning EXPERIMENTAL tag on 2 functions for Doxygen
  - improve description of lcore param in API docs
  - Improve maintainability sizeof's
  - add the 2 added functions to the version.map file

From: Bruce Richardson <bruce.richardson@intel.com>

rename the public structs to have an rte_power_ prefix and
add them to version.map in experimental section.

Fixes: 210c383e247b ("power: packet format for vm power management")
Fixes: cd0d5547e873 ("power: vm communication channels in guest")
Cc: stable@dpdk.org

Nitpick but you left an extra newline there :) can probably be fixed on

These and other defines are in public header, and they're not under RTE_ 
namespace. To avoid clashes with user code, I would suggest either 
adding an RTE_ prefix, or maybe #undef'ing them at the end of the file.

Apologies, didn't realize this was in the next patch :D (also, #undef 
was a bad idea...)

The guest channel message definitions and functions in guest_channel.h
are needed by applications and need to be made public.

This worked pre-20.11, but now with all the meson/ninja changes, making
these apps externally no longer works. To fix, we need to move the
header file with the API definitions for the channel commands public,
and rename the functions accordingly.

The main change is to rename channel_commands.h to
rte_power_guest_channel.h so that it gets picked up by the installer
and copied to /usr/local/include. Other changes include renaming #defines
to have RTE_ at the beginning instead of CPU_. Finally we refactor the
code to work with those changes.

---
v2 changes
 - re-worked from monolithic patch to a 6 patch patchset for easier review
v3 changes
  - Ensure both functions added to the API are tagged as experimental
v4 changes
  - add @internal tag on 2 functions for Doxygen
  - add @warning EXPERIMENTAL tag on 2 functions for Doxygen
  - improve description of lcore param in API docs
  - Improve maintainability sizeof's
  - add the 2 added functions to the version.map file
v5 changes
  - moved version.map additions from patch 3 to patch 2

In preparation for making the header file public, we first rename
channel_commands.h as rte_power_guest_channel.h.

  To: dev; +Cc: david.hunt, stable, Bruce Richardson

From: Bruce Richardson <bruce.richardson@intel.com>

Adjust meson.build so that 'ninja install' copies the new header
file into the installation directory.

Fixes: 210c383e247b ("power: packet format for vm power management")
Fixes: cd0d5547e873 ("power: vm communication channels in guest")

I already applied a modified v4 with the changes requested by Anatoly that you missed in this v5.

As far as I can see these function are public, so why they have '@internal' tag?

These two new symbols are already in the .map file, which is causing a build 
error [1], need to remove the duplicate.

And one of the above symbols is already in the non-experimental section, I guess 
that was a mistake but just to double check, we are not downgrading an existing 
mature API to experimental API, right?

This is also causing build error, like:
https://travis-ci.com/github/ovsrobot/dpdk/jobs/482121104

Also '@internal' marker removed from doxygen comment, since public API
should not be internal.

Hi Ferruh,

Thanks for taking a stab at this.  I think there isn't such a simple
solution, because this change causes an ABI failure (for some reason)
like:

  [D] 'function int rte_power_guest_channel_send_msg(channel_packet*, unsigned int)'    {rte_power_guest_channel_send_msg@@DPDK_21}

I guess we might need the full type of aliasing solution documented in
Ulrich Drepper's paper https://www.akkadia.org/drepper/dsohowto.pdf

That will really need someone who knows what the symbols should look
like based on the ABI / API for the different versions.  WDYT?

This symbol was marked stable so far.
Did I miss something?
I would just remove the experimental tagging for this symbol which is
incorrect in v21.02.

Sidenote, we can probably catch these duplicates during build.
For duplicate entries with the same version, this is easy.
I'll see if I can catch the other case too.

You are right,

The header that has the declares the API was not public before the v21.02, so I 
assumed the symbol is internal and added to the stable section by mistake, but 
the intention seems to have it as public API.

I will keep the 'rte_power_guest_channel_send_msg' API, but 
'rte_power_guest_channel_receive_msg' is already experimental, so will keep it 
as it is.

Wasn't there a script for it already, I slightly remember it but not sure, cc'ed 
Thomas, perhaps he remembers.

Also '@internal' marker removed from doxygen comment, since public API
