[meta-fsl-arm PATCH v2 00/16] Machine overrides extender - reduce code duplication

[Otavio Salvador]

We spent some time trying to come up with something which would make
easier to extend the tune-arch support. All we could come up was way
too complex or did not work.

Instead We did a MACHINEOVERRIDES extender.

This enables the machine overrides extender for the i.MX6 devices. It
maps (spaces are used to easy the read):

  - mx6q  ->        imxipu imxvpu imxgpu2d imxgpu3d
  - mx6dl -> imxpxp imxipu imxvpu imxgpu2d imxgpu3d imxepdc
  - mx6sx -> imxpxp               imxgpu2d imxgpu3d
  - mx6sl -> imxpxp               imxgpu2d          imxepdc
  - mx6ul -> imxpxp
  - mx7d  -> imxpxp                                 imxepdc

So it allows for reusing of overrides while keeps this control at the
BSP side. For example, a PACKAGECONFIG setting which is common for
mx6q, mx6dl and mx6sx used to look as:

PACKAGECONFIG_mx6q  = "option"
PACKAGECONFIG_mx6dl = "option"

Now it can be replaced by:

PACKAGECONFIG_imxvpu = "option"

Changes in v2:
- Use BitBake event to insert the extends
- New patch.

[meta-fsl-arm PATCH v2 01/16] Convert SOC_FAMILY to MACHINEOVERRIDES

[Otavio Salvador]

The SOC_FAMILY is an indirection which makes the understanding, from
OpenEmbedded versed developers and users, more difficult. Instead of
using the SOC_FAMILY indirection which is rarely used, we now move to
the MACHINEOVERRIDES mechanism as this is in fact what is in use.

[meta-fsl-arm PATCH v2 05/16] imx-base.inc: Enable machine overrides extender for i.MX6

[Otavio Salvador]

This enables the machine overrides extender for the i.MX6 devices. It
maps (spaces are used to easy the read):

 - mx6q  ->        imxipu imxvpu imxgpu2d imxgpu3d
 - mx6dl -> imxpxp imxipu imxvpu imxgpu2d imxgpu3d imxepdc
 - mx6sx -> imxpxp               imxgpu2d imxgpu3d
 - mx6sl -> imxpxp               imxgpu2d          imxepdc
 - mx6ul -> imxpxp
 - mx7d  -> imxpxp                                 imxepdc

So it allows for reusing of overrides while keeps this control at the
BSP side.

[meta-fsl-arm PATCH v2 11/16] imx-gpu-viv: Refactor code to use the new overrides

[Otavio Salvador]

The recipe has been reworked to use the 'imxgpu2d' and 'imxgpu3d'
feature overrides. While on that, the i.MX6SL specific code has been
reworked to used when only 2D GPU support is available.

I thought the 'bare' variable was required as well, no?

IMXGPU = ""

Otherwise, I'm not sure if I understand the logic of the 2d/3d overrides. It looks like the intent is that we will have two cases, either 2d only or 2d and 3d, right? Perhaps a variable name change would make this logic a bit clearer:

IMXGPU2D_ONLY = "yes"
IMXGPU2D_ONLY_imxgpu3d = "no"

IMXGPU = "2d" or "3d" is clear enough no?

The logic looks like 'gpu has 2d', but In fact what it is doing is 'gpu does not have 3d', right? This is not clear at all.

This is a HACK! and ought to be fixed by the GPU Team; ideally we
should have different tarballs or subdirs for it. I used same logic
here as I did in Qt Base recipe.

[meta-fsl-arm PATCH v2 13/16] weston: Refactor code to use the new overrides

[Otavio Salvador]

The recipe has been reworked to use the 'imxpxp', 'imxgpu2d' and
'imxgpu3d' feature overrides. While on that, the i.MX6UL specific code
has been reworked to used when only PXP-only support is available,
fixing the i.MX7D support as well.

This doesn't look equivalent to me. It adds eglvivsink to mx6sl, right?

The i.MX BSP now defaults for XWayland when both X11 and Wayland
support is available, so we ought to use the Wayland backend for this
case as well.

Re: [meta-fsl-arm PATCH v2 00/16] Machine overrides extender - reduce code duplication

Hi Otavio,
       
This looks good, but what do you think of implementing the new items as MACHINE_FEATURES instead of overrides?

Subject: [meta-fsl-arm PATCH v2 00/16] Machine overrides extender - reduce code duplication

We spent some time trying to come up with something which would make
easier to extend the tune-arch support. All we could come up was way
too complex or did not work.

Instead We did a MACHINEOVERRIDES extender.

