Hi,

I was wondering if there is any value in keeping non-compiling code in the tree, hence the question. For Tegra it is straight forward, so it would be easy to pull the plug.

Hi Varun,

For Arm reference platforms, we are not sure who all are using it. That is why i proposed to keep in repo for around a year before deleting it.

But for NV platforms, if you are sure that nobody is going to require it, you can delete it earlier.

Also, instead of proposed step 2 earlier we can have an alternate

-  2. Don't allow it to be built by default. (introducing PLATFORM_DEPRECATED build macro)

+ 2. Instead of purposefully failing the build we can print a warning message (It's also quite possible that someday during cooling off period it stops to build naturally)

thanks

Manish

Hi Manish,

Just curious, what would be the reason to keep the platform alive for 2 release cycles? I have one Tegra platform that needs to be deprecated and so would like to understand the thought process.

Hi,

The purpose of the email is to notify about deprecation of sgm775 platform and proposed process for deprecating a platform.

Arm's System Guidance for Mobile(SGM-775) is an old platform and no longer maintained. It is superseded by Total Compute(tc0) platform.

Proposal for deprecating a platform:

1. Keep the code in repository. (at least for 2 release cycles)

2. Don't allow it to be built by default. (introducing PLATFORM_DEPRECATED build macro)

3. Disable CI testing.

4. Create appropriate documentation for deprecated platforms.

Let me know if you have any suggestions.

Thanks

Manish P
