Hello Mark,
I wrote to Peter Huang at UniSOC
Did you ever get a chance to try the Linaro patches? Did they work for
you?

we have tried these patches, and they works. [snip]
And Baolin also suggests that his patch is too complicated and difficult
to maintain, and a better solution is list as below, this new patch I have not tried.

It is hard for me to extract the relevant patches from those emails.
I would love to finish this project but I am not sure how. It seems we need to:
1) Evaluate the patches that Baolin suggests as a simpler alternative.
2) Test them in an Android kernel with AAudio MMAP.
If you can provide a clear description of the latest set of patches then maybe I can work with someone in-house to test this.
I am open to suggestions.

Hello Mark,
Thank you for keeping this moving forward.
We sent the patches out to several SOC vendors for Android last year. They thanked us and said they would send feedback but never did. I pinged them again.
If we cannot get the changes tested by partners then I will try to get them tested internally.
For reference, this is being tracked internally at b/119712034 https://buganizer.corp.google.com/119712034
Thanks, Phil Burk

Hello Takashi,
Sorry for the late reply. I got pulled off on some other projects.
We will try to test this in-house but we will need Qualcomm's help. I will also try to get some of our SOC partners to help with testing.
Did anything ever happen with this testing? These anonymous mmap patches never got merged.