This enables the machine overrides extender for the i.MX6 devices. It
maps (spaces are used to easy the read):

  - mx6q  ->        imxipu imxvpu imxgpu2d imxgpu3d
  - mx6dl -> imxpxp imxipu imxvpu imxgpu2d imxgpu3d imxepdc
  - mx6sx -> imxpxp               imxgpu2d imxgpu3d
  - mx6sl -> imxpxp               imxgpu2d          imxepdc
  - mx6ul -> imxpxp
  - mx7d  -> imxpxp                                 imxepdc

So it allows for reusing of overrides while keeps this control at the
BSP side. For example, a PACKAGECONFIG setting which is common for
mx6q, mx6dl and mx6sx used to look as:

PACKAGECONFIG_mx6q  = "option"
PACKAGECONFIG_mx6dl = "option"

Now it can be replaced by:

PACKAGECONFIG_imxvpu = "option"

Changes in v2:
- Use BitBake event to insert the extends
- New patch.

It should be possible indeed however, thinking about it, I think using
overrides offers an easier to use mechanism.

For example, using the overrides we can:

PACKAGECONFIG_append_imxgpu3d = " egl"

To use the MACHINE_FEATURES we would need to use:

PACKAGECONFIG_append = " $@{bb.utils.contains('MACHINE_FEATURES',
'imxgpu3d', 'egl', '', d}"

Another benefit is that with the extender, we define the features on a
single place (imx-base.inc) and every board using the respective SoC
will use it. For machine features we would need to set it in every
board which is easy to get wrong.

It's shorter, but I don't see the difference in syntax as a problem. The 'bb.utils.contains('*FEATURES'' is an existing idiom.

The way I see it is the Yocto framework has a high level construct of machines and a finer grained mechanism for specifying the features supported by a machine.

What you are proposing is to take our list of i.MX-specific 'items' and add them through an extension of the machine mechanism. The downside of this is it dilutes the existing Yocto framework, and makes it harder to understand.

On the other hand, it seems correct to just treat these 'items' as machine features, with no changes to the existing Yocto framework required. Furthermore, by implementing this as a set of machine features, we gain the existing capabilities of the framework, mainly that the user can choose to not use an i.MX machine feature even if it is on his SOC. (See the COMBINED_FEATURES variable.)

We would need an extra require line from each machine configuration file to specify the SOC configuration. This line replaces the proposed MACHINEOVERRIDES line in the machine configuration file, and so it is no easier to get wrong.

The MACHINE_FEATURES including that kind of information will have a
huge impact on the number of machine specific package. In summary we
would not be able to share the binaries across different machines of
same SoC. Currently we share the Q, DL binaries as they are binary
compatible however if this could change on the board we would need to
make they are machine specific (Qt, Chromium, GStreamer, ...)

Not sure I understand. Those recipes work today across different machines, and it seems like using MACHINE_FEATURES doesn't change that at all. Each binary will vary only because of different machine features, so if Q and DL have the same features, the binary will still be compatible. Do I misunderstand how this works?

Yes; see the packages generated and how we enable the MACHINE_SOCARCH;
it shares binaries across same SoC families[1]

1. https://github.com/Freescale/meta-fsl-arm/blob/master/conf/machine/include/imx-base.inc#L53

So what would happens is that all recipes we have on -mx6qdl would
change and be MACHINE_ARCH. This is a bad side effect.

Okay, so now I know a little about packaging levels :-)

I found a comment in poky packagegroup_base.bb that seems relevant here. It basically says "set PACKAGE_ARCH to MACHINE_ARCH to use MACHINE_FEATURES". I guess that's why there could be a problem since we rely on MACHINE_SOCARCH for increased reuse.

However, I wonder if the rule is overstated and can be relaxed to say "set PACKAGE_ARCH to a machine-specific value to use MACHINE FEATURES". If so then we could continue to use MACHINE_SOCARCH with a MACHINE_FEATURES-based design and no loss of binary reuse.

It cannot as it would generate same package with different compile
options every time its value is changed.

To be sure I understand, when you say 'its value is changed', do you mean 'MACHINE value is changed'?

I tested the MACHINE_FEATURES idea with the following steps to see if I could detect any changes in reuse:

1. Set MACHINE=imx6qsabresd in local.conf
2. bitbake gstreamer1.0-plugins-imx imx-gst1.0-plugin
3. Set MACHINE=imx6dlsabresd in local.conf
4. bitbake gstreamer1.0-plugins-imx imx-gst1.0-plugin
5. Repeat steps 1-4 and observe behavior
6. Add MACHINE_FEATURES += "imx-vpu" to imx6qsabresd.conf and imx6dlsabresd.conf
7. Add DISTRO_FEATURES_append = " imx-vpu" to local.conf
8. Replace PACKAGECONFIG overrides in gstreamer1.0-plugins-imx_0.12.2.bb with:
PACKAGECONFIG ?= "uniaudiodec mp3encoder v4l2src g2d eglvivsink ipu \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imx-vpu', 'vpu', '', d)}"
9. Replace DEPENDS and DEPENDS_append overrides in imx-gst1.0-plugin_4.0.9.bb with:
DEPENDS = "imx-codec imx-parser virtual/kernel gstreamer1.0 gstreamer1.0-plugins-base imx-lib \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imx-vpu', 'imx-vpu imx-vpuwrap', '', d)}"
10. Repeat steps 1-5

The original implementation and the MACHINE_FEATURES implementation behaved identically as far as I could tell. No tasks were performed at step 5 when the MACHINE was changed from DL to Q and back, and packages seemed to be in the correct place for reuse:

Yes; you are :-)

The problem of the use of a machine setting is the meaning of it. It
says you can change it for every machine and you can't.

Imagine following case:

Machine A - imxgpu3d
Machine B - without imxgpu3d

and consider both are Quad. How qtbase will be build? Both will end on
cortexa9hf_neon_mx6qdl causing the package to be generated with
different contents for A and B. This is the reason I said it end being
machine specific.

This is not the meaning of a machine feature. The manual gives the definition as a "hardware feature the MACHINE is capable of supporting [1]". Note the word 'capable'. A machine feature is in fact inherent to a given machine and not something that can vary.

This example should not be implemented through MACHINE_FEATURES solely, but instead through a combination of MACHINE_FEATURES, DISTRO_FEATURES, and COMBINED_FEATURES. COMBINED_FEATURES is defined thus:

Provides a list of hardware features that are enabled in both MACHINE_FEATURES and DISTRO_FEATURES. This select list of features contains features that make sense to be controlled both at the machine and distribution configuration level. For example, the "bluetooth" feature requires hardware support but should also be optional at the distribution level, in case the hardware supports Bluetooth but you do not ever intend to use it. [2]

To express this succinctly: MACHINE_FEATURES = capability, DISTRO_FEATURES = enablement, and COMBINED_FEATURES = capability and enablement. This is how the example should be implemented:

MACHINE_FEATURES 	- contains imxgpu3d for Machine A and Machine B
DISTRO_FEATURES	- contains imxgpu3d for Machine A only
COMBINED_FEATURES	- contains imxgpu3d for Machine A only

So, different distro, different tmpdir, and no reuse problem :-)

I know how this works BUT people assumes machine features are to be
enabled/disabled on machine basis, that is the main reason I did not
use it.

The way I designed it, the extender is applied on the BSP level so it
provides the lift of features the SoC supports. If you want to change
something in a recipe or so, it will be applied globally and then
making it harder for people to make a frankenstein.

Okay, so assume we chose to implement using machine features, and a user has disabled a machine feature using MACHINE_FEATURES_remove. I guess he will have no problem (other than his faulty understanding) since the feature will be disabled as he wants. Is there some other problem?

Okay, but an implementation using MACHINE_FEATURES would not be any different. Each machine configuration file would include a new SOC configuration file, like this one for 6 Quad:

GPU_FEATURES = "imxipu imxvpu imxgpu2d imxgpu3d"
MACHINE_FEATURES += "${GPU_FEATURES}"
DISTRO_FEATURES_DEFAULT += "${GPU_FEATURES}"

And here's how the gstreamer1.0-plugins-imx recipe would set its package config:

PACKAGECONFIG ?= "uniaudiodec mp3encoder v4l2src \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imxpxp', 'pxp', '', d)} \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imxgpu2d', 'g2d', '', d)} \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imxgpu3d', 'eglvivsink', '', d)} \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imxipu', 'ipu', '', d)} \
    ${@bb.utils.contains('COMBINED_FEATURES', 'imxvpu', 'vpu', '', d)} \
"

I see no problems with this design. It provides all the required functionality, plus it relies on a well-defined, existing model for enabling and disabling hardware features.

On the other hand, the override extender design adds complexity to the implementation of MACHINE, and complicates the model by adding this new SOC type of hardware feature. Also, relying on the variable override mechanism is a weakness, as we have seen the existing SOC override design to be error-prone due to the intricacies of the override mechanism. The override extender design does reduce the use of overrides, but it seems to me like we could still have some trouble with the 2d and 3d overrides.

Adding DISTRO things in a machine file is a clear indication something
is wrong. Anything related to distro features cannot be change in
machine level or it makes it incompatible across different machines.

Yes, I wasn't sure if that would be a problem. Lauren has advocated for adding distros, and I guess that would be a better location for this. What is the latest status on that?

A BSP must be DISTRO agnostic; I won't merge something that does not
preserve that.

Okay, then that is a problem. Can we push these hardware features into poky so that they are treated identical to the other COMBINED_FEATURES?

DISTRO agnostic does not mean Poky; at O.S. Systems we have a number
of custom distros based on OE-Core.

As I said, machine features are not intended for this use.
